of which only the row along the spiracular line is conspicuous ; the spiracles are 
oval, shiny and white. Length 51 mm.” 
Pupa.— £i The pupa has the dorsal line of the thorax absolutely parallel to the 
longitudinal axis for two-thirds its length ; consequently the hinder part just before 
the margin is perpendicular to this parallel part, i.e. is raised suddenly though very 
slightly above the front margin of segment four, and the front end of this parallel 
dorsal line is at an angle, and a sharpish angle, with the front slope of the thorax ; 
the shoulder, too, is distinctly angled, the point where the lateral line of the head 
and segment two meet that of the wings—the front margins of segments nine and 
ten in the dorsal line—when looked at sideways show a minute peak overhanging 
the hiuder margins of segments eight and nine; the cremaster is distinctly bifid at 
the extremity, and has some shiny, very short, black suspensory hooks dorsally as 
well as at the extremity. There is a dorsal rugose black tip to the snout terminating 
the head, which snout is cylindrical in its apical half; there is no black line round 
the eyes, and there is a dark green-blue dorsal line, which is yellow on the thorax, 
as well as the supra-spiracular yellow line. Length 34 mm.” (T. R. Bell and de 
Niceville, Butt, of Kanara, J. Bombay N. H. Soc. 1900, 251.) 
Egg.—“ Single, on leaf. Pale yellowish-white, sharply pointed at each end, and 
attached by one point to the leaf. Larva, when emerged from the egg, is pale 
green, the head larger than any succeeding segment.” (Capt. A. M. Lang, 
Umballa, MS. Notes, Sept. 2nd, 1861.) 
Food-plants. — £fi We have found the larva of Croc-ale on several species of 
Cassia , all arboreal, such as C. fistula and Sumatrana , but never on the humble and 
ill-smelling C. Occident alls, the food-plant of C . Pyranthe. We have found it 
abundantly in the Kanara District of Bombay, at the end of the rainy season, and 
also in April.” (J. Davidson and E. H. Aitken, lx. 1890, 360.) 
Distribution, Habits, &c. —In the North-Western Himalaya Capt. A. M. Lang 
“ found the butterfly frequenting, the Cassia fistula, which is indigenous to the lower 
slopes of the outer ranges, 2,000 to 5,000 feet elevation, but an introduced plant in 
gardens in the plains of N. India” (Ent. Mo. Mag. 1864, 103). Mr. P. W. 
Mackinnon records C. Cascale and Catilla , as occurring commonly in Masuri, 
N.W. Himalaya, from July to October, and in Dehra Dun throughout the warmer 
months of the year ” (J. Bombay N. H. Soc. 1898, 586). Major J. VY. Yerbury 
obtained it in N.W. India, at “Hassan Abdal, 1,600 feet above sea level, in 
June; at Chittar, between Tret and Barracoo, Murree road, 2,500 to 5,000 feet, in 
October; and at Hurripur, in October” (Ann. Nat. Hist. 1888, 202). Air. W. 
Doherty obtained it at “ Bagheswar, Ranibagh, Jakula Kali Valley, from 1,000 to 
6,000 feet, in Kumaon ” (J. As. Soc. Bengal, 1886, 135). 
Capt. A. M. Lang, writing from Umballa, Sept. 2nd, 1861, says, “ C. alcmeone
