Form: Length, 7 mm. Vertex slightly longer on middle than next 

 the eye, over twice as wide as long. Pronotum twice as wide as long, 

 anterior margin strongly convex, posterior margin distinctly concave, 

 short lateral margins rounding into the humeral margins, disc trans- 

 versely wrinkled. Elytra long, greatly exceeding abdomen. 



Color: General color brownish. Vertex, pronotum, and scutellum with 

 a greenish tinge. Vertex with a broad transverse black band on the disc. 

 Pronotum marked with brown, the median line and anterior margin paler. 

 Scutellum with triangular spots in basal angles, a median line with a 

 small spot on either side, brown. Elytra brown with the nervures lighter, 

 giving them a striped appearance. Face with ten pale arcs and two 

 brown spots at base of clypeus. 



External genitalia: Female, last ventral segment over twice as long 

 as the preceding, strongly narrowed posteriorly, lateral angles acute, be- 

 tween them the posterior margin being broadly and deeply cleft, the cleft 

 with a small blunt tooth; pygofers rather broad, nearly equalling ovi- 

 positor, spined on distal half. Male, valve about twice as long as preced- 

 ing segment, broad, margins concave on either side of the rounded apex;
