cephalic margin of pronotum; a dark brown, very broadly linear 
spot bounding median suture of vertex, occupying about one- 
third total area of latter, and continuous thence through 
longitudinal ental half of genal cones. Body and appendages 
sparsely beset with rather long hairs; genal cones densely hirsute. 
Head scarcely narrower than thorax, very slightly deflected. 
Vertex about one and a half times as broad as long, slightly 
and broadly concave mediad, broadly cleft at caudal margin. 
Ocelli large, subequal to each other in diameter; anterior more 
prominent than posterior. Eyes subhemispherical, slightly 
thicker than distance from lateral margin to median suture of 
vertex, dark brown. Genal cones porrect, long, slender, subconi- 
cal, rounded apicad, noncoalescent, more densely hirsute ventrad 
than dorsad, about three times as long as diameter at base, 
slightly shorter than vertex. Antennz about twice as long as 
width of head; segments III to IX slender. 
Thorax robust, less than twice as long as wide, slightly 
arched. Pronotum about one-third as long as vertex; pronotum 
and cephalic two-thirds of mesoprescutum with a broadly sup- 
pressed, longitudinal, median carina which terminates cephalad 
in a short, horizontal, subtriangular emargination. Meso- 
prescutum and mesoscutum with a pair of abruptly subconical 
projections at lateral margins. Hind legs about twice as long 
as thorax; hind femora and tibixe relatively thick; the latter 
somewhat hirsute, equipped with moderately large, subconical, 
divergent spurs basad and subdistad, and four black spines 
and a number of bristlelike hairs apicad; ungues_ broadly 
curved. Forewings about four times as long as wide, hyaline — 
and membranous, with a faint brownish tinge, subacute at apex; 
cubital petiole and pterostigma wanting; Rs about half the 
length of M, the two veins subparallel; first marginal] cell about 
one and a half times as large as second; a large, elongately 
subtriangular, dark reddish brown mark along anal vein 
between Cu, and base of wings; a very small, much less 
conspicuous, subtriangular, light brown spot between branches 
of cubitus, another between branches of cubitus and media, 
and a third between branches of media, near apex. 
Abdomen subequal in length to thorax; about twice as long 
as wide. Genital forceps slightly longer than anal valve, 
both subconical, rounded apicad. 
Female——Anal and ventral valves about one-third total 
length of abdomen, the former slightly longer than the latter, 
subequal to each other in diameter, both subacute apicad, slightly
