NOXIOUS AND OTHER INSECTS 
OF THE 
STATE OF NEW YORK.

INSECTS INFESTING GRAIN CROPS 
(continued.) 
C. Angoumois moth, Butalis cercalella, Olivier. (Lepidoptera. Tineidai.) 
Plate 1, fig. 2. 
In the bins of granaries and storehouses, in particular kernels of the grain, a smooth white 
worm whioh consumes all the flour inside of the kernel without injuring the external shell; 
passing its pupa state in the kernel, and coming abroad in May and again in November; a 
tawny dull yellowish gray moth having its fore wings oommonly sprinkled with a few black 
dots, its width half an inoh across its spread wings. 
This insect, one of the most destructive to wheat, barley, oats 
and Indian corn, in France, was long ago introduced into the 
southern United States, where it has become fully naturalized. 
From thence it is frequently brought into New York in cargoes 
of grain, but our climate appears to be too cold for it here to 
thrive and establish itself. 
In the museum of the State Agricultural Society, this moth 
made its appearance ten years ago, in the specimens of wheat 
preserved in glass bottles, multiplying itself in every bottle in 
which it occurred, until the contents were ruined. As these 
bottles were usually well stopped with cork and some of them 
also sealed with wax, it was a mystery how this insect gained 
an entrance to one after another of them, as it appeared to. 
The description of this moth in its different states which I 
here present, was drawn up from the examinations made at that 
Dme. The account which I give of its habits and economy and
