 Dept. Agric, Washington, D.C., Farmers' Bull. 983, September 

 1918, 24 pp., 24 figs. ' [Received 24th March 1919.] 



The species dealt with in this bulletin are : — Bruchus fisorum, L. 

 (pea weevil), which in one province of Canada alone has caused damage 

 to the extent of over £200,000 in a single year, B. obtectus, Say (bean 

 weevil), B. chinensis, L. (cowpea weevil), B. quadrimaculatus, F. 

 (four-spotted bean weevil), B. nifimanus, Boh. (broad-bean weevil), 

 B. lentis, Boh. (lentil weevil) and Spermophagus pectoralis, Say (Mexi- 

 can bean weevil). The usual remedies to prevent loss in storage 

 due to weevils are given, namely, the planting of sound seed, clean 

 culture, immediate harvesting and shelling of the seed, fumigation 

 with carbon bisulphide or carbon tetrachloride, treatment with 

 heat or cold, cold storage, storage with dust or air-slaked lime, and 

 occasional examination of stored seeds to guard against subsequent 

 re-infestation.

and D. famelicus. The usual methods of control are recommended
