Figure 22. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (C) and of female (D) of Clirijsobotliris prosopidis. 



Male. — Moderately elongate, rather strongly convex above, moderately shining, 

 reddish brown, with a faint bronzy tinge, the costae on the elytra bluish black ; 

 beneath purplish brown, greenish black along posterior margins of sternites, and 

 more strongly shining than above. 



Head reddish cupreous, with two small, smooth callosities on front, and a 

 narrow, longitudinal carina on occiput ; front feebly convex ; surface rather 

 densely, coarsely, shallowly punctate, sparsely clothed with long, recumbent, 

 whitish hairs, intervals finely, densely granulose ; clypeus deeply, semicircularly 

 emarginate in front, arcuately rounded on each side. Antenna uniformly brown- 

 ish cupreous, feebly narrowed to apex ; intermediate segments compact, slightly 

 wider than long, broadly rounded at outer margins ; third segment as long as 

 the following two segments united. 



Pronotum nearly twice as wide as long, narrower at base than at apex, 

 widest near apex ; sides arcuately converging at apical angles, more strongly, 

 arcuately converging from near apical angles to posterior angles ; anterior mar- 

 gin strongly sinuate, with a broadly rounded median lobe; base deeply, ar- 

 cuately emarginate on each side, the median lobe feebly produced, and truncate 

 in front of scutellum ; disk moderately convex, without callosities or a median 

 depression ; surface densely, rather deeply, uniformly punctate, transversely 

 rugose and more finely punctate at sides, intervals finely, densely granulose. 



Elytra slightly wider than pronotum, nearly twice as long as wide, widest 

 behind middle; sides feebly diverging from humeral angles to behind middle, 

 then arcuately converging to tips, which are separately broadly rounded ; lateral 

 margins coarsely serrate ; basal depressions broad and rather deep ; humeral 

 depressions broad and shallow; surface glabrous, densely, finely, uniformly 

 punctate between costae, more or less rugose toward base, intervals densely, 

 finely granulose. Each elytron with four more or less distinct, smooth, longi- 

 tudinal costae; first straight, extending from apex to near base; second and
