Correspondents also note that the- oldest cacao beans are. as a rule, 
the most heavily infested. 
May 6, 1914, 10 moths of this- species- were placed in a rearing jar 
with cacao beans as food. One moth was still alive on May 27, but 
was found dead the following day, having lived 21 days without food. 
According to Dyar the tongue is completely absent in this moth, so 
it is unable to feed. No evidence of insect attack could be noted 
through the glass jar when examined on July 9, but when some of the 
beans, which had become moldy on account of the moist weather dur- 
ing this period, were opened, a mature larva and a cocoon contain- 
ing a pupa were found. Attack was confined chiefly to beans that 
already had been injured more or less. 
March 8, 1916, Dr. Carl Michel, United States Public Health Serv- 
ice, San Juan, P. E., furnished moths and pupae, the latter in webbed- 
up rice, and stated that the species infests warehouses in Porto Rico, 
that the eggs are laid in sacks of cereals, and that the developing larvae 
render the cereals unfit for human consumption. The merchants at 
San Juan claim that the rice is infested before it reaches that port 
and that nearly all of it is concentrated at New Orleans or Galveston 
for shipment. The claim is not made, however, although it is in- 
ferred, that the insect is shipped from the United States, but it 
seems more probable that the moth has been established in Porto Rico 
for a number of years. Agents of the Bureau of Entomology spent 
much time from 1908 to 1916 investigating insects injurious to rice 
and other stored products from New Orleans and Galveston, but they 
did not observe this insect at these or other ports. It may have been 
introduced recently through carelessness in vessels returning from 
Porto Rico containing foodstuffs on which it was able to subsist. On 
March 22 Dr. Michel sent additional specimens of larvae in infested 
rice. The larvae were all paler than were those reared from darker 
substances, such as chocolate and similar products, and as a result it 
was noted that the piliferous tubercles were plainly visible, whereas 
in the darker forms they were scarcely noticeable. September 12, 
1916, numerous larvae and some pupae of this species were received in 
rice from the same source. The correspondent stated that some of 
the moths had been breeding continuously since the previous Feb- 
ruary, and that the} 7 thrived at room temperatures. 
May 19, 1916, samples of rice infested by this species were again 
received, and on September 18 the Bureau of Chemistry reported 
that this specific shipment of rice was California grown, milled in 
San Francisco, and shipped via Panama Canal to New York City 
where it was held for about 30 days, and then reshipped to San Jaim, 
P. R., where upon its arrival the buyers rejected it because the 
market had declined, but not on account of " vermin," as the rice 
was apparently in sound condition. The rice was kept until October
