An apparatus for collecting small arthropods quickly and in large num- 

 bers, A. Berlese {Redia, 2 {1904), No. l,pp. 85-89, figs. 2).— The apparatus described 

 in this article depends for its effectiveness upon the application of heat to the material 

 in which small arthropods are concealed. 



Moldy soil or other rubbish is placed in a receptacle in the top of the apparatus, 

 the material lying upon a metallic screen with small apertures. Beneath the metal- 

 lic screen which holds the material to be investigated is a funnel leading to a small 

 tube containing alcohol or other preserving fluid. The funnel is surrounded by 

 water which may be heated to a suitable temperature. The heat gradually dries 

 out the soil or other material in which the insects are hidden, causing them to crawl 

 downward in search of moisture and in so doing they fall into the metallic screen 

 and ultimately into the funnel.

 Hassali. ( U. S. Dept. Agr., Bur. Anim. Indus. Bui. 39, pte. 12, pp. 8.19-902; 13, pp. 

 :><). ;-950). — In these two parts of the index-catalogue the authors present an alpha- 

 betical list of authors for the letter K. 



Insects injurious to grain and fodder crops, root crops, and vegetables, 

 J. Fletcher {Canada Cent. Expt. Farm Bui. 52, pp. 48, pis. 8). — The author presents, 

 for the use of farmers and gardeners, a general account of the common insect pests 

 which attack cereals, forage plants, fruit crops, and garden vegetables. 



The most effective insecticides are described and formulas suggested for preparing 

 them. Among the insects injurious to grain and fodder crops mention may be made 

 of Hessian fly, jointworm, wheat-stem maggot, wheat midge, western wheat-stem 

 sawfly, grain aphis, wireworm, white grub, corn worm, grasshopper, pea moth, pea 

 weevil, bean weevil, destructive pea aphis, clover-seed caterpillar, clover- seed mite, 

 army worm, etc. The common pests of root crops and garden vegetables are also 

 described and notes are given on means of combating them. 



Insects of Hermand Jethou, W. A. Luff | Guernsey Soc. Nat. Sci. Rpt. and Trans. 

 1904, pp 374-390). — The insects observed in these islands are listed and notes are 

 given on the habits of some of the more important species. 



The insect galls of Indiana, M. T. Cook {Separate Jem n Ind. Dept. GeoJ. andNat. 

 Resources Ann. Rpt.. 29 I 1904), pp. 801-871, figs. 52) . — This contribution to the knowl- 

 edge of insect galls is to be considered a part of the author's proposed monograph of 

 the insect galls of North America. The present contribution includes a discussion of 

 trails observed on plants in Indiana, 



The cotton-boll weevil, P. Marciial {Jour. Agr. Trop.,5 {1905), No. 50,j>p. 229- 

 B34 >• — A historical account is presented of the origin and distribution of this pest and 

 the early literature relating to it. The habits and life history of the insect are dis- 

 cussed with particular reference to the conditions which are favorable to its distribu- 

 tion. Brief notes are also given on some of the conditions which are unfavorable to 

 the pest, and upon its natural enemies. 



The cotton caterpillar {Jour. Jamaica Agr. Soc, 9 {1905), Xo. 9, pp. 312-317). — 

 Apparently the caterpillar, which has recently done most damage to cotton in 

 Jamaica, is the common cotton caterpillar of this country. The insect is described 

 in its various stages and notes are given on its habits and life history. 



As a result of a number of spraying experiments with Paris green and arsenate of 

 lead it is recommended that arsenical poisons be thoroughly applied to cotton plants 

 as soon as the caterpillars appear. In moderately dry weather this application can 

 best be made in the form of a dry mixture with lime or some similar substance. In 

 wet weather arsenate of lead dissolved in water is recommended. 



Methods of combating the cotton-boll weevil and the cotton caterpillar, 

 A. L. Herrera {Com. Par. Agr. [Mexico 1 ], Circ. 24, pp. 2).— Brief notes on the 

 approved remedies for the control of these two insects.
