Simuliuni escomeli Ronhand. 
This species appears to he the commonest and most widely distributed 
Siniuliam in w'estern Pern and in nortlieiai ('bile. It was originally 
described from the neighborhood of Areqnipa. Prof, 'rownsend has sent 
specimens from tlie following Peiaivian localities; Santa Enlalia, July 5, 
1911); Lima, iMarch, 1914; Chosica, March, 1914. The National Museum 
has a series from northern Chile, taken by Prof. Carlos E. Porter in the 
Valle de Lluta and the Valle de Azapa in June, 1912. Usually the ground 
color of the scutum is bright ferruginous, hut specimens occur in which 
it is rich chocolate brown. Two females, one from Lima, the other from 
Chosica, show this variation. Tliis species closely resembles in coloration 
.S', bivitlatum from New Mexico and Colorado, hut in spite of this the two 
are readily separable. In S. escomeli the scutellum is broad and blunt, 
while in the North American species it is narrow and drawn out to an 
acute angle. 
Simuliuin flavipictum new si)ecies. 
Female .—Occiput dull black, frons and face wdiite, pruinose; frons 
moderately broad, widening on upper portion. Antennte ferruginous 
yellow on basal half, shading from brown to dull black on distal half. 
Palpi blackish. Scutum ferruginous, marked with ocher yellow some- 
wdiat similarly to S. gaudeatum, hut the mai-kings less regular and less 
sharply delimited; rather broad lateral yellow stripes joining very l)road 
yellow zones along the anterior margin, which latter are broadly divided 
in the middle, involve the prothoracic lobes and are deeply concave on 
their posterior margins; posterior margin narrowly bordered with yellow, 
a narrow median line extending forward to near middle of disk, a trans¬ 
verse yellow shade crossing it before antescutellar depression and sending 
forward branches at its outer angles. Scutellum yellow, broad and ob¬ 
tuse. Postnotum j^ellow, pruinose. Dorsal vestiture of coarse, evenly 
distributed blackish hairs with golden luster. l‘leur;e yellow and ferru¬ 
ginous. Abdomen ferrugiiious yellow at base, dull blackish brown 
beyond first segment. Legs with the femora ferruginous yellow, the 
tibite shading to brown at their apices ; anterior tarsi black, median pair 
with the first joint ferruginous, darker towards the tip, the second i)ale 
at base, the last tliree black; hind tarsi black, with bases of the first and 
second joints yellowish brown ; vestiture of femora and tibife dark with 
golden luster. Claws slender, with a prominent tooth near base in addi¬ 
tion to basal thickening. Wangs clear, the membrane between the sub¬ 
costal and first veins yellow; venation normal; costa and end of first 
vein brown, with black spines and hairs, the subcostal vein yellow, 
llalteres ferruginous yellow.
