EPORMENIS ARIPENSIS, new species 
PLATE 15, Frcures 447-454 
Male: Length, 6.0 mm.; tegmen,6.3mm. Female: Length, 5.7 mm.; 
tegmen, 6.3 mm. 
Frons broader than long (1.4:1). Tegmina with costal membrane 
1.8 times as wide as costal cell at level of R fork, apical areoles short,. 
two-thirds length of subapical areoles, apical margin rounded, slightly 
oblique, apical angle more broadly rounded than sutural angle. 
Pale green; dorsal surface of second antennal joint, tibial and tarsal 
spines black. Insect in life powdered greenish white. | 
Anal segment of male with apical portion deflexed through 45°, 
slightly longer than basal portion, a small broad lobe medioventrally at 
base. Aedeagus tubular, curved upward distally, with a pair of stout 
spines of half its length arising from middle line ventrally near apex, 
diverging and directed anteriorly. Genital styles broad, dorsal margin 
straight, ventral margin convex, upturned distally, apical process in 
form of a broad tooth tapering rather rapidly to an incurved point. 
Anal segment of female short, rather broad, deflexed at apex. Ovi- 
positor with lateral styles broad, thick, with stout teeth on posterior 
margin in two irregular rows; first valvulae with four blunt teeth 
apically. 
Egg ovoid, distinctly compressed laterally, truncate obliquely at one 
pole, slightly crescentic in profile, with a long groove extending for 
three-quarters of length from one pole, with greatly thickened margins, 
minutely canaliculate; a pair of shallow longitudinal depressions 
weakly present on opposite side of ega@; length, 0.9 mm., width, 0.3 mm. 
Described from one male and one female taken in forest on Aripo, 
Northern Range, Trinidad, B. W. I., by Dr. J. G. Myers (Nov. 29, 
1930), and one male and female taken by the writer on Cordia sp., St. 
John’s Valley, Trinidad (Aug. 20, 1942). Holotype male, U.S. N. M. 
No. 56708; allotype female in B.M.N.H. This species differs from O. 
unimaculata Fennah in the venation of the tegmina, in the shape of 
the genitalia, in the absence of a black spot at the apex of the clavus, 
and in the presence of one on the antennae. It is possibly conspecific 
with O. albula Walker, but as the type of albula has the abdomen miss- 
ing the relationship cannot be settled with certainty.

Ormenis unimaculata FENNAH, Proc. Ent. Soe. Washington, vol. 48, p. 209, pl. 21, 
figs. 27, 28, 1941. 
The anal segment of this species is asymmetrically cleft or deeply 
emarginate laterally near apex, and the aedeagus also is markedly
