great extent the trouble that had previoush^ been experienced. Our 

 correspondent believed that this statement would apply to the larger 

 mills, at least, of his locality. November 20, a correspondent at Balls 

 Ferry, Shasta County, Cal., reported this flour pest in that vicinity. 

 This appears to be a new locality in California, although the species is 

 rather more widely distributed there than in any other State of the 

 Union. 



January 28, 1902, the president of a flour companj^at San Francisco, 

 Cal., wrote in regard to the Mediterranean flour moth in that city. In 

 putting up breakfast cereals his firm had been serioush^ annoyed by the 

 eggs and larva? of the moth developing several weeks from the time of 

 packing. He said that the food material in question could be exposed to 

 a temperature of 212^ F. or thereabouts without serious damage. J une 

 30 a merchant miller, of Detroit, Mich. , sent this species in flour from a 

 mill in that city. He was anxious to obtain information in regard to 

 the use of hydrocyanic-acid gas, as the insurance companies refused to 

 grant permission for the use of bisulphid of carbon as a f umigant. Two 

 years earlier it was reported that one mill in Detroit was infested by 

 this insect, and it was surmised that the present invasion was due to 

 the introduction of wheat or secondhand bags from the Northwest, with 

 little doubt from Milwaukee and Minneapolis, where this species as 

 just reported is now known to be present in great numbers. It is now 

 said that nearly all the mills in those two cities are completely over- 

 run with this pest. 



THE ANGOUMOIS GRAIN MOTH IN 1901. 



In spite of the emplojanent of precautionary as well as remedial 

 measures that have been generally used against the Angoumois grain 

 moth {Sitotroga cerealella Zell.) in the more northern States in which 

 it is found, it continues to be injurious year by year, and it seems to 

 be as troublesome now as ever, if, indeed, not more so. The follow- 

 ing notes are extracts from correspondence during the year 1901. In 

 nearly every instance specimens of the insect accompanied the letters. 



February 8 we received word from the Larrowe Milling Companj^, 

 New York City, that this species was a general pest throughout New 

 Jersey and eastern Pennsylvania. 



On the 2Tth of the same month Mr. James R. Kirby, Smiths 

 Grove, Ky., wrote that the farmers of that vicinity were seriously 

 troubled by this species. 



March 4 Mr. William J. Haverly. Los Angeles, Cal., complained 

 of injury to the seeds of tield corn. 



September 28 Mr. Horace L. Dil worth reported this species as 

 doing great damage to wheat in the neigh))orhood of Centerville, Del.
