disto-internal spur two-thirds as long as the metatarsus, second joint of tarsus 
elongate-elhptical in outline.

Differing from the above description of the type in the following features. 
Pronotum less strongly transverse, the caudal width not more than one-third 
again as great as the length, with the cephalic narrowing less pronounced, more 
nearly quadrate. Tegmina falling short of the apex of the abdomen by about 
one-third of their length, when closed and seen from above rectangulate in 
form, the greatest width of the dorsal field of the single tegmen contained more 
than twice in the tegminal length: costal margin strongly arcuate proximad, 
faintly arcuate-emarginate mesad, thence broadly and gradually arcuate to 
the rotundato-truncate apex of the dorsal field; sutural margin nearly straight: 
venation pronounced, elevated; of the dorsal field regular, composed of six 
longitudinal veins, with about four intercalated false nervures, all connected 
by a variable number of cross-nervures ; of lateral field composed of the straight 
mediastine vein and three supplementary nervures, the first marginal and 
strongly sinuate, the second brief and incomplete, the third parallel to and equally 
developed with the mediastine vein. Ovipositor faintly longer than the 
cephalic femur, moderately falciform, slightly more so proximad than else- 
where, division of valves at three-fifths of length from base, apex strongly 
acuminate, dorsal and ventral margins and contiguous margin of dorsal valves 
finely serrulate: subgenital plate short, subrostrate. Caudal tibiae witii all 
spurs more elongate than in the male, the proportions of the distal ones to the 
metatarsus and each other remaining the same, the ventro-internal one more 
tapering: caudal metatarsus more elongate and slender, distinctly longer than 
the remaining tarsal joints, disto-internal spurs hardly more than one-half 
as long as the metatarsus. 
.\U of the material of this species before us either has been immersed in 
alcohol, and therefore has a coloration clearly not that of nature, or is so badly 
damaged that the color of certain portions of the body cannot be ascertained on 
account of their absence. The following color description is therefore a purely 
composite one, drawn from the entire series. Pronotum, genae, face, cephalic 
and median femora except for narrow, pale, distal sections, and the proximal 
half ($) or aU (cf) of the abdomen, blackish brown. Tegmina of the female 
of the same color. The tegmina of the male, the distal portion of the abdomen 
in the female, the caudal femora, the extremities of the cephalic and median 
femora, and aU of the tibiae and the tarsi except as qualified as below, warm l^uff 
to ochraceous-buff . The head has the occiput pale, to a greater or lesser degree 
with fuscous, which generally resolves itself into a quadrilineate pattern ; eyes 
margined caudad, ventrad and occasionally dorsad with j)ale, a pale infra- 
ocular line on the genae indicated; eyes hair brown to cinnamon brown; 
antennae pale with the proximal joint infuscate; palpi very pale, the distal 
joint marked di.stad more or less distinctly with fuscous. Ovipositor of female 
pale, ferruginous washed distad. Caudal femora with a fine dorsal and another
