structure, classiticatioii, etc. The main part of the work gives a brief discus- 

 siou of insects of general interest to the forester and then deals with the 

 subject under the headings of 19 of the more important trees attacked. Colored 

 plates are appended. 



A text-book of medical entomology, W. S. Patton and F. W. Cragg {London, 

 Madras, and Calcutta, 1913, pp. XXXIV-{-76S, i)ls. 89, figs. 5).— The successive 

 chapters of this work, several of which are divided into sections, take up the 

 subject as follows: (1) Introduction (pp. 1-7); (2) anatomy and physiology 

 of blood-sucking Diptera, general structure, and the internal structures (pp. 

 8-150) ; (3) the Orthorrapha-Nematocera and Orthorrapha-Brachycera (pp. 

 151-308); (4) the Cyclorrhapha and Pupipara (pp. 309-433; (5) the Sipho- 

 naptera or fleas (pp. 434-477) ; (6) the Khynchota or bugs (pp. 478-526) ; 

 (7) the Anoplura or lice (pp. 527-564) ; (8) the Ixodidse or ticks (pp. 565-680) ; 

 (9) mites (pp. 681-697) ; (10) the Pentastomida and Eucopepoda (pp. 698- 

 710) ; (11) laboratory technique (pp. 711-728) ; and (12) the relation of 

 Arthropoda to their parasites (pp. 729-745). A complete subject mdex Is 

 included. 



A contribution to exact biology, A. Handlirsch (Sitzher. K. Akad. Wiss. 

 [Tienna], Math. Xatui-w. Kl., 122 (1913), I, Xo. 3, pp. 361-W, flffS. 5).— The 

 first part of this paper (pp. 362-396) deals with the relation of the meta- 

 morphosis of insects to their distribution in climatic zones. 



Entomological research committee report for 1912—13 {Colon. Rpis., Ann. 

 [Gt. Brit.], No. 781 (1914), pp. 10).— A rei>ort of the work of the committee 

 since October, 1912. 



[Entomological investigations in Ontario], L. Caesae and A. W. B.\xee 

 (Ann. Rpt. Ontario Agr. Col. and Expt. Farm, 38 (1912), pp. 26-^8).— Black- 

 leaf 40 when combined with lime-sulphur and applied to apple trees just before 

 the buds burst or shortly after the aphid eggs hatched gave excellent results, 

 almost every aphid being destroyed. It was found that spraying with lime- 

 sulphur mixture on April 25, nearly 2 weeks before the buds burst, and in 

 May as they were bursting both gave almost perfect results. 



Injuries in a Spy orchard were found to have been caused by the young 

 nymphs of the hemipterous species Lijgidea mendax, Paracalacoris colon, and 

 Xeurocolpus nuhilus. The damage is done by the nymphs which uuncture and 

 suck the fruit, leaves, and twigs after the blossoms fall. 



A mixture consisting of 4 lbs. of arsenate of lead to 40 gal. of water sweetened 

 with 1 gal. or tnore of molasses was the most effective in combating the rose 

 chafer of any yet tested. The closely allied species Rhagoletis fausta was found 

 to be associated in some districts with the cherry fruit fly in damaging Mont- 

 morency cherries. 



Tests of arsenite of zinc on the codling moth and potato beetle at Guelph 

 gave as good results as arsenate of lead. 



Report of the entomologist, D. T. Fullaway (Haicaii Sta. Rpt. 1913, pp. 

 18-21). — This brief report of the work of the year includes a list of 60 insect 

 forms, representing 9 orders, collected during the course of a trip to Laysan 

 Island In December-January; a list of insects injurious to vegetables in 

 Hawaii ; and a brief discussion of the present status of work with the Mediter- 

 ranean fruit fly. 



The insects and other galls of plants in Europe and the Mediterranean 

 Basin, C. Houard (Lcs Zooc6cidics dcs Plantes <VEurope et du Bassin de la 

 MMUerranee. Paris, 1913, vol. 3, pp. 1249-1560, pis. 4, figs. 202).— This supple- 

 ment to the work previously noted (E. S. R., 22, p. 657) deals with the subject 

 under the headings of the various plant families concerned. Bibliographical, 

 zoological, and botanical indexes are included.
