DiSTRiBDTiox AXD Habits.— " In the iSr.W. Himalayas and in Sikkim I have 



always met with this species near water. It occurs at Shillong in May ; Mr. H. M. 



Parish has taken it in the Chittagong Hill Tracts in jSTovember; Capt. C. T. 



Bingham has taken it in the Donat Range, Upper Tenasserim. It is not a rare 



species where it occurs, and has a very pretty soaring flight, and usually settles 



with wide outspread wings on the upper surface of a leaf " (de Xiceville, Butt. Ind. 



ii. 120). Capt. A. M. Lang records it as being found in the Western Himalayas, 



generally on the banks of streams (P. Z. S. 186-5, 495). Major H. B. Hellard 



obtained it at " Simla and Masuri, from June to October " (MS. Xotes). Mr. L. de 



Niceville says, " I have only seen it near water. Each insect seems to frequent a 



limited space, and flies backwards and forwards within this space, occasionally 



settling on overhanging bushes, &c., but starting off in pursuit, and doing battle 



with any intruder, especially one of its own species, that dares to invade its domain. 



It soon becomes shattered, and no wonder, considering its pugnacious temperament " 



(Indian Agric, January, 1880). Mr. W. Doherty took it in the " Sarju, Kali, and 



Gori Valleys, 2000 to 5500 feet elevation, Kumaon" (J. As. Soc. Bengal, 1886, 123). 



Mr. P. "W". Mackinnon, to whom Ave owe the discovery of the larva and pupa, of 



which we reproduce his pubHshed figures on our Plate 389, records it as " very 



common during the summer in and near Masuri, where it is probably triple-brooded, 



but is not found in the Dun. The larva feeds on the Siar, Debregeasia bicolor, Nat. 



Order JJrtkacese, on which I found it in August. The leaf of the plant is much 



crinkled, as also is the skin of the larva, so it is difficult to see the latter even in 



bright sunshine" (J. Bombay X. H. iS. 1895, 371). Mr. H. J. Elwes says that,
