 parallel, arcuately narrowing at apical third with the 

 margin rather coarsely serrate, apex obtuse, disc con- 

 vex without costal or fove« except the usual basal de- 

 pression, the surface not closely submuricately punctured, 

 the intervals alutaceous. Body beneath coarsely and 

 closely punctate with few hairs, the abdomen smoother 

 and with more cupreous luster at the sides. Last ventral 

 with an entire lateral margin and a well defined supple- 

 mentary margin serrate near the apex. Length, .27 inch:

Male. — Anterior femur with a broad triangular tooth 

 serrate on its distal edge, the tibia slightly arcuate. Last 

 ventral with an acute angle each side, the interval be- 

 tween them bisinuate. 



This species belongs with those in which the last ven- 

 tral segment has an entire edge without serrulation and 

 where the elytra have neither discal foveas nor costa?. In 

 a general way it resembles analis.
