THE ENTOMOLOGIST. Ill 



Record' (1864). The larva of Heliotbis 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. Ill, 

 and still again at p. 340. Tiie name of Leucania extranea 

 was given by Guenee 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. Liijf ; Mansell Street, Guernsey, April 

 19, 1875. 



[According to Guenee this species is found in France, 

 Austria, and Germany, in July and August. This profound
