The Insects of the Clover Plant. By J. A. Lintner; 8vo., 17 pp., with 6 cuts. 



This excellent paper forms part of the Fortieth Annual Report of the New York 

 State Agricultural Society, and contains detailed descriptions of the insects most destructive 

 to clover, with references to all the species known to feed on this j)lant. 



Ottawa Field Naturalists' Club. 



The second volume of the Transactions of this active body of naturalists is at hand. 

 It is a neat pamphlet of 44 pages octavo, with one excellent plate illustrating a new 

 species of Porsocrimcs from the Trenton limestone, accompanied by a description, with 

 some remarks on the genus by Dr. James Grant. In addition to the Annual Report of 

 the Club, the volume contains the inaugural address of the talented president, James 

 Fletcher, Esq. ; a paper on Some Coleoptera Injurious to our Pines, by W. H, Harrington ; 

 one by Prof. J. Macoun on the Capabilities of the Prairie Lands of the Great North-West, 

 ^s shown by their Fauna and Flora ; and other interesting contributions. We congratulate 

 our Ottawa friends on the good work they have done this year, and sincerely hope that 

 their active efforts may have the effect of promoting a general love for natural history 

 .among the residents of the capital of our Dominion. 



INSECTS INJURIOUS TO CLOVER. 

 By Wm. Saunders, London, Ont. 



1. The Cloyer Seed Midge — Cecidomyia leg uminicola. 



2. The Clover Root Borer — Hylastes trifolii. 



3. The Clover Stem Borer — Languria Mozardi. 



4. The Clover Leaf Midge — Cecidomyia trifolii. 



5. The Clover Hay Worm — Asopia costalis. 



6. The Clover Drasteria — Drasteria erechtea. 



7. The Clouded Sulphur Butterfly. — Colias philodice. 



There are many insects which injuriously affect this important crop, but it is only 

 within the past three or four years that special attention has been paid to them. Within 

 this period they have been closely studied, both in the field and in confinement, by 

 men in every way qualified for the work ; by the Entomologists of the Department of 

 Agriculture in Washington, Professors Riley and Comstock ; by the State Entomologist 

 •of New York, Prof. J. A. Lintner of Albany, and others. From the several valuable 

 reports issued by these Government and State officials, much of what follows has been 

 gleaned ; and the object aimed at here is to present the information obtainable in a 

 popular manner, to incorporate with it such additional facts in reference to the occurrence 

 of these insects in Ontario as our limited opportunities for observation have enabled us 

 to acquire, and to present all in as convenient a form for reference as possible, so as to 

 make this part of our report of special value to our agricultural readers. 



In a late paper on Clover Insects, published by Mr. Lintner, he enumerates no less 

 than forty-six injurious species, about half of which are known to occur in Canada. The 

 injury done by some of these is insignificant, either on account of the insects feeding on 

 many other plants besides clover, or else for the reason that these species seldom occur in 

 -any remarkable abundance; while, on the other hand, there are included in this list several 

 insects which have already become, or promise to become, formidable foes to this crop ; 

 and amongst the latter, none are attracting so much attention as the Clover Seed Midge, 

 an insect which has fairly established itself in our country, and is likely to prove a serious 

 •drawback to the growth of clover seed in our Province. This species will first claim our 

 attention.
