strongly punctate, feeblest on head, strongest at base of elytra; 
sterna moderately densely and strongly, abdominal segments 
minutely punctate. 
Head small, closely joined to prothorax, strongly transverse;

at apex. Elytra more than twice as long as head and prothorax 
combined, base truncate, shoulders scarcely rounded, sides 
parallel to near apex; the base with a depression on each side
