by June 18. The moth is attracted by the electric light, and oc¬ 
curred in large numbers August 17, 1886, and again on the 19th,. 
20th, 21st, and 23d (at this last date numerous), and continuously 
thereafter until September 23, after which time it w r as not col¬ 
lected. The following spring it commenced to appear at the elec¬ 
tric light on the 19th May, and by the 23d was very abundant, 
continuing extremely common until June 3. The 6th and 7th 
June several moths -were taken, and additional examples later,— 
from three to eight at a time, until the 18th of that month, after 
■which only a single specimen occurred—captured July 14. It is 
thus clearly a two-brooded species, with a short spring interval of 
mischievous activity, its damage ceasing practically by the first of 
May. 
DESCRIPTION OF LARVA. 
A pale, much-striped cutworm, marked by an especially distinct 
lateral black stripe, and unusually stout, conspicuous black or 
yellowish bristles. General color yellowish gray, darkened by 
minute granulations. A pale dusky stigmatal band, bordered with 
darker, and above this (with a fine white line intervening) a 
prominent darker band less distinct on the thorax; then, next 
above, a brownish or reddish subdorsal band, bordered with white, 
most conspicuous on the thoracic segments. Dorsal space gray, 
with a broad moniliform dusky shade contained between the inner 
piliferous tubercles, this traversed by a rather broad continuous 
median white line. Substigmatal band mottled cream color, paler 
than stigmatal, and lighter also than the dusky venter. Prolegs- 
with a brown patch outside of bases, and jointed legs similarly 
colored. Cervical shield not well marked. 
Head opaque, with black granulations, darker than usual, very 
hairy, with the usual curved frontal black bands and darker retic¬ 
ulations on the sides. Antennal joints one, two, and three, white,, 
black, and brown, respectively. 
This larva attains a length of one inch. 
Described from ten specimens. 
The Glassy Cutworm. 
(Hcidena devastatrix , Boisd.) 
(Plate IV., fig. 3.) 
This is clearly a single-brooded species of rather long-continued 
larval life. The eggs are laid, and probably also hatched, in 
autumn, the species wintering in meadows and pastures as a young 
larva. Examples obtained May 29, in Peoria county, where they 
were reported as very destructive to corn, were still feeding July 
7, but pupated between July 15 and August 3. The imagos had 
emerged and died by September 21. A single pupa taken from 
blue grass and timothy pastures August 13, emerged as an adult
