70. Cyanirts pus]pa. 

 Polyommatus puspa, Horsfield, Cat. Lep. E. I. Co. p. 67. n. 3 (1828). 



S . Near Assam. 



Two of the three examples obtained seem a little aberrant, 

 and may belong to a distinct but allied species ; thej are, 

 however, in poor condition, and it is possible that the species 

 may vary somewhat both in the width of the outer border on 

 the primaries and in the size and prominence of the markings 

 on the under surface. I have, however, failed to notice 

 similar variation (excepting where due to seasonal polymor- 

 phism, as in the North-American species) in the allied species. 

 I do not find any characters to warrant the separation of the 

 other male from Horsfield's Javan type. 



71. Nacaduha ar dates. 



Lyccena ardates, Moore, P. Z. S. 1874, p. 574, pi. Ixvii. fig. 1. 



Near Assam. 



Four damaged males were obtained, no two of them abso- 

 lutely alike in the pattern on the under surface of the prima- 

 ries. A nearly allied " species " described by De Niceville 

 (Journ. Asiat. Soc. Beng. vol. lii. p. 72, pi. i. fig. 13, 1873) is 

 separated from the above by its superior size, by the abbrevia- 

 tion of the band crossing the cell on the under surface, and by 

 the absence of the lowest spot in the discal series. The speci- 

 mens before me vary from 22 to 24 millim. in expanse of wing ; 

 the band is only abbreviated in one of the larger specimens, 

 and, though all have the full number of sections to the discal 

 band, the last two sections (they can hardly be called spots) 

 are sometimes in line and sometimes decidedly out of line ; 

 the failure of the last spot of a discal series or the last section 

 of a discal band is of frequent occurrence in the Lycsenidee ; 

 tlierefore, since both N. ardates and N. hhutea appear to be 

 common in Sikkim, I feel some doubt as to the validity of 

 the latter as a distinct species ; at the same time, with only 

 the figure of this form before me I cannot positively assert 

 that it is not distinct *. 



72. Lampides elpis. 



Polyommatus elpis, Godart, Enc. Meth. ii. p. 654. n. 125 (1823). 



S . Near Assam. 

 We have this species also from Silhet ; the Indian examples 



* I have, since tlie above was written, seen one imperfect specimen of 

 N. hhutea in Mr. Moore's collection ; I should certainly hesitate to de-, 

 scribe so uearlv allied a form myself.
