season brood of G. Mineus in their general larger size, more angular apex to the 

 forewing, and uneven exterior margin of tlie liindwing. On the forewing above, the 

 median ocellus is conspicuously of larger size. On the underside, the transverse 

 subbasal and the discal line are both well defined and prominent. The male is 

 distinguishable by having the glandular patch on both wings clothed with scales of a 

 yellow colour (not blackish, as in G. Mineus), the patch on the underside of the fore- 

 wing being also of much greater length, and extending upon the submedian vein 

 from the middle to the transverse discal line, and it is moreover, composed of 

 differently shaped scales. According to Mr. de Niceville (Butt. [nd. i. 122) 

 " specimens (of the dry-season form) taken in Lower Bengal (named indlstans) are 

 paler coloured both on the under and upperside than in those from the Sikkim 

 Himalayas. This variety {indlstans) is developed in the plains of N.-E. India, and 

 is most distinctly specialized in the district of Calcutta. It is found as far south 

 as Orissa, and as far north as Upper Assam, but in these localities it is less distinct, 

 specimens from Assam being almost if not quite inseparable from Sikkim examples." 



Of the illustrations on our Plate 63, of the wet-season brood of C. visala, fig. 1 

 represents a Sikkim male ; fig. la, the fore and hindwing of male, showing the 

 glandular patches ; figs. 1, b, c, a Calcutta female ; figs. 1, d, e, Calcutta males ; 

 and figs. 1, f, g, h, Nilgiri males. On Plate 64, representing the dry-season brood, 

 figs. 1, la, b, are Sikkim male and female (these being the types of the form named 

 Visala) ; figs. 1, c, d, are Calcutta male and female (the types of the form named 

 indistans) ; fig. 1, e, the larva and pupa (reproduced from Mr. de Mceville's figures 

 in Jouro. As. Soc. Beng. 1886, pi. 12), and figs. 1, f, g, h, are males and female from 

 the batch reared in Calcutta by Mr. de Niceville, in October, 1885, from eggs 

 deposited by a female of the previous wet-season brood, and which have been kindly 

 sent to me for examination ; fig. 1, i, is that of a Nilgiri male from Mr. Hampson's 

 Collection. 



Distribution. — Commencing on the north-east, specimens have been verified of 

 both sexes of the wet-season form from Sikkim, taken by Mr. Paul Mowis in May, 

 and a male from Buxa in Bhotan ; also of the dry-season form from the Sikkim Terai, 

 taken in September, October and December, and in the Runjit Valley, 1200 to 3500 

 feet, in October, in Col. Swinhoe's Collection. Mr. Elwes (Tr. Ent. Soc. Lond. 

 1888, 304) remarks that " Mr. de Niceville's experiments in breeding have thrown 

 some light on the seasonal forms of this species in Calcutta, but I cannot say to 

 what extent his conclusions are borne out in the different climate of Sikkim. Mr. 

 Otto Moller, however, has little doubt that the M. Visala is the dry- weather form, 

 and finds it commonly from the Terai up to about 5000 feet, at the end of the rains 

 and on to December. The ocellated form he takes at the same elevations from April 

 to September. I hardly think that the various broods will prove to be constantly
