Naphthalene possesses advantages ov^er carbon bisulphide in 

 protecting stored seed against attack by such insects as Bruchus 

 chinensis (cowpea weevil) and B. (juadrimaculatus (four-spotted bean 

 weevil), as it can be used repeatedly and is not explosive. It has 

 been found to be satisfactory when used at the rate of 1 lb. to 

 40 bushels of grain. In this case it was used in cloth bags, each 

 containing ^ lb. It seems probable that, when used at several times 

 that strength, such as 1 lb. or more to each bushel of grain confined 

 in tight receptacles for a few days, the insects in peas and beans 

 would be killed, and the injury which occurs after the grain is stored 

 would thus be entirely prevented. While 1 lb. of naphthalene to 40 

 bushels of grain is satisfactory for preventive purposes, the larger dose 

 of 1 lb. to 1 bushel, with the naphthalene in 1 lb. lots, should be tried- 

 Experiments would soon show how eftective this treatment would be, 

 and also the length of time necessary to accomplish the desired object. 

 At the end of this period, the large bags of naphthalene could be 

 replaced by the small ones. 



A species of Cryptorrhynchus similar to, but slightly smaller than, 

 that recentl^^ reported as attacking cassava [see this Reoiew, Ser. A, iii. 

 p. 504], is reported from St. Vincent, where it attacked the stems of 

 pole Lima beans planted from imported seed. This species has not 

 yet been investigated.
