The head, without the mandibles, is truncate anteriorly and subtruncate 
posteriorly. The general color is rather dark honey-yellow, inclined to brown. 
The thoracic plate is pale honey-yellow, well divided at the suture and, while a 
little darker on the outer margin, is nearly uniform in color. The anal plate 
is very pale, scarcely darker than the joints. The three pairs of fore legs are 
rather long and prominent. The prolegs, with the anal legs, are also prominent 
but shorter. Observed under a strong lens the spiracles and piliferous tubercles 
are minute but distinct, and the pubescence, although sparse and of fine texture, 
is rather long, some hairs being nearly as long as the width of the body. 
The average length when extended is about 13 mm. and the greatest width 
about 1.5 mm. 
THE PUPA. 
PI. Ill, B, C. 
In general appearance the pupa resembles that of other cereal-feeding moths. 
The general color is pale yellow. The form is robust, and the arrangement of 
the segments is well shown in Plate III, B and C, the latter illustrating the 
ventral arrangement of the legs and wing pads. These latter extend nearly to 
the antepenultimate abdominal segment. The eyes, in fresh specimens, show 
merely as circular areas but when nearing transformation they become black. 
The antennal sheathes slightly overlap on the posterior margin. The best 
characters appear on the dorsum, the short median parallel elevated longi- 
tudinal lines evidently being characteristic, as they are nearly black and quite 
distinctly marked. The spiracles are small but distinct. The anal segment 
bears at the apex four processes, the anterior ones being in the nature of 
short spines. 
Naturally there is a difference in the proportions of the pupa of this species 
as in the adult, the length varying from 7.5 mm. to 9 mm. 
When about to transform the larva prepares a cocoon by joining 
together, by means of silken threads, a mass of the material on which 
it is feeding, as shown in Plate IY, A. An exposed cocoon is illus- 
trated in Plate IY, B. 
DISTRIBUTION. 
While Corcyra cephalonica is known to occur in portions of 
Europe, Asia, Africa, and southern and insular America, it is by no 
means truly cosmopolitan. Durrant and Beveridge (9) 1 record the 
Mediterranean region, India and Ceylon, the Cocos Keeling Islands, 
Christmas Island, the Kei Islands, western Sudan, Xyassaland, La 
Reunion, Para, Brazil, and Cuba and Grenada, West Indies. Rago- 
not (7) records Italy, the Ionian Islands, and the Seychelles. To 
this list may be added Porto Pico, Mexico, Hawaii, and Penn- 
sylvania. 
FOOD HABITS. 
According to the authors just mentioned the rice moth would ap- 
pear to be of eastern origin, introduced into Europe and elsewhere 
by the rice trade, and this is undoubtedly true. They further state
