It is to be expected that the several species of bean and pea weevils which occur in the West Indies will be found to attack beans and peas generally. At the present time B. chiiunsis is known to attack pigeon peas and cowpeas, and B. r/ua-lrimaculutus to attack pigeon peas. The use of naphthalene instead of car bon bisulphide as a protection for stored seed against the attacks of these insects , is indicated in the Agricultural N"ew$ in the article referred to above, and it would seem that this substance should prove a must useful insecticide foi such insects as the cowpea weevil and the four-spotted bean weevil. These insects are alike in their habit of infesting the glowing grain in the tield, and developing Successive broods in the stored seeds. This development r,m probably 1»' checked at once by the use of naphtha lene,but the point needs to proved by careful experimental trials. On reference to the article in the Agricultural Netos already referred to, it will lie seen that when used at the rate of 1 tt>. to 40 bushels of grain, naphthalene afforded a very satisfactory protection for stond corn. In this instance the naphthalene was used in cloth bags, each containing J-fl). It seems probable that,
