FULGOROIDEA OF TRINIDAD—FENNAH 499 
rowing towards apex, apical margin somewhat rounded with five 
stout incurved spines, a deflexed spine subapically near dorsal margin; 
second valvulae wedge-shaped in lateral view, narrowing posteriorly 
with a thin dorsal cowl not quite overhanging apex; first valvulae 
narrow, rather flattened, upturned to a point apically, with four 
short longitudinal ridges, evenly spaced, each ending in a tooth on 
apical margin, the dorsal two ridges on each valvula with a few teeth 
subapically, a narrow wedge-shaped minutely setose process attached 
at base of valvula, adpressed to its inner face. 
Described from two females collected by F. W. Urich in Trinidad, 
B. W. I. (1917). Type in British Museum mounted piecemeal on 
two microscope slides. Paratype, U.S. N. M. No. 57188. The quad- 
rate vertex, the three series of areolets, the closely reticulate venation 
of the tegmina and the shape of the valvulae of the ovipositor readily 
distinguish this genus. 
EUHYLOPTERA, new genus 
Head with eyes about as wide as pronotum; vertex short, rounded 
into frons, apical margin in dorsal view slightly rounded, posterior 
margin shallowly concave, overlapped by pronotum; frons broader 
than long (about 1.2 to 1), flat basally, depressed near suture, median 
carina weakly present in basal half, absent in apical half, lateral 
carinae obsolete, lateral margins arcuate, not raised; clypeus devoid 
of carinae. Pronotum about as long as eyes, anteriorly convex, trans- 
_verse in middle of margin, posterior margin angularly excavated, an 
impression on each side of middle line, a short ridge behind eyes; 
mesonotum with disk flattened, devoid of carinae. Hind tibiae with 
two spines before apex. Tegmina nearly 2.4 times as long as wide, 
costal margin strongly convex on basal two-thirds, thence slightly 
concave to apex, apical margin straight, obliquely truncate, forming 
an angle of 70° with the distal third of the costal margin, and one 
of 105° with the distal quarter of the commissural margin, apical 
margin nearly four-fifths as long as greatest width of tegmen; R 
forking at basal quarter, M forking just distad of R fork, Cu, fork- 
ink slightly basad of R fork, apical line irregular but distinct, sub- 
apical line irregular, short. Wings about as long as tegmina. 
Anal segment of male narrow, rather broader apically, deflexed in 
apical third, apical margin rounded, deeply notched, with a channel 
medially to anus, telson arising halfway from base. 
Anal segment of female long, about as long as posttibiae, ovate, 
tectiform, anus subterminal. Ovipositor with lateral styles, small, 
subtriangular. Egg bluntly ovoid, smooth, not operculate. 
This genus recalls Cyarda Walker but differs in the shape of the 
tegmina, which are relatively shorter, not so narrowed, and without
