Report of Observations of Injurious Insects and Common Farm 

 Pests during the year 1886, 2vlth Method of Prevention 

 and Remedy. Tenth Report. By Eleanor A. Ormerod. 

 London: Simpkin, Marshall & Co. 1887. 



Miss Ormerod's annual reports on injurious insects continue 

 to increase both in size and interest. This tenth report, for the 

 year 188(3, runs to 112 royal 8vo pages, together with six pages 

 of preface ; and, as usual, is fully illustrated. Naturally the chief 

 interest is centred in the full notice of the Hessian Fly {Cecidomyia 

 destructor) and its attack in this country, recorded from such 

 distant localities as Essex, Herts and Beds, Inverness and 

 Perthshire. This occupies nearly seventeen pages, and is full of 

 interesting and important detail, as might be expected from the 

 painstaking author. 



Other special reports are made on the "Tulip-root" disease 

 of oats, probably due to a species of Anguillulidse (nematode 

 worms), similar to that causing cockle in wheat ; and we can only 

 hope that, now such detailed notice has been called to this pest, 

 it may enable our agriculturists, especially in Scotland, where 

 the disease seems prevalent, to assist Miss Ormerod in arriving 

 at a fair knowledge of this apparently destructive pest during 

 the present year. The Mustard Beetle [Phisdon hetidce), whose 

 attacks during the last two' years have almost entirely stopped 

 the cultivation of white mustard in my own district of Essex ; 

 Warbles (Qistridse) ; and many other better-known insect enemies 

 are fully reported upon ; and the information gained and so faith- 

 fully recorded should prove of value to all practical men, as well 

 as of interest to all entomologists ; and their gratitude must be 

 expressed to Miss Ormerod's continued and self-denying efforts 

 in supplying a want which has been so long felt in this country.
