THE RICE MOTH. 6 
honeybees and certain species of wasps. Indeed, it is most closely 
related to the lesser bee moth (Achroia grisella Fab.), a somewhat 
uncommon species in this country, but well known abroad. 
Corcyra cephalonica is extremely variable in size, specimens which 
were first reared from material received from western Pennsylvania 
being quite small, while individuals from later generations are much 
larger, and in some cases show markings on the forewings more dis- 
tinctly. A moth is shown in Plate I, A, with wings extended; the 
natural position at rest is shown in Plate I, B ; and the wing venation 
is illustrated in text figure 1. 
The following technical description is reprinted from Durrant 
and Beveridge : 
Antennae whitish fuscous ; basal joint with some darker fuscous scales. 
Head and Thorax very pale fuscous, sometimes whitish fuscous, or darker 
fuscous. Fore wings very pale fuscous, the veins more or less indicated by 
darker fuscous scaling, and with a tendency to suffusion over the whole wing, 
except along the dorsum which remains of the pale ground-color; in some 
specimens the darker markings are almost absent, in others there is a tendency 
to form two irregular transverse dark lines, one at the end of the cell, the 
other at about half the wing-length, with some dark shading toward the base ; 
a more or less distinct dark spot occurs on the margin at the end of each vein ; 
cilia pale fuscous, with some admixture of darker scales. Exp. al. 14-24 mm. 
Hind wings, $ fuscous ; $ shining whitish fuscous ; cilia with a slightly paler 
line at their base. Abdomen and Legs pale fuscous.

THE EGG. 
PI. II. 
The eggs have a pearly luster, are variable in shape, and have at one end 
usually a decided nipple, somewhat like that of certain fruits. The eggs are 
sufficiently large to be readily seen without the aid of a lens, and resemble 
somewhat those of the Mediterranean flour moth (Ephestia kuehniella Zell.). 
The exact dimensions have not been obtained. 
THE LARVA. 
PI. Ill, A. 
The larva when fully developed bears some resemblance to that of Plodia 
interpunctella. The sutures of the joints are somewhat more pronounced ; the 
general color varies from white to a dirty, slightly bluish gray with occasional 
faint greenish tints. This dirty appearance of the larvae is due to the dark 
material on which they feed and is especially evident in the immature stages. 
Larvae which have fed on rice are more nearly white than those which develop 
from cacao preparations.
