Figure 106. — Clypeus (A), and last visible abdominal sternite of male (B) and of 

 female (C) of Chrysobothris alleni. 



Female. — Rather broadly elongate, strongly convex above, moderately shining, 

 bright green, with a faint golden tinge; beneath bluish green. 



Head bronzy green on vertex and occiput, becoming bluish green toward 

 clypeus, with an obscure longitudinal carina on occiput, terminating anteriorly in 

 a small, shallow depression on vertex; front slightly convex; surface coarsely, 

 rather densely, shallowly, irregularly punctate on vertex and occiput, coarsely, 

 deeply, irregularly ocellate-punctate on front, sparsely clothed behind clypeus 

 with short, inconspicuous hairs, intervals finely alutaceous; clypeus broadly, 

 shallowly, arcuately emarginate in front, slightly rounded on each side. Antenna 

 bronzy green basally, cupreous apically, nearly equal in width to apex ; intermedi- 

 ate segments not compact, strongly triangular, as long as wide, acutely angu- 

 lated at outer margins ; third segment elongate-triangular, as long as following 

 three segments united. 



Pronotum twice as wide as long, narrower at apex than at base, widest just 

 behind middle; sides obtusely rounded just behind middle, arcuately converg- 

 ing anteriorly and posteriorly ; anterior margin slightly, arcuately emarginate, 

 with a broadly rounded median lobe; base truncate on each side, median lobe 

 strongly produced and broadly rounded ; disk strongly convex, with a broad, 

 indistinct, median depression, but without smooth callosities ; surface glabrous, 

 densely, deeply, rugosely punctate, intervals faintly alutaceous. 



Elytra at base subequal in width to pronotum at middle, about one and 

 one-half times as long as wide, widest at apical third ; sides slightly diverging 

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

 are separately broadly rounded, but not extending to tip of abdomen ; lateral 

 margins slightly serrate; basal depressions very deep, but without distinct 

 humeral depressions ; surface glabrous, slightly uneven, coarsely, deeply, irregu- 

 larly punctate, more or less rugose basally, intervals finely, densely granulose. 



Abdomen beneath glabrous, coarsely, sparsely, irregularly punctate, more 

 densely punctate on apical sternites, without lateral callosities, intervals finely, 

 densely granulose : last visible sternite broadly, obtusely rounded at apex, 

 without a submarginal ridge, lateral margins not serrate ; eighth tergite densely,
