Silk-producing Bombycide. 313 
5. Bompyx ArRACANENSIS, Hutton. 
Syn. Bombyx Mori, var., of Indian sericulturists. 
The Arracan worm. 
When first hatched, the Arracan worm is very small ; of a pale 
sandy-brown colour, and hairy, like all the others; anterior edge 
of the first segment whitish, or livid ash; head black. 
I succeeded only once, many years ago, in obtaining a few eggs 
of this species, through the kindness of Mr. Blechynden, secre- 
tary to the Agri-Horticultural Society of India, a gentleman 
whom I have uniformly found ready to assist in every useful 
inquiry. The worms produced from these eggs were very feeble, 
and, refusing to feed, were all dead by the evening. 
The cocoon is said to be larger than those of the Bengal 
monthly worms, and the silk strong and good. 
The worm is supposed to have been introduced from Burmah. 
6. Bomsyx Srnensts, Hutton. 
Syn. Bombyx Mori, var., of Indian sericulturists. 
The small Chinese monthly worm. 
Sina” and “ Cheena” of the Bengalis. 
The worm of this prolific species is considerably smaller than 
that of B. teator, and the cocoon partakes much of the same cha- 
racters, being sometimes white and sometimes bright yellow, with 
occasional cocoons of a beautiful faint greenish-white. The mark- 
ings of the mature insect are very different from those of the 
Boro-pooloo, and from all the others. 
Eggs received from Bengal began to hatch on the 26th of June ; 
head and pro-legs jet black and shining: the body hairy and 
pale brown, with minute anal horn. 
On the 30th of June these worms motlted, the head and pro- 
legs being black as at first ; the four anterior segments pale ashy, 
the second and third gibbous and wrinkled; the remainder 
mottled ashy-grey ; a short blunt conical spine on the penultimate 
segment. ‘There are also two longitudinal dorsal rows of minute 
round black dots, four on each segment, and giving out minute 
hairs; on the fifth segment are two semi-lunar brown marks, the 
horns of which point inwards, as in L. Mori; the anal tubercle 
with a few short cilia at the summit, and behind this, on the anal 
segment, are two minute tubercles placed close together like the 
sights on a gun, and behind them again lower down, and on the 
anal shield or valve, are two others ; stigmata black.
