1. Description of a new genus and species of Satyrid^. 

By W. Hewitson, Esq. 

The genus Corades, which Mr. E. Doubleday has named and kindly 
characterized for me, comprises but few species of butterflies, most 
of which are of recent occurrence. They are from the mountainous 
districts of Columbia and Venezuela, where, like our European Hip- 
parchias of the same family, they delight in the alpine districts. 
They are remarkable for having the anal angle of the lower wings 
more or less produced into a tail. 

Genus Corades, Boisd. MSS. 

Head of moderate width, hairy; maxillae about two-thirds the 
length of the body, rather slender. Labial palpi porrect, ascending, 
longer than the head, clothed with hairs and scales, the scales at the

back of the second joint forming a tuft before the apex. First joint 
short, subcylindric, curved, stoutest at the base. Second joint three 
times the length of the first, subcylindric, slightly curved at the base, 
incrassated towards the apex, which is truncate. Third joint slen- 
derer than the second, about half its length, nearly cylindric, obtuse 
at the apex. Eyes nearly round, not very prominent, smooth. An- 
tennae less than two-thirds the length of the body, slender, grooved 
below, thickening gradually into a slender obtuse club. 

Thorax moderately stout. Anterior wings subtriangular ; the an- 
terior margin slightly arched, the outer nearly straight, three-fifths 
the length of the anterior ; inner margin nearly straight, four-fifths 
the length of the anterior. Costal nervule swollen at its origin, ter- 
minating beyond the middle of the anterior margin ; subcostal ner- 
vure rather slender, throwing off its first nervule at a short distance 
before, its second immediately before the end of the cell, the third at 
a point about as far beyond the end of the cell as the origin of the 
first is before it, its fourth about as far beyond the third as the origin 
of this last is distant from the origin of the second. Fourth sub- 
costal nervule terminating at the apex of the wing : upper disco- 
cellular nervule very short ; middle and lower disco-cellular nervules 
about equal, the former curved inwards, the latter outwards ; a rudi- 
mentary discoidal nervule extending inwards from the middle disco- 
cellular nervule : median nervure swollen at its base, its third nervule 
bent at a considerable angle where it is joined by the lower disco- 
cellular : submedian nervure stout, curved near the base : internal 
nervure wanting. Posterior wings obovate, produced into a short 
tail at the anal angle ; the anterior margin nearly straight, the outer 
much curved ; the abdominal fold ample. Precostal nervule stout, 
curved inwards : costal nervure rather stout, curved at its origin : 
subcostal nervure rather stout, bent at a considerable angle where 
the costal separates from it ; its second nervule angular where the 
straight upper disco-cellular nervule anastomoses with it. Discoidal 
nervule extending into the cell : lower disco-cellular nervule straight, 
longer than the upper, anastomosing with the discoidal nervure a long 
way beyond the anastomosis of the upper disco-cellular. Third me- 
dian nervule bent at nearly a right angle where the lower disco- 
cellular anastomoses with it. Anterior legs of the male slender, 
thinly clothed with scales and long delicate hairs ; the femur rather 
shorter than the tibia ; the tarsus little more than two-thirds the 
length of the tibia, one-jointed, nearly cylindric. Anterior legs of 
the female rather slender, clothed with scales and a few long fine 
hairs. Femur and tibia of about equal length, the latter nearly cy- 
lindric ; the apex slightly stoutest, thinly spiny both within and with- 
out. Tarsus shorter than the tibia, five-jointed, the first joint more 
than twice the length of the rest combined ; these all transverse : 
first to fourth bispinose at the apex ; second and fifth with a tuft of 
hair on each side at the base. Middle and posterior feet with the 
femora rather stout ; the tibiae very spiny all round, their spurs stout ; 
the tarsi densely spiny above, and, except the fifth joint, spiny below ; 
the spines below arranged somewhat in two series, the first joint longer 
than the rest combined, second about one- third the length of the

first, third three-fourths the length of the seccmd, fourth rather more 
than half the length of the third, fifth not quite so long as the third. 
Claws curved, acute, grooved below; paronychia bilaciniate; the 
outer lacinia slender, pointed, not so long as the claw ; the inner 
lancet-shaped, much broader than and nearly as long as the outer, 
very hairy ; pulvillus jointed, broad, not so long as the claws. * Ab- 
domen rather short, not robust. 

