FULGOROIDEA OF TRINIDAD—FEN NAH A477 
ventrally a thin flat lobe tapering distally, underlain by a short 
sclerotized subtriangular setigerous lobe pointed distally; second 
valvulae narrow, converging apically. 
Described from one female collected by Dr. J. G. Myers, Trinidad, 
B. W.I. (January 1932). Type, U.S.N.M. No. 56702. 
OPSIPLANON, new genus 
Head, with eyes, not quite so wide as pronotum; vertex flat, not 
hollowed out, produced almost half its median length before eyes, 
twice as wide across basal angles as long in middle, lateral margins 
carinate, longer than middle line, strongly converging anteriorly in a 
straight line, or nearly so, median carinae strongly present throughout, 
posterior margin shallowly excavated; frons rather longer than wide 
at widest part, flat or scarcely tumid, somewhat curved in profile, 
lateral margins diverging to below level of antennae then curving 
inward to suture, median carina distinct, percurrent, lateral margins 
shghtly elevated, a transverse carina at base, which with lateral 
carinae of vertex and margins of frons enclose a small triangular 
areolet on each side; clypeus about as long as frons, slightly tumid, 
with median and toe al carinae; antennae small, gauodl segment aie 
globose. Pronotum short, sneer margin convex, posterior margin 
broadly excavated, disk sali median and lateral carinae, anterior 
margin carinate behind eyes, with three carinae to posterior margin, 
lateral margins carinate, with a carina below them; mesonotum tri- 
carinate, lateral carinae diverging posteriorly. Tegmina rather nar- 
row, costal and commissural margins parallel to apex of clavus, mem- 
brane somewhat expanded distally, fork of Sec+R+M one-seventh 
from base, Sc+ R fork at nodal line, or very near it, M forking at nodal 
line, with three branches reaching apical margin, Cu, forking level 
with apical quarter of clavus, claval veins joined distally by an oblique 
cross vein, a series of nine apical cells distad of apex of costal cell, a 
series of six subapical cells, the first small, trapezoidal, the third 
small, triangular. Wings with R simple to apex, six apical cells before 
Cu,. Posttibiae with a single spine in basal half.
