head (inclutling eyes) only about or little more tlian two- 

 tliirds the width ot" base of mesonotum ; pronotal lateral 

 margins ampliatc, the ano;ular apices reaching base of basal 

 cell of teginina, these margins are rounded anteriorly, 

 truncate at middle, thence obli(iuo to basal margin, basal 

 marginal area transversely wrinkled ; abdomen in male as 

 long as i)ronotum and mesonotum together, including the 

 basal cruciform elevation; rostrum reaching the basal seg- 

 ment of abdomen ; opcrcula in male short, transverse, not 

 ])0ssing the basal abdominal segment, slightly rounded 

 laterally and posteriorly, not meeting internally ; anterior 

 femora with two strong spines near apices, posterior tibia? 

 with some long spines on each side beyond middle.

 A species allied to P. hecuba, Dist. 



Dunduhia Tielena, sp. n. 



Body and legs brownish ochraceous ; apical spot to front 

 of head, lateral and posterior margins of pronotum, posterior 

 margin of metanotuni, tympanal coverings, narrow posterior 

 segmental margins to abdomen above, opercula, and abdomen 

 beneath, pale ochraceous; tegmina and wings hyaline, the 

 venation brownish or pale ochraceous ; head about as long as 

 pronotum, the front large and convex, about twice as broad 

 at its base as the length of the anterior margins of the lobes 

 of vertex ; lateral margins of the pronotum distinctly toothed ; 

 abdomen very little longer than space between apex of head 

 and base of cruciform elevation; opercula in male long, 

 extending to base of sixth abdominal segment, strongly con- 

 cavely narrowed on each side near base and thence convexly 

 ampliated ; rostrum scarcely reaching the posterior coxje ; 

 second apical area of the tegmina little more than half the 

 length ot the first.

Hub. N. India; Dehra Dun (Brit. Mus.). 



Allied to D. mannifera, Linn., but differing in the shape 

 of the opercula, which are strongly concavely narrowed on 

 each side near base; the second apical area to the tegmina is 

 very short, distinctly shorter than the corresponding area in 

 D. rnannijera.
