Imago. — $$. Head, thorax and abdomen olive -brown. 

 Thorax without pale mesial band ; lines of abdomen less 

 prominent than in lineosa. Fore wing olive -brown Avith 

 a black patch at base of inner margin ; seven lines in outer 

 half, the short line 6 — or line 3 counting from outer margin — 

 completely merged with 7, the latter generally blacker behind 

 and somewhat undulate ; a black dot at end of cell. Hind 

 wing black with a diffuse pale submarginal band. Exterior 

 spur of mid-tibia generally equal to inner one, but often longer 

 and sometimes a little shorter. Expanse : ^9 90-98 mm. 



<J. Tenth sternite less triangular at end than in lineosa. 

 Large scales of clasper asymmetrical, the proximal side of 

 each scale enlarged, longitudinally folded or ribbed, darker 

 than the distal side ; process of harpe (fig. 123 I) with indications 

 of teeth. Penis-sheath (figs. 123 J, K) almost symmetrical, 

 apex rounded in a dorsal view ; right process somewhat 

 widened at end, dentate, left process vestigial only, there being 

 but a few teeth on that side and no free projecting process. 



Hab. W. Himalayas (Dharmsala ; Simla) andE. Himalayas 

 (Sikkim ; Bhutan ; Khasi Hills) to China, Japan and Siam. 

 We have bred the species in the W. Himalayas and the Khasi 

 Hills, where the larvse are found rather rarely at an elevation 

 of about 7,000 feet and 5,000 feet respectively, and Mell has 

 bred it in S. China.
