"before pupation. The species occurs in the northern part of 

 S. China in jungle of mixed bamboo and deciduous trees, at an 

 elevation of from 1,500 to 2,500 feet. 



The above description of the early stages and habits is taken 

 from Mell, 1922.

Imago. — $§• Much more conspicuously coloured than 

 dyras, sperchius and cristata. Underside : fore wing, a large 

 area between hind angle and R 3 , and an apical patch, of an 

 orange-tawny colour ; first discal line several millimetres 

 proximal of base of SC 5 ; hind wing, a submarginal patch of 

 an orange-tawny colour before anal angle ; first line of hind 

 wing angulate between M 1 and M 2 ; fourth line angulate behind 

 R 3 , 4 to 6 mm. distant from' tip of M 1 . Antenna shorter and 

 thinner than in dyras. Expanse : $ 94-108 mm., $ 118 mm. 



<£. Tenth tergite (fig. 35 D) deeply divided, the lobes slender 

 and obliquely rounded at end ; sternite a low ridge slightly 

 dilated, rounded in middle, mesial lobe short and broad, 

 almost vestigial. Dorso-apical lobe of clasper more curved 

 downward than in sperchius and dyras ; harpe not dentate, 

 long, resembling that of amboinicus. 



$. Ante-vaginal ridge of vaginal plate (fig. 35 E) sinuate in 

 front of vaginal orifice, the lobe rounded ; from each side of the 

 ridge extends a longitudinal fold towards the eighth sternite. 



Hob. E. Himalayas (Sikkim ; Khasi Hills). A few larvae 

 were found and bred by Col. J. D. Campbell, D.S.O., R.E., 

 in the Khasi Hills, in forests with heavy rainfall at an elevation 

 of about 4,000 feet. 



Larva : — 



Final instar. Head rounded-triangular, with a small tubercle 

 on the vertex of each lobe. Surface of head moderately 

 shining, covered with small tubercles. Body shaped as 

 in others of the genus. Horn long, straight, thick at base, 

 and tapering evenly to a strongly, widely bifid tip. Surface 

 of body dull ; a transverse row of large pointed tubercles on 

 each secondary ring ; seven oblique stripes formed of larger 

 pointed tubercles. Horn covered with large pointed tubercles. 



Coloration. — Head grass-green ; a broad whitish stripe 

 separating face from cheek ; the tubercles whitish. Body 

 bright yellowish-green above the spiracles, the tubercles in 

 this area yellow, sometimes with reddish tips ; the area below
