to those of the granary weevil, and in habits and life history these two 
species do not materially differ, except in that the rice weevil may often 
be found in the field remote from the granary, and in the extreme South 
and in the Tropics lays it eggs in standing grain. 
The rice weevil feeds upon the grain of rice, wheat, particularly the 
soft varieties, maize, barley, rye, hulled oats, buckwheat, chick- “peas, 
and the cultivated varieties of sorghum known as Kafir, or Je erusalem 
corn, ete., and the adult beetles, when abundant in stonehaat and 
groceries, invade boxes of crackers, cakes, and other breadstufts, bar- 
rels of flour and bags of meal. 
THE GRAIN MOTHS. 
THE ANGOUMOIS GRAIN MOTH (Sitotroga cerealella O1.). 
This moth received its name from the province of Angoumois, France, 
where it is known to have been injurious since the year 1736. In ie 
country, where it is familiarly but incorrectly called “fly weevil,” it is 
said to have been recog- 
nized as early as 1728. 
From the seat of its 
Supposed introduction, 
in North Carolina and 
Virginia, this moth has 
Spread to neighboring 
States in the South, 
where it does incalcula- 
ble damage, and to the 
southern portions of the 
Northern States, where 
it is less injurious. Al-

side view; d, pupa; e, moth; f, same, side view (original). distributed as the true 
grain weevils, 1t is rapidly increasing its range, and as it attacks grain 
in the field, even as far north as central Pennsylvania, as well as in 
the bin, is even a more serious pest in the localities in which it has 
become established than the weevils. It infests all the cereals, as well 
as ‘buckwheat and the chick-pea, product of the Tropics. It has been 
estimated that in six months grain infested by this moth loses 40 per 
cent in weight and 75 per cent of farinaceous matter. 
The adult insect resembles somewhat a clothes moth, for which 
indeed it is often mistaken. It is light grayish brown in color, more 
or less lined and spotted with black, and measures across the expanded 
fore-wings about half an inch (see fig. 2). The hind-wings are bordered 
with a long, delicate fringe. 
The moth deposits its eggs in standing grain and in the bin, singly 
and in clusters of from 20 to 30. The eggs, shown, much enlarged, in 
the illustration, are white when first laid, but soon turn red and hatch
