Report on the spring' migration of 1908, W. Stone (Caiisinia, J908, No. 12, 

 J)}). .'i5-52). — The records of tlie spring niignitions of birds here rojtorted are 

 based on reports from 50 stations in New Jersey and Pennsylvania. 



[Bibliography for 1908] (Vassinia, J!)OS, No. 12, jrp. 55-6V, ) .—Fifty-seven 

 papers, larjj;ely relatins; to the birds of Pennsylvania, New Jersey, and Dela-

Animal parthenogenesis, L. Doncaster (Set. Prog. Twentieth Cent., 3 

 (1908), No. 9, pp. 40-52). — This brief review of the subject, accompanied by 

 references to the literature, is of particular interest to the entomologist. 



Sex determination and parthenogenesis in phylloxerans and aphids, T. H. 

 Morgan (Scicnee, n. scr., 29 (1909), No. 736, pp. 23Ji-237). — The phylloxera of 

 the hickories are said to offer exceptional opportunities for a study of sex de- 

 termination and i)arthenogenesis. In some species three generations can be 

 followed within the same gall, two parthenogenetic and one sexual. The 

 author has studied the cytological aspects of the life cycle of phylloxera and 

 here presents an account of the chromosomal changes that occur in connection 

 with sex determination. Phylloxera fallax and P. carycecauUs are the species 

 here considered. 



The Sphegoidea of Nebraska, H. S. Smith (Univ. [Nehr.] Studies, 8 (1908), 

 No. J/, pp. 323-JilO, pi. 1). — This is a paper based on material contained in the 

 collection of the University of Nebraska. Of the 200 species recorded 118 were

On some undescribed Scolytidae of economic importance from the Indian 

 Region, K. P. Stebbing (Indian Forest Mem., 1 (1908), No. 1, Zooh Set:, 

 pp. 12 ) . — The author describes 4 species of Sphserotrypes, 5 species of I'oly- 

 graphus, and 2 species of Dryocetes as new to science. Life history notes are 

 also given. 



Descriptions of new curculionid beetles of the tribe Anthonomini, W. D. 

 Pierce (Proc. U. S. Nat. Alas., 3 J, (1908), pp. 173-181).— In the investigations of 

 parasites of the boll weevil made by the Bureau of Entomology of this Depax't- 

 iiient, numerous new species of weevils have been met with. The author here 

 jiresents descriptions of 2 genera (Smicraulax and Mecynopyga) and 10 species 

 hitherto undescribed. These are accompanied by breeding and collecting 

 records. 



Contributions to the study of Japanese Aphididae, I and II, U. Okajima 

 (Bui. Col. Agr., Tokyo Imp. Univ., 8 (1908), No. 1, pp. 13-26, pis. .)).— The first 

 of these two articles is on the structure of the antennae of Aphididje, the second 

 upon 3 new species of Trichosiphum in .Japan, 



Remarks on Indian scale insects (Coccidae), III, E. E. Green (Mem. Dept. 

 Atjr. India, Ent. Ser., 2 (1908), No. 2, pp. 15-^6, pis. 3). — A paper in continua- 

 tion of a series previously noted (E. S. R., 12, pp. 369, 1067). The author 

 presents notes on the occurrence and food plants of a number of species, to- 

 gether with descrii)tions of 1 genus and IS species new to science. A catalogue 

 of all the species hitherto recorded from India is appended, in which 102 species 

 are listed, exclusive of varieties. 



Notes on Indian scale insects (Coccidae), H. M. Lefroy (Mem. Dept. Agr. 

 India, Ent. Ser., 2 (1908), No. 7, pp. 111-137, pis. 3, fig. i).— Notes on the food 

 l)lants are given and the life cycles of Monophlehus stebMngi octocaudata, 

 Iccrya minor, and Daetylopius saccharifolii are described in detail. The num- 

 bering of the species is that of Green's list, noted above. 



Gall midges of the goldenrod, E. P. Felt (Ottaica Nat., 22 (1909), No. 11, 

 pp. 2-'i'i-2Ji9). — This account includes a table of the galls supplemented by brief
