it is very distinct from male flexipes by the normal middle tarsi. 

 The flagellum is bright ferruginous beneath ; scape yellow in 

 front ; clypeus with a broad yellow band ; mandibles strongly 

 bidentate ; labrum yellow, with the usual dark spots, its lower 

 edge with a little median notch, and a broad shallow excava- 

 tion on each side of it ; end of abdomen with a pair of short, 

 blunt, light ferruginous teeth, and very short dark lateral 

 spines. 



Anthophora cnrta Provancher. 



Alamogordo, May 7 to 15, many of each sex ; Highrolls, 

 June 11, $ s. This excellent series led' me to go over the 

 whole of the available material of curta and its varieties, with 

 the result of finding that A. curta peritomae Ckll. (Ent. News, 

 Oct. 1905) is a perfectly distinct species. In the male of gen- 

 uine curta, there is at the apex of the abdomen a long plate, 

 broad basally, and narrowed apically, where it is truncate. 

 The lateral spines are strongly developed and black. In male 

 peritomae the abdomen ends in a pair of short light ferrugin- 

 ous spines, so that with the slender dark lateral spines the 

 abdomen is quadrispinose. In the females, the difference is 

 not so obvious, but the hair on the inner side of the hind basi- 

 tarsus is very dark brown or almost black in A. curta, clear 

 ferruginous in A. peritomae. The yellow clypeal band is very 

 broad, and extends practically to the eyes in A. curta, but in 

 A. peritomae there is usually a wide interval between the ends 

 and the orbital margins, while in the middle it sends a con- 

 spicuous pointed process upwards, this being usually absent in 

 curta. The marginal cell of curta is very short ; in peritomae 

 it is more produced apically. 



A. curta in my collection comes from San Pedro, California, 

 July 10, a male peculiar for having the clypeus all black 

 {Ckll.)-, Juarez, Mexico, May 12 {Ckll.); L,as Cruces, N. M., 

 male, Aug. 23, at flowers of Wedelia incarnata, female, May 

 12, at Dithyrea wislizeni {C. H. T. Towyisend); Mesilla Park, 

 N. M., males, Aug. 14, at plum flowers, Sept. 17, at Pedis 

 papposa {Ckll.). I find no specimens from Northern New 

 Mexico or Colorado.
