the antciin.'c : lahial palpi long ; the basal joint clongato-tri- 

 angular, the second and tliird slender, long, and nearly equal: 

 eyes prominent, suhglobose. 



Thorax — prothorax 'hidden, provided with long hairs ; meso- and 

 metatliorax scarcely hairy, shining ; the former long, narrowed 

 posteriorly, with a broad concave space in tlie middle above ; 

 the metathorax is much narrower, also with a concave median 

 space, in the centre of the posterior portion of which is a tri- 

 angular metascutellum. 



Legs moderately long and slender, pubescent, the tibiae with also 

 stronger and spine-like hairs mixed with the pubescence ; tarsi 

 long ; spurs 2, 2, 4, furnished with spine-like, closely adpressed 

 hairs, similar to those on the tibia itself; the tvvo pairs on the 

 posterior tibiae ai^e very loiig, and placed near together, the sub- 

 apical pair being situated at about five-sixths of the distance 

 from tlie base. 



Wings — anterior wings narrow at the base, tlie apex widely di- 

 lated, the apical margin oblique ; costa at the base provided 

 with an inturned lobe, which is fringed with strong hairs; a 

 small obtuse lobe at the base of tlie dorsal margin ; fringes very 

 short ; the whole of the membrane is thickly clothed with scales 

 (very short inflated hairs) above, least dense at the base and 

 apex ; parallel with the apical margin, but at some distance from 

 it, is an impressed furrow in which tlie scales are very dense ; 

 near the anal angle this furrow meets a longitudinal pouch, 

 extending somewhat obliquely along the dorsal margin, and 

 running into the base of the wing ; neuration indistinct ; sub- 

 costa straight ; radius parallel with the subcosta, and appearing 

 to end in a fork on the costa (but this fork is somewhat uncer- 

 tain) ; the two branches of the ramus discoidalis ending in 

 long forks, the upper one connected with the radius by a trans- 

 verse veinlet ; discoidal cell small, closed ; a transverse veiulet 

 connects the lower fork with the upper branch of the ramus 

 thyrifer ; this latter appears to end in two forks ; the lower 

 branch long and simple ; the ramus clavalis and cubital veins 

 are concealed in the pouched fold : posterior ivings shorter than 

 the anterior, obtusely rounded at the apex, broad, the dorsal 

 margin towards the base with a very long fringe ; the membrane 

 is without scales, but is rather thickly clothed with procumbent 

 hairs ; subcosta and radius scarcely separated ; ramus discoidalis 

 ending in two long forlcs ; the upper branch connected witli tlio
