Vertex hollowed out, width between basal angles equal to or only 
slightly less than length in middle, 1.6 times width at apex, sub- 
angularly emarginate at base; transverse carina rounded apically, 
apical carina almost obsolete, a quadrate cell in middle line between 
anterior and posterior transverse carinae; base of frons visible from 
above, its anterior border in dorsal view slightly convex; frons almost 
flat in middle, raised near sides to form broad flanges in which a clear 
fenestra is situated a short distance in from the margin at the level of 
the antennae on each side; lateral margins diverging from base to 
level of antennae, thence evenly curved inward to frontoclypeal 
suture; width of frons 1.2 times length in middle, width at apex twice 
width at base; median ocellus present; median carina forked at ex- 
treme base, percurrent on frons and clypeus; rostrum reaching to apex 
of abdomen. Pronotum short, carinate medially and with lateral 
carinae following the posterior margin of the eyes, posterior border 
acutely angularly emarginate; mesonotum with five carinae, the in- 
termediate pair almost complete. Posttibiae with three spines. 
Vertex testaceous, areolets fuscous in middle; frons pale testaceous, 
a fuscous band on each side of middle line, fenestrae hyaline; clypeus 
fuscous, almost piceous basally on each side of median carina; genae 
pallid yellow, antennae testaceous; rostrum fuscous, piceous at tip. 
Pronotum fuscous anteriorly, pallid yellow on disk and between post- 
ocular carinae and posterior margin; mesonotum fuscous, a piceous 
band along middle line and outside lateral carinae. Legs testaceous, 
femora reddish fuscous. Abdomen testaceous, a piceous band along 
middle line dorsally, two round dark spots near each lateral border; 
sternites pallid, fuscous near sides anteriorly; genitalia testaceous. 
Tegmina hyaline, ivory yellow; stigma pale yellowish brown, a narrow 
fuscous spot in cell posterior to it; transverse veins overlaid with — 
fuscous patches; apical cells distally fuscous, that of Cu:, being wholly 
infuscate; veins dark, sparsely and minutely granulate. Wings hya- 
line, suffused fuscous near apical margin, veins fuscous, minutely 
eranulate. 
Anal segment of male tubular, not greatly produced behind anal 
opening, ovate in dorsal view. Aedeagus complex, consisting of a 
sclerotized tube directed horizontally backward with a membranous 
flagellum attached apically, reflected forward to lie above and to the 
left of the sclerotized limb; a large thick spine near base of aedeagus on 
right side curved outward then inward; two small spines on left side 
arising close together on a slight ridge, one directed outward, the other 
curved angularly inward and slightly upward; a large thick spinose 
process arising at about same level, crossing from left side to right and 
projecting outward and upward above aedeagus on right side; membra-
