554 EXPERIMENT STATION RECORD. 



Entomolog'ical notes, C. Fullkr (Natal Ayr. Jour., 11 {1908), No. 2, pp. 

 'ii 1-196). — Brief notes are given on army worms, fruit-fly parasites, and San 

 Jose scale. 



Description of insects and their work. Insecticides, H. A. Surface {Zool. 

 Jitil. Penn. Dept. Agr.. 5 (1908), No. 12, pp. 361-^/2-;).— Descriptive notes are 

 given together with remedies for the common insect pests of fruits, garden crops, 

 live stock, and household articles. 



Notes on insect pests (Jour. Bd. Agr. [London], 15 (1908), No. 1, pp. 

 .'lO-Jfl). — In combating cockroaches good results should be expected from the use 

 of pyretbrum, poisoned baits, and traps. Brief statements are made regarding 

 the habits and means of combating eelworms, springtails, mites on gooseberries, 

 and Otiorbyncbus. 



Life histories and larval habits of the tiger beetles, Y. E. Shelford (Jour. 

 Linn. Soc. [London], Zool., 30 (1908), No. 197, pp. 157-184, pis. //).— The author 

 discusses suitable methods for rearing and studying larvae of tiger beetles. De- 

 tailed notes are given on the life history of Cicindela purpurea, C. formosa, 

 C. Irirticonis, and other species. The eggs are laid in the spring or midsummer 

 according to the species. The larvae hibernate in the second or third stage of 

 development and pupate the following June or during the second summer. The 

 interval between generations in most species is two years. Observations were 

 made on the influence of varying conditions of temperature, moisture, and food 

 upon the development of tiger beetles. 



The gum-lac insect of Madagascar, and other coccids affecting the citrus 

 and tobacco in that island, R. Newstead (Liverpool Univ., Inst. Com. Research 

 Trap. Quart. Jotir., 3 (1908), No. 6, pp. 3-lJ,, figs. 22). — A detailed description is 

 given of Gascardia madagascariensis, Lecanium nicotiano', and Alcurodcs voclt~- 

 Jioivi, the latter two being described as new sjiecies, and also of a number of 

 other scale insects observed in Egypt. 



On a new genus of Ixodoidea together with a description of eleven new 

 species of ticks, G. H. F. Nuttall and C. Warburton (Proc. Cambridge Phil. 

 Soc., l-'f (1907), No. //, pp. 392-4 1 6, fiffS- 45). — Definitions are given of the ana- 

 tomical terms used in the descriptions of ticks. The new species described by 

 the author belonged to the genera Ixodes, Hremaphysalis, Rhipicephalus, Am- 

 blyomma, Hyalomma, and Rhipicentor, tbe last genus being described as new\ 



An agricultural pest in Porto Rico, Bouvjer (Bui. Soc. Nat. Agr. France, 

 67 (1907). No. 9, pp. S20-825). — An account is given of the habits and life his- 

 tory of Seapteriscus didactylus, known in Porto Rico as cbanga," with instances 

 of the injury caused by this insect to various crops. 



Phalacrus corruscus as an enemy of cereal smuts, K. Friederichs (Arh. K. 

 Biol. Aiist. Land u. Forstw., 6 (1908), No. 1, pp.. 38-52, pi. 1). — Phalacrus cor- 

 ruscus has been found to exert an important influence in destroying the smuts 

 of cereals. The larvae of this insect have been found generally distributed in 

 infected ears of grain in cases of wheat smut, loose smut of oats, and barley 

 smut. A single infected kernel of grain may contain from 1 to 3 larvae. The 

 eggs are laid on the stem near tbe head of the grain or in tbe head near in- 

 fested kernels. The larvae feed upon the smut spores during their whole 

 development and as soon as the mature size is reached they leave the plants 

 and bury in the ground. An examination of fields infected with smut showed 

 that nearly every infected head of grain contained several larvae, sometimes 

 more than a dozen. The insect in question is, therefore, considered as being 

 of great importance in the control of snuits. Tbe author found tbat tbe 

 spores are all rendered incapable of germination by passing through the body 

 of the larvae,
