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- 
seribe 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 ; 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; 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,
