Imago. — Head rather broad ; ej/cs 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 ; antennce 
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-ivings : 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nervule is obsolete ; lower disco-cellular nervule rather long, curved 
inwardly, joining third median nervule not far beyond latter 's origin ; 
space between first median nervule and submedian nervure unusually j 
broad. Hind-ivmgs : rounded and blunted, except at anal angle, whicli | 
is elongated, prominently lobed, and produced (on submedian nervure) 
into a long, or very long, broad, twisted tail ; costa convex throughout, i 
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 I 
hairy beneath, — tibia shorter than femur, — tarsus about two-thirds the 
length of tibia, obtuse, without apparent articulation, finely spinulose I 
beneath and with a few longer inferior spines at the tip ; of the $ 
about the same size and proportions, but the tarsus with distinct articu- 
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, with 
terminal claws short, strong, and widely apart.