This interesting genus, as remarked above, appears to be almost 
confined to the eastern slopes of the Andes and to the great branch 
of that mountain-range which runs along the northern parts of South 
America. Nearly all the specimens of the five or six species belong- 
ing to it existing in British collections were sent home by Mr. Bridges 
from the eastern parts of Bolivia, and by Mr. Dyson from Caraccas. 
The peculiar sexual scales on the disc of the anterior wings of the 
males resemble those of the males of most species of this family in 
being long, tapering to a delicate hair-like point, at the end of 
which is a little plumelet. 

In form this genus resembles the P. Actorion of Linnaeus, which 
is the type of the genus Napho of Boisduval, but that insect belongs 
to the preceding family of Morphidce .

Anterior wings, above chocolate-brown at the base, darker at the 
apex and along the outer margin ; between the cell and the apex is 
a transverse band composed of three fulvous spots, the first of which 
is divided by the subcostal nervure ; midway between the cell and the 
outer margin a curved spot of the same colour, divided by the first 
median nervule, and a' rounded spot of the same colour near the anal 
angle. Posterior wings with the anal angle considerably produced 
into a tail, entirely chocolate-brown. Below, the anterior wings are 
fuscous, the base rather paler, the apex ashy ; the subapical spots 
nearly white, the others as above ; the posterior wings clouded and 
freckled with ashy- grey and fuscous, having a slight silvery reflec- 
tion ; a transverse band, commencing on the costa, crosses the middle 
of the cell, and terminates before it reaches the inner margin ; a 
second similar band commences on the costa, and running along the 
lower disco-cellular nervule, terminates at the tail. 

Head, thorax and abdomen fuscous above, the two latter greyish 
below ; antennae fuscous ; palpi fuscous above, pale below. 

This insect was taken by Mr. Dyson in the mountains of Caraccas, 
where it seems to be rather rare. 

2. Description of a new genus of Notodontid^:. 

By E. Doubleday, F.Z.S. 

Genus Hyl^eora. 

Head small, densely clothed with long hair-like scales, those at the 
base of the antennae very long, forming two tufts, which meet over 
the vertex. Eyes round, prominent. Maxillae slender, short, scarcely

so long as the thorax. Labial palpi short, the first and second joints 
densely scaly, the scales hair-like, the third joint clothed with short 
scales : first joint much curved, broadest at the apex; second joint 
one-half longer than the first, subcylindric, stoutest in the middle, 
truncate at the apex ; third joint small, oval, about one-third the 
length of the second joint. Antennae of the male elongate, densely 
bipectinate, each pectination beautifully fringed with hairs : of the 
female long, setaceous, the inside set with short stiff hairs. 

Thorax stout, crested, the crest much highest in front. Anterior 
wings elongate, the anterior margin but little curved until near the 
apex ; outer margin rather more than half the length of the anterior, 
slightly dentate ; inner margin nearly straight, rather longer than 
the outer. Costal nervure extending about three-fourths the length 
of the costa. First subcostal nervule thrown off beyond the middle 
of the cell, terminating not far from the extremity of the costal ner- 
vure ; second subcostal nervure thrown off shortly before the end of 
the cell, curved so as to cross the subcostal nervure at some distance 
beyond the end of the cell, terminating on the outer margin midway 
between the fifth subcostal and the first discoidal nervule; third 
subcostal nervule arising rather nearer to the end of the cell than to 
the apex of the wing ; the fourth nearer to the third than to the apex, 
this nervule terminating at the apex. First discoidal nervule appear- 
ing at first sight to be a continuation of the subcostal nervure, the 
upper disco- cellular nervule being wanting. Lower about the same 
length as the middle disco-cellular nervule, united to the third me- 
dian nervule shortly after its origin. Posterior wings with the ante- 
rior margin nearly straight, longer than the outer, which is rounded. 
Inner margin about two-thirds the length of the outer. Cell closed. 
Upper and lower disco-cellular nervule of about equal length. Dis- 
coidal nervure very slender ; the basal portion, as far as the end of the 
cell, atrophied. Legs with the femora and tibise densely hairy. The 
anterior tibiae with a broad spur, nearly as long as the tibia itself, 
composed of a flat, slightly curved lancet-shaped lamina, fringed an- 
teriorly. Tibiae of the middle pair with two unequal spines at the 
apex, those of the third pair with two before the apex, two at the 
apex. Tarsi scaly, the first joint much the longest; claws small, 
curved ; paronychia broad, very hairy, especially at the apex, shorter 
than the claw ; pulvillus jointed, the second joint very broad. Ab- 
domen clothed with long hairs, elongate, longer in the male than in 
the female. 

