Pusa, gen. nov. 
Head more elongate than in any other genus of Locustine. 
Front strongly reclinate ; frontal ridge not reaching the 
clypeus, compressed laterally between the antenne. Fasti- 
gium of vertex hexagonal, slightly inclined, forming a 
rotundate angle with the frontal ridge; foveole not 
developed ; upper surface concave, with raised margins. 
Eyes strongly protruding sideways, almost hemispherical, 
slightly higher than long. Antenne filiform, slightly 
thickened in the apical third. Pronotum rounded, narrowed 
and not strongly constricted anteriorly; median carina 
feeble, interrupted by three deep transverse sulci; meta- 
zona about as long as prozona, slightly raised, coriaceous ; 
lateral carine undeveloped ; lateral lobes as long as high, 
with fore angle obtuse and hind angle near 90°, widely 
rounded. Prosternum with anterior margin raised, the 
surface convex, gradually sloping backwards. Mesosternum 
with fore margin straight ; mesosternal lobes almost twice 
as broad as long, with himd inner angles obtuse, rounded ; 
interspace transverse, only slightly narrower than the lobes. 
Metasternal lobes a little longer than wide, rounded poste- 
riorly; interspace longer than wide, more so in male. 
Elytra narrow, almost entirely hyaline, except the basal fifth 
part, where they are subcoriaceous, though still rather 
sparsely venulated; costal area feebly expanded basally, 
gradually narrowing apically, and not reaching the apical 
third of elytra; scapular area reaching the base of apical 
third, coriaceous basally, but entirely hyaline, with very few 
transverse veinlets in the apical two-thirds; discoidal area 
parallel-sided, hyaline, except near the base, with the trans- 
verse veinlets irregular, but not dense, with a well-developed 
false vein; interulnar area slightly narrower than discoidal, 
irregularly, though not densely, venulated, with cellules 
placed in two rows, the false vein being developed, though 
irregular and interrupted ; all areas of the apical half of 
elytra with well-developed false veins and trausverse vein- 
lets forming elongate cellules. Wings hyaline, scarcely 
shorter than elytra, rather narrow. Hind femora very 
slender, with upper keel almost straight, not denticulate ; 
knee-lokes rounded. Hind tibiz quadrangular in transverse 
section, feebly incurved and distinctly widened apically, 
armed with 8 outer and 10 inner spines, without outer 
apical spine; the inner apical spurs are longer than the 
outer ones, especially the lower inner, which is twice as 
long as the outer spurs, and bears a tuft of whitish hairs
