150 BUTTERFLIES. 



Family LYC^NID^. 



255. Geeydus boisduvali, Moore. 



Not uncommon at low elevations from April to October. When 

 flying it has the appearance of a sombre- coloured geometrid. moth. 



256. Paeagerydus horsfieldi, Moore. 



Recorded doubtfully from Sikhim by Elwes. The nearest point 

 to Sikhim that I have received the species is Chittagong. I very 

 much question its occurrence in the Eastern Himalayas. 



257. Allotinus deumila, Moore. 



Very rare ; has been recorded at low elevations from March to 

 May. Mr. Dudgeon has received a good many females from the 

 Leesh river in Daling in March, but no males. Herr J. Rober has 

 proposed the genus MiletograpJia for this species. 



258. Allotinus multisteigatus, de Nic^ville. 



Even rarer than A. dnimila, Moore, and occurs in the same 

 localities with it. The males are more frequently obtained than the 

 females. Both species occur in the Khasi Hills. 



259. PoRiTiA hewitsoni, Moore. 



Occurs throughout the year up to 4,000 feet. I have never seen 

 it alive. Mr. J. Gammie tells me that at Mongpoo in the middle of 

 November it can be taken in thousands, both males and females, and 

 occurs from the bottoms of the valleys up to nearly, if not quite, 

 4,000 feet. It is fond of settling on bamboo leaves, where it exhibits 

 a flash of the most superb blue or green as it opens and shuts its 

 wings. 



260. PiTEECOPS HYLAx, Fabricius. 



Not uncommon at low elevations throughout the warm months. 

 Its pupa resembles the face of an ape. 



261. Neopithecops zalmora, Butler. 

 Common at low elevations from May to October. 



262. Spalgis epius, Westwood. 



Rare in the low villages from May to November. Its larva is 

 carnivorous, and feeds on Cocci ("mealy-bugs"}; its pupa, like that of 

 Pthecops, resembles a monkey's face. 



263. Taeaka hamada, Druce. 



Occurs from the level of the Terai up to 5,000 feet, and flies from 

 April to October. It is not very common. It is found also in Western 

 and Central China and in Sumatra. 



264. Megisba malaya, Horsfield. 



The tailed form is very common in Sikhim, but I have seen 

 only two specimens from thence of the tailless form. It is a
