causing them to shrivel, dry up and die. In two counties alone, 1,624 

 acres of mangolds were infested (Ormerod). This last summer some 

 Anthomyiffi larvae were discovered by me in Middleburgh, N. Y., exten- 

 sively mining the leaves of the garden beet (Beta vulgaris). Judging from 

 published descriptions and figures, I believed it to be identical with the 

 European species of the same habits, and that it had been a recent 

 importation thence. Examples of the eggs, larvae, puparia and flies were 

 sent by me to Mr. R. H. Meade, of Bradford, England, who has been 

 recently making special study of the Anthomians, and particularly of the 

 North American species, as may be seen in a paper in the March number 

 of the last volume (xiii) of the Canadian Entomologist, giving the 

 result of his study of the collections in this family, belonging to the 

 Museum of Comparative Zoology at Cambridge, Mass. Mr. Meade finds, 

 among the examples which I sent to him, reared by me from my larval 

 collections at Middleburgh, no less than three distinct species — all differ- 

 ing from A. betcE — two believed to be undescribed — and one identified as 

 Chortophila fioccosa Macq. Tt seems somewhat remarkable that all these 

 should have been obtained from larvse feeding at the same time, upon a 

 small garden bed of beets, containing about fifty square feet of surface. 

 The description and general history of the new species will probably be 

 given in my forthcoming Annual Report. 



NOTES ON ISOSOMA ELYMI, French. 



BY G. H. FRENCH, CARBONDALE, ILL. 



In my notes in the March number of the Can. Ent., the idea is con- 

 veyed that this species obtained from the wild Canada rye grass, may 

 prove to be identical with the wingless form obtained by Prof. Riley and 

 myself from wheat stalks, and which Prof. Riley has since named in the 

 American Naturalist, / Tritici. At the same time doubt was expressed 

 as to their identity, because at the time of writing there were still larvse in 

 the grass straws, while /. Tritici pupated in the fall, both in the breeding 

 jars and in the field. Since the article mentioned has appeared, I have
