FULGOROIDEA OF TRINIDAD—FENNAH 419 
and mesofemora tinged rufous, tarsi and postfemora fuscous. Abdo- 
men testaceous, suffused reddish brown. 'Tegmina transparent ivory 
yellow, two faint fuscous spots in costal cell, a spot adjoining stigma 
basally, a diffuse fuscous cloud between R and M extending faintly 
across to claval suture; an irregular pale fuscous band from stigma 
to apex of clavus along transverse veins, a second irregular band 
across middle of apical cells of R and M, distal portion of apical cells 
and apical margin pale fuscous. Wings hyaline, faintly clouded 
fuscous, slightly darker near apical margin, veins fuscous. 
Anal segment of male deflexed through 110° beyond anal opening, 
in side view expanded at apex. Pygofer viewed laterally with an 
angular prominence, a small but distinct emargination below it, whence 
the margin is produced posteriorly into an obtuse angle; medioventral 
process almost quadrate, its posterior margin sinuate and culminating 
ina median point. Aedeagus tubular, a sclerotized horizontal portion 
passing upward at tip into a membranous flagellum, which is beset 
dorsally with a row of thin prominent spines and curves obiquely 
downward and anteriorly to the left side; an elongated sinuate hor1- 
zontal process arising near base of aedeagus on left side produced pos- 
teriorly in a broad spine for two-thirds length of aedeagus. Genital 
styles stout, broad in side view, curved in basal half upward and 
forward through 120° and expanding in distal half into a broad plate 
truncate apically. 
Anal segment of female tubular, 2.5 times as long as broad. Ovi- 
positor narrow, porrect, the sheath longer than the anal segment. 
Described from one male and one female collected in Arena Forest,

Mesonotum with five carinae; frons with a percurrent median carina, 
vertex with an acutely angular or curved transverse carina which joins 
the middle portion of the apical transverse carina, forming an areolet 
apically on each side. Fork of M, and M, in the tegmina nearer to Mf 
than is the fork of M, and My.
