This moth pertains to the genus Cerostoma of Latreille and the 
British entomologists, a genus belonging to the family Tineim, and 
intimately related to that to which the Palmer worm pertains—both 
genera having the feelers with a tuft of scales projecting forward 
like a beak, from the middle of which beak the slender terminal 
joint stands upwards like a little horn. The larvm of the two 
genera are also identical in their appearance and habits.. The 
genus Cerostoma is described as differing from that of CAatocAilus 
in having the wings narrower and rounded at their ends, differ- 
ences which are so slight as to be scarcely discernable on a com¬ 
parison of this species with the moth of the Palmer worm. The 
antennae, moreover, are directed forward instead of being turned 
backwards and lying upon the back; but this is a character which 
is liable to be deceptive except when observed in the living speci¬ 
men. The light color of the inner margin of the wings, however, 
and the lace-like cocoon of the pupa, leave no doubt that it is the 
genus Cerostoma to which our insect must be referred. Stephens 
(Illustrations, Haustellata, vol. iv. p. 341) says the spiral tongue 
in this genus is “shortish,” whilst Westwood (Humphrey’s British 
Moths, vol. ii. p. 245) gives it as “long and slender.” The lat¬ 
ter is certainly its character in our insect, where it is about equal 
to the antennae in length. Our species is closely allied to the C. 
porrectella, Lin., the worm of which Mr. Westwood found feed¬ 
ing upon buds of the White Pocket, a plant of the same family 
with the cabbage, and which forms an open-net work cocoon the 
same as our species. 
The worm of the Cabbage moth is nearly cylindrical in its form, rather thickest in 
the middle, .and slightly tapering towards each end. It is over a quarter of an inch 
long, measuring when full grown 0.35, and is the thickness of a coarse knitting 
needle. It is variable in its color, but is most commonly pale green, of the same hue 
as the cabbage leaf. Some are of a deeper tinge and others paler, varying to green¬ 
ish yellow or pale yellow. Often the hind part of the body is paler than the fere 
part. Frequently the head or the apical segment or both are pale yellow, the rest 
of the body being of the usual green hue. Individuals may sometimes be met with 
having the head dusky or black with dusky clouds. The neck is fre¬ 
quently tinged with red. Commonly a stripe along the middle of the 
back is more or less distinct, of a deeper green color, or blackish in 
places; and on each side of the back a similar stripe may be dis¬ 
cerned, whilst low down on each side a whitish stripe is sometimes 
apparent. With a magnifying glass Jbe body is perceived to be 
clothed with several short black hairs which proceed from minute
