A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 



63 



Very little variation was observed in the small series of specimens 

 examined, except in size, which ranges from 8.5 to 11 mm. in length. 



Chrysobothris bacchari can scarcely be separated from beyeri 

 Schaeffer, but since Los Gatos is the type locality for bacchari, the 

 name is retained for the specimens from California. The specimens 

 of bacchari examined average smaller in size than those of beyeri, are 

 more uniformly bronzy brown, with only a vague cupreous reflection, 

 and the pubescence on the elytra is only slightly indicated toward the 

 apices. The male genitalia are similar in the two species, but in 

 the male of beyeri the dilation on the anterior tibia is nearly one- 

 third the length of the tibia, whereas in bacchari it is not one-fourth 

 as long as the tibia. 



Van Dyke (1923) includes specimens from Arizona, which are 

 wi Schaeffer, in his original description of bacchari.

Figure 18. — Anterior tibia of male (A), clypeus (B), and last visible abdominal 

 sternite of male (C) and of female (D) of Chrysobothris purpurata. 



Female.— Rather broadly elongate, moderately depressed above, rather strongly 

 shining, uniformly purplish brown, with a faint cupreous tinge in certain 

 lights ; beneath similar in color to above. 



Head uniformly purplish red, with two small, smooth callosities on front, 

 and a narrow, longitudinal carina on occiput ; front nearly flat ; surface coarsely, 

 confidently punctate, sparsely clothed with moderately long, recumbent, white 

 hairs, intervals vaguely granulose ; clypeus broadly, subtriangularly emarginate 

 in front, broadly rounded on each side. Antenna bronzy cupreous, slightly
