Figure 33. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

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



Male. — Broadly elongate, rather strongly depressed above ; pronotum faintly 

 reddish cupreous, subopaque ; elytra piceous, with a slightly bronzy-green 

 tinge, and moderately shining; beneath purplish cupreous, with a faint green- 

 ish tinge, more strongly shining than above. 



Head brownish cupreous, becoming bronzy green toward clypeus, with a 

 narrow, smooth, longitudinal carina on occiput, the carina bifurcate on vertex ; 

 front slightly convex ; surface coarsely, deeply, confluently ocellate-punctate, 

 densely clothed with long, recumbent, white hairs, intervals densely granulose ; 

 clypeus broadly, shallowly, arcuately emarginate in front, arcuately rounded 

 on each side. Antenna piceous, with a faint bronzy tinge, nearly equal in 

 width to apex; intermediate segments nearly twice as wide as long, rather 

 compact, truncate at outer margins ; third segment slightly shorter than fol- 

 lowing two segments united. 



Pronotum three-fourths wider than long, subequal in width at base and apex, 

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

 converging toward apical angle's, more strongly, obliquely converging toward 

 posterior angles ; anterior margin rather strongly sinuate, with a broadly 

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

 lobe strongly produced and broadly rounded; disk moderately convex, without 

 distinct depressions or callosities; surface coarsely, deeply, sparsely, irregu- 

 larly punctate at middle, coarsely, confluently punctate at sides, intervals 

 densely granulose.
