pale brown. Specimens with only a black bar connecting 
the hind ocelli were described by me as P. virginica ; it is 
only a color form. Specimens without any black on head 
were named P. immaculata by Klapalek, this also is a color 
form. All of these have the genital prongs in the male 
very slender, usually near each other and each curved out- 
ward toward tip ; the subgenital plate shows two lobes with 
truncate tips. 
In 1862 Walsh described two species from Rock Island, 
Illinois ; he put each in a separate subgenus, since one had 
but one branch to radial sector and the other had two 
branches. P. decipiens and P. hrunneipennis usually have 
the black spot covering the ocelli, decipiens has clear wings, 
hrunneipennis has infuscated wings. The genital prongs 
are very similar but quite different from P. placida, being 
much stouter and bent near the middle. 
I consider that these two forms represent but one spe- 
cies, P. decipiens. It is the common form in the mid-west 
from Michigan to northern Texas. However there is a 
black species in this area, much less common, this is Per- 
lesta cinctipes Bks. The body and wings are almost 
wholly black, the edge of the clypeus usually whitish, the 
legs are pale beneath, the setae are pale, but each joint has 
a dark band at tip, the hind femora are pale at base and 
tip, and at tip of hind tibiae. The legs of this species are 
shorter and much less slender than in the other species, 
particularly noticeable in the hind femora. The pale of 
costal margin is reduced, each end of costal area being 
dark. In the female the subgenital lobes are large and the 
tips plainly rounded. In the male the genital prongs are 
very slender and longer than in placida , not, or scarcely 
outcurved at tips. 
In 1914 I described another species, P. texana from 
Texas (Dallas, Kerrville, Victoria, Devil’s River). It is 
yellowish to rufous, the ocelli faintly connected by a dark 
V-mark; legs are pale below with a brown streak above, 
the hind tibiae dark except near tip; hind femur fairly 
slender ; sides of ocellar triangle longer than base. In the 
male the genital prongs are moderately slender, slightly 
outcurved toward tip, and their bases separated by a basal
