422 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 95 
Described from one female collected at Caracas, Venezuela, by Dr. 
J. G. Myers (Dec. 23, 1930). Type, U.S.N.M. No. 56675. This spe- 
cies differs from O. maidis (described below), in size, the shape of the 
vertex, and the color, and from other species treated in the present 
report in the shape of the anal segment. 
OLIARUS QUADRATUS, new species 
PLATE 7, FIGURES 42-44 
Female: Length, 3.0 mm.; tegmen, 3.8 mm. 
Vertex hollowed, median length markedly exceeding width across 
base (1.8 to 1), areolets reaching back to one-third from base of lat- 
eral margin, a small quadrate cell between them apically; median 
carina absent, a median notch present basally; greatest length of frons 
shghtly exceeding greatest width (13 to 12), frons shallowly grooved 
near margins; median carina present, distinctly forked near base; 
median ocellus present; lateral margins diverging to below level of 
antennae then curving inward. Pronotum short, lateral carinae di- 
verging to follow hind margin of eyes. Hind tibiae with four spines, 
the basal pair minute; hind tarsi very long, three-quarters as long as 
hind tibiae, the basi-tarsal joint about twice as long as second and 
third combined. Tegmina with M forking about level with apex of 
clavus, Cu forking basad of Sc and R; veins conspicuously granulate, 
each granule bearing a macrotrichous seta. Anal segment a little 
broader than long (1.2 to 1), almost quadrate. 
Vertex, frons, genae, and antennae fuscous to piceous, margins tes- 
taceous, clypeus testaceous to fuscous, piceous near apex; rostrum tes-, 
taceous, apical joint fuscous. Pronotum fuscous, margins testaceous; 
mesonotum and abdomen fuscous. Fore and middle legs pale fuscous, 
tibiae testaceous, tarsi dark, hind femora pale fuscous, tibiae and tarsi 
pale testaceous. Anal segment fuscous. Tegmina vitreous, stigma 
dark, rather broadly ovoid, veins yellow, clouded fuscous, granules | 
clear, bordered fuscous, setae dark; a fuscous cloud across base of 
costal cell, basal cell, and along inner border of clavus; a fuscous spot 
at Sc fork, Cu, fork and on M between these two, and also on commis- _ 
sural margin near its juncture with the united claval veins; a fuscous” 
cloud over all the transverse veins and over the tip of Cuy. Wings 
vitreous, veins pale fuscous. | 
Described from one female collected by Dr. Myers at Caracas, Vene- | 
zuela (Dec. 23, 1930). Type, U.S.N.M. No. 56676. This species 
differs from the preceding in the shape of the vertex, in the forking — 
of the median carina, the proportionate length of the hind tarsus, | 
the color, and size.
