not entirely wanting; anterior femora elongate, margins entire,

hind femora strongly crassate, very wide toward the base, superior 
margin granose and minutely serrulate, subbidentate toward the 
knees, the antegenicular spine acute; hind tibiae with both mar- 
gins armed with strong spines; first article of the posterior tarsi

Habitat.—Sibsagar, N.-E. Assam (S. E. Peal); Upper Assam 
(Doherty). 
Two examples are labelled with the name “‘ Tetétx dilatatus.’’ 
This species is quite different from dtlatata, de Haan, as evidenced 
by comparison with specimens of this species from Java in my 
collection.

Body strongly crassate, above granose, little rugose; head 
little retracted under the pronotum; face large; eyes strongly 
conoidal in profile. Colour fuscous, variegated with dull yellow, 
hind femora often bearing vertical bars of yellow. Vertex wider 
than one of the eyes, barely emarginate in front, median carina 
very small and low, slightly fossulate on each side; paired ocelli 
placed scarcely below the middle of the eyes; antennae rather 
short, and inserted barely between the lower margin of the eyes, 
apical articles of palpi compressed; frontal costa barely arcuate 
elevated between the antennae, and little depressed between the 
eyes; vertex in profile angulate. Pronotum anteriorly very obtuse 
angulate, when viewed in front the body quadrate, on either side 
of pronotum concave, and above tectiform; median carina of 
pronotum in profile elevated forward, and arcuate compressed 
from the front border to a point backward above the articulation 
of the hind femora, then strongly depressed irregularly sinuate back- 
ward; the dorsum backward planate, broadly fossulate opposite the 
elytral apices; hind process acute cuneate, the lateral carinae 
compressed, the apex reaching to the extremities of the hind femora 
or surpassing them; humeral angles widely arcuate, the humeral 
carinae subobliterated, not at all compressed; elytra sinus shal-
