Organs of fliglit equally well-developed in the two sexes, when closed, 

 not quite reaching up to the foliaoeoua lobe of the 5th tergam, obliquely 

 truncate at the extremity, so that the apex in both is subacute and falls 

 just behind the anterior margin, and that there is no anal emargination 

 in the hinder pair. All the longitudinal veins remarkably straight. 



Tegmina with the marginal field tolerably expanded at base, irregu- 

 larly reticulate, and seniiopaque, the anterior radial forked at junction 

 of outer and middle third and its upper prong running to the apex, the 

 posterior radial simple, the stigma long and narrow jjlaced as obliquely 

 as possible across the radio-ulnar interspace aud extended on to the 

 two bounding veins, the anterior prong of the anterior ulnar foi'ked, the 

 cellules of the wide middle part of interspace between the anterior ulnar 

 aud the postoi-ior radial in five transverse rows, the posterior prong 

 of the anterior ulnar 2-branched, the dividens anastomosed with the 

 posterior ulnar some distance short of the margin, the plicate, which 

 all but reaches the posterior mai-gin, broken up into a reticulum contri- 

 buted to by its three branches, none of which enters the anal gusset, 

 which is hence reticulate. Wings with the anterior ulnar simple. 



Legs tolerably long and slender. Pore coxte strongly triquetrous, 

 spinulose on the front crest, rough on the others, the front and outer 

 ones produced at apex to sharp rough spines ; femora strongly curved, 

 obclavate, strongly sinuous and cariuate above and angulate-ronuded 

 near the base below, at the apex trispinose, armed on the outer edge of 

 the lower margin with 6 spines, on the inner edge with 14, on the disk 

 with 3 ; femoral brushes thick, on distinct eminences ; tibiie multi- 

 spinose, the spines divided into several irregular series by long spines, 

 the 1st, 8th, 12th, I6th, 19th, and 22nd of the inner edge, and the 1st, 

 5th, 7th, 9th, 11th, and 13th of the outer edge, being subequal and 

 longer than any of those between tliem. Four posterior femora shorter 

 than the tibiae, 4-ci'ested, with a ridge on each side, both dorsal crests 

 and the posterior ventral crest furnished with large lobulated foliaceons 

 lobes, lateral genicular lobes long, but only half the length of the curved 

 supra-gonicular lobo, which is equal in length to the acioular genicular 

 spines, tibiaj filiform, terete, without a trace of a crest either above or 

 below, their calcaria acicular ; 1st joint of tarsus long, longer than the 

 three following taken together. 



Distribution. — Malayan subregiou of the Oriental Region.

 more clouded with the brown blotches larger aud deeper-coloured, and 

 the posterior lobe of the prouotum more bowed.
