FULGOROIDEA OF TRINIDAD—FENNAH 463 
row, almost as long as anal segment, gradually expanding distally, 
rounded at apex, a thin horizontal lobe dorsally, attached at base and 
lying mesad. First valvulae long, narrow, with a row of three small 
simple teeth three-quarters from base on dorsal border, with a sclero- 
tized plate distally bearing on its dorsal border a row of 11 minute 
teeth, short and evenly spaced, each tooth bifid or notched at apex. 
Keg elongate-oval, 0.23 by 0.91 mm., thin-walled, but slightly ex- 
panded into a thickened shallowly domed cap at one pole. 
Described from two females collected by Dr. J.G. Myers at Aruman- 
duba, Lower Amazon (Sept. 17, 19383). Type in B.M.N.H.; paratype, 
U.S.N.M. No. 56779. This species differs from the others in the shape 
of the vertex, being approached only by 7. herdida (Walker) and 7. 
paraherbida Muir in this character, and in the unusually long anal seg- 
ment and ovipositor, as well as in the detailed structure of the valvulae.

Male: Length, 9.0 mm.; tegmen,11.8mm. Female: Length, 9.1 mm.; 
tegmen, 12.0 mm. 
Length of vertex two-thirds width across base, about one-third pro- 
jecting in front of eyes, anterior margin rather strongly curved, lateral 
margins slightly converging anteriorly, basal margin shallowly exca- 
vate, median carina present basally; facet distinct on each side antero- 
apically, subquadrate rather than triangular, base of frons visible from 
above, distinctly swollen in middle between lateral carinae; frons with 
carinae not strongly present, lateral carinae feeble. Hind tibiae with 
four spines. Stigma usually 4-celled. 
Green; a broad orange band overlying lateral carinae of frons in 
basal half, passing into black basally; apex of rostrum piceous, pro- 
tibiae and tarsi fuscous, posttibial spines black. ‘Tegmina vitreous, 
stigma green. Wings vitreous. 
Anal segment of male in side view with dorsal margin curved down- 
ward slightly near base then passing straight to apex, lower margin 
shallowly convex, apex obliquely truncate. Aedeagus tubular with 
two ventral spinose processes arising subapically, directed posteriorly 
and obliquely upward, and two dorsal spines emerging at apex and 
abruptly recurved anteriorly. Genital styles somewhat elongate, lower 
margin convex, dorsal margin with two teeth at basal third, thence 
sloping concavely to apex, a small blunt lobe at apex produced 
posteriorly. 
Anal segment of female short, in side view dorsal margin straight, 
lower convex, apex obliquely truncate. First valvulae each with two
