5th moult. — Green thoracial somites hunched, blue specks absent. 

 The larva is full-grown in July, and has a subdorsal row of minute 

 warts. It utters a sharp squeak when disturbed. Food-plant 

 Salix babylonica. The pupa is formed in a green cocoon of a close 

 texture and ribbed down the outside. This cocoon is left open at 

 the top, the lips of it closing together except when pressed ; the lower 

 end is pointed and furnished with a cell perforated from the inside by 

 three or four small holes, aud having a single larger outlet hole on the 

 outside. This presumably acts as a drain if the cocoon should accident- 

 ally become filled with water. The moths always emerged in 

 November at 5,000 feet. 



(Larva feeds on Acer campbelli at Tukvar, 4,000 feet, and on willow 

 at Kurseong in May and June ; imago appears in November [fide Kny- 

 vett].— H. J. E.)

Sikkim, 8,000 feet. (The females of this species have the hyaline 

 spot on the forewing much larger than in the males. — H. J. E.)

Sikhim; Yatung (Thibet), 10,000 feet. I only possess one female 

 taken at the latter place by Mr. Taylor of the Chinese Boundary Com- 

 mission. (The male is not rare at 8,000 to 10,000 feet on Tongloo. —

Sikhim (Hampson). I do not know this species, it seems nearest to 

 S. lola judging from Swinhoe's description of the synonym. (I do 

 not know whether Sir George Hampson identifies Antherea 

 thespis. Leech, described from one female taken near Ichang in China, 

 with the Sikhim insect by comparison, but this does not agree in 

 many particulars with my female. I have a female from Sikhim, 

 given me by Mr. Knyvett, a male from Mr. Gammie taken in July, 

 and a pair of Salassa megastica, Swinh., from the Khasia hills. Though 

 these differ in many points, they are probably so variable that it is im- 

 possible to say from so small a number of examples whether the Chinese, 

 Khasia, and Sikhim insects represent the same or three species. The 

 larva, according to Mr. Knyvett, is like that of S. lola, but is much
