Vertex longer than broad (1.4 to 1); frons longer than broad (2.6 
to1). Protibiae longer than profemora (1.4to1). 
Bright green in life; lateral margins of vertex at apex, of frons at 
base, lateral carinae of frons at base, a pair of laterad spots at apex 
of each femur, apex of rostrum and posttibial spines black; protarsi 
and mesotarsi fuscous; tegmina vitreous, veins and stigma pale green; 
wings vitreous, veins pale yellow, becoming brown near apical margin. 
Anal segment of male elongate, in lateral view expanding apically, 
sinuately truncate at apex with a small lip protruding posteriorly, 
anus subterminal. Pygofer with lateral margin bent posteriorly | 
almost in a right angle, ventral margin transverse. Aedeagus with 
a short ringlike component at base, extended caudad ventrally and 
furcate at its apex, a large membranous fold, symmetrically biramous, 
with a sclerotized rod, arising from a median common stem, traversing 
the membrane on each side, each rod in ventral view being angularly 
S-shaped, and meeting its counterpart at apex; middle portion of 
aedeagus consisting of a flat elongated plate, stiffened with a pair of 
sclerotized rods, overlying a subrectangular membranous apodeme, 
laterally compressed and apically truncate. 
Anal segment of female similar to that of male. Lateral styles 
broad, with margins subparallel, tapering somewhat abruptly near 
apex, with a setigerous area apicodorsally, a large shallowly domed 
thin flange projecting caudad dorsally joined to lateral portion at 
base; first valvulae with five very small teeth dorsally, passing into 
long grooves at their bases, and two large teeth apically, on inner 
aspect ventrally an elongate foliaceous lobe; second valvulae thin 
and pointed. 
Described from five males and six females collected by the writer at 
St. Augustine, Trinidad, B. W. I., on various dates between July and 
December 1942 on Liberian coffee, Casuarina, and Hibiscus. Holotype 
male and allotype, U.S.N.M. No. 56699; paratype in B.M.N.H.

T'aosa DISTANT, Ann. Mag. Nat. Hist., ser. 7, vol. 18, p. 355, 1906. (Genotype, 
Flata suturalis Germar, Ent. Arch. Thon, vol. 2, p. 48, 1830.) 
Vertex short, not much exceeding eyes, at most as broad as long, 
usually much broader, rounded or truncate at apex, very shallowly 
excavated at base, lateral margins parallel between eyes, or very 
slightly converging, transverse carina at apex curved, a distinct tri- 
angular or quadrangular facet on each side of head distad of junction 
of lateral margins with transverse carina, vertex slightly depressed, 
median carina absent or scarcely present at base; frons not much 
longer than broad, lateral margins sinuate, expanding to below level 
of antennae, then curving inward to suture, median and lateral carinae
