160 THE CANADIAN ENTOMOLOGIST. 



black pepper should be given and the cavity refilled with cheese and 

 covered carefully with calico. 



Leather Jackets. — The larvse of the Crane Flies or Daddy Long-legs 

 as enemies of grain crops and grass are treated of, and the use of nitrate 

 of soda as a quick-acting fertilizer is recommended. 



The Hessian Fly occurred at one locality, and a full resume' of the 

 subject, compiled chiefly from United States reports, presents the 

 important characteristics of the attack and the best remedies, in an 

 attractive manner. Stress is laid on the importance of destroying the 

 " flaxseeds " both in screenings and in stubble. 



The Currant Gall Mite, an enemy of the black currant, which yearly 

 causes nivich loss, is still under observation, and some interesting new 

 experiments are reported as to discovering the method of distribution of 

 the mites. It was found that plants cut down to the ground could be 

 moved from an infested plantation, and there was no conveyance of 

 infestation in the earth at the roots. 



Flour and Grain Beetles. — Under this heading several familiar 

 insect enemies of stored grain are treated of, viz.: The Rust-red Flour 

 Beetle, the Cadelle and the Mediterranean Flour Moth. 



The Grouse Fly (a parasite on grouse), the Hop Flea-beetle and the 

 Land Planarian are the subjects of articles of much scientific interest. 



Short Notices. — A new feature of this second series of Dr. Ormerod's 

 Reports is a collection of short notes, in which recently-discovered facts 

 on the appearance, habits, treatment or remedial measures are given of 

 insects previously referred to at length in former Reports. Here we 

 find, among other things, a mention of the occurrence in Fngland of our 

 troublesome Canadian enemy of the apple, the Eye-spotted Bud-moth ; 

 also a recommendation of a caustic alkaline spraying mixture of crude 

 potash and caustic soda ; and an attack upon strawberries by three 

 species of ground beetles, the worst culprit being the Red-horned Ground 

 Beetle (IIa7-palus rieficornis). 



This valuable Report of 152 pages is replete with useful and practical 

 knowledge, which must of necessity be of enormous value to all who read 

 it. The illustrations are excellent and the volume contains a most 

 complete index, which much facilitates reference, J. F.
