' Among the insect enemies of stored products which have been ob- served recently in this country, a small whitish larva or caterpillar of the moth Corcyra cephalonica Stainton (PL I) has attracted atten- tion by its injuries. It resembles somewhat the better-known fig moth {EpTiestia cautella Walk.). It has not been noted as a pest of importance, and has been given no common or English name. As it is somewhat widely reported as destructive to stored rice it may be called the rice moth. Beginning with October, 1911, complaints of damage by this insect were received from a firm manufactur- ing chocolate in western Pennsylvania, and a year later from an- other manufacturing firm in the same State, but the species was not positively identified until 1916. NATURE OF INJURY.
