Imago. — ITcad rather broad ; eyes smooth ; forehead densely 

 clothed with scales and short hair ; palpi separate, parallel, very long, 

 densely clothed with scales and with very short closely appressed 

 hairs, — the second joint long, rather thick, only very slightly ascendant, 

 not rising above middle line of eyes, — third joint long (rather longer 

 and stouter in $), porrected horizontally or slightly deflected ; antenna' 

 short, stout, very gradually thickened from base to extremity, which 

 is blunt. 



Thorax long, very stout, with long silky hair laterally and poste- 

 riorly ; pterygodes long and tufted. Fore-wings : short, broad, sub- 

 truncate ; costa very convex at base, but thence almost straight to 

 apex ; hind-margin more or less bluntly prominent about lower radial 

 and third median nervules ; subcostal nervure with four branches — the 

 first and second originating considerably apart, far before extremity of 

 discoidal cell, the third and fourth short, diverging not far from apex, 

 at which the latter terminates ; radial nervules with a common origin 

 at upper corner of extremity of cell, so that middle disco-cellular 

 nervule is obsolete ; lower disco-cellular nei'vule rather long, curved 

 inwardly, joining third median nervule not far beyond latter's origin ; 

 space between first median nervule and submedian nervure unusually 

 broad. Hind-ivings : rounded and blunted, except at anal angle, which 

 is elongated, prominently lobed, and produced (on submedian nervure) 

 into a long, or very long, broad, twisted tail ; costa convex throughout, 

 but especially at base ; apex rounded ; hind-margin very slightly den- 

 tate on nervules ; inner margins convex and meeting, so as to conceal 

 all but tip of abdomen beneath ; costal nervure terminating at apex ; 

 discoidal cell short, truncate, closed by nervules, of which the lower is 

 very slender and oblique, and joins third median nervule at latter's 

 origin. Fore-legs of $ thick, rather large, scaly, — femur robust, closely 

 hairy beneath, — tibia shorter than femur, — tarsus about two-thirds the 

 length of tibia, obtuse, without apparent articulation, finely spinulose 

 beneath and with a few longer inferior spines at the tip ; of the $ 

 about the same size and proportions, but the tarsus with distinct ai-ticu- 

 lations and minute terminal claws. Middle and hind legs stout, densely 

 scaly, the femur densely hairy beneath (especially in $), tibia a little 

 shorter than femur, with strong terminal spurs, tarsus longer than tibia, 

 its first joint very long (as long as the other four joints together), and 

 thick (especially in hind-legs), very spinose beneath, broad at tip, witli 

 terminal claws short, strong, and widely apart.
