Clypeai projection from above almost triangular, below 
it is black, and a spine each side on margin of clypeus; 
enclosure moderately large, rather finely longitudinally 
striate ; pygidium about two and one-lialf times as long as 
wide at base, much narrowed toward the tip, dark fringe 
each side. Front and mid femora dark on base, hind 
femur and tibia dark on tip, hind tarsus very dark, ex- 
cept a narrow line above on basitarsus. Wings with dark 
front part, most prominent beyond the yellowish stigma. 
Body rather finely punctate, hair on head and thorax 
moderately long. 
Male very similar in coloration, but the bands on ab- 
domen are less broad on sides, and the spots on first seg- 
ment are smaller. The clypeai truncation has three teeth, 
the hair-lobes about as broad as the truncation; face, 
from side, is rather short-haired; enclosure longitudinally 
striate as in the female ; pygidium broadly truncate at tip, 
its base scarcely more narrow, coarsely punctate, one and 
a half times as long as broad. 
Length of $ 12 mm., of <$ 10 mm. 
Type of Provancher was simply California, a male. I 
have identified as it a male from San Mateo Co., Calif., 20 
June, and a female from Big Flat, Coffee, Trinity Co., 
Calif. The description of Provancher would fit the male 
of C. varians just as well. 
This species is close to C. varians, but the clypeai proc- 
ess is much more elevated, and there is no mark on the 
propodeum. 
In male the face has shorter hair than varians, there 
are teeth on the truncation of clypeus, and the pygidium 
is scarcely more narrow at base.
