Root Borer, Grub (on left) and Perfect Insect (on right). quite common in its occurrence in St. Kitta-Nevis, Antigua and Montserrat, wher^ it is often to be found hiding amongst the leaves of such plauts as castor and pigeon peas, which grow along the borders of cane fields. This adult insect has previously been kiinwn largely on account of its habit of feeding on the leaves of limes and otlier Cilrus plants. If the connexion between this weevil and the root borer grub is definitely established, it may prove to be a more serious pest than has been suspected. The fact that these beetles are fairly abundant would indicate that their larvae must have some food plant other than sugarcane, since, if this were the only food plant, the attacks would have been discovered before this time, while the relation between the weevil and the grub would have been sooner suspected. The methods of control sug- gested in the report for the root borer and the hardback grubs are the ."ame as those Fig. 12.

Crawford, Assist ant Curator, Division of Insects, United States National Museum, described and named Zalophothrix mirum when this useful parasite was found to be exerting a very material control over the black scale (sSaissetia nigra) on cotton in Barbados. In a note included in Descriptions of New Hymenoptera, No. 3 {Proceedings of the United States National Museum, Vol. 41, pp. 267-82), Mr. Crawford states that Z. mirum is a synonym of Lecaniobius cockerelli, Ashmead. This insect will therefore be called by the latter name, in future, in the publications of this Department, the name being followed by the words 'Zalophothrix mirum' placed in square brackets.
