Imago. — <£$. Scaling of tip of antenna black. Upperside 

 deeper in tint, dorsal stripe not so pale and sides of body far 

 more red than in r. rubiginosa. Fore wing : interspaces 

 between bands glossy whitish-grey, discal band rather narrower 

 and more sharply defined than in r. rubiginosa, discal line 

 broad, not dentate, band-like. Expanse : $ 80 mm., 

 o 102 mm. 



<$. Tenth sternite not sinuate in dorsal aspect. Dilated 

 apical part of harpe longer than in r. rubiginosa, more heavily 

 spined proximally. Right process of penis-sheath longer. 



Hab. E. Himalayas (Khasi Hills; Sikkim) and China. We 

 have bred the subspecies in the Khasi Hills, where larvae occur 

 rarely during the rainy months in dense forests, at an elevation 

 of about 5,000 feet, usually near water. 



Larva : — 



Final instar. Head rather square in shape, vertex rounded ; 

 true clypeus nearly half length of head, apex minutely rounded ; 

 false clypeus shaped like a gothic arch over apex of true 

 clypeus : labrum one-half the length of and slightly broader 

 than clypeus ; ligula nearly square, as long and as broad as 

 clypeus ; eyes 1 to 4 equidistant in a gentle curve, 6 in line with 

 3 and 4, 5 forming an equilateral triangle with 4 and 6. Sur- 

 face of head moderately shining and set sparsely with small, 

 glassy, bubble-like tubercles. Body as in others of the genus. 

 Horn down -curved, stout at base, tapering gently to a conical 

 tip. Surface of body dull ; a transverse row of rounded 

 tubercles along each secondar}^ ring ; a dorso-lateral line 

 of tubercles from front margin of segment 2 to base of horn ; 

 these tubercles rounded, except for those on the three or four 

 anterior secondary rings on 6 to 12, which are conical, almost 

 -spine-like, the tubercle on the second or on the third ring 

 being longer and more spiniform than the rest ; a line of large 

 rounded tubercles starting at the dorsal line at the front margins 

 of 6 to 11, and running obliquefy backwards and downwards 

 to near the dorso-lateral line of tubercles, forming V-shaped 

 markings, the apex of the V directed frontad. Horn set with 

 small conical tubercles to the tip ; anal flap and clasper faces 

 set with small truncate-conical tubercles.
