well, that tliere is no room to doubt tlie identity of our species. 

 The only discrepancy is in the length, which Fieber gives as 2| lines, 

 while our insect is only 2 lines : but a larger series of examples would 

 probably show that this is the range of the length of the species.

DBSCKIPTION OF AULOCERA WERANG, A NEW SPECIES OF BUTTER. 

 FLY BELONGING TO THE FAMILY SATYBID^. 



BY CAPTAIN A. M. LANG. 



The genus Aulocera was formed by Mr. !Rutler (Ent. Mo. Mag., 

 Nov., 1867, p. 121) to contain the Indian group of Satyri, consisting 

 of Padma (Kollar) and allies. 



Of this group, 5 species have been described, viz. : — Sioaka, 

 Saraswati, Padma, Avatara, and Scylla. 



Of these, the four first named occur in the North-Western 

 Himalaya, while the last is recorded only from near Sylhet, far from 

 the head quarters of the genus. 



In the Simla and Kunawur districts of N. W. Himalaya (with 

 which I am familiar) Sivaha abounds during the rainy season, i.e., from 

 July to October, from the outer spurs overlooking the Indian plains 

 for 200 miles into the interior of the mountain ranges towards the 

 treeless regions of Spiti and Tibet. 



Saraswati is not quite so widely spread, appears later, and dis- 

 appears earlier. In August these two species swarm, in localities 

 afi'ected by them, amongst the luxurious grass pastures on the less 

 wooded slopes of the hills. 



Padma and Avatara I have always found in company, and they 

 have appeared to me as $ and ^ respectively of the same species. 

 They frequent quite different ground to the two former species, and 

 appear at a different season ; flying in May and June on the borders of 

 oak and rhododendron forests at the summits of ranges of from 8,000' 

 to 10,000' altitude. A second brood appears in July in the same 

 localities. They fly with much bolder Nymphalidan flight than their 

 tamer congeners Swalia and Saraswati, and they do not extend out of the 

 Simla district into Kunawur. 



Scylla (described by Mr. Butler, loc. cit.) has never been seen 

 by me. 



A sixth (undescribed) species of the genus has been taken by me, 

 and I diagnose it as follows : —
