duced backward beyond the apices of the extended hind tibiae, 
the apex bifid; posterior angles of the lateral lobes turned out- 
wards and produced in a moderately strong spine distinctly 
curved forward. Elytra moderately wide, elongate, the distal 
fourth narrowed to the apices and angulate, externally impresso- 
punctate; wings fully explicate, extended backward to the apex 
of the pronotal process. Anterior femora little compressed elon- 
gate, margin above littie compressed at the basal half, and bear- 
ing a small subacute tubercle, below bidentate; middle femora 
above undulate, below acute bidentate; posterior femora moder- 
ately stout, the superior carina crenulate and bearing an acute 
antegenicular denticle, below strongly dentate, often quadriden- 
tate, the three denticles at the middle strongly produced spinose ; 
hind tibial margins and first joint of posterior tarsi widely ex- 
panded, the first two pulvilli acute and placed backward leaving a 
wide basal space, the three pulvilli subequal in length. 
Entire length male and female 21°7 mm.; pronotum 21-25 
mm.; post. femora 9 mim.

Judging from the description of this questionable species 
which has a length of only six millimetres, it appears that the 
type was a larva or pupa. This leaves the identity of the species 
in doubt. The type came from Bombay. In the Indian Museum 
collection are two specimens from Sibsagar, N. E. Assam, which 
ate labelled Scelimena uncinata, Serville, by Saussure. These are 
pupa of some species near Eugavialidium india, Hance. 
Genus Eugavialidium, Hancock. 
The members of this genus have the paired ocelli placed be- 
tween the extreme lower part of the eyes; the dorsum of pronotum 
deplanate, the front margin of the pronotum more or less ornate 
with denticles or tubercles, often armed with a produced tubercle 
at the middle above the occiput, or when absent there, they ap- 
pear in front on either side of the lateral lobes; the femoral mar- 
gins more or less tuberculate; the lateral carinae on either side 
of the shoulders often tuberculate or dentate, and the median 
carina of the pronotum sometimes tuberculate; the hind process 
strongly prolonged backward beyond the hind femoral apices; the 
margins of the hind tibiae and first joint of the posterior tarsi 
moderately expanded, but not so strongly membrancous dilated 
as in Scelimena; the lateral lobes have the posterior angles out- 
wardly produced, acute, triangular, or on either side bearing a 
spine often curved forward.
