1930 ] Cuban Tropiduchidx and Acanaloniidse 409 
Vertex, impressed; its median length about half its 
width; surface smooth, somewhat shiny; anterior margin 
projecting in front of the eyes about one-half the median 
length; the posterior margin broadly rounded, indistinctly 
carinate ; lateral margins about as long as the diameter of 
the eyes; diverging at an angle of about 20 degrees with 
strongly elevated carinse which are continuous with the 
lateral carinse of the frons and then curving abruptly 
caudad; lateral margins strongly carinate; nearly parallel 
but slightly diverging for about one-half the length and then 
abruptly converging to the clypeus; clypeal margin indis- 
tinct, the two arms forming an angle of about 45 degrees 
with each other. Clypeus, triangular, shallowly inserted in 
the frons, its width about three-fourths its length. Labrum, 
conical, about one-third the length of the clypeus; its sur- 
face distinctly hirsute. Epipharynx about one-half as long 
as the labrum. Labium, with basal segments small ; second 
segment about twice as long as the distal segment. Man- 
dibular sclerite small. Gense, surface smooth, distinctly 
separated from the rest of the head by lateral carina of 
vertex and frons. Antennae, short, length about one-fourth 
the diameter of the eyes ; the basal segment about one-half 
as long as the distal segment; distal segment cylindric; 
flagellum slender, length about twice the diameter of the 
eye. Ocelli, evident, situated below the horizontal diameter 
of the eye. Compound eyes, large, ventral emargination 
indistinct. Pronotum, short, deeply impressed on either 
side of the median line; anterior margin rather broadly 
rounded, projecting about one-half its length; posterior 
margin very broadly rounded, not parallel with the anterior 
margin; lateral flaps large. Fore legs, coxse large; femora 
stout, about as long as the coxse without evident spines; 
tibise stout, prismatic ; tarsi short, claws weak. Mesonotum, 
large, smooth, shiny; lateral carinse indistinct; disc some- 
what elevated, lateral areas strongly sloping; lateral bor- 
ders elongate. Metanotum, small, triangular. Tegulse, 
about as long as the diameter of the eye; somewhat cres- 
centric with apices blunt. Fore wings, large; costal bor- 
ders nearly straight; apical borders slightly rounded. Ven- 
ation typical; stem of medius about twice as long as the 
basal cell, three branches occurring together, the first
