April, '14] HINDS: BLACK WEEVIL CONTROL 203 



the sugar beet factory informed me that one man will cover 20 acres 

 in a day. Five Japs distributed the bran over 30 acres in 3 hours — 15 

 pounds of bran to the acre. One hundred pounds of bran poisoned with 

 Ij pounds of Paris green, is used to cover 7 acres. No sugar or salt is 

 added. About 1,500 acres of beets are under cultivation near the sugar 

 beet factory. 



Description of Larva. Length, when mature, from about 1| to 

 nearly 1| inches; of a sordid, whitish, color; no markings on body. 

 Thoracic shield brown with a whitish dorsal stripe. Spiracles black. 

 Tubercles dark brown, setse circled with white. Dark pulsating dorsal 

 vessel, conspicuous in some specimens. Thoracic feet pale brown; 

 prolegs concolorous. Head pale brownish almost concolorous with 

 body, the only marking being a conspicuous band of dark brown on 

 epicranium, bordering either side of clypeus and median suture, some- 

 what after the sides of the letter H; ocelli black; mouth-parts blackish. 



Status of the Insect. Porosagrotis delorata was described by 

 Smith^ from a single male specimen collected at High River, Alberta, 

 which locality is 101 miles, by rail, from Lethbridge. From a study 

 of the specimens which we have reared I am convinced that P. delorata 

 is Morrison's species (Agrotis) orthogonia, described from Glencoe, 

 Nebraska.^ A specimen which 1 recently examined in the collection 

 of Prof. T. N. Willing, of Saskatoon, Saskatchewan, and which had 

 been collected at Regina, Saskatchewan, on August 10, 1904, w^as 

 determined by Mr. F. H. Wolley-Dod as Porosagrotis orthogonia. In 

 the Canadian Entomologist, XL, 102, March, 1908, Sir G. F. Hampson 

 records a specimen under this latter name which was collected in 

 Alberta. 



Mr. Glenn W. Herrick: Was the poison mixed with dry bran? 



Mr. C. Gordon Hewitt: Enough w^ater was added to make it 

 easy to handle. 



President P. J. Parrott: The next paper is by Dr. W. E. Hinds 

 entitled "Reducing Insect Injury to Stored Corn." 



REDUCING INSECT INJURY TO STORED CORN 



By W. E. Hinds, Auburn, Alabama 



In economic value for the Southern States this problem is only 

 second in importance to that of controlling the IMexican cotton boll 

 weevil. The present interest in stored corn insect control is in some 

 measure an outgrowth of the fight that is being made for better farming
