Pergesa castanea, Moore, P. Z. S. 18/2, p. 567. 

 Sattara, June. 



8. Pergesa acteus. 



Sphinx acteus, Cram. Pap. Exot. iii. p. 93, pi. 248. f. A. 



Poona, January and February ; Belgaum ; Bombay. 



Feeds on different kinds of Caladium, also feeds on Sissiis ; larval 

 stage about two months ; those found feeding on Caladium were 

 light green, and those on Sissus were pink. 



9. Daphnis nerii. 



Spliinx nerii, Linn. Syst. Nat. i. 2, p. 7^S (1767). 



Poona, April and November ; Bombay, August to November. 



These are much darker and brighter-coloured than those found in 

 Sind ; the larvae in Sind were invariably found feeding on Oleander, 

 but in Poona they were usually found feeding on J'abernamontana 

 and Coronaria ; some hatched 2nd April cast their first skin the next 

 day, the second skin on the 7th, turned chrysalis on the 12th, and 

 emerged in their perfect state on the 25th and 26th idem. 



10. Chcerocampa nessus. 



Sphinx nessus, Drury, 111. Exot. Ins. ii. 46, pi. 27. f. 1. 



Belgaum. Bombay, September, October, and November, very 

 plentiful. I have often found numbers lying on the ground under 

 the electric light on Cumballa hill.

Sphinx alecto, Linn. Mus. Lud. Ulr. p. 357. 

 Poona, February and September; Bombay, August, September,

12. Chcerocampa celerio. 



Sphinx celerio, Linn. Syst. Nat. i. 2, p. 800 (1767). 



Poona, June to November ; Bombay. 



Has three or four bronds, one after the other ; the first lot of 

 larvae in June, in the height of the monsoon rains, became pupae in 

 14 and 15 days, and only remained in that stage about ten days ; but 

 the last lot, in September, are much slower in growth, and more 

 delicate : they feed for a month, and the perfect insect does not 

 emerge till the following June ; larvae feed on Caladium. 



13. Chcerocampa thyelia. 



Sphinx thyelia, Linn. Mus. Lud. Ulr. p. 360. 



Poona, June to November ; Bombay, August to November. 



The above notes apply to the transformation of this species also.
