LEPIDOPTERA 1NDICA. 
Chrysalis. —Greenish-grey ; thorax and anterio-dorsnm slightly arched; head- 
piece obtusely pointed in front. (Described from Davidson’s figures.) 
Habitat.— W. and E. Himalayas ; Continental India ; Assam ; Silhet; Burma ; 
Tenasserim; Siam; Malay Peninsula, etc. 
Dry-season Variety. —Occasionally a variety of the male of the dry-season form 
occurs in which the markings of the upperside are much paler yellowish-ochreous, 
the discoidal streak and discal bands on both wings are very broad and less defined, 
the lower end of the discoidal streak being confluent between the medians with the 
lower discal band; in one example the subapical band covers the entire apex and is 
also confluent with the lower band ; the intervening ground-colour is thus much 
restricted and is of an obscure brownish-black. On the underside the ground-colour 
is much paler, the bands and strigse indistinctly defined. An example of this 
variety, from Maungbhoom, Bengal, is in our possession ; one from Ooty, Nilgiris, 
in Colonel Swinhoe’s collection, and one from Sikkim, taken in March, by Otto 
Moller, in Mr. W. Rothschild’s collection. 
Distribution. —Mr. W. Doherty records taking it in Kumaon, at Ranibagh, the 
Terai, and the Ramganga, Kali, and Gorra Valleys; common at from 1000 to 
4000 feet elevation (J. A. Soc. Bengal, 1886, 125). We possess specimens of the 
wet-season form from Sikkim and Bhotan, taken by Mr. G. C. Dudgeon, and of the 
dry-season form, males from Nepal, taken by the late General G. Ramsay; Sikkim, 
taken in March, a male variety from Maungbhoom, Bengal, a female from Calcutta, 
both sexes from Kanara, Malabar, and from the Nilgiris, also from Moulraain, 
Tounghoo, Burma, and a female from Yemma Choung, taken in February by Colonel 
C. H. E. Adamson. Mr. L. de Niceville records the wet-season form from N.E. 
and S. India, and the dry-season form from Sikkim, Assam, Silhet, Malda, Orissa, 
Gangam, Nilgiris and Tre van drum, also from Chittagong and Upper Tenasserim. 
The dry form (plagiosa) taken in Sikkim in December, and typical Hordonia 
and intermediate forms from the spring to the autumn ; typical jplagiosa 
taken in Calcutta in February only; in Orissa, Mr. W. C. Taylor 
has taken jplagiosa in February and March, and Mr. J. L. Sherwill in the 
Jorehat District, Assam, in March” (Butt. Ind. 79). “ In Sikkim, it is a common 
species throughout the year, at low elevations. It is seasonally dimorphic, true 
Hordonia being the rains form, jplagiosa occurring in the dry-season ” (de Niceville, 
Sikkim Gaz. 1894, 136). Lieut. E. Y. Watson, during the Chin-Lushai Expedition, 
obtained typical Hordonia at Pauk from September to December, and single 
specimens in February and March. Specimens transitional to jplagiosa at 
Pauk and Tilin in November, and at Tilin from December to April. 
Plagiosa being taken at Tilin in March and April, and a single specimen 
in January ” (J. Bombay N. H. S. 1891, 37). The type specimens of jplagiosa were
