breeding in a feed warehouse in Honolulu in July. On July 10. 1909, 
it was captured at Kaena Point by Mr. Swezey. The latter part of 
the same month moths were found emerging from a package of 
cracked wheat obtained from a Honolulu grocers'. Mr. Swezey 
expressed the opinion that although the species is a European moth 
apparently not recorded at that time in the United States, it certainly 
must have reached Honolulu from the United States. 
The habits of the moth are well described by Barrett (2). He 
states that when disturbed in flight, unlike Ephestia and Plodia, it 
darts down in a zigzag and almost immediately comes to rest. To- 
ward evening the males run about, quivering their wings in a peculiar 
manner. The moth shows considerable skill in selecting for a resting 
place the projections of rough beams, to which, owing to its rough, 
blunt head and closely folded wings, it bears so close a resemblance 
that Barrett states he has taken specimens between his fingers before 
he could satisfy himself that they were not projecting splinters. 
This can be readily appreciated by reference to Plate I, B, which 
shows the moth at rest. The moth is peculiarly sluggish, even more 
so than those of the other genera. Barrett writes of this and of a 
related species (Ephestia) that they were being replenished con- 
stantly from imported dried fruits, since every cargo of fruit 
swarmed with the larva?, some of which died from change of climate 
and other causes, but many of which came to maturity. He states 
that it is obvious that places in which old " currants " have been 
stored are the most potent sources of infestation, the new fruit coming 
into harbor during the month of September when the moths are al- 
ready plentiful. He believed that the different species occurred in 
about equal numbers and was certain that they had formed a settle- 
ment from which it would be no easy task to expel them. 
CONTROL MEASURES. 
Warehouses and other structures in which the rice moth has be- 
come established should be cleansed thoroughly. Any bags which 
contain or have contained infested rice or other cereal, cacao beans, 
cocoa or similar material, or dried fruits should be fumigated; all 
corners, cracks, and crevices which may harbor the insect should be 
brushed out; and all refuse promptly destroyed by burning. The 
walls and floors then may be washed down with a soluble creosote 
disinfectant, or a solution of common salt. The brushes used should 
be stiff and strong, and every point should be reached so as to make 
the compartment perfectly clean. 
The machinery also should be cleaned thoroughly and the entire 
plant fumigated with hydrocyanic-acid gas. In small plants either 
carbon disulphid or sulphur dioxid may be employed for fumigation,
