326 Captain T. Hutton’s Characters of 
silk, if not superior, yet certainly equal, to that of B. Mori, 
[? B. textor, or B. Croesi, probably]. The cocoon shows the 
finest filament, and has very much silky lustre. Itis exceedingly 
smooth to the touch, and very different from the cocoon of the 
mulberry moth. The worm lives on the Pipul tree (Ficus 
religiosa).” 
It seems to have been entirely overlooked that Mr. Hugon in 
Cachar found his worms on “ the Bur-tree (Ficus Indica),” and 
that “in appearance, colour and size,” they were very like the 
mulberry worm; while Major Jenkins in Assam found his on an 
allied, but still a different tree, “ the Pipul (Ficus religiosa),” and 
the cocoon was “ very different from that of the mulberry moth.” 
Is it not quite possible that there may be two distinct species, the 
Deo-mooga of Cachar, and the Joree of Assam? 
What renders the uncertainty still greater is the fact that Mr. 
Hugon himself “ was unable to determine whether the Joree and 
Deo-mooga were the same, and was inclined, from the colour of 
the cocoons and the slight observations he was able to make on 
the latter, to think them distinct.” My own opinion, judging 
from what has been advanced, and from the fact that the cocoons 
are said to be less even than those of the Dasee (B. fortunatus), 
is, that neither the one nor the other belongs to Bombya, but will 
be found to be species of the allied genus Ocinara, an opinion 
supported in some measure by the nature of the food, these insects 
feeding on two species of Ficus, just as our two mountain species 
at Mussooree are confined to the Ficus venosa. 
Genus Ocinara, Walker. 
The insects of this genus, although in some respects allied to 
Bombyx, show likewise in the larva state a strong approach to the 
Geometre, being characterized by knotty and dry bud-like ex- 
crescences, which, with the rigid attitude assumed when at rest, 
give the insect the appearance of a withered twig or piece of dry 
stick. In those discovered at Mussooree the larvee appear to. be 
almost entirely night-feeders, seldom moving during the day 
from the position they have taken up, which is usually at the 
end of a thin twig, along which they lie stretched out immovable, 
and to which they are so much assimilated, both in colour and 
ruggedness of appearance, as easily to pass unnoticed. 
1. Octnara Moorer, Hutton, 
The larva of this species feeds on the Ficus venosa, and is found 
at Mussooree at an elevation of about 5,400 feet ; it spins a small
