his first edition of the Guide to the Study of Insects. He states on 
the authority of Mr. Saunders that the larva, of which he gives a brief 
description, feeds on the hollyhock in August. He also makes men- 
tion of Plusia larve figured by Glover in his work on insects injurious 
to the cotton plant, but as this work was never published, in the true 
sense of the word, it need not be further mentioned here. 
In the late Dr. Riley’s second Missouri Report (p. 112), published 
in L870, this species is briefly treated in connection with a discussion 
of Plusia brassice. He states that it occurs commonly on thistles 
and proposes the name of thistle Plusia. The larva is said to differ 
from the cabbage Plusia only in haying the sides of the head, the 
thoracic legs, a row of spots above the lateral light line, and a ring 
around the breathing pores, black. 
In the Canadian Entomologist (Vol. XIII, pp. 21-23) for February, 
1881, Mr. D. W. Coquillett, now of this office, published an article 
entitled, ‘*On the early stages of usta precationis Guenee.” Sub- 
sequently, in the same publication (Vol. XIV, p. 60), Mr. Coquillett 
calls attention to the wrong identification of the species, the insect 
which he had under observation being P. s/mplex and not precationis. 
The species is again referred to in connection with a consideration of 
Plusia simplex by My. Coquillett in the Eleventh Report of the State 
Entomologist of Illinois in 1882 (pp. 88-42). From studies made at that 
time of the larvee of these three species of Plusia, deductions were 
made that //usta simplex ditters from brassice only by the black 
rings around its breathing pores, and that both of these larve differ 
fom precationis by lacking the black stripes on each side of the head. 
Unfortunately, as the writer has previously observed, some examples 
of brassicxe also have these black rings about the breathing pores. 
No extended observations have been made on the life history of this 
species, but it is probable that it will be found to agree perfectly with 
P. brassice when it occurs in the same localities. Such individuals as 
were under observation by the writer transformed to pup in seven, 
eight, and eleven days, pupation beginning in three instances in early 
June, and in two in late June, the eleven-day period being passed in 
unseasonably cool weather. 
It should be added that there is in the National Museum a moth 
reared October 4, 1882, on Gerardia pedicularia (presumably in the 
District of Columbia), and of a Proctotrypid, bred from the cocoon of 
this species March 29 of the same year. 
The name of eyed-cabbage looper is proposed for this insect. 
REMEDIES. 
This species would yield to the same remedies as advised for the 
common cabbage looper, namely, Paris green, best applied in the form 
of a spray, but it is usually not abundant, and hand-picking would 
suffice on small patches of cabbage or other plants affected.
