The general ground color is ashy finely specked . and . mottled 
with dusky, sometimes with a greenish or yellowish tinge. A 
yellow median line margined with blackish, very distinct upon the 
cervical shield, fairly evident upon the anterior segments, I 
especially the thoracic, but becoming obsolete posteriorly. A sim¬ 
ilar subdorsal line, upon which rest the subdorsal triangular i 
black spots. These spots, limited to the anterior part of each.seg- 
ment, are wanting on the thoracic segments, (rarely faintly indi¬ 
cated on the third,) and also on the two posterior segments, : 
although sometimes faintly apparent on the first of these. One or ‘ 
two of the posterior pairs rarely connected transversely by their 
posterior ends so as to form an irregular semicircle. The oblique 
stigmatal dashes are confined to the same segments and the same 
part of each segment as the subdorsal spots. These are some¬ 
times margined by a dusky shade, thus forming a wavy stigmatal 
band. The anal plate may bear a square brownish patch (trav¬ 
ersed by the dorsal line) between the two yellow subdorsal lines 
and beneath this a triangular black area, with the apex down¬ 
ward. 
The head is yellow, much reticulate with brown, with two heavy 
brown longitudinal bands upon each side of'the middle, narrowing 
forward and embracing between them the immaculate triangular 
frontal area. Two much narrower and less definite longitudinal 
brown lines upon each side of the head, with the upper ocelli 
between them. Under side of head with a dusky shade inclosing 
a pale area. Mouth parts pale, except the tips of the mandibles. 
Spiracular spots bordered below by yellow or flesh-colored 
patches, sometimes obscured by dusky, occasionally extended to 
form a substigmatal line. . 
The species is seemingly single-brooded, and matures early, most 
of our larvae finishing their growth in April and early May. 
The Spotted Cutworm. 
(Agrotis c-nigrum, Linn.) 
(Plate IV., fig. 1.) 
This species seems to be two-brooded, as already surmised by 
Coquillet and French, imagos of the first brood appearing in May 
and early in June, and those of the second, late in July and in 
August. For example, larvae which had hibernated, found abun¬ 
dant in Urbana in April, 1887, commenced to pupate on the 23d of 
that month, but still occurred May 6 in diminished numbers, of 
various sizes, from half an inch in length to full grown. 
An imago evidently of this brood emerged May 10 from a pupa t 
obtained in Southern Illinois, and another, from the central part of 
the State, yielded the imago May 29. Ten larvae taken from 
cabbage July 16, 1884, entered the earth for pupation July 25, 
and emerged as adults August 15 to 19.- Another imago of this!
