The following paragraph is taken from tliis rei^ort : — 'The larva of a weevil determined as ^ sj^enffleri was found eating the bark from the tap-roots of orange _ stock in a nursery near Rio Piedras. The adult insect is common througliout the island not only on citrus stock, but on nearly all kinds of fruit trees. Aliandful of air-slaked lime at the foot of the tree deters the female from entering the ground to deposit her eggs at that jioint. Hand picking will probalily be found necessary to keep this pest in check for the few ; Specimens of tlie golden weevil of St, Vincent, which Las been determined as Biajinp,'.? spe>i;//( ri, were sent from the head oftjce of the Imiierial Department of Agriculture to Mr. Barrett, who has compared them with specimens of ^j'Civ/hri and concludes that they are the same.

The fact that this is now known to be a serious pest to citrus plants lends interest to the following descrijition of methods used to cajiture the adult "weevils ;— A large sheet of oil-cloth is attached on two sides to j>oles which serve as handles. From one of the remaining sides a slit is made to the centre, and this sheet is held under the orange cjr other tree, the trunk or stem of the tree standing in the slit. The tree is then jarred or gently shaken, whereupon the w-eevils fall down and are caught iii the oil cloth. They are then brushed off into a bucket containing kerosene oil and water.
