the posterior angles of the lateral lobes of the pronotum are pro- 
duced outwards on each side in a straight narrow spine, whereas in 
E.. indicum the spine on each side of the lateral lobes is curvate for- 
ward. In EF. bivmanicum. the posterior angles are triangularly 
produced, not aculeate, and the body is shorter.

Eugavialidium angulatum, sp. nov. 
Colour ochreous. Vertex subequal in width to one of the eyes, 
on either side dentate but not elevated above the eyes; dorsum 
of pronotum plain, punctate, and minutely subreticulate ; between 
the shoulders provided with a short elevated line or ruga on each 
side; humeral angles very obtuse-convex; the lateral and median 
carinae unarmed, not at all tuberculate; median carina little ele 
vated subgibbose at the sulci forward and terminating in front 
over the occiput in a tubercle; prozonal carinae forward behind 
the front margin compressed parallel; the front lateral margin on 
either side armed with a tubercle; posterior angles of the lateral 
lobes of the pronotum turned outwards and little triangulate pro- 
tuberant, not spined; hind process of pronotum produced beyond 
the apices of the hind femora about the length of the femora ; 
wings fully explicate, reaching to the apex of the process; pos- 
terior femora rather stout, margins above crenulate with indis- 
tinct antegenicular lobe, margin below entire; posterior tibial 
margins dentate, a little expanded toward the apices, the first 
joints of the posterior tarsi with the margins little expanded ; the 
three pulvilli equal in length and planate below. 
Entire length of female 23 mm.; pronotum 21°5 mm.; post. 
femora 8°5 mm. 
Habitat.—Calcutta. 
This species is labelled: ‘‘ Gaviahidium philippinum, Bol..”’ 
evidently in Saussure’s handwriting. It is much smaller than 
that species and it differs in the shape of the posterior angles of 
the lateral lobes.
