Sometimes, prothorax is paler brown with a dark brown stripe laterally. Elytra dark or pale brown dorsally, with more or less small grey spot mottling. Sides of head, prothorax and elytra, and the ventrum are greyish or whitish. Elytral margins are with some brown spots. Eyes lateral, and the forehead is broad.
