 on each side of the first four or five segments but pale just beneath the spots, 

 pale pubescent; genital claspers (fig. 19) distinctive of the species.

 the dark marks more reduced ; scutellum may be entirely pale or with only a 

 brown streak along the median line, infuscations of corium absent ; geminate 

 mark on tylus, anterior margin of lorae, collum, and marks about the margins 

 of calli, blackish: segment II, length 1.17 mm., slender, enlarged toward apex,

Lcctotypc: S June 22. 1891. American Fork. Utah ( E. A. 

 Schwarz); Cat. No. 24171 U. S. N. M. Plcsiotypc; S, cotype bv 

 Uhler; author's collection. Specimens examined: 26 39 June 22, 9 

 June 24, American Fork. Utah (E. A. Schwarz); 5 July 8, 9, 1882. 

 Yakima river. "Opp. Ellenberg," Washington Territory ( Hagen ) ; all 

 cotypes by Uhler. S "Colo. 2020" which has the median line on front 

 obscured by piceous. The specimen taken by Dr. Hagen near the 

 Yakima river is more heavily marked with black than is the case with 

 the females from the type locality. 



This species was collected by Mr. Schwarz on desert vegetation 

 near American Fork , and, as the color and other characteristics indi- 

 cate, it is a form to be expected only in the arid regions of the 

 United States.
