Descriptions of Indian Acridide. 505 
Hycracris, gen. nov. 
Slightly recalls in habitus the genus Catantops. Antenne 
filiform. Front very oblique in male, less so in female ; 
frontal ridge subparallel, with margins obtuse; fastigium of 
vertex sloping towards the frontal ridge; impressed from 
above, widened anteriorly, obtusely marginated, side-margins 
very thick, obtuse. Distance between the eyes a little 
broader than the width of the frontal ridge between the 
antenne: eyes oblique, oval. Pronotum almost conical, 
especially in female; without lateral keels, but its disc some- 
what flattened (more so on metazona) ; median keel feeble, 
in male almost undeveloped on prozona and perceptible on 
metazona only, interrupted by three feeble transverse sulci ; 
metazona much shorter than prozona, obtusely angulate 
behind ; lateral lobes longer than high, narrowed anteriorly, 
with the lower margin obtusely angulate in the middle, fore 
margin oblique, straight, forming a very obtuse, rounded 
angle with the lower margin, hind margin excavate near the 
straight hind angle, oblique and straight from there upwards. 
Prosternal tubercle hairy, large, in the apical half thickened 
and bent backwards, with obtusely conical apex; hind part of 
prosternum adjacent to mesosternum inflated in the middle, 
in shape of an obtuse tubercle directed forwards, touching 
the apex of prosternal tubercle. Mesosternum also slightly 
projecting forwards ; its lobes subtransverse, with the ner 
margins rounded, divergent; hind angles obtuse, rounded ; 
interspace rather broad. Metasternal lobes contiguous in 
male aud separated in female. Elytra developed, strengly 
narrowed towards the apex, coriaceous in the basal half and 
subhyaline apically ; veins straight. Wings developed, 
narrow. Fore and middle tibiz somewhat thickened. 
Hind femora rather long, moderately thickened basally, 
gradually narrowed apically; outer carine obtuse, the 
upper one entirely undeveloped in basal half; upper margin 
not dentate ; knees armed with five sharp spines: one upper, 
two lateral ones, and two on the lower lobes, the latter 
being especially strong and sharp. Hind tibiz rounded in 
the basal third, but very strongly dilated and flattened on 
the upperside towards the apex, outer margin much lami- 
nated between the spines, which are themselves compressed 
laterally ; inner margin with a fringe of dense hairs between 
the spines; seven outer spines and ten inner ones ; no outer 
apical spine; inner pair of spurs much larger than the 
outer pair. [first joint of hind tarsi much flattened, second
