308 Captain T. Hutton’s Characters of 
whether dark or white, appeared to be healthy; still they were 
not worse than their congeners, and eventually spun better co- 
coons, being, although not so large, much more stuffed with silk. 
Between these worms and those from Cashmere stock there is not 
a shade of difference, both being B. Mori. 
Imago.—In the moth the ground colour of the wings is a dull 
ashy white; sometimes they are entirely ashy, without any 
lines or other markings, while some have only two short parallel 
lines on the fore-wings near the centre of the costal margin. In 
others there are lines as below described, but no colours. These 
are from the white worm as now cultivated. 
The appearance of moths produced from black worms ap- 
proximates more to the wild B. Huttoni, both in colour and in 
markings. 
In these the ground of the wings is still ashy, and the male, as 
usual, is smaller than the female, having the shaft of the antenne 
white, with dusky black plumes; eyes black; body and ground 
of wings ashy-white, suffused with a pale brown tinge; near the 
basal angle of the fore-wing are two parallel lunate lines, the horns 
of which point inwards and rest upon the anterior and posterior 
margins; between these lines darkish brown, in some instances 
blending them into a brown band, in others the lines are clear 
and distinct; about the middle of the costal margin, at a little 
distance within the wing, are two very short parallel lines slightly 
curved in the opposite direction to the basal ones; these, how- 
ever, are sometimes absent; across the wing, from the anterior to 
the posterior margin, are two partially parallel submarginal lines 
at a little distance apart, the inner one being a slight curve and 
the outer one taking a bend or lunate sweep near the exterior 
and posterior angle; these lines are sometimes distinct and clear 
on the ashy ground, at others they are blended into a dark-brown 
band by the deep suffusion of the space between them. Fore- 
wing strongly falcate in both sexes; the hind-wing is rounded on 
the exterior margin ; abdominal margin folded down as in Ocinara, 
with one blackish spot about the middle; from the anterior to the 
abdominal margin are two subparallel lines through the dise of 
the wing, curving parallel to the outer margin, sometimes distinct, 
at others blended by the suffusion of the inclosed space with brown. 
The female is much the same, but there is in both sexes the greatest 
variety in the markings, which is, I think, a clear indication that 
the insect is not in a natural condition or sound state of health. 
The under-side dull ashy, with the dark lines and bands visible, 
as above. The male often exhibits ashy wings, with brown bands,
