The ocelli are white, six in number, arranged in the form of an 
elongate letter C, with the space enclosed varying from very dark- 
brown to nearly black. 
On the head, body and legs are sparsely-placed white, setaceous 
hairs; those on the head, first and last segments, and legs, are 
rather long. On segments two to twelve, inclusive, these hairs are 
less prominent, being placed in two transverse rows, those of the 
anterior row being much the shorter. On the first segment the 
hairs of both rows are equal; on the thirteenth segment, they are 
also equal, but, from the form of the segment, they are placed in 
a circular position. 
The body, with the exception of the spiracles, is White, smooth, 
and densely covered with minute, erect spinules, which can only be 
seen ,under a powerful glass. Traces of brown patches appear, in 
some examples, on the ‘dorsal surface of the first segment. Spira- 
cles, dorsal hooks, and minute terminal hooks on the _ pro-legs, 
brown. 
The legs are rather large at base, but taper rapidly, each termi- 
nating in a small hook. 
The pro-legs, ten in number, are small, wart-like, and terminate 
in two or three minute, robust hooks. (Curtis, in “Farm Insects,”’ 
p. 812, says that they terminate in a complete coronet of hooked 
spinules, but this is certainly an error.) 
DESCRIPTION OF THE PUPA. 
This is a little over one-fifth of an inch in length, the anterior 
extremity being obtuse, the posterior more acute, and surrounded 
by a ring of sparsely-set sete. 
Head, thorax and wing-pads dark, the abdomen lighter-brown, 
the wings nearly reaching the posterior extremity. Hyes in mature 
pup distinctly visible, and black. 
On the abdomen are rows of set, placed as follows: a double 
row on the margin, above the spiracles, placed in pairs; just below 
and close to the spiracles, a single row, one on each segment; each 
side of the middle hne of the body, another double row, the outer 
being placed on the posterior, the inner on the anterior part of the 
segment. 
On the inner side of the breast are a few scattered fei and on 
the neck two long, slender, conspicuous bristles. 
HABITS OF THE MOTH. 
The moth is nocturnal, and double-brooded under ordinary condi- 
tions, but a high temperature so actively hastens the transformations 
that the number of broods and time of appearance is somewhat 
variable. 
Dr. T. W. Harris, who bred the moths for three years in succes- 
sion, says that they appeared in considerable numbers in June and 
August, which is probably about the time the broods normally ap- 
pear. But infested wheat kept in the laboratory since October,
