Figuee 27. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (C) and of female (D) of Chrysobothris octocola. 



Female. — Moderately elongate, rather strongly depressed above, moderately 

 shining, olivaceous brown, with faint purplish and greenish reflections in differ- 

 ent lights, and each elytron with four yellowish-cupreous f oveae ; beneath 

 brownish cupreous, more strongly shining than above, the tarsi, margins of 

 sternites, and lateral callosities on sternites greenish or bluish black. 



Head bronzy brown, green along anterior margin of clypeus, with a trans- 

 verse, irregular ridge behind clypeus, a broadly angulated chevron on front, 

 and a narrow, smooth, longitudinal carina on occiput; front slightly convex; 

 surface coarsely, deeply, confluently punctate, sparsely clothed with long, semi- 

 erect, white hairs; clypeus broadly, rather deeply, arcuately emarginate in front, 

 broadly rounded on each side. Antenna uniformly bronzy brown, gradually nar- 

 rowed to apex ; intermediate segments as long as wide, broadly rounded at outer 

 margins ; third segment subequal in length to following two segments united. 



Pronotum nearly twice as wide as long, slightly wider at base than at apex, 

 widest at apical third; sides arcuately converging toward apex and base; ante- 

 rior margin broadly, arcuately emarginate, with an indistinct, broadly rounded, 

 median lobe ; base vaguely, arcuately emarginate on each side, the median lobe 

 rather strongly produced and broadly rounded ; disk uniformly convex, without 

 depressions or callosities ; surface coarsely, densely, uniformly punctate at 

 middle, confluently, rugosely punctate at sides. 



Elytra at base slightly wider than pronotum at apical third, 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
