point. The endomeral plate is shorter, has the distal portion nar- 
rower and longer, and has the anterior end narrower and with certain 
differences in detail of structure. The head in the male is longer, 
at both occiput and temples and very much wider at the temples. In 
the female the frons is much wider and is elliptical in shape instead 
of circular, while the length of head at both occiput and temples, as 
well as the width at temples, varies but little. There is considerable 
variation in the width of the temples in a series of 16 males, ranging 
from 0.65 to 0.74 (average, 0.0673). These 16 males were taken on two 
individual hosts, but both narrow and wide temples were found equally 
in both series. 
In both brevipes and mexicanus the males have the head wider than 
long, while in the females the length and width are practically equal.

JD eanpegin Tate race differs from el brevipes and meaicanus 
in smaller size and different shape of the endomeral plate (see figs.). 
The head is much narrower at the temples in proportion to the width 
of the frons, while the prothorax is very noticeably shorter and nar- 
rower than the male of brevipes, but almost the same in the female, 
while it is much narrower than the female of mexicanus. 
The genital armature is narrower and longer, with the paramers 
thicker and more curved apically and with a lateral constriction
