THE PINK CORN-WORM. 11 
January 16, 1915, Mr. C. E. Smith collected in the field at Baton 
Rouge, La., and sent to the writer several cobs of corn in the husk. 
The cobs were poorly formed, most of them having few developed 
grains, and they showed old work of the corn stalk-borer (Diatraea 
saccharalis Fab.) and of the corn-ear worm. A number of adults of the 
rice weevil (Calandra oryza L.) were present in the husks, and adults 
of Cathartus gemellatus Duv. were abundant in the same situation. 
The pink corn-worm was found among the leaves of the husk, in 
the kernels, and in the cob itself. Larvze of various sizes were present, 
but were mostly nearly full-erown, judging from some that were 
observed in silken cocoons in all locations where larvee were observed. 
It was difficult in this case to estimate how much feeding had been 
done on the husks, kernels, and cobs by the Batrachedra larvee 
because of the injury by, and the presence of, other insects. Larvee 
of Cathartus gemellatus and of Sitotroga cerealella were also present 
and may have caused some injury. It seems, however, that a part 
of the silk and most of the small pellets are due to the work of the 
Batrachedra larve and that some of the cavities in the kernels were 
due to them. 
Messrs. Thos. H. Jones and C. E. Smith found the pink corn-worm 
Mm various sizes, some apparently full-grown, working on ears of 
sweet corn, in company with several other species. In some ears 
they were working where the husk was still green and in some cases 
where the husk had begun to dry. The larve followed attack by 
other insects, or where from some other cause a portion of the ear 
had become exposed as from injury by birds, and ‘nipping off”’ of 
the tips by a horse, etc. In many cases the ears in which they were 
working were in bad condition, being so injured as to be of little value. 
At Baton Rouge, La., on July 24, 1915, moths were placed in a jar 
containing yellow cornmeal with a piece of sponge moistened in 
sweetened water, the jar being placed in the insectary. The first 
moth, coming from eggs laid by moths placed in the jar at this date, 
was noted on September 30. The time taken for the development 
would indicate, when compared with the rate of growth on other 
substances, that cornmeal is not a particularly good food for the 
larve. It will be noted here that it was possible to rear this insect 
in cornmeal in experiments conducted at Washington. Another 
point should be made, namely, that infestation in Louisiana has not 
been anywhere near as severe as in Mississippi, and that most of the 
corn ears received from the latter State were in exceedingly bad 
condition. 
EARLIER RECORDS. 
From correspondents of the Bureau of Entomology we have had 
this species from Colquitt, Perry, and Atlanta, Ga., and New Orleans, 
La., in cotton bolls.
