316 J. Wood-Mason — Ethiopian and Oriental Eepresentaiives [No. 3, 



spike-like erect tootli at the middle of its hinder margin, and is separat- 

 ed off from the vertex by a transverse groove. Eyes narroiv, oval, 

 convex laterally, produced above the level of the lateral lobes of the 

 vertex, armed at the upiJer and outer angle with a large stout blunt 

 somewhat curved finger-shaped non-faceted corneal spine. 



Pronotum roof-shaped with transversely convex sides, surmounted 

 by a raised dorsal line, which is continued to the extremity of tho 

 abdomen. 



Abdominal sterna produced in the middle of their hinder margin ; 

 terga 1-7 produced in the middle postorioi'ly to a delicate filamentous 

 process, the last a broadly concave-truncate triangle with the sides 

 arched. Cerci broadly foliaceous, 13-jointed, broadest at tho antepenul- 

 timate joint, reaching but little beyond the 7th stei'uum, tho upper ajjex 

 of their last four joints produced so that their upper margin is bluntly 

 dentate and their apex bifid. 



Organs of flight extending nearly to the exti-emity of tho abdomen. 

 Tegmina semiopaque, sub-coriaceous, parallel-sided ; the mai-ginal field 

 irregularly reticulate ; the longitudinal veins of anterior area nearly 

 parallel to the margins with their interspaces narrow and divided by 

 false veins ; the posterior area and its gusset produced, with its longitu- 

 dinal veins veiy oblique ; the anterior prong of anterior ulnar simple 

 and unbranched, posterior prong 6-branched ; the dividens anastomoses 

 with the posterior ulnar some distance before the margin, the '1-branchod 

 plicata goes to the margin, its 1st and 2nd branches running parallel 

 with it, but dissolving into a common reticulum at varying distances 

 from the margin, and its 3rd and 4th traversing the anal gusset, which 

 is hence venose. Wings hyaline except in the anterior mai'gin and 

 ajDcx ; apex blunt not extending far beyond that of the posterior ai'ea ; 

 anal emargination slight, obtuse-angular ; anterior u.lnar forked at about 

 the junction of second and aisical thirds of its length. 



Fore-legs long and slender; coxm expanded for fully the apical 

 third of their anterior crest into a conspicuous dentate foliaceous lobe ; 

 femora narrow, slightly sinuous above, that is to say, faintly convex 

 basally and then shallowly concave to the apex, which is produced, as 

 in the pi-eceding genus, forwards and upwards over tho femoro-tibial arti- 

 culation into a Bupragenicular spine, below weakly arched at base, armed 

 on the straight outer edge with 5 spines, on the inner with 11, and on the 

 disk with 3 ; tibiee straight, paucispinose, terete above. Posterior legs 

 similar but longer and slenderer than in the preceding genus, and fur- 

 nished with curved acicular genicular spines longer than the genicular 

 lobes, the lateral ones of which are longer than the dorsal. 



Distribution. — Himalo- [Chinese] subregiou of the Oriental Region,
