reticulated; more conspicuously so on vertex and nota; sparsely 
beset with moderately long hairs. 
Head subequal in width to thorax, not strongly deflected. 
Vertex about four times as broad as long, slightly concave at 
occipital margin. rons, a narrow sclerite bounding anterior 
ocellus, subtriangular along anterior and posterior borders of 
latter. Clypeus (cephalic view) irregularly subpyriform, sub- 
conically raised on each side ectodistad, about one and one-third 
times as long as wide. Eyes subhemispherical, about three- 
fourths as thick as distance from lateral margin to median su- 
ture of vertex. Diameter of anterior ocellus about three times 
that of antennal segment III. Posterior ocelli slightly smaller 
than anterior, somewhat prominently elevated. Antennze about 
one and one-third times as long as width of head including eyes; 
segments I and II short and thick, subequal to each: other in 
length and diameter; III one and one-third times as long and 
about one-third as thick as II; the rest of the segments distad 
subequal in diameter to III. 
Thorax about one and one-third times as long as wide, one 
and one-eighth times as long as thick, slightly arched. Prothorax 
very short, depressed below, and almost hidden by cephalic 
emargination of mesoprescutum. Mesoprzscutum irregularly 
subhemispherical, about as long as wide. Mesoscutum broadly 
crescent-shaped with concave margin directed cephalad, about 
one and a half times as wide as mesoprescutum, about twice 
as wide as long. Mesoscutellum about half as wide as meso- 
scutum, about three-fifths as long as wide, slightly deflected 
caudad; two shallow, broadly concave indentations at cephalic 
margin. Forewings obovate; apex broadly rounded: M+ Cu 
about one-fifteenth as long as R+M-+Cu; first marginal cell 
about three times as large as second; a black, rather incon- 
spicuous spot at anal margin between branches of cubitus; one 
between branches of cubitus and media; and a third between 
branches of media. Legs long and slender; hind leg about one 
and one-third times as long as fore or middle leg; ungues broadly 
curved. : 
Abdomen about four-fifths as long as head and thorax com- 
bined; slightly narrower than thorax. Genital forceps subequal 
in length to anal valve, elongately subovoid, about twice as long 
as wide. Anal valve irregularly subcylindrical, about two and 
a half times as long as wide. Genital forceps and anal valve 
more thickly beset with hairs than adjoining segments.
