Figure 58. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (C) and of female (D) of Cftrysoboihris exesa. 



Female. — Moderately elongate, convex and rather strongly shining above, 

 piceous, with a faint purplish reflection on the smooth spaces, brownish cupreous 

 in the depressed, punctured areas ; beneath brownish cupreous, with purplish and 

 greenish reflections in different lights, and more strongly shining than above. 



Head uniformly brownish cupreous, with a broad, smooth, longitudinal carina 

 extending from occiput to middle of front, the carina bifurcate on vertex, and 

 connected on each side anteriorly to a broad, irregular, smooth space ; front 

 uneven ; surface coarsely, irregularly, confhiently punctate, somewhat rugose 

 behind clypeus, sparsely clothed with long, recumbent, white hairs, intervals 

 densely granulose ; clypeus broadly, deeply, angularly emarginate in front, broadly 

 rounded on each side. Antenna uniformly piceous, with a faint purplish tinge, 

 slightly narrowed to apex ; intermediate segments compact, distinctly wider than 

 long, broadly rounded at outer margins ; third segment nearly as long as follow- 

 ing two segments united. 



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

 widest near apex ; sides strongly converging at apex, obliquely converging 

 (slightly sinuate at middle) from near apex to base; anterior margin rather 

 strongly, arcuately emarginate, with a broadly rounded median lobe; base 

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

 and broadly truncate in front of scutellum; disk moderately convex, uneven,, 

 with a broad, shallow, longitudinal, median depression, four small, more or 

 less distinct, irregular, smooth callosities arranged transversely in front of 

 middle, and on each side at base, midway between middle and lateral margin, 

 an irregular, smooth callosity ; surface coarsely, irregularly ocellate-punctate 

 between the smooth callosities. 



Elytra slightly wider than pronotum, twice as long as wide ; sides nearly 

 parallel from humeral angles to apical third, then arcuately converging to tips, 

 which are conjointly broadly rounded ; lateral margins coarsely serrate ; basal 

 depressions broad, very deep ; humeral depressions broad and shallow ; disk 

 rather strongly convex, uneven; surface glabrous, densely, deeply, confluentiy 

 punctate between costae and smooth elevated spaces. Each elytron with four 

 more or less distinct longitudinal costae; first strongly elevated from apex to 

 basal third, irregularly interrupted on basal third ; second and third interrupted 

 by broadly expanded and irregular, smooth, elevated spaces ; fourth barely indi- 

 cated, following outline of lateral margin, and with two irregular, transverse, 

 densely punctured, discal foveae, the first between first and third costae in 

 front of middle, and the second between first and third costae on apical third. 



Abdomen beneath sparsely, coarsely fossulate-punctate, sparsely clothed with
