ANNUAL REPORT OF NEW YORK 
ARMY WORM. ITS BIBLIOGRAPHY. 
breaking up and sale of that collection, this specimen passed into 
the possession of Mr. Haworth, who, not doubting but that it 
had been captured in England, described it very briefly, in the 
year 1810, in his Lepidoptera Brittanica, page 174, naming it 
Noctua unipuncta or the White Speck, by which name it has ever 
since been referred to by English authors and collectors, save 
that a new generic name, Leucania, replaces that of Noctua. It 
appears to have been through inadvertency that Mr. Stephens 
changed this name to impuncta , when he came to describe the 
species in 1829, in his British Entomology, Hauatellata, vol. iii, 
p. 80. Later, in 1850, he refers to it under its original name, in 
the List of Lepidoptera in the British Museum, p. 289, it having 
now been ascertained that it was a North American and not a 
British insect. 
Guen£e appears to have overlooked this species of the English 
authors. In his valuable work on the Lepidoptera (vol. v, p. 77— 
Paris, 1852,) he regards it as a new species, naming it Leucania 
extranea. From him we learn that there are specimens of it in 
several of the Paris collections, whereby they know it to he a 
common insect in North America, Columbia and Brazil. He also 
states that a variety of it which is destitute of the white dot on 
the fore-wings, occurs in the East Indies, Java and Australia. I 
cannot but tliink, however, that this East India insect should be 
ranked as a distinct species from ours, as it differs in such a 
prominent character, and is so widely separated from it geogra¬ 
phically. 
An acknowledgment is due to the persons who furnished me 
with such materials as enabled me to ascertain the name of this 
species. Specimens of the moths bred from the army worm, were 
sent me last year from Hr. E. Jenkins, of Easton, Talbot Co., Mary¬ 
land, and the present year first from Dr. J. Bartlett of Pesotum, 
Champaign Co., Illinois; but in both instances, they came to hand 
in such a broken and soiled state that I could not confide in them 
as showing the true colors and markings of this moth. From 
these imperfect examples, however, I was able to obtain such 
characters as served to identify them with other very perfect 
specimens which had been received a few years since from Prof. 
D. S. Sheldon of Iowa College, and which had been already 
named in my collection. From them the following description of 
. the moth was also drawn.
