THE TUSSEH SILKWORM MOTH. 121 



every respect perfectly distinct from the insect of 

 the Palma Christi, the latter being different in size, 

 much less cultivated, and fed in houses as regularly 

 as the mulberry worm. I shall not proceed to de- 

 scribe it, as the species is not at all included in Dr 

 Roxburgh's questions. 



' The Jarroo cocoons alluded to above, are so 

 called from being produced in the coldest month of 

 the year, say January ; the Bughy being about a 

 month before them. The Jarroo are likewise an- 

 nual, and the history of them is nearly the same as 

 that of the Bughy j they are however different, I 

 am assured. The Jarroo will eat the Byer leaf if 

 he cannot get the Asseen, but he will always pre- 

 fer the latter, and produce a better cocoon when fed 

 on it. His silk is more of a dull colour than that of 

 the Bughy, which latter worm the hill people put 

 on the Asseen alone, not because it prefers it to the 

 Byer, but because they have greater plenty of As- 

 seen than Byer, and, moreover, trim and dress out 

 plots of Asseen on purpose for the worms. The 

 principal difference between the above two species 

 is, that the natives retain a part of the Jarroo co- 

 coons for seed j these they hang out on the Asseen 

 trees when the proper season of the moth arrives ; 

 when the moths come out, the male insects invari- 

 ably all fly away, but the females remain on the 

 trees. These are not impregnated by the males 

 bred along with them, but, in ten or twelve hours,
