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



seen in dozens in the same field at Raj pore, and elsewhere in the 

 Dhoon during the months of August and September ; nor are they 

 uncommon in the glens of these mountains. They are subject to 

 great variety in the size of the white spots which compose the 

 band on the posterior wings, as well as in the size and colour of 

 the lunules on the under side. It is figured by Cramer (plate 

 141, B), and stated to occur in China, on the coast of Coromandel, 

 and in Bengal. It is found also at Saugor, in Central India, and 

 I have received it from Madras. Mr. Westwood mentions in his 

 " Arcana Entomologica," that Colonel Hearsey had observed 

 P. Pammon and P. PoJytes chasing each other con amove, and that 

 this fact partially confirms the statement of Boisduval as to their 

 specific identity. Boisduval's supposition, however, is decidedly 

 incorrect, for I have repeatedly taken the males and females of the 

 two species ; besides which, the fact of the one chasing the other 

 could furnish no evidence, since I took at Neemuch a fine specimen 

 of a male Euplcea Plexippus actually in co'ilu with Euplcea Chry- 

 sippiis, and yet there can be no doubt whatever of the distinctness 

 of these as species. It may so happen that in some seasons, the 

 females, from particular causes, are scarce, and the males, burning 

 with fierce desire, may not improbably give chase to and even 

 couple with closely allied species, but this fact is no moi'e conclu- 

 sive evidence of identity of species, than the same act between the 

 ass and the mare would be ; or between the linnet and the 

 canary. It merely shows that nearly allied species may, under 

 certain circumstances, couple together for the purpose of satisfy- 

 ing their desires, but we have no proof of the female becoming 

 prolific from such intercourse, nor even if we had, could it furnish 

 more evidence than that we derive from the breeding of the horse 

 with the ass. 



Sp. 10. P. Glycerion, Gray. 



This very delicate and beautiful species is figured in West- 

 wood's "Arcana Entomologica;" it is rather rare with us, and I 

 have never seen it on the wing. Mr. Westwood's figure is taken 

 from a specimen captured at or near Simla. 



Sp. 11. P. Agestor. 



Is described by Mr. G. R. Gray as from Sumatra, but West- 

 wood's figure is from a specimen taken in India. It is one of the 

 earliest of the genus, being found in woody situations in April 

 and May, dancing lightly over the tops of low bushes and trees, 

 with a sailing kind of flight, gliding along without moving the 

 wings. It is by no means rare at Mussooree.
