Descriptions of new Thysanoptera, J. D. Hood (Proc. Biol. Soc. Wash., 29 

 (1916), pp. 109-123, pi. 1). — Of the 11 species here described as new 8 are from 

 the United States. 



Feeding- habits of Sinea diadema, H. L. Pabkee (Ent. Neics, 27 (1916), No. 

 6, pp. 280, 281). — Tlarough its increasing abundance in the fields in summer and 

 its predacious habit this reduviid has become of economic importance. 



The potato tingid (Recaredus sp.), H. L. Dutt (Agr. Jour. Bihar and Ori.ssa 

 Undia], 2 (191Jf), Double Xo., pp. J6-^7).— This pest was first noticed about 

 four years ago attacking stored potatoes in cellars at Tunia in the Champaran 

 district. It does serious damage in the affected locality by sucking out the sap 

 and converting the tubers into mere hard lumps which can not be used for 

 either eating or seed purposes. Systematic, biologic, and economic data relating 

 to it are presented. 



Monograph of the North American species of Orthotylus (Hemiptera), 

 E. P. Van Duzee (Proc. Cal. Acad. ScL, J^. scr., 6 (1916), No. 5, pp. 87-128, 

 fig. 1). — Thirty-four species of this genus of capsids recorded from North 

 America are described, of which 24 are new. 



The Anoplura and Mallophaga of North American mammals, V. L. Kel- 

 logg and G. F. Fereis (Lcland Stanford Jr. Univ. Pubs., Univ. Ser., 1915, pp. 

 74, pis. 8, figs. 18). — The first part of this work deals with the Anoplura. A key 

 to the families, subfamilies, and genera is followed by descriptions of new 

 species and determinations of old species of Anoplura, the authors having had 

 at hand 22 species and 2 varieties. 8 species and both varieties being described 

 as new. The second part of the work presents descriptions of new species and 

 determinations of old species of Mallophaga, of which the authors had at hand 

 18 species, one of which is new. A mammalian host list of North American 

 Anoplura and Mallophaga is included. 



A catalogue and host list of the Anoplura, G. F. Feeeis (Proc. Cal. Acad. 

 ScL, If. scr., 6 (1916), No. 6, pp. 129-213). — A synonj'mic catalogue of the Ano- 

 plura (pp. 135-185) is followed by a systematic host list (pp. 186-204). 



Eighty-seven generations in a parthenogenetic pure line of Aphis avenae, 

 H. E. EwiNG (Biol. Bui., 31 (1916), No. 2, pp. 53-112, figs. 19).— A detailed re- 

 port of breeding investigations. The occurrence of pedogenesis is recorded, 

 and the effect of continued parthenogenetic reproduction on virility and metabo- 

 lism of a strain has been determined. The effects of temperature on growth, 

 size, reproduction, and dimorphism are also noted. 



A review of the Pterocommini, A. C. Baker (Canad. Ent., 48 (1916), No. 8, 

 pp. 280-289). 



Aphididse found on the apple in Britain and the description of a new species 

 from Africa, F. V. Theobald (Canad. Ent., 48 (1916), Nos. 5, pp. 169-177; 

 6, pp. 202-213, figs. 5; 7, pp. 233-242; 8, pp. 261-263, fig. i).— Eight species of 

 plant lice have been found at different times on the apple in Great Britain, 

 namely. Aphis pomi, A. kochii, Siphocoryne avence, Erisoma lanigera, A. cratmgi, 

 A. runiicis, Phorodon humuli, and A. nigra (oxyacantlKB) , the first four of 

 which are common. Aphis pomonella on tlie apple at Nairobi, British East 

 Africa, is described as new to science. 



A satisfactory method of rearing mealy bugs for use in parasite work, 

 E. J. Branigan (Mo. Bui. Com. Hort. Cal., 5 (1916), No. 8, pp. 304-306, figs. 

 2). — Considerable success has been met with in the rearing of mealy bugs on 

 potato sprouts, use having already been made of them in transporting enemies 

 of mealy bugs from Japan to California. 



A new fungus on the green scale, W. Nowell (Agr. Neios [Barbados], 15 

 (1916), No. 375, p. 302). — The green scale (Lecamum viride [Coccus viridis]) 

 78786°— No. 3—17 5
