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



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

 uniformly piceous, with a vague purplish reflection ; beneath purplish cupreous, 

 with a distinct bronzy tinge (legs more or less greenish), and more strongly 

 shining than above. 



Head bronzy green in front, piceous on Occiput, with a smooth longitudinal 

 carina on occiput, and two small callosities on front ; front nearly flat ; surface 

 coarsely, densely punctate, sparsely clothed with long, erect, inconspicuous hairs, 

 the intervals densely, finely granulose ; clypeus broadly, rather deeply, angu- 

 larly emarginate in front, arcuately rounded on each side. Antenna bronzy 

 green, gradually narrowed to apex ; intermediate segments moderately com- 

 pact, slightly wider than long, broadly rounded at outer margins; third seg- 

 ment nearly as long as the following two segments united. 



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

 widest along middle ; sides parallel and slightly sinuate along middle, arcuately 

 converging near base and apex; anterior margin sightly sinuate, with an 

 obsolete, broadly rounded median lobe ; base shallowly, arcuately emarginate 

 on each side, median lobe slightly produced, and subtruncate in front of 

 scutellum ; disk moderately convex, slightly uneven, with a broad, shallow,
