FULGOROIDEA OF TRINIDAD—FENNAH ADT 
B. W. I. (June 12, 1942). Type, U.S.N.M. No. 56673. This species 
is close to H. truncatum but is readily distinguished by the lateral mar- 
gins of the cephalic process being straight, the vertex being propor- 
tionately narrower than in ¢runcatum, by the frons in profile being 
straight, not slightly concave, by the lateral carinae of the frons being 
perfectly arched in a curve where they meet basally, not slightly 
angulate, by the distinctly more slender protibiae, and by the shape 
of the anal segment of the female. 
Genus RETIALA Fennah 
Retiala FENNAH, Proe. Biol. Soc. Washington, vol. 57, p. 88, 1944. (Genotype, 
R. proxima Fennah, ibid.) 
Vertex longer than broad (about 1.5 to 1), slightly curved upward 
anteriorly, basal margin shallowly excavated, lateral margins straight 
or very slightly convex between eyes, thence narrowing to apex in a 
straight line without an abrupt constriction in front of eyes, not quite 
meeting at apex, joining lateral margins of frons; sides of frons visible 
in dorsal view, and junction of lateral carinae of frons visible beyond 
apex of vertex, median carina feebly present on vertex, a short feeble 
carina at base on each side; frons narrow, longer than broad (about 
9.5 to 1), widest at basal third, lateral margins sinuate, median carina 
percurrent, thick at base, narrowing apically, lateral carinae diverging 
as far as basal two-fifths, then sinuately converging to meet in middle 
line at apex, between these carinae frons somewhat tumid; clypeus 
narrow, tricarinate; rostrum reaching beyond postcoxae; antennae 
with basal segment short, second segment ellipsoidal, studded with 
sensory pits, the terminal segment inserted dorsally and exteriorly 
before apex of second. Pronotum produced anteriorly in middle, 
posteriorly angularly emarginate, tricarinate on disk with the lateral 
carinae becoming obsolete basally, an impression on each side of mid- 
dle line, two carinae at lateral margin of each side, between eye and 
tegula; two carinae on each tegula, mesonotum elongate, tricarinate, 
disk flat. Legs long and slender, protibiae longer than profemora, 
posttibiae typically with four spines. Tegmina rather long and nar- 
tow, Sc+R+M stalk about half as long as basal cell, Sc+R forking 
just before stigma, level with apex of clavus, M forking at middle of 
tegmen, Cu, forking at apical third of clavus, stigma with three cells, 
a nodal line and a subapical line of transverse veins present, R typi- 
cally with three branches at apical margin, M with seven, Cui, with 
three, Cu;, with two. ‘
