For the past two years many complaints have been received from the cotton-growing regions of the South of injuries to cotton ])y a species of weevil known as ChaJcodermus miieus Boh. Attempts were made by several persons of experience to ascertain whether or not the insect really did injury to the bolls or squares of cotton after the manner of the Mexican cotton boll weevil, for which it was mistaken, always,.

On looking over the records of the Division of Entomology extending back into 1887 we find that the insect has a natural food plant in the cowpea, particularly when this plant escapes from cultivation or grows wild, and that it is capable of committing considerable injur}^ to both cultivated cowpea and beans. In September, 1903, we received pods of cowpea affected by this spe- cies, which permitted sufficient study to furnish a fairly good knowl- edge of all stages except the egg, and an approximate understanding of the insect's life history. DESCRIPTIVE. The adult Chalcodermus Fenem is one of the true weevils of the family Curculionid^, of shape similar to the well-known plum cur- culio, to which, indeed, it is not distantly related. The general color is black, with more or less pronounced bronzy tinge. The elytra are coarsely and strongly punctate, as is also the thorax, which is suddenly
