M. Valctta is very nearly allied to M. Marcella $, but 
differs from the white-banded form of the female of that 
species in having the spots near anal angle of frontwings 
more distinctly separated ; the apex of hindwings ochreous 
and the white spots more distinct, below it differs in the 
arrangement of the bands, which, however, in their general 
aspect, are very similar to those of M. Marcella.
