broods, while in the northern limit of the species there is probably 
ut one. The eggs from which the worms are produced are laid oh 
the silk, upon which the young worms at first feed until they are 
about a third grown feeding the rest of the time on the kernels in¬ 
side o. the busks. Asa cotton insect it feeds, as its name indicates 
upon the boll or pod, first upon the tender substances of the calyx as 
it increases in size boring into and destroying the whole boll. ^ 
The moth is variable in depth of color and shading, but is usually 
of a pale clay yellow with a more or less distinct tint of olive green 
and marked with olive and rufous, with a blackish spot near the cem 
ter ot the wing and a dusky shade near the outer margin. The hind 
wings are a little paler, with a blackish outer border containing a 
light spot in the center. 8 
Remedies. The remedies for this insect must be chiefly preventive- 
especially in re ation to their attack on corn, as their work is gener^ 
■J out o f sight. Of these, early planting has been found advanta- 
geous, as late planted corn is usually the most injured. As thev pass 
the winter in the chrysalis state, fall plowing infested fields, will 
break up the earthen cells containing them, and thus mingling them 
with the loose dirt the winter rains and frost will kill them. 6 
Spec. Char. Larva— Length 1.50 inches; color varying from pale 
green to dark brown; when full grown, some being pale brown striped 
with darker brown others pale green striped with dark green. The 
stripes are a dorsal dark line bordered each side with light, then a 
subdorsal line darker than the dorsal, with the stripe along the stig¬ 
mata light; lower part the general ground color. On each segment 
aie eight shiny black piliferous spots, from which arise brown hairs. 
Ihe lour on the back of each segment are arranged in the form of a 
trapezoid, with the parallel sides transverse with the body, the short¬ 
est side towards the head. The two on each side are arranged about 
the stigmata, one above and a little anterior to the opening, and the 
other back and on a line with them. Head and legs brown ; cervical 
shield dark brown. There are a few short hairs scattered over the 
body besides those from the piliferous spots. 
Chrysalis. —Length, .80 of an inch. Color, light chesnut brown, the 
doisai line, stigmata and divisions of the segments darker. Form 
rather shm, an indentation on the back where the abdominal segments 
begin, the last four segments movable, two thorns at the extremity. 
Kiley m his description of this says, four thorns at the extremity, 
but alter carefully examining a number of bred specimens of the fall 
brood, as well as those taken from the cornfield, I fail to find more 
than two and no indications of any more. 
Moth. Expanse of wings, 1.50 inches. Ground color of fore wings a 
c ayey yellow tinged with light olive green, and marked with darker 
olive and dark brown or black. The usual marks faint; the subter- 
nnnal line usually the most distinct. The basal, t. a. and t. p. lines, 
a slightly darker olive than the ground color, with a few black scales 
on the veins and costa, in rubbed specimens the position of these 
lmes only indicated by the black scales. Orbicular of the same color 
as the wings, either bordered with olive and having a clear center, or 
bordered with black and green scales and a black point in the center. 
Keniform somewhat lunate, black with a violet tinge in the outer 
part. The subterminal space is usually a little darker than the rest
