sjjiracle long; 1st segment of abdomen unusually globose toward apex and with 

 the 2nd aliove and valves of terebra black: remaining segments rufous, more or 

 less mottled with black; 2nd segment yellow or yellow rufous beneath; posterior 

 tibiae and spines and the four anterior legs yellow, except a line on anterior fem- 

 ora before, the intermediate coxre and two-thirds of femora, which, with the pos- 

 terior legs are black; wings smoky hyaline. 



Three specimens. N. Y., Ct. 



The abdomen of the females toward the apex is wide, flattened, as in 

 OpTiion, and truncated obHquely at end. The spaces above the carinas 

 on metathorax are punctured so as to appear striate in some lights and the 

 summit of the angle enclosed by the carinas is shining rugose.

9. Black, abdomen jiartly rufous. Eeseml)les C. argenteus, from which it differs 

 as follows: — Antennae piceous only toward tip, face somewhat contracted below 

 antenupe; metathorax so jjunctured as to appear granulate, and covered with white 

 hair, except in basin; basin transversely wrinkled and striate to summit, not shin- 

 ing; first segment and upper part of second nearly to its apex black; second seg- 

 ment yellowish beneath; remainder of abdomen rufous, darkest toward end, and 

 not widely flattened nor truncate as in C. argenteus ; first segment not more globu- 

 lar at apex than in other species; legs as in C. argenteus, with more of black at 

 base, anterior coxse black; posterior tarsi blackish. 



% . The male has the two apical segments of the abdonien black and the four an- 

 terior legs wholly or mostly yellow. The antennae are a little longer than those of 

 the female. 



Four specimens. Mass. (Scudder), Ct. 



One couple taken pairing in June. This male has a yellow spot on the 

 front of first article of antennae. One specimen has the first segment of 

 the abdomen and the posterior tibiae almost entirely rufous. 



This may be considered a variety of C. argenteus.

 ovate; basal half of first segment, a spot on second segment above and valves of 

 terebra black; the four anterior legs with yellow tibife and tarsi, reddish toward

9- " Black, with the abdomen and two posterior feet ferruginous; with the four 

 anterior feet, the mouth and base of the antennse yellow."

markings of the abdomen, having the first segment yellow in its narrow
