Elytra minutely and sparsely punctulate, rather convex, as 
wide across the shoulders as the prothorax, and nearly one- 
third wider across the middle; the length of the suture is one- 
fifth greater than the width of the prothorax, the sides evenly 
arcuate; the sutural interval is slightly dilated behind the 
middle, the lines deep, discal ones half the length of the 
elytra. Addomen as long as the elytra, border strong, basal 
caring including one-fifth of the segmental width, very short 
on the first and second segments and only indicated on the 
third. Legs moderately strong. Sexual differences consist 
of a lateral swelling of the posterior edge of the third ventral 
segment, a transverse median depression of the base of the 
fourth, and a transverse median depression before the middle 
of the fifth; the last ventral is lozenge-shaped, longitudinally 
carinate in the middle and punctured.
