Coxae, legs and feet black, fore and middle knees yellowish. 
Fore coxae with white hairs on their anterior surface. Joints 
of fore tarsi as 21-12-9-3-7; those of hind tarsi as 19-13-8-6-6; 
first joint of hind tarsi with an erect bristle below near the base, 
which is about as long as the diameter of the joint. Pul villi of 
fore tarsi slightly enlarged. 
Wings grayish; first vein reaches two-fifths of the distance 
to the tip of the second; third and fourth veins nearly parallel, 
fourth ending just before the apex of the wing; last section of 
fifth vein nearly twice as long as the cross-vein, which is near 
the middle of the wing. 
Described from one male taken by E. P. Van Duzee, at 
Strawberry Valley, Eldorado Co., California, August 15, 1912. 
Type in the California Academy of Sciences. 
Diaphorus spinifer Malloch. 
Chrysotuss pinifer, Bull. 111. State Lab. of Nat. Hist., Vol. 
X, p. 238. 
The pulvilli of the fore tarsi are somewhat enlarged in this 
species and it has very small bristles at the tip of the abdomen, 
these points together with its slender form are enough to place 
this in the genus Diaphorus, especially as that will bring it near 
the species described above, which differs from it in having the 
bristles at the tip of the abdomen larger, the bristle on the hind 
tarsi smaller, and the palpi much smaller, those of spinifer being 
each as large as the face, or nearly so. Simplex Aid. also has a 
large bristle below at base of hind tarsi, but in that species the 
third and fourth veins are much bent. 
I have taken spinifer in Erie Co., N. Y., in August; Ft. 
Erie, Ont., July; Alpine, San Diego Co., Calif., April; Sacra- 
mento, Calif., June; Dr. Aldrich took it at Lewiston, Idaho. 
It was described from Illinois.
