Antennx testaceous: head dull black, a spot on both sides in the 
ocular area, ferruginous : thorax dull black, anterior margin and broader 
posterior margin of the anterior lobe yellow and the posterior lobe stria- 
ted yellow: abdomen dull black, immaculate: tegmina fulvous, veins 
whitish, a median band and the apex on both sides emitting a tooth like 
mark, dull black: wings white, dull black at the apex, with a large white 
spot: feet dull black (fabr.). 
29. GHANA SULPHUREA, Hope. 
J.A.S. B. liii, (2), p. 228, no. 38. 
Black: head and thorax spotted sulphureous: basal half of wings 
sulphureous (tegmina divided by an oblique blackish band), apices 
yellowish-fuscous, veins in the obscure parts black (Hope). The teg- 
mina are broadly wrinkled and the drum covers in the ¢ are small, 
leaving the striated internal membrane broadly exposed. 
The following scheme attempts to provide a rough differentiation 
of some of the genera of clear-winged Cicade found in India based on 
Stal’s analysis :— 
A. Anterior margin of posterior part of the first dorsal sezment of 
the abdomen in ¢ emitting a foliaceous lobe which covers the whole or 
part of the tympana or is dilated forwards more or less towards the sides. 
Body oblong or somewhat elongate: first femora spinose or acutely 
dentate beneath: frons usually more or less convex. 
B. (1) Thorax narrowed forwards, lateral margins very often armed 
with a small tooth before the middle: (2) basal cell of tegmina more 
than twice longer than broad: (3) interior ulnar area not or but very 
slightly amplified towards the apex: (4) the ulnar veins very close at the 
base or contiguous. 
I. Dunpusia group. <A and B above. 
1. Leptopsaltria: gens internally near the apex at the base of the 
lores furnished with a tubercle or tumescence: rostrum reaching a little 
behind the last pair of coxe : interior ulnar area of the tegmina not or only 
very slightly narrowed towards the apex: first pair of tibie longer than 
the femora : tympana above covered by a very large lobe : opercula short : 
second and third ventral segments in ¢ with a lateral tubercle. The 
head is narrower than the thorax and the frons is moderately convex. 
2. Dundubia: gens without a tubercle: rostrum not or scarcely 
reaching the base of the last pair of coxw: the opercula are long and
