possesses the wings of a second example placed between talc from 

 the same region, I also possess another female from Sikkim. I do 

 not know any species at all similarly marked to P. parca.

 I have figured what I believe to be a very unusual variety of this 

 species captured at Pilibhit, Kumaon, by Colonel A. M. Lang, R. E., 

 on 16th December, 1887. It is a male, and has a very prominent 

 spot in the lower subcostal interspace of the hindwing ; this spot is 

 semi-transparent, and shews on both sides of the wing. Mr. Elwes 

 refers to this rare varietal form in his paper on the "Lepidoptera of 

 Sikkim."* My specimen has also a pale diffused band on the under- 

 side of the forewing just within the dark anteciliary thread extending 

 from the apex of the wing to the first median nervule ; also a large 

 similarly-coloured discal patch on the hindwing, and a marginal band. 



15. HALPE AINA, n. sp., PL B,[Fig. 8, g . 

 Habitat: Sikkim. 



Expanse : £ , 1*36 to l - 44 inches. 



Description : Nearest to H. kumara, mihi,f of which Mr. Otto 

 Moller possesses eighteen specimens and I six, all from Sikkim. 

 Male. Upperside, both wings of a more tawny-ferruginous colour, due 

 to the entire forewing and the basal two-thirds of the hindwing being 

 clothed with a thick coating of long hair-like ferruginous scales placed 

 upon a deep brown ground. Forewing with two conjoined spots in 

 the discoidal cell, the upper spot answering to the single spot of 

 II. kumara, the lower spot twice as large as the upper ; three instead 

 of two increasing conjoined subapical spots; the two discal spots 

 much the same : the " male-mark," however, instead of being a long 

 continuous black streak of modified scales as in H. kumara presents 

 the appearance of two obliquely-placed yellow spots exactly as in 

 H. gupta, mihi,J which can be teazed out by a pin-point into 

 a quantity of fluffy material like down. Underside, both wings 

 coloured much as in H. kumara. Forewing with the translucent yellow 

 spots as on the upperside. Hindwing unmarked in eight specimens, 

 in one specimen with two opaque pale yellow discal spots. 



Described from five male specimens in the collection of Mr. Otto 

 Moller, and four in my own.
