pallid, three small pallid spots on lateral margins in basal half, the 
lowest extending on gena to ocellus of each side, a short pallid bar 
transversely on middle of frons level with second lateral spot, not 
reaching to lateral margins, clypeus narrowly and interruptedly pale 
at suture, lateral margins pale, a pale spot at their distal end, and a 
short transverse bar across clypeus at this level, genae with margins 
pale below antennae, and transversely pale at level of suture, antennae 
with second segment fuscous; pronotum fuscous, disk much paler, 
carinae pale testaceous, edged fuscous, mesonotum yellowish brown, 
fuscous anteriorly, median and lateral carinae pale testaceous, edged 
with fuscous, a pale crescentic spot on each side of median carina near 
middle, a round pale spot, incomplete, with a fuscous inner ring and a 
pale center, near base of each lateral carina mesially, a narrow trans- 
verse fuscous bar before scutellum, which is palely margined; tegmina 
semitransparent, dull yellowish brown, veins concolorous, bordered 
-with transparent round spots, an interrupted series of pale areas 
between node and apex of clavus, apex of membrane submarginally 
‘fuscous, veins of membrane and apical margin pale; wings clouded 
smoky, veins darker. 
Ovipositor with lateral styles broad, in profile both margins con- 
vex, the dorsal margin strongly so, curved downward distally to 
bluntly pointed apex with narrow apical membrane, styles curved 
mesad distally, a horizontal dorsal lobe directed posteriorly lying 
mesad and attached at base; second valvulae narrow, rodlike, con- 
verging distally; first valvulae ventrally with a thin membranous 
tapering process directed caudad, underlain by a sclerotized rounded 
lobe, about half as long as membrane and toothed minutely on apical 
border, dorsally a process sclerotized on upper margin which is de- 
curved apically and bears three teeth three-quarters from base and 
two large spines distally. 
Described from two females taken by the writer in St. John’s Valley, 
Trinidad, B. W. I. (Aug. 10, 15, 1942), resting on low branches of 
shrubs. Type, U.S. N. M. No. 56703. | 
This genus is distinguished by the flat and prominently carinated 
vertex, by the venation of tegmina and wings, and by the shape of 
the lobes of the lateral styles of the ovipositor; the species is distin- 
guished by its size and by the color pattern.
