Captain T. Hutton's Notes on Indian Lepidoptera. 51 



Sp. 12. P. Sarpedon. 



Is one of the commonest, but not the least beautiful of our 

 butterflies ; it appears early in May, and is found till the end of 

 the rains in September, It usually frequents the top of oak trees, 

 where it flits about with a jumping or jerking flight, and is some- 

 what difiicult to capture from its quickness, and the height at 

 which it keeps. It is figured by Cramer (plate 122, D E), and 

 stated to be from China and Amboyna. 



Sp. 13. P. Cloanthus, Westwood. 



Is very common in fine warm weather, flitting with great 

 rapidity over the tops of the forest trees. It usually selects some 

 lofty oak, over the summit of which it continues to dance with a 

 jerking flight like that of P. Sarpedon, until its domain is invaded 

 by another individual, when a rapid chase round and round the 

 tree takes place ; one while they dart away from the tree down 

 the side of the steep mountain, but ever and anon return to the 

 favourite tree, until one is fairly driven ofl^, when the other 

 resumes its dance as before. It is difficult to capture, from its 

 high and rapid flight. It appears in the end of April, and con- 

 tinues throughout the summer. It is most nearly allied to the 

 foregoing, but has tails to the posterior wings. It is figured in 

 Westwood's beautiful work the " Arcana Entomologica." 



These are all the species of this genus with which I am as yet 

 acquainted as inhabitants of these hills, but should such like com- 

 munications be acceptable, I shall be very happy occasionally to 

 record any facts that may come to my knowledge. 



P.S. Since writing the above, it has occurred to me that I am 

 wrong in saying we have no other species of Papilio, as there 

 is certainly one, and probably two others. One seems to be very 

 closely allied to, if not identical with, P. Arcturus, but there are 

 some points of difference which make me hesitate to pronounce 

 them identical ; this one is very common in the Dhoon, and in 

 warm glens in the hills, during the latter part of the summer or 

 rainy season ; the other species or variety differs in having no 

 tail to the blue patch on the posterior wings, — the patch being a 

 mere large spot, and the under surface has red lunules also. In 

 P. Arcturus, a yellow crescent spot is represented by Westwood 

 at the eye spot of the posterior wings, which neither of my species 

 possesses.
