170 EXPERIMENT STATION RECORD. 



On some parasites of Coccidse, with descriptions of two new genera of Aphe- 

 lininee, L. < >. Howard I Proc. Ent. Soc. Washington, 4 {1898), No. 2, pp. 133-lS8,figs. .,').— 

 Besides describing two new species, the representatives of two new genera, namely, 

 Archenomus bicolor and Azotus marshali, notes on distribution are given. Prior to 

 18!U Aspidiotiphagus citrinus was unknown. In this country sinee then it lias been 

 taken from is species of scale insects and from many localities in the United States, 

 from Grenada, British West Indies; Portici, Italy; Punduloya, Kandy, Ceylon; 

 Hongkong and Amoy, China; Tamsui, Formosa; Yokohama, Japan ; Newlands, Cape 

 Colony; Adelaide, South Australia ; and Honolulu, Hawaii. A similar wide distribu- 

 tion has also been found lor Prospalia aiirantii, Aphelinns fuscipennis, A. mytilaspidis, 

 and A. diaspidis. trrhenophagus chionaspidis has also an almost universal distribu- 

 tion. As a new locality for A. diaspidi*, San Luis, Mexico, is noted, and for A.fusci- 

 pennis, Natal. 



A new Swedish egg parasite, C. Aurivillii s [Ent. Tidskr., 18 (1897); abs. in 

 Zool. Centbl., 5 (1898), No. 9, p. 295). — The author describes and figures a pteromalid 

 of the subfamily Tricbograinmatinse, for which he erects the genus Oophthora. I he 

 form seems to be closely related to Trichogramma of Westwood. It differs from 

 that form in its louder, nearly cylindrical, abdomen. The author thinks that Tricho- 

 gramma yreiiosa and T. minutw of Riley may possibly be properly considered as 

 belonging to the new genus. To the species he gives the name ( >senblidis. The speci- 

 mens emerge from the eggs of Senibli8 lularia. The male appears to be dimorphic. 

 Some appear without wings, others with wings. The latter closely resemble the 

 female. 



Notes on parasitic Hyrnenoptera, with descriptions of some new species, 

 G. Dimmock and W. H. Ashmead {Proc. Ent. Soc. Washington, 4 {1898), No. 2, pp. 

 148-171). — Brief notes by Dimmock on 70 species, and a description by Ashmead of 

 29 new species belonging to the genera as follows (the figures denoting the number 

 of species of the genus): Telonomus, Allotria, Eucyrtus, Habrocytus. Elachislns, 

 Cratotechus, Eulophus, Apanteles (6), Protopanteles (2), Microplitis, Aphidius, 

 Hypotherentes, Ischnoscopus, Mesochorus, Neoeryma, Sychnoportus, Phoeogenes, 

 Acrobela, and Asphragis. 



Parasitic worms on cultivated plants, E. Hknning {Landtmannen, 9 (1898), No. 

 19, pp. 299-303, ill.). 



Development of Platygaster, N. Kulagin (Ztscltr. Wiss. Zool., 63 {1897), pp. 193- 

 235, pis. : ; ahs. in .lour. Hoy. Micros. Soc. [London], 1S9S, No. 3, p. 73). — This para- 

 site of < 'ecidoiuvia, it is learned, occurs in a large number of dipterous, hemipterous, 

 and hymenopterons larva-. The larva of Platygaster lives on the fat body of the 

 host and pupates at the same time with it. The occurrence of one parasite in the 

 same host is not usually fatal; the occurrence of two is. 



Repressive measures against enemies of field crops, B. Frank {Eampfbuch 

 !/<!/<■» die Schadlinge unserer Feldfriichte. Berlin: Pare;/, 1S97, pp. 308, pis. 20, figs. 46; 

 ahs. in Zool. Centbl., 5 {1898), No. 5, p. 157). — This work will doubtless be of consider- 

 able use to many zoologists. It is written in a popular style, showing how to recog- 

 nize the animal and vegetable enemies of vegetables; treats of life histories, habits, 

 etc. The colored plates represent the eggs, larva?, and the character of ravages. 

 The book is divided into live parts, treating of the injuries to conifers, leguminous 

 plants, potatoes, corn, and beets. 



FOODS— ANIMAL PRODUCTION. 



Food preservatives, H. Leffmann [Pennsylvania Dept. Ayr. Bpt. 

 1897, I, pp. 535-548). — A number of food preservatives are described. 

 The effect upon the digestibility of starch of the following substances 

 was tested: Saccharin, beta-naphthol, formalin, artificial benzoic acid,
