Figuee 29. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (O) and of female (D) of Chrysobothris cuprascens. 



Male. — Moderately elongate, rather strongly depressed above, moderately shin- 

 ing, brownish cupreous, the pronotum slightly more reddish cupreous ; beneath 

 brownish cupreous, with a vague bronzy reflection, and more strongly shining 

 than above. 



Head bright bronzy green, becoming reddish cupreous on vertex and occiput, 

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

 surface coarsely, rather densely, deeply punctate, slightly, transversely rugose 

 behind clypeus, sparsely clothed with moderately long, erect, fine, white hairs, 

 intervals densely granulose; clypeus angularly notched at middle, on each side of 

 emargination obtusely toothed, then transversely truncate externally. Antenna 

 bronzy green, more or less piceous toward outer margins of segments, nearly 

 equal in width to apex; intermediate segments compact, twice as wide as long, 

 broadly rounded at outer margins ; third segment subequal in length to following 

 two segments united. 



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

 along middle ; sides nearly parallel and strongly sinuate along middle, obliquely 

 converging posteriorly and anteriorly ; anterior margin slightly sinuate, with 

 an indistinct median lobe ; base strongly, arcuately emarginate on each side, 

 the median lobe strongly produced and broadly rounded; disk slightly uneven, 

 with a vague, longitudinal, median depression, and with four more or less 

 distinct, small, irregular, smooth spots arranged transversely in front of 

 middle ; surface coarsely, deeply, but not very densely, punctate at middle, 

 confiuently punctate at sides, the intervals densely granulose. 



Elytra at base wider than pronotum at middle, twice as long as wide ; sides 

 nearly parallel from humeral angles to apical third, then arcuately converg-
