coutinuous bands on segments 2 to 6. Clypeus slightly convex, the 

 lateral portions separated by a notch, which appears as a small black 

 spot. Base of mandibles overlapped by a brush of hairs. Scape short 

 and stout, somewhat curved ; flagellum pale rufous beneath, first joint 

 about one-fifth longer than the second. Tegulne with a hyaline margin. 

 Wings hyaline, apex strongly fuliginous, nervures and stigma black. 

 First abdominal segment subglobose, a little longer than broad ; second 

 very similar to those following. Apex and venter entirely black. The 

 anterior edge of the clypeus is black, and feebly tridentate. 



Hah. — Deming, N. M., in numbers flying round a bush of 

 Zizijplius hjcioidcs, July 9tli, 1896. I cannot identify this with 

 any described species ; and Mr. Fox, after comparing it with the 

 collections at Philadelphia, writes, "apparently distinct from any 

 here." It would seem to be near Cjinitima, Gv., from Illinois ; 

 but it differs in colour of stigma, absence of spot behind eyes, 

 and has more yellow on the prothorax. Among the N. M. species 

 it is recognised by the black and yellow legs and abdomen, 

 without any ferruginous, the absence of spots on vertex, the 

 spotted scutellum, the supraclypeai mark, and the first abdo- 

 minal segment not elongate. Specimens have been sent to 

 Amer. Ent. Soc. and U. S. Natl. Mus. 



I have before me other examples of C. acanthopliiUis, with the 

 following data. Four at flowers of Solidago canadensis, Las 

 Cruces, N. M., August 24th and 26th. Two on flowers of 

 Bocrhaavia erecta, Las Cruces, August 23rd. They show 

 remarkable variation in size; the smallest (from Boerhaavia), 

 6 mm. ; the largest (from Solidago), 9^ mm. The markings are 

 constant, except that the 6 mm. example has a band (instead of 

 two spots) on first abdominal segmeut.
