at level of apex of clavus, with four veins reaching apical margin, 
Cu, forking level with junction of claval veins; anteroapical margin 
of tegmen minutely serrate. 
Pale yellow, in life powdered a whitish fawn; lateral margins of 
vertex and frons, apical joint of rostrum, middle portion of abdominal 
tergites and genitalia fuscous; tegmina subopaque, powdered a very 
pallid fawn, veins concolorous; wings hyaline. 
Anal segment of male long, tubular, deflexed through 40° beyond 
anal opening, bent before apex to point downward. Pygofer with 
sides slightly curved, ventrally curving backward to medioventral 
process, process subtriangular, truncate at apex and minutely notched 
medially. Aedeagus with a tubular sclerotized basal portion and an 
eversible apical lobe, the former with two spinose processes adpressed 
on right side at base, one process curved backward, downward, then 
upward, the other curved backward and upward, and bifurcate in a 
pincerlike manner apically; the flexible lobe complex and symmetrical, 
three spinose processes directed backward, arising near its base on each 
side, and above them a spinose process, slightly swollen in middle, 
directed obliquely upward and backward, a pair of large, somewhat 
bladelike, processes directed posteriorly, each swollen before apex, then 
narrowing to a deflexed sinuate filament; between these ventrally a 
pair of simple spinose processes directed posteriorly, curved upward 
distally. Genital styles in side view sinuately tapering to apex, a 
broad rounded flange projecting dorsally one-third from base, emar- 
. ginate in middle of its upper edge, a minute outwardly directed tooth 
basad of the emargination, a digitate process, adpressed to side, 
arising near margin just distad of it. 
Anal segment of female short, in side view with postanal portion 
deflexed through 60°. Lateral styles broad, curved inward, with 
dorsal and ventral apical angles shortly produced and bent mesad. 
First valvulae with four or five teeth on dorsal mb, two spinose 
processes at apex of ventral limb. Posterior border of pregenital 
plate almost semicircular. Egg ovoid, smooth, transparent, 0.45 by 
0.26 mm. 7 
Described from 15 males and 21 females taken by the writer at Santa 
Margarita, Trinidad, B. W. I. (June 15-20, 1942), resting in numbers 
on a single bush of Cordia cylindrostachya. Holotype male and 
allotype, U.S.N.M. No. 56691; paratypes in B.M.N.H. This species is 
distinguished by the shape of the aedeagus and of the posterior lobe 
of the pregenital sternite.
