HELEOMYZID FLIES NORTH OF MEXICO—GILL 537 
could not be certain of the structural details. I obtained from the 
Garrett collection a paratype male from which the terminalia had 
been similarly mounted on a slide. I removed the terminalia from 
the slide in order to study its structure more effectively, but this 
preparation is also in very poor condition. The posteroventral mar- 
gin of the epandrium apparently is not evenly rounded, but is drawn 
out into a somewhat pointed apex. This feature fits well with Gar- 
rett’s description of the “disk with the tips moderately produced.” 
I have examined four other male specimens which are the same 
as P. intermedia Garrett, except that the posteroventral margin of 
the epandrium is drawn out as described above. 
Distripution.—California, Arizona, Texas, Kansas; March—July, 
October, December. 
Brotocy.—One specimen in the U.S. National Museum was 
collected “in burrow of Diplodomys’” in California. 
Pseudoleria dubia Garrett 
Pseudoleria dubia Garrett, 1925b, p. 3. 
Garrett’s description, the only one available, is as follows: “An 
imperfect specimen is very close to media but the disk is very narrow. 
Tips rounded but shorter. . .” 
I have examined the type. The terminalia are mounted on a slide 
which is in poor condition and difficult to interpret. 
The type was collected at Sarita, Tex., 30 Nov. 1911. 
Pseudoleria similis Garrett 
Figure 35 
Pseudoleria similis Garrett, 1925b, p. 2. 
The terminalia of the type of this species is mounted on a slide. 
The condition of the slide is too poor for me to be able to make out 
the structural details with certainty, but I believe that the species 
is the same as my “‘species 6,’’ upon which my concept of Pseudoleria 
similis Garrett is based. As indicated in Garrett’s description, the 
fourth tarsal segment of the hind leg is about twice as long as wide 
and its sides are nearly parallel. The best distinguishing character, 
however, is the presence of rather dense bristles on the posterior 
margin in the lower half of the epandrium of the male postabdomen. 
The distal margin of the epandrium is more or less truncate. Aside 
from this, the characters of this species appear to be the same as 
those of P. intermedia Garrett. 
Distrisution.—Idaho, California; February—June, December.
