Figure 43. — Anterior tibia of male (A), clypeus (B), arid last visible abdominal 



sternite 



of male (<7) and of female (D) of Chrysobotliris acaciae. 



Male. — Broadly elongate, moderately convex above, subopaque, bronzy brown, 

 with a faint greenish tinge, anterior median part of pronotum and humeral 

 spaces on each elytron bright coppery red ; beneath piceons, with a distinct 

 bluish and greenish tinge, 'and prosternum slightly cupreous. 



Head bronzy green in front, becoming coppery reel on vertex and occiput, with 

 two smooth callosities on front, a vague, longitudinal carina on occiput, and an 

 obscure chevron on vertex ; front flat ; surface coarsely, densely punctate, 

 rugose behind clypeus, densely clothed with long, recumbent, white hairs, inter- 

 vals densely granulose ; clypeus deeply, arcuately emarginate in front, arcuately 

 rounded on each side. Antenna uniformly reddish cupreous, slightly narrowed 

 to apex ; intermediate segments compact, wider than long, subtruncate at outer 

 margins ; third segment slightly longer than fourth. 



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

 widest at apical fourth ; sides strongly, arcuately converging toward apical 

 angles, strongly, obliquely converging from apical fourth to posterior angles : 

 anterior margin slightly sinuate, with a broadly rounded median lobe ; base 

 deeply, arcuately emarginate on each side, median lobe rather strongly produced 

 and broadly rounded ; disk moderately convex, without depressions or callo- 

 sities : surface sparsely, coarsely punctate at middle, more densely punctate and 

 rugose toward sides, with a vague, smooth, median line extending from scutel- 

 lum to middle, the intervals fineiy, densely granulose. 



Elytra distinctly wider than pronotum. widest behind middle ; sides parallel 

 anteriorly, broadly dilated behind middle, then arcuately converging to tips, 

 which are separately broadly rounded : lateral margins finely serrate posteriorly : 

 basal depressions broad and deep: humeral depressions broad and moderately 

 deep: surface glabrous, densely, finely punctate, the intervals densely granulose, 

 and each elytron with four indistinct, longitudinal costae. 



Abdomen beneath densely, finely punctate, densely clothed with long, recum- 

 bent, white hairs, smooth along anterior and posterior margins of sternites, with- 

 out lateral callosities, intervals obsoletely granulose ; last visible sternite broadly, 

 deeply, arcuately emarginate at apex, with a slightly elevated, serrate, sub- 

 marginal ridge, lateral margins finely serrate ; eighth tergite feebly notched at 

 apex, densely granulose, densely, coarsely punctate, but not longitudinally cari- 

 nate. Prosternum flat, coarsely, confluently punctate, transversely rugose an-
