305 ANNUM. ADDRESS. Notes on the Mealy-Bugs of Economic Importance in Hawaii, ]\\ D.WII) l'. FULI.AWAY. (Presontod at tlu> mooting of December 7, 1922.) These notes have resuUed from a study of our common dactyl-opiine species ' made preparatory to handhng the material col-lected by H. T. Osborn in Mexico, which, during-the past few months, has been chiefly mealy-bug enemies. Mr. Osborn's in-vestigations in tliis field began primarily with the definite ])ur-l^ose of introducing and acclimatizing the coccinelHd beetle Jlypcraspis sUvestrii. observed by Koebele and Silvestri to be an important enemy of Pseitdococcus nipac in Mexico. The pursuit of this object led him gradually to widen the scope of his work, with the result that we have received from him nun^erous and sizable shipments of four species of coccinelHd beetles, in addi-tion to Hypcraspis sih'cstrii, and five or six internal parasites of mealy-bug species existing here. While the extent of Mr. Osborn's achievement in Mexico could scarcely be anticipated, the results amply justify a belief which I have held for some years : namely, that, in view of the comparative scarcity of some of the species existing here which are attacked by internal para-sites, it should be possible to ameliorate present conditions with regard to other species unchecked by internal parasites, by seek-ing out such enemies as exist and introducing them here. I believe all of the economically important mealy-bug species foimd here have been brought to the islands in the course of time with plants. In some cases, one or other of their enemies liave been brought with them, or have since been purposely introduced. ITidoubtedly the present situation with regard to mealy-bug infestations represents a great improvement over the Proc. Haw. Ent. Soc, V, No. 2, September, 192.3. ' Accordiiiji; to list rollowiiig. Eriucorcus araucariac uiul species of Afiterolecauium omitted from consideration, as Eriococcus and allies and AateroJecanium and allies are now viewed as separate subfamilies. The affinities of Pliyllococcu.i also being in question, that genus has not been inclu<led in the picseiit discussion either.
