 cence, and with long lemon-yellow pubescence at base; apical margin 

 of all the segments with a broad fascia of veiy dense, short, pale 

 ochi'aceous or whitish pubescence. Length four lines. 



The 3 is narrower, with the pubescence longer and more dense, 

 and white on cheeks, thorax beneath and legs; antennae longer; the

 Hah. Mass., Del., Va., 111. (Coll. Am. Ent. Soc.) 

 Readily distinguished by the short, robust form, short wings, lemon- 

 yellow pubescence of head and thorax, and by the broad abdominal 

 fascise. The space between the eyes and base of mandibles is unusu- 

 ally short. 



8. C. simulans, n. sp. 3. Black, shining; head densely and 

 finely, tliorax deeply, punctured, both clothed witli long, dense, fulvo- 

 ochraceous pubescence, palest on face, cheeks, thorax beneath and 

 metathorax; clypeus rugose, metathorax sculptured as in C. amerirana; 

 wings hyaline, faintly dusky at apex, nervures black; legs black, with 

 ochraceous or whitish pubescence; abdomen closely and uniformly 

 punctured; basal segment with long, pale ochraceous pubescence, the

Hah. Colorado. Mr. Jas. Ridings. (Coll. Am. Ent. Soc.) 

 Closely allied to C. ainericana S , but is larger, with longer wings, 



the abdomen more densely punctured, and the fascia; broader and 



more dense. 



9. C. consors, n sp. S .■ Differs from C. .simulans by the more 

 finely punctured thorax, narrower second submarglnal cell, more 

 robust legs, shorter and stouter hind tibiffi, and more delicately punc- 

 tured abdomen; this is more hairy, having long, thin, ochraceous 

 pubescence, more obvious on the two basal segments, and becoming 

 shorter and more or less mixed with black toward apex; the jiubes- 

 cence of the fasciise is less dense, not so appressed, and pale ochra- 

 ceous. Length four and one-half lines.

 rather short, dense, hoary pubescence; base of metathorax coarsely 

 reticulated; tegula; piceous; wings short, hyaline, ncTvures rutb-testa-
