Pseudoleria robusta Garrett 
FIGURE 39 
Pseudoleria robusta Garrett, 1925b, p. 2. 
This species is likely to be confused only with Pseudoleria subro- 
busta, new species, from which the male can be easily distinguished 
by the presence of two stout spines on the ventral edge of the hypan- 
drium. The size and coloration is similar to that given for P. parvi- 
tarsus Garrett, except that the legs on specimens examined have been 
more yellowish than in P. parvitarsus Garrett. The cheek-eye ratio 
is from 0.35 to 0.44. 
DistTrisuTion.—British Columbia, Washington, California, Utah, 
Montana; March-April, July—October. 
BroLtocy.—This species has been collected from a swallow nest, 
according to the label on a specimen in the U.S. National Museum. 
Pseudoleria subrobusta, new species 
FIGuRE 40 
This species has the same coloration as described for Pseudoleria 
parvitarsus Garrett, except that the anterior crossvein of the wing is 
slightly darkened. The hind basitarsus of the male is longer than 
the following segment. The cheek-eye ratio is from 0.48 to 0.60. 
The species is best recognized by the appearance of the male ter- 
minalia. The absence of stout spines will distinguish P. subrobusta, 
new species from P. robusta Garrett. In the former there is a single 
short toelike projection at the posterior corner of the distal edge of 
the epandrium. 
Typres.—Holotype (male) and allotype: San Joaquin Experiment 
Station, Madera County, Calif., 22 Feb. 1953, collected by P. D. 
Hurd. Paratypes: 1 female with same data as holotype and allo- 
type; 1 specimen of each sex from Redlands, Calif., 14 Dec.; 1 speci- 
men of each sex from Morengo Valley, San Bernardino, Calif., 28 
Mar. 1952, collected by E. L. Schlinger; 1 male from Calienti Moun- 
tain, San Luis Obispo County, Calif., 14 Mar. 1953, collected by 
K. W. Tucker; 1 male from Davis, Calif., 14 Mar. 1953, fermented 
syrup bait, collected by E. C. Carlson. 
The holotype and allotype have been deposited in the U.S. National 
Museum (USNM 65442). Paratypes have been deposited in the 
State College of Washington and the University of California at 
Davis and at Berkeley. All types were from the collections of the 
University of California at Davis and at Berkeley. 
DisTRIBUTION.—In addition to the type specimens from California, 
I have seen 1 male from Wheeler Springs, Tex., 30 Oct. 1949, col-
