Antennas testaceous : head dull black, a spot on botb 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

 J. A. S. B. liii, (2), p. 223, 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 GicadcB found in India based on 

 Stal's analysis : — 



A. Anterior margin of posterior part of the first dorsal segment of 

 the abdomen in S 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 uhiar area not or but very 

 slightly amplified towards the apex : (4) the ulnar veins very close at the 

 base or contiguous. 



I. DuNDUBiA group. A and B above. 



1. Lejptopsaltria : genee 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 coxse : interior ulnar area of the tegmina not or only 

 very slightly narrowed towards the apex : first pair of tibiae 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. Dunduhia : gense without a tubercle : rostrum not or scarcely 

 reaching the base of the last pair of coxae : the opercula are long and
