Adris sikhimensis, a new Form of the Ophiderid Group of 

 Noctuid Moths. By A. G. BUTLER, Ph.D. &c. 



FOR some years past we have had a single example of a 

 moth in the Museum collection which I felt certain was 

 distinct from the widely distributed A. tyrannus] but, as 

 Mr. Hampson was inclined to the belief that it was merely an 

 instance of individual variation, I abstained from describing it. 

 Mr. Moore's collection has now added three other examples 

 from Davjiling, clearly demonstrating the fact that the Sikhim 

 form differs constantly in certain characters from the widely 

 distributed form of the East. I therefore no longer hesitate 

 to name it. 



Adris sikhimensiSj sp. n. 



General character and pattern of A. tyrannus, from which 

 it differs in having the primaries much more largely suffused 

 with moss-green ; the sinus at the inner margin of these 

 wings considerably longer; the curved black band on the 

 secondaries with its upper portion constantly much wider and 

 the large black reniform patch with its inferior lobe much 

 enlarged, reducing the acuteness of the external indentation j 

 the third joint of the palpi terminates in a decidedly smaller 

 expansion than in any example of A. tyrannus. 



Expanse of wings 100-118 millim. 



Darjiling. 



I believe this to be a perfectly distinct representative form 

 of A. tyrannus ; for although individuals vary in some of 

 the characters which I have pointed out, there is nevertheless 

 a wide difference between the nearest forms of the two types.
