Figure 69. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (0) and of female {D) of Chrysobothris calif ornica. 



Head bronzy cupreous, witb two small, elongate, smooth callosities on front, 

 and a broad, smooth, longitudinal carina on occiput; front nearly flat; surface 

 coarsely, deeply, confluently punctate, sparsely clothed with long, semierect, incon- 

 spicuous hairs ; clypeus broadly, deeply, angularly emarginate in front, arcuateiy 

 rounded on each side. Antenna uniformly bronzy, slightly narrowed to apex ; 

 intermediate segments subtriangular, as long as wide, broadly rounded at outer 

 margins ; third segment nearly as long as following two segments united. 



Pronotum two-thirds wider than long, slightly narrower at apex than at base, 

 widest along middle ; sides slightly sinuate and nearly parallel at middle, arcuateiy 

 converging posteriorly and anteriorly ; anterior margin broadly, arcuateiy 

 emarginate, with a broad, vague, median lobe ; base broadly, arcuateiy emarginate 

 on each side, median lobe strongly produced, and broadly rounded ; disk rather 

 strongly convex, uneven, narrowly depressed on each side along lateral margin, 

 with a broad, longitudinal, densely punctured, median depression, limited on each 

 side on apical two-thirds by a broad, irregular, elevated, smooth callosity, and on 

 each side midway between this callosity and lateral margin two small, irregular, 

 smooth callosities ; surface coarsely, deeply, irregularly, confluently punctate 

 between smooth callosities. 



Elytra distinctly wider than pronotum, nearly twice as long as wide : sides 

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

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

 depressions broad, very deep; humeral depressions broad, moderately deep; 

 surface glabrous, uneven, finely, densely punctate between costae and smooth, 

 elevated spaces, which are more or less connected to costae. Each elytron with 

 three more or less distinct, longitudinal costae; first distinct, slightly sinuate, 

 extending along sutural margin from apex to base ; second straight, rather 

 distinct, broadly interrupted by punctured spaces ; third irregular, barely indi- 

 cated, and broadly interrupted. 



Abdomen beneath coarsely, rather densely, irregularly fossulate-punctate, 

 sparsely clothed with short, recumbent, white hairs, and each sternite with an 

 obsolete, smooth, lateral callosity on each side ; last visible sternite deeply, semi- 

 circularly emarginate at apex, without a submarginal ridge, lateral margins 

 slightly serrate ; eighth tergite deeply, densely, coarsely punctate, densely granu- 

 lose, but not longitudinally carinate, upper margin angularly emarginate at apex. 

 Prosternum coarsely, confluently punctate, densely clothed with long, erect, white 

 hairs, narrowly, transversely depressed along anterior margin, without a median 

 lobe in front. Anterior femur with a broad, obtuse tooth, which is slightly 

 dentate on outer margin. Anterior and middle tibiae strongly arcuate, the former 

 with a long, sinuate dilation, but not constricted behind dilation ; posterior tibia 

 straight. 



Length 17 mm., width 7.5 mm.
