NYMPHALTN^. (Group EUTHALIINA.) 117 



Catekpillak. — Chilopodiform. Head large, face broad, flattened in front. 

 Head and body above and beneath including the legs very sparsely covered with 

 extremely fine short hairs. Body armed on each side with ten horizontally-projected 

 slender fleshy branched- spines, these spines being situated on the 3rd to the 12th 

 segment, and each spine is numerously covered with both rather long and very 

 short extremely delicate spines decreasing in length to the tip, where they are 

 slightly stouter, and apparently rigid, the longest of these delicate spines being 

 laterally-disposed and interlace with the spines of the next segment. (Described 

 from a preserved Bombay specimen received from the late Dr. Leith.) Colour. 

 Head and body, and spines, pale green; with a light yellow dorsal line touched with 

 blue ; the spines fringed with yellow. 



Chrysalis. — Short, thick, broad across the middle ; with a conically-triangular 

 medio-dorsal keeled prominence ; anal end short and tubercular at apex ; thorax 

 tapering, head-piece ending in two short obtuse points ; suspended by the tail from 

 underside of a leaf. 



Habitat. — India; Ceylon; Burma; Malay Peninsula, etc. 



Distribution. — " This is the commonest and most widely spread species of the 

 group occurring in India. It is met with throughout the outer raiiges of the 

 Himalayas and in the plains, except in the desert tracts. It also occurs in Ceylon, 

 Burma, and the Malay Peninsula" (de Niceville, Butt. Ind. ii. 217). In the 

 Western Himalayas, the Rev. J. Hocking obtained it in the " Kangra District in 

 October; the larva feeding on mangoe " (P. Z. S. 1882, 239). Mr. W. Doherty 

 found it in the " Kali Valley, Kumaon, 2000 to 3000 feet elevation. Scarce " 

 (J. A. S. Beng. 1886, 124). " In Sikkim it is a common species in the low valleys 

 and Terai, where it is to be found all the year round. It is a variable species, the 

 dry-season forms being much lighter coloured than the wet-season forms, and the 

 white spots on the forewing in both sexes differing greatly in different specimens 

 in number and size" (de Niceville, Sikkim Gazetteer, 1894, 143). The late Mr. 

 W. S. Atkinson's collection contained specimens from the Himalayas, Khasias, and 

 Plains of Bengal. We possess males and females of both the wet and dry season 

 broods from the N.W. Himalaya, Deyra Dhoon, Darjiling, and Calcutta. Colonel C. 

 Swinhoe records it from the " Khasia Hills, and Cherra Punji" (Tr. Ent. Soc. 1893, 

 286). Mr. Wood-Mason records " sixty-two males and twenty females, taken in the 

 forests around Silcuri, Cachar, between end of May and beginning of August" 

 (J. A. S. Beng. 1887, 361). It is " very common in the neighbourhood of Calcutta, 

 and I have frequently bred the larva from mangoe ; the butterflies frequenting these 

 trees" (de Niceville, I.e. 217). Mr. W. C. Taylor found it "common at Khurda 

 in Orissa" (List, p. 6). Colonel Swinhoe records it as "common everywhere in 

 Bombay and the Dekkan, from October to May" (P. Z. S. 1885, 130). Also taken
