88 LEPIDOPTERA INDICA. 



in considerable numbers have been flying over the trees of Cassia fistula during the 

 end of August. I captured many in my garden, and found the eggs and larvee in 

 all stages. The egg, laid singly, on leaf, is pale yellowish- white, sharply pointed at 

 each end. The largest larva found on Sept. 2nd was 2^ inches long, of a uniform 

 breadth throughout, except at the head and last segment ; colour deep grass-green, 

 darkest along the back, and shading slightly lighter towards the lateral stripe, 

 which is a creamy yellowish white ; the green is shagreened by transverse ridges of 

 points, their minute extremities being black ; botli the lateral stripe and the part of 

 the dark green occupying the space between it and the legs is glazed ; stigmata 

 scarcely perceptible, creamy-white, and lying partly in, partly below lateral stripe ; 

 abdomen very bright cream, almost white ; the abdominal and true legs of the same 

 colour and a shade deeper ; head grass-green, irrorated with minute black points ; 

 immediately above the lateral stripe, in large specimens, the irrorations become 

 larger black points, and form a more or less uninterrupted line of black points 

 distinguishable above the stripe. The larva feeds on the upper surface of the leaf, 

 generally lying along the midrib." (MS. Notes.) 



Col. C. Swinhoe records G. Grocale, " taken at Mhow, Central India, in July, 

 and Gatilla, common, from September to April" (P. Z. S. 1886, 432). Col. 

 Swinhoe also records taking " a single female in Karachi, in 1879, and another female 

 was taken in July, 1882 {id. I.e. 1884, 511), and in the District of Bombay and the 

 Deccan," he obtained Grocale at Poona, in June and October; Ahmednuggur, in 

 June ; Belgaum, September ; Bombay, August to November. The form named 

 Eeera having been taken at Belgaum in September, and at Poona in November and 

 December, and Catilla being " common all the year round; the larvae found feeding 

 on the Sumatran Cassia, length 1^ to 3 inches in the hot weather, and from 2|- to 

 3 inches in the rains; larval stage being from 18 to 22 days" (id. I.e. 1885, 140). 

 Messrs. J. Davidson and E. H. Aitken record it as being " found abundantly, in 

 the Kanara District of Bombay, at the beginning and end of the rainy season, and 

 also in April. We found the larva on several species of Cassia, all arboreal, such as 

 Ustula and Sumatrana. They refuse G. occidentalis — the food of C. Pyranthe. The 

 larvae are most plentiful in April, June, and September, but the butterfly may be 

 seen any month in the year" (J. Bombay N. H. Soc. 1890, 3G0 ; id. 1896, 570). 

 Mr. G. F. Hampson enumerates the forms Grocale, Catilla Gnoma, and Ilea, as 

 being found in the Nilgiris (J. As. S. Beng. 1888, 361). Mr. H. S. Ferguson 

 "found Grocale and Catilla in abundance together, in Travancore, in the drv- 

 "weather, in the low countiy, and up to 2,000 feet on the Hills " (J. Bombay N. H. S. 

 1891, 444). Mr. W. C. Taylor records it as "very common at Khorda, in Orissa" 

 (List, p. 1 4 (1888). Mr. L. de Niceville '' obtained it in tlie neighbourhood of Calcutta, 

 the larva feeding on Cassia fistula " (J. A. S. Beng. 1885, 50). Col. C. Swinhoe has
