THE ENTOMOLOGIST. lll 
Record’ (1864). The larva of Heliothis armiger is only too 
well known, in the Western States of the Union, under the 
name of the “fall army-worm,” and is thus never con- 
founded with the true army-worm. My readers are further 
referred to the ‘American Entomologist and Botanist, article 
* Army-worm,” pp. 52, 53, and Leucania unipuncta, pp. 106, 
111, 328, and 340: some of the information contained in 
these papers is extremely interesting. I will give extracts :— 
“In the corner where we saw them thickest, being oppressed 
with famine behind and our entrenchment in front, they 
turned on and devoured each other, the larger eating the 
smaller, and sometimes two making a meal of the same 
unfortunate. I did not see them kill each other. It may be 
that the living attacked only those already dead. I saw live 
ones carrying about dead ones in their jaws, like a pig with 
an ear of corn, as though to avoid the others, and to enjoy 
their meal alone. There were a gallon or two of heads left 
in that corner.’"—(P. 52.) Again:—‘ The army-worms are 
destroying about all the pastures in this vicinity, but confine 
themselves chiefly to the red-top grass. They have also 
destroyed considerable corn. I have myself twenty acres of 
red-top; and unless they stop working upon it inside of two 
weeks it will be entirely ruined for hay.”—(P. 52.) The 
name of Leucania unipuncta, given by Haworth in 1803, is 
associated with the army-worm, p. 106, and again at p. 111, 
and still again at p. 340. ‘The name of Leucania extranea 
was given by Guenée in 1852; he makes no reference to 
Haworth, but observes that it somewhat resembles Heliothis 
armiger and H. peltiger; whence probably the error in 
confounding the two army-worms. I have described it, in 
error, in ‘ British Moths,’ p. 261, under the later name of 
Extranea, being quite unaware at the time of its identity with 
Noctua unipuncta of Haworth.—_ Edward Newman.] 
Agrotis crassa in Guernsey.—I have another species to 
add to our Guernsey list, the Agrotis crassa of Hiibner, two 
specimens of which I have taken in this island. I sent one 
of them to Mr. Doubleday, who has kindly returned it with 
this name.—W. A. Luff; Mansell Street, Guernsey, April 
19, 1875. 
[According to Guenée this species is found in France, 
Austria, and Germany, in July and August. This profound
