hypnus abbreviatus, careful and extended descriptions of the larvee being 
given in each case. The experience with 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 which he 
found on a large scale to be strikingly successful. Prof. Comstock’s 
experiment was conducted in the laboratory and on a small seale. 
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- 
lus ruficollis), the Blackberry Crown-borer (Bembecia marginata), the 
Giant Root-borer (Prionus laticollis), and the Blackberry Midge (Zasi- 
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 compared with those from other sources 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 the bulletins, which 
gives the erroneous impression to one not examining the paper 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.;—Under this title 
Prof. Smith has brought together a number of very useful sugges- 
tions to farmers and which involve the application of preventive 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 published experience 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 popular idea of farmers that where kainit is freely applied 
as a fertilizer to the roots of orchard trees it will appear 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-
