Ormenis squamulosa Fowler.) 
Frons broader than long, lateral margins strongly curved, median 
carina present only in basal half; tegmina with apical and nodal line 
present, the former about equidistant between latter and apical mar- 
gin; costal membrane distad of humeral elevation much broader than 
costal cell; several but not most of the veins distad of apical line 
forked. Hind tibiae with two spines. Anal segment of male only 
slightly deflexed in side view, ventrolateral margins convex, a shallow 
groove between anus and apex dorsally.

Male: Length, 6.0 mm.; tegmen, 6.2mm. Female: Length, 6.0 mm.; 
teomen, 7.0 mm. 
Frons broader than long in middle (1.4: 1). , median carina present 
only on basal half. Tegmina with costal membrane twice as wide as 
costal cell at level of R fork, an impressed fold basad of subapical 
line. 
Head, pronotum, pleurites, and legs pale yellow, sometimes clouded 
fuscous, mesonotum reddish brown, darker laterally, abdominal 
sclerites fuscous, membrane pallid or yellow, genitalia fuscous; teg- 
mina piceous or very dark fuscous, costal margin, and sometimes area 
between costal veinlets, and scutellar margin of clavus narrowly pale 
yellow, Sc testaceous; wings smoky, veins darker. Insect in life 
powdered pinkish brown and gray, rather speckled. 
Anal segment of male short and broad, not deflexed markedly in 
apical half, ventral margin in profile convex, apex bluntly rounded, 
telson arising basad of middle. Aedeagus with periandrium tubular, 
slightly upturned distally; a thin rounded lobe on each side of mid- 
dle line apically, a short stout spine laterad of each directed anteriorly 
with a row of about eleven minute recurved teeth laterally near 
base; lateral margins cleft at apex; a pair of stout shallowly curved 
spines, three-quarters length of aedeagus, arising distally and di- 
rected forward ventrolaterally; ventral surface of periandrium taper- 
ing distally to an upturned point; basad of this point, ventrolaterally, 
a slight ridge on each side bearing about eight recurved teeth; penis 
a simple tube slightly upturned distally, apically bifid, the cleft ex- 
tending for one-seventh from apex, each limb expanded - distally, 
curved dorsally and anteriorly, scroll-like. Genital styles broad, ex- 
panding distally, dorsal margin slightly convex, apical margin
