" "Wings broad : fore wing somewhat short, outer margin nearly erect and slightly scalloped ; 
third subcostal branch bifurcate : hind wing short ; costa abbreviated, lobed at the base, 
concave towards the end, the apex produced and pointed upward ; exterior margin slightly 
concave below the apes, and very convex in the middle ; anal angle lobed ; a spatulate tail 
extending from end of lower median vein ; palpi long, stout, apical joint broad laterally ; 
antenna thickened to apex. 
" Differs from typical Amhlijpodia {A. narada, Horsfield) in the entirely different form of wings ; 
the fore wing having the third branch of the subcostal vein bifurcate instead of trifuroate, as 
in the male of A. narada." (Moore, 1. c.)

" Underside. Anterior wing rufous-brown, the apex grey ; three small white spots within the cell ; 
two spots at the end of the cell margined with white ; the transverse band broad, of nearly

AmUypodia angulata. Leech. — Female. Costa of primaries slightly sinuous, outer margin dentate 
and rather concave from apex to middle. Costa of secondaries convex near the base, then 
concave to the acuminate and vertical apex, from whence the outer margin descends obliquely 
to the middle, when it becomes rounded ; tails are somewhat spatulate. Black, with a strong 
suffusion of bluish purple, intersected by the black venation, on the disc of aU the wings ; 
discoidal spot of secondaries black and bar-like. Under surface of primaries blackish, with a
