Female.—Length 2 mm. Head menisciform, as wide as thorax; 
frons narrow, the frontovertex approximately four times as long as 
broad, narrowest at front ocellus, expanding slightly below this point, 
and sharply expanded above the lateral ocelli; ocellar triangle acute; 
anterior ocellus about its own diameter from eye margins; lateral 
ocelli less than their own diameter from eyes; eyes large and conspic- 
uously hairy; surface of frons with small, close, shallow punctures 
none of which are distinctly umbilicate; face and cheeks very finely 
reticulate-punctate, the sculpture somewhat finer than that of frons; 
scrobes subtriangular, not deep; malar space equal to approximately 
one-third eye height; head, in lateral view, moderately thin, rounded 
in front, frons not prominent. 
Antennae inserted at clypeus; scape subcyiindrical, very slightly 
broadened medially, not nearly reaching to front ocellus; pedicel a 
little more than twice as long as broad; funicle six-jointed, all the 
joints transverse, and successively increasing in width from first 
to last; club very large, fully as long as funicle and distinctly much 
wider than the last funicle joint, oval, rounded at apex, and distinctly 
3-jointed. Thorax short and broad, only a little longer than broad; 
pronotum strongly transverse, opaquely sculptured; mesoscutum fully 
twice as broad as long, very finely and densely reticulate punctate,

reticulation. Forewing reaching well beyond apex of abdomen, nearly 
two and one-half times as long as broad, evenly ciliated basad of 
fenestra as well as elsewhere on disk; marginal vein about three times 
as long as thick, stigmal nearly twice as long as marginal, postmar- 
ginal distinctly longer than stigmal; hind wing reaching about to 
apex of abdomen, and about half as broad as forewing. Legs rather 
long; median tibiae a little longer and thicker than posterior tibiae ; 
spur of median tibia about three-fourths as long as basal joint of 
tarsus; median tarsus moderately thick, tapering slightly toward apex, 
the under side of first segment hairy but without distinct spines. 
Abdomen broadly sessile, about as long and as broad as thorax, sub- 
triangular, rounded at apex, weakly reticulated, somewhat shining;
