From the foregoing measurements it is obvious that the specimens 
from C. 0. punensis do not fall within the extremes of the measure- 
ments of any of the Mexican material, while the genitalia differ in 
shape, although to no great extent in measurements, except for the 
width at base of paramers. 
The paramers are, however, thin toward the base and much thick- 
ened and rounded at the tips (circular), while in the Mexican mate- 
rial they are not only thicker at the base, but also thicker in the me- 
dian portion and are bent more sharply toward the rapidly tapering 
tips, while the contour of the outer margin (on the bent apical por- 
tlon) 1s concave, not convex, as in the specimens from @. 0. punensis. 
We have, therefore, in the Mexican material, a genital armature 
which, in its longitudinal proportions, resembles that of the specimens 
from C. 0. punensis, while the shape of the paramers is that of P. J. 
longipes (Piaget) ; the body measurements are much greater and of 
different proportions than either P. 7. longipes or the specimens from 
C. o. punensis, but with the female larger than the male and with the
