OLIARUS MAIDIS, new species 
PLATE 7, FIGURES 45-54 
Male: Length, 3.0 mm.; tegmen, 3.5 mm. Female: Length, 3.0 
mm.; tegmen, 4.5 mm. 
Median length of vertex scarcely shorter than width across base; 
areolets reaching back to midpoint of lateral margins, a small quadrate 
cell between them medially at apex; median carina absent or scarcely 
indicated near notch at base. Frons with lateral margins sinuately 
diverging to level of antennae, thence curving inward to suture; great- 
est width 1.25 times median length; median carina percurrent on frons 
and clypeus, forked very near base. Pronotum with median carina 
and with lateral carinae following hind margin of eyes; mesonotum 
with five carinae, the intermediate carinae long and complete. Hind 
tibiae with two spines, one minute basally, the other at middle. Teg- 
mina with Cu, forking distinctly basad of Sc and R. 
Head piceous, a dull yellow spot at posterior end of areolets; median 
areolet, median carina and lateral margins of frons, outer portion of 
_frontoclypeal suture and second joint of antennae dull yellow. Prono- 
tum fuscous or piceous, lateral carinae and posterior margin dull 
yellow, mesonotum piceous; abdomen fuscous or piceous, membrane 
pallid. Femora piceous, protibiae and mesotibiae testaceous bordered 
fuscous, protarsi and mesotarsi fuscous, metatibiae and tarsi pale tes- 
taceous. ‘Tegmina hyaline, a hght mark at basal end of stigma, veins 
brown with sparse swollen tubercles. Wings hyaline, veins brown, 
granular. 
Anal segment of male broadly ovoid in dorsal view, longer than 
broad (1.3to1). Aedeagus complex, apodeme of penis curving toward 
right posteriorly, a prominent finger-shaped tube lying obliquely from 
near posterior end of apodeme across to left side of aedeagus, a set of 
four spines near its posterior end, comprising two apical spines, of 
which one is curved almost in a circle and the other directed upward 
and backward, and two lateral spines directed forward. Periandrial 
membrane broad, shallowly curved, forming a broad lobe distally on 
right side. 
Anal segment of female very broad in dorsal view, three times as 
broad as long, subtriangular in outline. 
Described from 3 males and 11 females collected by the writer at 
St. Augustine, Trinidad, B. W. I., on maize (July 18, 14, 1942), 
Holotype and allotype, U.S.N.M. No. 56677; paratypes in B.M.N.H. 
This species is distinguished by the shape of the male genitalia and 
in the female by that of the anal segment. 
3b. Media arising from a common stalk with Sc and R.
