848 EXPERIMENT STATION RECORD. 



Insect enemies of the beet root in the south of France, F. Picakd (Tie Agr. 

 ct Rurale, 3 (191^), Xo. Iff. pp. 390, 391). — A brief discussion of the more 

 important beet pests. 



Insect enemies of locusts and of noxious acridians in Russia. — I, Coleop- 

 terous enemies, I. A. I'obtchinsky (Trudy liiiiio Ent. [St. I'ctenh.l, 11 (1014), 

 No. 1, pp. 68, pis. 2, fifjs. 22; abs. in Rev. Appl. Ent., 2 (1914), Her. A, No. 7, 

 pp. 473-475). — In this paper the author deals at length with the beetles which 

 destroy the eggs of Orthoptera. IG belonging to the genus Mylabris and 3 to 

 the genus Epicauta. 



The pea thrips, Gaumont and Vuillet (Bui. »S'oc. Nat. Ayr. France, 74 (1914), 

 No. 2, pp. 168-173). — This article relates to FninklinieUa robii.stn (Thrips 

 pisivora) which is a source of considerable injurj' to peas in France. 



In 1913 this thrips was abundant on peas, beans, and sweet peas in the Aisne. 

 It is said to occur in abundance in the blossoms of trefoil at Bourg-la-Reine, De- 

 partment of Seine, in May, and individuals have been found in the blooms of 

 crown vetch and lucern at Beaune, Ajuya reptans at Chaumont-en-Vexin, and 

 Echalliuiii ciaterium at Marseille. Thus it appears that this thrips is very 

 widely distributed in Frame and that it can survive at le.'ist temporarily on 

 other plants than peas and beans. 



Maine aphids of the rose family, Enrrti M. Patch (lluine tSta. Bui. 233 

 (1914), PP- 253-280, pis. 3, figs. 6').- -This paper gives brief descriptive accounts 

 and drawings of those aphids found in Maine upon members of the rose family 

 (Rosacese). The most serious of the apple aphids has been previously noted 

 (E. S. R., 30, p. 548), but the plum aphids have not previously been worked up. 



The species considered are the woolly aphid of hawthorn leaf, Prociphilus 

 corrugatans on Juneberry (Amelanchier) and Crataegus; Schizoncura lanigcra, 

 Macrosiphutn cratwgi. Aphis aveiice, A. brevis, and A. halceri on Crataegus; Myzus 

 porosus on strawberry; Myzus cerasi, A. fiircaia n. sp., Myzus pcrsica', A. ccrasi- 

 foliw, and A. tuberoulata n. sp. on cherrj-; A. cerasifolice, A. prunorum, A. cardtii, 

 Phorodon humuli, and Hyalopterus arundinis on plum; S. lanigera on mountain 

 ash; S. lanigera, A. avencc, A. pomi, A. sorM, and M. persicw on apple; A. brevis 

 on Pyrus japonica; Macrosiphum rosce, M. solamfoUi, M. dirhodum, and Myzus 

 rosarum on roses; A. rubiphila n. sp., and Macrosiphum rubicoia on raspberry; 

 and A. spirwcola n. n., A. spinephila n. sp.. and Macrosiphum spircecola n. sp., 

 on Spiraea. 



Brief notes on aphid control and a list of the literature cited are included. 



The woolly apple aphis, A. C. Bakeb (U. S. Dept. Agr. Rpt. 101 (1915), pp. 

 55, pis. 15, figs. 3). — ^This is a report of studies of Eriosoma (Schizoneura) 

 lanigera commenced in the spring of 1912. 



In experiments conducted it was found that the species does not migrate to 

 Ribes as is the case with E. iilnd in Europe. The results of the author's ex- 

 periments did not agree with those of Dr. Patch (E. S. R.. 2S, p. 251), who 

 reports transferring from elm to apple the species which she considered as 

 E. americana, in that the species which he considered americana would not 

 feed upon apple; they did agree, however, in that the elm was proved to be 

 the winter host of E. lanigera, so that he credits her with having first dis- 

 covered that the woolly aphis migrates from the elm to the apple in the spring 

 and in the fall returns to the elm. The negative results obtained from experi- 

 ments with Ribes indicate that three species develop on elms, namely, E. ulmi, 

 americana, and lanigera. 



The subject is taken up under the headings of early history; name, in- 

 cluding synonymy ; methods of study ; forms of the species, including technical 

 descriptions ; and a detailed study of the structure, habits, etc., of the species, 

 including molts, digestive system, injuries, body fluids, muscles, movement,
