hypnm (ibbreriatiis, carefal and extended descriptions of the larvie being 

 given in each case. The experience witli Drasterius would indicate, 

 in connection with our own experience, which is quoted, that the larva 

 combines the carnivorous and phytophagous habit, as in so many other 

 insects. 



In Bulletin No. 85, of the New Jersey Experiment Station, Prof. J. B. 

 Smith gives his experience with kainit against wireworms whicli he 

 found on a large scale to be strikingly successful. Prof. Comstock's 

 experiment was conducted in the laboratory and on a small scale. 



Insects Injurious to the Blackberry.* — Prof. John B. Smith has published 

 a little bulletin under this title, in which he indicates the importance 

 of the small fruit industry in portions of New Jersey and considers the 

 following enemies of the Blackberry : The Red-necked Cane-borer {Agri- 

 h(s rufiGollls), the Blackberry Crown-borer [Bemhecia marginata), the 

 Giant Koot-borer {Prionus laticoUis), and the Blackberry Midge {Lasi- 

 optera farinosa). The life-histories of these insects are presented in a 

 lucid and popular manner and the author's original results are indicated, 

 as comi^ared with those from other vsources which are duly credited. We 

 notice that the acting director of the New Jersey Experiment Station 

 has the habit of signing his name at the end of tlie bulletins, which 

 gives the erroneous impression to one not examining the ])aper carefully 

 that he is the author. Some other arrangement, like a formal letter of 

 submittal, could be made to advantage. 



Farm Practice and Fertilizers to control Insect Injury.t — Under this title 

 Prof. Smith lias brought together a number of very useful sugges- 

 tions to farmers and which involve the application of ijreventive or 

 remedial measures as a part of the regular farm routine. He discusses 

 in the main the value of fall plowing, the use of different commercial 

 fertilizers, rotation of crops, clean culture, and the effect of different 

 seasons of planting and of harvest. The bulletin is principally sugges- 

 tive and many of the suggestions are founded upon experiments and 

 upon the ])ublished exj)erience of other entomologists. It is written in 

 a clear and practical manner and is calculated to make a favorable im- 

 pression upon the intelligent farmer. Prof. Smith places entire cre- 

 dence in the poi)ular idea of farmers that where kainit is freely applied 

 as a fertilizer to the roots of orchard trees it will apx)ear upon the surface 

 of the leaves. He even goes so far as to state that where this sub- 

 stance has been thus applied he has seen every leaf covered by a per-
