. Circular. Insects. 14. principal drawbacks to the cultivation of the pecan. Indeed, in many parts of the South it already divides that distinction with the husk- worm, so that it has been truthfully said that what the husk-worm leaves the weevil destroys. The beetle (fig. 13) is about the same size as the larger chestnut weevil, from which it may be distinguished by its much duller color a and by the relative lengths of the first and second antennal joints, the first joint being longer than the second in the pecan-infesting species. The larva differs from that of proboscideus in being decidedly yel- low, having the head bright red and wider than long. Its cervical plate also is darker. The pupa is similar to that of the larger chestnut weevil. The distribution extends from New York to the Gulf, and westward at least to Iowa. The life history of this wee- vil, as it occurs in the pecan in the South, is, so far as can be gathered from reports from Georgia and Texas and from laboratory experiments, very similar to that of the chestnut weevils. According to the ob- servations of Mr. H. A. Halbert, at Coleman, Tex., the female begins to deposit her eggs in August while the pecan is still immature, and the larva usually escapes from the nuts in the latter part of Septem- ber and in October; but most of them do not issue until the husks open, allowing the nuts to fall. In Georgia they have been found in the nuts as late as the middle of January. REMEDIES. The same care in the selection of the site for a pecan orchard is advised as in the case of chestnut culture, with this difference, that the grower should avoid planting in the vicinity of wild pecan and hick- ory of whatever kind. The entire crop, also, should be harvested or hogs should be turned in to devour what nuts are left. At Thorn a s- ville, Ga., Mr. Wilmon Newell observed in 190-1 that where swine and chickens had had access to a pecan grove, the ground was well rooted and scratched up and there was less loss
