of any black on the clypeus. The female also lacks any black on the 

 dypeus and further differs from pulla in having a fascia on the scu- 

 tellum and in having the fascia on the first tergite very broad and 

 without a median anterior emargination. On this species the cly- 

 peus, frons, and thorax, in general, are more silvery than are these 

 same parts on pulla. The femora on the female of pulla are more 

 or less heavily marked with black; on w'gentata the femora of the 

 female are entirely yellow. 



SPECIMENS EXAMINED 



California: San Diego County (Coquillett). 



Mexico: Angeles Bay (June 25-27, 1921, E. P. Van Duzee).

The male of this species may be recognized by the emarginat« 

 middle femora, the bituberculate second sternite and rudiments of 

 similar processes on sternites 3 and 4, and by the shape of the genital 

 stipes. The female may be known by its small size, and its non- 

 emarginate white tergal fasciae, which unite with the fasciae on the 

 sternites to form continuous rings around the abdomen. The second 

 cubital cell is much narrower on the radial vein than it is on the 

 cubital. ^

Florida: Jacksonville (Ashmead). 



Texas: Brownsville; Cotulla (April 15, 1906, F. C. Pratt); Sabinol (May 26, 

 1910, F. C. Pratt) ; Sweet Water (June 19, 1909, F. C. Bishopp).

Only the male of this species is known. It is closely related to 

 /S. femorata Fox, from which it can be distinguished by its more 

 extensive maculations, richer yellow color, and particularly by the 

 form of the genital stipes. It is not represented in the collection of 

 the United States National Museum. The type is in the collection of 

 the University of Kansas, in which State the only specimens known 

 were taken.
