Byer, but because they have greater plenty of Asseen 
than Byer, and, moreover, trim and dress out plots 
of Asseen on purpose for the worms. The princi- 
pal difference between the above two species is, that 
the natives retain a part of the Jarroo cocoons 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 invariably 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, or perhaps 
one, two, or three days, a flight of males arrive, 
settle on the branches, and impregnate the females ; 
by the bye, the hill people calculate good or ill for- 
tune in proportion to the speedy or tardy arrival of 
the stranger males. These insects die as soon as the 
purposes of Nature are effected, and the females live 
only to produce the eggs on the branches of the 
trees, and then expire. In regard to the Bughy 
species, they all take flight, females as well as 
males, and hence the natives firmly believe that 
they are all males, though I cannot see any physical 
reason for supposing them so. I have frequently 
endeavoured to detain the males of the Jarroo spe- 
cies, and have kept them locked up in a box for that 
purpose; but whether they did not like to make 
free with their female relations, or from what other 
cau<;e I know not, but I never could obtain a breed 
in the domestic state, and the eff'orts of the male to 
escape were wonderful, and at last always eff'ectual.
