translucent, testaceous, marbled with fuscous, though not 
in basal third of corium, three oval spots in cell R, a 
similar spot basally and a fainter spot distally in cell 
M 3 + 4 fuscous-piceous. Veins fuscous-piceous, paler in 
clavus. Transverse veins mostly pallid. 
Anal segment of male elongate-rhomboidal, convex- 
truncate at apex, anal foramen near middle. +Edeagus 
moderately short, tubular, curved upward distally, dorsal 
margin with an eminence on each side at base and at 
middle, the latter bearing a short tooth directed caudad, 
a pair of long spines arising laterally at middle, curved 
outward, cephalad and finally mesad; sedeagus distally 
reflected anteriorly in the form of a trough, striate and 
membranous. Genital styles short and stout, subtri- 
angular, expanding distally; apical process broad, hol- 
lowed out on its anterior surface, minutely pointed at 
apex and with a crescentic plate attached laterally near 
its base. 
Anal segment of female very long distad of anal fora- 
men, deeply rounded at apex. 
Nymph with vertex relatively shorter than in adult, the 
pro- and mesotibiae distinctly foliate and post-tibiae four- 
spined. 
Described from four males and seven females and four 
nymphs taken by the writer on Jost Van Dyke (Feb. 18, 
1944). This species may well prove to be closely allied 
to the Puerto Rican Thionia borinquensis Doz. and the 
Jamaican Thionia impressa Melichar, though it differs 
markedly in the coloration of the tegmina. Holotype $ 
and allotype ? at Mus. Comp. Zool. No. 27819.
