to an incurved point; a pointed process on dorsal margin toward base, 
a small bifurcate process on ventral margin one-fifth from base. 
Anal segment of female very short, postanal portion minute, lateral 
styles broad, parallel-sided, symmetrically rounded at apex. Ovipos- 
itor with first valvulae with two long spines apically, upturned at 
tip, above these an uncinate process bearing dorsally two or three 
minute spines and two larger spines apically. Medioventral portion 
of pregenital sternite somewhat longer than broad, posteriorly 
smoothly rounded. Egg 0.45 by 0.23 mm. 
Described from 11 males and 9 females taken by the writer in St. 
John’s Valley, Trinidad, B. W. I. (Sept. 21, 1942), resting on foliage.

OMOLICNA RUBRIMARGINATA, new species 
Priate 10, Figures 161-168 
Male: Length, 4.0 mm.; tegmen, 4.7mm. Female: Length, 4.2 mm.; 
tegmen, 5.6 mm. 
Width of vertex across base greater than length along middle (1.8 
to 1), vertex curving into frons apically, not clearly separated from 
it, posterior border very obtusely emarginate; three rows of sensoria 
on each side of middle line, the outer pair on each side with larger 
sensoria than the inner row; frons longer than wide at apex (1.8 to 
1), 1.4 times as wide at apex as at base, lateral margins expanding 
gradually to apex, median carina absent, middle of frons not much 
depressed, a series of about 30 sensory pits inside each lateral margin, 
which is slightly raised; frontoclypeal suture impressed; clypeus 
somewhat tumid with a distinct median carina; no subantennal process. 
Pronotum with antennal foveae large. Tegmina with Sc+R forking 
at basal two-fifths, M with five veins at apical margin, apical margin 
minutely serrate, Sc+R and anterior claval vein with large pustules. 
Head, thorax, and abdominal sclerites testaceous, faintly suffused 
fuscous; rostrum and legs pale stramineous; tegmina transparent, 
yellow, slightly suffused fuscous, especially near stigma; apical margin | 
and sometimes distal portion of apical veins pink, veins otherwise | 
concolorous; wings hyaline, faintly clouded fuscous, veins darker. 
Anal segment of male long, tubular, deflexed through 40° beyond 
anal opening and bent before apex to point downward, no lobe in~ 
middle of ventrolateral margin, but a slight flange before apex.

Pygofer with lateral margins broadly sinuate, curved backward ven- — 
trally into a long tapering median process rounded at apex, keellike 
in lateral view and subequal in length to the pygofer. Aedeagus 
tubular, a pair of slender spines on dorsolateral margin about two-_ 
thirds from base, a large median membranous tube reflected to point
