Figure 78. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (0) and of female (D) of Chrysobothris sylvania. 



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

 piceous on the elevated, smooth spaces, bronzy green in the densely punctured 

 areas ; beneath bright green, more strongly shining than above, with the smooth 

 callosites at sides of abdominal sternites violaceous. 



Head yellowish cupreous in front, becoming darker on occiput, with two small, 

 smooth callosities on front, and a distinct, smooth, longitudinal carina on occi- 

 put; front nearly flat; surface coarsely, deeply, confluently punctate, rather 

 densely clothed with long, erect, fine, brownish hairs; clypeus broadly, deeply, 

 angularly emarginate in front, arcuately rounded on each side. Antenna uni- 

 formly bright green, slightly narrowed to apex; intermediate segments sub- 

 triangular, slightly wider than long, broadly rounded at outer margins ; third 

 segment about one-fourth longer than fourth. 



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

 along middle ; sides parallel and sinuate at middle, arcuately converging to apex 

 and base, more strongly posteriorly; anterior margin broadly, arcuately emar- 

 ginate, without a distinct median lobe ; base subtruncate on each side, median 

 lobe slightly produced, broadly rounded in front of scutellum ; disk slightly con- 

 vex, very uneven, with a broad, longitudinal, median sulcus, limited at each 

 side on apical half by a broad, elevated, smooth space, a small, smooth callosity 

 on each side at elytral lobe, and a broad median depression on each side near 

 lateral margin ; surface coarsely, deeply, confluently punctate between the smooth 

 callosities.
