FULGOROIDEA OF TRINIDAD—FENNAH | 443 
anteriorly, with a pair of spines above and a pair below it, projecting 
somewhat beyond its tip, a pair of slender filaments two-thirds as 
long as aedeagus arising at point where it is recurved and directed 
anteriorly above the whole structure. Genital styles broad, expanding 
from base to middle, then narrowing to an inwardly directed point 
at apex; a small lobe between two notches on dorsal border about one- 
third from base. 
Anal segment of female very short, postanal portion minute. 
Lateral styles broad, almost parallel-sided, symmetrically and bluntly 
rounded at apex. Ovipositor with first valvulae with two long spines 
apically, upturned at tip; above these an uncinate process bearing 
dorsally four curved spines near apex. Medioventral process of 
pregenital sternite almost semicircular. 
Described from one male and two females collected by the writer in 
St. John’s Valley, Trinidad, B. W. I. (Oct. 8, 1942), resting on low 
herbage. This species is distinguished by its size, by the shape of the 
frons and vertex, and by the arrangement of the sensoria on the vertex, 
by the shape of the anal segment, by the structure of the male genitalia, 
or in the female by the shape of the hind margin of the pregenital 
sternite, and by the color. Holotype male and allotype, U.S.N.M. 
No. 56690; paratype in B.M.N.H.

Vertex rather narrow, lateral margins raised, converging anteriorly; 
-frons narrow, devoid of median carina, margins raised. Pronotum 
with deep antennal foveae. Tegmina elongate, narrow; Sc+R fork-

clavus, Cu, forking at level of junction of claval veins. Egg ovoid, 
smooth, transparent.
