43. Lamp ides celianus, Fabricius. 

 A single male taken in the Terai. 



44. Lampides elpis, Godart. 



A Terai insect. On the wing it presents a very curious appearance 

 on account of its alternately completely opening and shutting its wings, the 

 contrast between the brilliant metallic-blue of the upper surface and the dark 

 dull underside being very great. 



45. Lampides puspa, Horsfield. 



Common throughout the Sikkim hills. This species seems to take the 

 place of L. kasJimira, the commonest " Blue" in the North- West Himalayas, 

 which is aj>parently not found much further west than Kumaon. 



46. Lampides kandarpa, Horsfield. 



A single specimen only taken in the Terai. 



47. Her da epicles, Godart. 



Common in the Terai and lower hills. The genus to which this 

 species belongs is one that is essentially a frequenter of rank herbage, 

 being always commonest where the ground has been disturbed by man, and 

 weeds have sprung up. 



48. Hypolycaena erylus, Godart. 



Males very common all through the Terai and up to Chunabatti. 

 Only one female taken.

53. Pier is nerissa, Fabricius. 

 Papilio amasene, Cramer, pi. 44, A.

 Terai. The Sikkim specimens are always much larger than those from 

 other parts of India.

 Common near Chunabatti. 



55. Tachyris indra, Moore. 



A few males seen near Chunabatti.
