ochraceous liair-baiuls ; first two sogincnts transversely 

 snleate ; last ventral sej^meiit smooth ; ventral si-gments 

 not stroiif^ly bearded laterally. 



In llobertson's talde runs to C. eulophi, Rob., but is 

 distiiij^'uislied from that by the dense strong punctures of first 

 abdominal segment, dark posterior tarsi, &e. 



This is smaller than the type male from Washington State.

Similar to C. salicicola, CUll. (with just the same abdo- 

 minal pubescenee, with broad white bands, and much hair at 

 base of second segment ; the same wliite hair on pleura and 

 metathorox, and very light ochreous — exaetly the ^ame 

 tint — on mesotiiorax and top of head), but differing thus : — 

 clypeus with much smaller and closer j)nnetures (in salicicola 

 they are very large and sparse, except at extreme sides) ; 

 malar space shorter, being about twice a> broad as Ion" ; 

 first abdominal segment, except the depressed hind margin, 

 dull, with small well-separated punctures (very shiny in 

 sulicirola) ; black (bare) band on abdominal segment dis- 

 tinctly narrower than the apical hair-band, dullish, with very 

 nnmerons minute but distinct punctures; apical dorsal 

 segment black (covered with light hair in suiicicola) ; second 

 s.m. broader, receiving the first r. n. about the middle (con- 

 spicuously beyond the middle in *(///6'/co/«). From C. amrri- 

 cuna, Cresson, it is readily known by the colour of the 

 thoracic pubescence, dull surface of first abdominal segment, 

 much darker stigma, somewhat larger malar space, and 

 labruni with the lateral pits distinct. The anterior eoxic 

 have a small apical hairy prominence, but nothing deserving 

 to be called a spine; the wings are whitish hyaline (not at 

 all yellowish) ; the inner claw-tooth is shorter than the 

 outer, and arises from the middle of tlie claw ; the hind spur 

 is very obliquely microscopically pectinate, but with a Land- 

 lens the ai)pearanee of a very fine ciliation is all tliat can 

 be seen, and that with difficulty ; the clypeus is shining, 

 with strong punctures running in grooves, and a median 

 (lei)ression. 



In Robertson's table this runs to C. evhiphi, Hob., but 

 tlie colour of the thoracic pubtscenee is quite ditrerent, 

 the posterior tarsi are black, and the abdominal hair-bands 

 are very broad. The sculpture of the first and sicond abdo- 

 minal segments is quite diUcrcnt from that of C. suUcicula 

 ycruiiii, C'kll.
