SZ Captain T. Hutton’s Characters of 
Having now disposed of the Annuals, we have to consider the 
question of distinction with regard to what are commonly termed 
** Monthly worms.” 
3. Bompyx Cres, Hutton. 
Syn. Bombyx Mori, var., of Indian sericulturists. 
The “ Nestry,” and “ Madrassee” worm of Bengal. 
This is a much smaller species than either of the preceding, 
yielding seven or eight crops of silk in the year; the cocoon is 
small, of a beautiful bright yellow colour, and of a somewhat 
loose and flossy texture. It is said to thrive best in the summer 
months from June to October, and at other times is only kept up 
to preserve the stock. In hot weather it goes through all its 
changes from the egg to the cocoon in twenty-five days, but in 
the colder months it occupies thirty-five days. The worm is 
from 13 to 2 inches long, and is of a clear silvery or pearly hue, 
having a moist dewy appearance. The anal spine is short and 
truncated, and the dark lunar marks, which are so conspicu- 
ous on the fifth and eighth segments of the two annuals, are in 
this species wholly wanting. It is said never to yield white 
cocoons, but that dark worms occasionally appear in the brood. 
I suspect this to be the “¢ Pat minor’’ of Helfer and Royle. 
4, BoMByx FoRTUNATUS, Hutton. 
Syn. Bombyx Mori, var., of Indian sericulturists. 
The ‘“ Dasee” worm of Bengal. (PJ. XIX. fig. 3.) 
This is the smallest species of the whole, and is said to be 
hardy, but the yield of silk is uncertain; there are no dark 
worms among them, and they thrive best in the cold season, oc- 
cupying at that time from the egg to the cocoon about forty days, 
but in hot weather only thirty-three days. 
The silk is of a golden yellow, and the cocoon small ; it resem- 
bles that of B. Creesi in form and texture. When near maturity 
there is a very marked and perceptible difference between this 
species and all the others, the worm being of a bluish leaden-grey 
throughout; the ocelli or Junate marks on the fifth and eighth seg- 
ments are wanting, as in the last; the anterior segments are 
slightly intumescent and wrinkled; a short pale spine on the 
penultimate segment. The eggs are small, and pale straw colour, 
remaining so until within a day or two of hatching, when they 
become leaden-grey.
