sides are more or less parallel, but in a few specimens examined the 

 pronotum was widest near the apical fourth and the sides more 

 strongly converging posteriorly. In the large specimens the pro- 

 notum is vaguely depressed at the middle and the longitudinal costae 

 on the elytra are vaguely indicated, but in the smaller specimens these 

 depressions and costae are entirely obliterated. The lateral margins 

 of the elytra are distinctly serrate posteriorly in some specimens, 

 whereas in others the margins are so indistinctly serrate as to be 

 considered as entire. In most females examined the tips of the last 

 visible sternite and eighth tergite are slightly emarginate, but occa- 

 sionally specimens are found in which they could not be considered 

 as being emarginate. The specimens examined from Oregon are 

 slightly broader, and the hairs are slightly longer and denser than 

 in the specimens from California. Van Dyke (1916) records collect- 

 ing a good series of adults under the same conditions and in the same 

 locality in the King River region of the southern Sierras, which 

 varied in color from brilliant bluish green through bronzy green 

 to cupreous. In the middle Sierras and northward they are more 

 apt to be bluish green and the color more constant. The length is 

 from 5 to 9.5 mm.

Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (C) of Chrysobothris boharti. 



Male. — Moderately elongate, more or less depressed above, rather strongly 

 shining, uniformly bronzy green; beneath bottle green, with a slight bronzy 

 tinge, and more strongly shining than above. 



Head uniformly bronzy green, with a vague chevron on the front and a 

 vague, longitudinal carina on occiput ; front slightly convex ; surface densely, 

 coarsely ocellate-punctate, sparsely clothed with rather short, recumbent hairs, 

 the intervals finely granulose ; clypeus broadly, angularly emarginate in front, 

 broadly rounded on each side. Antenna piceous, more or less greenish toward 

 base, gradually narrowed to apex ; intermediate segments compact, wider than 

 long, broadly rounded at outer margins; third segment slightly longer than 

 fourth.
