on the ‘‘silks,’’ mner husks, pith, and other parts of the cob; also in 
ears of field corn, eating into the kernels and cobs. At another time 
he observed it on a large woody twining bean vine, feeding on dying 
leaves and ripening pods, especially where there was an accumulation 
of webs and frass, or where other insects had been at work. Among 
other food plants he mentioned lantana, palm leaves, and the dead 
leaves of Pandanus, banana, and ‘‘various other plants.’’ On banana 
the larvee fed in the bunch on the dead or injured fruit and on the 
skin of the ripened fruit which they sometimes punctured, even eating 
into the fruit within. 
ASSOCIATED INSECTS. 
It has already been reported that this species usually follows the 
attack of the corn-ear worm (feliothis obsoleta Fab. [Pl. I]), which 
is true of most other forms of stored-grain insects in the South. At 
about the same time the rice weevil (Calandra oryza L.) enters the 
corn but does not seem to work with the same rapidity as does the 
species In question. Later, in all probability, another species which 
is quite common, the square-necked grain beetle (Cathartus gemellatus 
Duy.) enters the ears and causes considerable damage both in the 
field and in store. This same insect is often found associated with 
the pink corn-worm in cotton bolls, and breeds in the same. The rice 
weevil occasionally enters cotton bolls, especially when they are on the 
sround, but does not breed in them, merely entering them for shelter 
or for hibernation. The Angoumois grain moth (Sitotroga cerealella 
Zell.) also breeds in corn with the species under consideration but thus 
far has not been found in many instances. It was observed at Agri- 
cultural College, Miss., in a sending dated November 28. The sor- 
ghum midge (Contarinia sorghicola Coq.) was also found associated 
with the pmk corn-worm in sorghum seed from Brownsville, Tex., 
collected by A. K. McMillan, Nov. 9, 1909. A common moth ([ Nola] 
Nigetia sorghiella Riley) was found in the same lot with the sorghum 
midge and it is probable that in this case the pimk corn-worm fol- 
lowed attack of the Nigetia moth. 
Among other associated insects are the foreign grain beetle 
(Cathartus advena Walt.) and the coffee-bean weevil (Araecerus 
fasciculatus DeG.). The former is of comparatively little economic 
importance, feeding for the most part on stale grain, fruits, and other 
stored material, being naturally of a scavenging nature. Neverthe- 
less, it has been quite troublesome during the past two years. The 
latter attacks coffee beans, mace, dried figs, and various other dried 
articles of commerce, and is also found somewhat commonly in 
diseased cotton bolls. A small ortalid fly (Huzesta anonae Fab.) 
was reared January 29, 1914, from dasheen (Colocasia sp.) affected 
with the pinkcorn-worm. This Jast species is without doubt a natural 
feeder on dasheen, but no record of its habits is available.
