Aside from the sample of wheat infested by this insect receive 
during October, 1882, from St. Johns, III., it was found to have 
done considerable damage in the vicinity of Carbondale, by Mr. Joi 
Martin. 
In this case the wheat was attacked in the shock and the depre. 
dations were carried on during the time it was in stack, and whi!- 
in store, damaging the crop from one-fourth to one-third. 
Some of this grain I saw during April of the present year, bm 
could get no trace of other ravages among farmers north of 8 
Johns or south of Carbondale. 
DESCRIPTION OF THE MOTH. 
The adult insect has been so carefully described by Dr. T. )], 
Harris (Injurious Insects, id Ed., p. 506), that I shall copy hi> 
description in full: 
•‘The wings expand a little more than half an inch. The bean 
is smooth, and not tufted. The antennae are thread-like, with dis¬ 
tinctly marked joints. 
“The feelers are long, and curved upwards; the terminal joints 
naked, acute, and blackish near the tip; the second or middle joint 
rather shorter and thicker, hairy beneath, and blackish on the out¬ 
side; the basal joint very short and hairy. 
The tongue makes several spiral turns, and when extended, is 
about half the length of the antenme. The body and fore wings are 
of that tint of pale brownish-gray which the French call coffee-ami- 
milk color, and have the lustre of satin. 
“The fore wings are long and narrow, and are pointed at the 
end; together with their fringes, they are more or less sprinkled 
with blackish dots, especially near the tips. 
The hind wings are blackish, with a leaden lustre; they are nar¬ 
row, and very suddenly obliquely contracted to a point at^the tips; 
they are entirely surrounded with a blackish fringe, which is wider 
on the inner margin than the wing itself; they are folded length¬ 
wise, when at rest, beneath the upper wings. 
“The fore legs are blackish, and the liindermost legs are fringed 
with long hairs on the inner side.” 
DESCRIPTION OF THE LARVA. 
When first hatched, the larva, or caterpillar, although not thicker 
than a hair, immediately burrows its way into the kernel. 
When full-grown, it is about one-fifth of an inch in length, rather 
robust, gradually tapering posteriorly from the second segment. 
Head brown, the lateral margins light, as is also the region of 
the ocelli; the anterior margin a little darker. The mandibles are 
strong, bisetose, brown, with the inner margins nearly brown. 
I hey are quadri-dentate, the lower tooth being the larger. From 
this the teeth gradually decrease in size, the uppermost being the 
smallest. The other mouth parts and antennae are brown; the 
latter are short, three-jointed, terminating with a bristle.
