be a serious enemy of the wild tliorny Acacia, whicli is prevalent on tlie higher 

 veld of Matabeleland, and iu some seasons attains the proportions of a veritable 

 plague in and around Bulawayo. 



The wax moth, T. B. Fletcher {Agr. Jour. India, 6 (1911), No. 4, pp. 

 S99-404, pl. !)■ — Notes on the life history of the wax or bee moth (Galleria 

 mellonella) as recorded at the Pusa insectary are included in this general ac- 

 count. 



Codling moth control, G. Quinn (Jour. Dept. Agr. So. Aust., 15 {1911), 

 No. 3, pp. 227-235). — A report of tests of the comparative value of several 

 brands of lead arsenate, all of which proved satisfactory. 



Notes on the larvae of Toxorhynchites immisericors, C. A. Paiva (Rec. 

 Indian Mus., 5 {1910), No. 3, pp. 187-190) .—The author reports that in the 

 course of 1 night more than 100 Stegomyia larvae were destroyed by 3 larvae 

 of T. inunisericors. When confined to small receptacles of water these car- 

 nivorous larvae will feed upon any mosquito larvae without discrimination, ex- 

 cept that apparently they do not begin to eat one another until other supplies 

 are running short. Since the yellow fever mosquito is very common in vessels 

 about Calcutta, the part played by T. immisericors in its destruction is of 

 considerable importance. 



A monograph of the anopheline mosquitoes of India, S. P. James and W. G. 

 LiSTON {Calcutta, 1911, 2. ed., rev. and enl., pp. VIII+128, pis. 32, figs. 17; rev. 

 in Nature [London], 87 {1911), No. 2190, p. 511). — A second rewritten and en- 

 larged edition of this monograph. 



Part 1 (pp. 1-5S) consists of a general account of mosquitoes, including a 

 list of the described or named species of the anophelines of India, and instruc- 

 tions for the collection, mounting, and examination of anopheline mosquitoes 

 and their larvae, and the classification and identification of Indian anophelines. 

 Part 2 (pp. 59-128) presents systematic descriptions of the anopheline mos- 

 quitoes found in India. 



The life history of the Phlebotomus, P. J. Maeett {Jour. Boy. Army Med. 

 Corps, 17 {1911), No. 1, pp. 13-29, pl. 1). — This subject, a preliminary account 

 of which has been previously noted (E. S. R., 25, p. 56), is taken up under the 

 following headings : Breeding experiments, life history, egg, larva, pupa, imago, 

 preventive measures for breeding, and preventive measures for lowering the 

 incidence of fever. 



Life histories of Syrphidse, II, C. L. Metcalf {Ohio Nat., 12 {1911), No. 

 1, pp. 397-405, figs. 18).— In this second pai^er (E. S. R., 25, p. 360), the author 

 deals with Paragus Mcolor and P. tibialis. 



Observations of P. Mcolor indicate that there are 2 distinct generations 

 annually, one appearing in the spring on dates varying from the middle of May 

 to the middle of June, or a little later in different parts of Ohio; the second 

 appearing in August and possibly later. Both species were found to be para- 

 sitized by a small ichneumonid {Bassus sp.), which oviposits through the skin 

 of the larvae. 



Fruit and pumpkin flies, E. E. Geeen {Trop. Agr. and Mag. Ceylon Agr. 

 Soc, 37 {1911), No. 3, pp. 240-242, fig. i).— The author reports having found 6
