median cariniform tubercle. Clasper reduced distally ; harpe 

 with a pointed apical hook and several, more proximal, teeth.

Imago. — 3 . Intermediate between tatarinovi and rubricosa ; 

 fore wing as strongly falcate as in the latter, but red below 

 in basal half as in certain specimens of the former. Tongue 

 very weak ; pilifer with very few bristles. Expanse : 77 mm. 



Tenth tergite similar to that of r. rubricosa, narrower,, 

 apex more suddenly narrowed, curved downwards, pointed ; 

 ninth tergite with long hair-scales as in r. rubricosa ; sternite 

 reduced, without lobe. Clasper widened distally into a sub- 

 quadrate flap, bearing dorsally on the inner surface a high 

 triangular crest, which is continuous with the subdorsal fold 

 of the more proximal part of the clasper ; this fold is rough, 

 with setiferous tubercles ; harpe somewhat resembling that 

 of A. elwesi in the shape of the distal part but is less concave, 

 and has. besides the long apical hook, a short subapical hook 

 at the dorsal edge ; the proximal ridge high. 



Hab. W. Himalayas (Murree). One <£ in the Tring Museum, 

 also one $ in British Museum from Shillong. £ and early
