Figure 42. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (C) and of female (D) of Clirysototliris axillaris. 



Female. — Broadly elongate, moderately convex above, subopaque, black, with 

 a slight bronzy-brown tinge, basal depression and a large humeral space on each 

 elytron brigbt reddish cupreous; beneath bluish black, more strongly shining 

 than above, and anterior tibiae more or less reddish cupreous. 



Head black, with two small, round callosities on front, and a broad, sniootb, 

 longitudinal carina on occiput, carina bifurcate on vertex ; front nearly flat ; 

 surface coarsely, densely, uniformly fossulate-punctate, sparsely clothed with 

 short, recumbent, whitish hairs, intervals densely granulose ; clypeus broadly, 

 deeply, arcuately emarginate in front, strong] y, arcuately rounded on each side. 

 Antenna piceous, gradually narrowed to apex ; intermediate segments subtri- 

 angular, rather compact, slightly wider than long, broadly rounded at outer 

 margins ; third segment nearly as long as following two segments united. 



Pronotum twice as wide as long, subequal in width at base and apex, widest 

 near apex ; sides strongly, arcuately rounded at apex, arcuately converging 

 from near apex to base ; anterior margin slightly sinuate, with a vague, broadly 

 rounded, median lobe ; base angularly emarginate on each side, median lobe 

 slightly produced, and subtruneate in front of scutellum ; disk moderately con- 

 vex, without depressions or callosities ; surface finely, rather sparsely, uniformly 

 punctate at middle, more densely punctate and slightly rugose at sides, intervals 

 finely granulose. 



Elytra slightly wider than pronotum, nearly twice as long as wide; sides 

 nearly parallel from humeral angles to apical third, then arcuately converging 

 to tips, which are separately broadly rounded ; lateral margins coarsely serrate ; 

 basal depressions broad and deep; humeral depressions obsolete; surface gla- 

 brous, densely, uniformly, finely punctate, more or less scabrous toward base 

 and at sides, intervals densely granulose, witbout discal foveae, but with first 

 costa vaguely indicated on apical half of each elytron.