Larva stout, tapering towards the tail, the back flat, with a cre- 
nated ridge on each side.

I have not thought it necessary to enter into a detailed specific 
character of this insect, as the accompanying figure will give a far 
better idea of the species than the longest description. The noc-

turnal Lepidoptera are often almost impossible to describe, and it is 
only by the most accurate figures, or by comparison of specimens, 
that we can arrive at the determination of species. 

I am indebted to Mr. Alfred Lambert of Sydney for the speci- 
mens figured and for the drawing of the larva. The following note 
accompanies the specimen : — 

“The larva is figured in drawing No. 2. When I first found it I 
concluded that it was a Cerura, as in its habits it resembles the larva 
of that genus. It forms a strong cocoon, which is slightly attached 
to the trunk of the tree just below the surface of the ground. In 
form this cocoon is much like that of our common Saturnia , only 
exteriorly it is covered with points of sticks, grass, &c. The larva feeds 
on the Eucalypti , is found in January ; the imago appears in July.” 

From this it will be seen that it is a winter insect.

MISCELLANEOUS. 

Descriptions of Owls presumed to be undescribed. By John Cassin, 

Ephialtes sagittatus , nobis. Adult r Entire plumage above rufous 
brown, inclining to chestnut ; plumage of the head with small pale 
spots encircled with black, bordering the shafts of the feathers, and 
near the tips assuming a hastate or sagittate form. 

Plumage of the back with every feather having about three to five 
spots of the same description, the arrow-headed shape and black 
border distinct and well-defined, some of the spots nearly white ; 
every feather also with very fine transverse lines, and minutely dotted 
or freckled with black. 

Wing-coverts with pale, nearly white, sagittate spots encircled 
with black. Internal coverts of the wings pale fawn yellow, more 
or less spotted with black, and with their tips broadly terminated 
with black, which forms a conspicuous bar on the inferior surface of 
the wing. Outer edge of scapulars nearly white with black spots. 
External webs of primaries with alternate bands of pale and darker 
rufous brown ; internal webs much darker, with nearly black bands 
alternating with others slightly paler, which (the paler) are mottled 
with black towards the extremities of the quills. Exposed ends of 
the secondaries rufous brown, with large pale spots on the shafts, 
approaching the sagittate form, with their black borders extending 
into transverse narrow bands. First primary shortest, fifth and 
sixth longest. 

Feathers encircling the eyes, and the long bristle- like feathers at 
the base of the bill dark chestnut-brown, the latter freckled with 
black ; between the eye and the cavity of the ear whitish, with 
transverse lines, and broadly tipped with deep rufous brown. 
Feathers of the ruff white at their bases, with narrow transverse 
lines of deep rufous, but presenting a broad subterminal band of pure 
white, every feather terminated with a semicircular or lunular band 
of bright rufous brown. 

Front and superciliary region white, the feathers of the former 
with their shafts and with some minute marks of very dark brown ; 
superciliary feathers with well-defined tips of nearly black. Shorter 
(or anterior) feathers of the ear-like tufts white, with minute trans- 
verse lines and freckles of rufous brown ; longer feathers of the tufts 
brown on their external and white on their internal webs, trans- 
versely lined and tipped with darker brown. 

General colour of the under surface of the body very pale rufous 
and sordid yellowish white, on the breast with every feather having 
about five to seven very narrow transverse bands more or less di-
