elevation" (Ann. Nat. Hist. 1888, 142). Specimens from the Chumba Valley, 

 September, Narkunda, April, and Kujiar, April, are in Mr. J. H. Leech's 

 collection. Capt. A. M. Lang obtained it " at Kasauli in April and May, 

 floating from tree to tree. Also at Simla from May to November. Larva 

 found at Masnri, on April 21st, 1868, at 6500 feet elevation, feeding on 

 Berheris. Colour deep apple-green, shagTeened with paler minute points ; a pale 

 yellowish line above the feet; head small, hemispherical, yellowish-red, studded 

 with short pale black-tipt spines ; 2nd segment small, 3rd and 4th large, broad and 

 angular, the rest gradually diminishing to the end ; on each segment (except the 

 second) a transverse row of red spines, the lowest between the feet very small and 

 white tipt; the next lateral spines rather larger, forked with black points; the sub- 

 dorsal long and branched with numerous black-tipt spinelets, those on the 3rd, 4th, 

 6tb, 10th, and 11th much the longest; four or five red black-tipt spines at the anal 

 extremity; spiracles inconspicuous except on the second segment where they are 

 large and black ; prolegs pale yellowish. Moulted on the 25th, form entirely as 

 before, but colour deep yellow, with a broad lateral stripe of mottled blue-green. 

 Turned into a pendent pupa on the 28th. The imago emerged on May 

 15th " (MS. Notes). The larva has also been found by Eev. J. H. Hocking, in 

 Kangra, " feeding on Kusmtd, in August " (P. Z. S. 1882, 241). Mrs. S. Robson 

 records the life history of this species, as observed at Masuri (J. Bombay, N. H. S. 

 1894, 388). Mr. W. Doherty took it in the Upper Himalayan region, from Naini Tal, 

 6000 feet, and Askofc, 4500 feet, up to Dwah, nearly 10,000 feet elevation (J. A. S. 

 Beng. 1886, 125). We possess males of the dry and wet-season forms from General 

 Eamsay's Nepal collection, and also from Sikkim, both sexes of the dry-season form 

 from Simla, Masuri, and from Thundiani — taken in May by Major J, W. Yerbury. 

 " In Sikkim it is found in the forests at 2000 to 7000 feet elevation from April to 

 October, but is not common, and is difficult to take as it settles on high trees, and 

 only descends to the ground at long intervals" (H. J. Elwes, Tr. Bnt. Soc. 1888, 

 854). According to Mr. L. de Niceville " this species is at least double brooded, and 

 is found in Sikkim from April to October. It is also seasonably dimorphic ; the 

 form which occurs in the dry-season (spring) is quite typical opalina, while that found 

 in the wet-season is much darker, richer-coloured, and narrower banded " (Sikkim 

 Gaz. 1894, 141). Colonel C. Swinhoe records one specimen of the dry-season form 

 from Cherra Punji, and a series of the wet-season form from Shillong, in the Khasia 

 Hills (Tr. Ent. Soc. 1893, 283). Mr. W. Doherty took males of the wet-season 

 form in the Naga Hills, and others nearer to the typical ojxiUna in the Karen Hills, 

 Burma" (P. Z. S. 1891, 277). Capt. E. Y. Watson tooka single specimen in the 

 . Chin Hills, Burma, at 5000 feet elevation, in May (J. Bombay, N. H. S. 1897, 655).
