384 MR. H. J. ELWES ON SOME [May C), 



The only difference of colour in this form that I see is that the 

 three lower ovate apical glassy spots on the fore wing are in the 

 Naga specimen yellow, not white ; in the Sikkim specimens this 

 colour is paler, and does not extend to the outermost of the three 

 spots. This difference holds good in a very small specimen of his- 

 trionicus type from Mandi in the N.W. Himalaya, which from its 

 size I at first thought to be altissima. In this respect the variety 

 shows some resemblance to C. sikhimensis, but I can distinguish 

 all specimens of the latter with certainty. As this form appears 

 in Sikkim at least to be confined to high elevations, I propose to 

 call it C. histrionicus, var. altissima (Plate XXXIII. fig. 1). 



Campylotes siKKiMENsis, D. sp. (Plate XXXIII. fig. 2^.) 



This species I have long hesitated to separate from the last, which 

 it resembles closely in size, but as I have now four specimens and have 

 seen others in Messrs. Druce and Moore's collections which agree 

 pretty closely, I am obliged to give it a name. 



c^ 5 . Differ from G. histrionicus in their much smaller size 

 (c?46-51 mm., $ .'il-61 mm. in expanse); in having all the 

 marks on the fore wing pale yellow, which are vitreous white in 

 C histrionicus ; in the hind wing the red stripes are divided near the 

 margin by a black line, outside of which the markings are yellow as 

 in C. desgodinsi, Ob. In one specimen only this character fails, 

 making it intermediate between C. sikkitnensis and C. histrionicus 

 var. altissima, but on the underside the apex of the hind wing 

 clearly distinguishes it from the latter. 



At the apex of the fore wing are two additional spots not seen in 

 any specimens of histrionicus, though in two of the var. altissima 

 there are small white specks in the same position. 



On the underside the markings are also different, and leave no 

 doubt in my mind that this is a different species. It occurs rarely 

 on Tonglo at 10,000 feet with the last, where I took a male in August 

 1886, and received three others in the same collection, made by 

 natives in the Chumbi Vallev, which contained the new butterflies 

 I described in P. Z. S. 1882, p. 398. 



Among the numerous beautiful Heterocera sent me by Mr. Doherty 

 were 7 specimens of a Campylotes, which though it agrees in pattern 

 and colour pretty fairly with Campylotes desgodinsi^, is so much larger 

 and brighter in colour, that I can hardly place it under that species. 

 As, however, intermediate forms may occur, I propose to call it 



Campylotes desgodinsi, var. splendida, n. var. (Plate 

 XXXIII. fig. 3.) 



The subjoined comparison is made with a specimen from Ta-tsien- 

 lo in East Tibet, and with a photograph of three others, for which 

 I am indebted to the kindness of M. Charles Oherthiir. 



Much larger, expands 80 mm. as compared with .58 mm. ; very

" The diflevence shown in the Plate between the abdomen of this species and 

 that of fig. 1 does not really exist, and is caused by the yellow bands of the 

 sides showing above in its more distended stale.
