The migration and dispersal of insects, J. W. Tutt {London: Elliot Stock, 1902, 

 pp. 132). — The author presents in a systematic manner the facts which liave been 

 recorded in entomological writings regarding the causes and conditions of the migra- 

 tion of various species of insects. 



Recent practical entomological literature, A. Tullgren {Ent. Tidskr., 24 

 {1903), No. 4, pp. 233-245). — The author briefly summarizes the results announced 

 in recent literature concerning methods of spraying and insects injurious to fruits, 

 garden vegetables, field crops, and ornamental trees. 



Statistical data concerning the causes of -white-head condition in grasses 

 in Finland, E. Eeiter {Ent. Tid>>kr., 24 {WO.i), No. 2-3, pp. 7io'-i,^.5).— The disease 

 known as white hea<l in grasses was carefully studied in various parts of Finland, for 

 the purpose of arriving at a conclusion regarding the insects which were most con- 

 cerned in producing this condition. The statistics which are reported by the author 

 were collected during the years 1889 to 1901 and indicate that the pests chiefly con- 

 cerned in bringing about white head are the following: Pediculoides graminum, Tar- 

 so?(('//a(.s- culmicolus, Aptinofhrijw nifa, Eriophycx cornutus, etc. 



Descriptions of some new species and varieties of Canadian butterflies, J.

 pi. 1, figx. 2). — Descriptive and economic notes are given on a number of butterflies

 cc7hs, and Pamphila ntanitohoides. 



Diffusion of the hawk moths in North America, F. M. Webster {Canad. Ent.,

 American species belonging to this family appear to have migrated northward from

Precocious development of the pupal and adult organs in the larvae of 

 liepidoptera and Coleoptera, H. J, Kolbe {Allg. Ztschr. Ent., S {1903), Xo.s. 1, pp. 

 1-9; 2-3, j)j). 25-30, tigs. 12). — The precocious development of various insect organs 

 were studied with special reference to the histology of these structures. Particular 

 attention is given to a study of these questions in the case of Dendrolimus pini, which 

 is injurious to pine trees. 



A revision of the Nearctic Chrysopidae, N. Banks {Trans. Amer. Ent. Soc, 29 

 {1903), No. 2, pp. 137-162, pi. 1).—A brief account is given of the habits, life history, 

 and economic importance of these insects. The greater part of the article is occupied 

 with a detailed account of the various species of this family which occur in North 

 America. Several of these species are described as new. A bibliography of the sub- 

 ject is appended to the article.
