Report of the state entomologist 19 13 173 



The damage was so extensive in some places that fields of clover, 

 grown for seed, were found not worth cutting at that time. Prof. 

 William H. Brewer of Yale College stated that his father, Henry 

 Brewer of Enfield Center, Tompkins county, who was an enthu- 

 siastic grower of clover and clover seed, was familiar before 1848 

 with an insect which attacked clover and was presumably this 

 species. Some idea of the abundance of the pest may be gained 

 from the following. In 1888 Miss E. J. Phillips, writing to the 

 Department of Agriculture at Washington, stated that her brother 

 had cut enough clover in the morning to feed 12 cows at night, and 

 allowed it to lie in the wagon all day and when he removed it 

 therefrom at night the bottom of the wagon was literally pink 

 with larvae. Doctor Lintner has placed on record an instance where 

 the second crop of clover was cut and put on the scaffolding above 

 the barn floor. Four or five days later large numbers of the larvae 

 were observed upon the floor beneath, giving it an appearance of 

 having been sprinkled with red sand. Mr C. W. Stewart of Newark, 

 N. Y., communicating with this office in 1897, stated that the crop 

 of clover seed on 25 acres was completely ruined by this insect. 

 Doctor Fletcher has recorded serious injury in Ontario and Pro- 

 fessor Davis in Michigan. 



Distribution. This species is known to occur generally in New 

 York State. It has been recorded from Ohio, Michigan, Illinois, 

 the District of Columbia, Virginia, Ontario, Canada, and is probably 

 widely distributed over the eastern half of this country at least. 

 Miss Ormerod has also recorded the species from England. 



Name and identity. This species was first described by Doctor 

 Lintner in February 1879 as Cecidomyia trifolii, the 

 present name of leguminicola being proposed later, because 

 trifolii was preoccupied by an European species. More recently 

 this insect has been removed from the genus Cecidomyia and is now 

 known as Dasyneura leguminicola Lintn. 



This small, fragile, dark brown and reddish midge can not be 

 readily separated from the European clover leaf midge, Dasy- 

 neura trifolii Loew, which has become well established in 

 this country. Dasyneura leguminicola may be most 

 easily distinguished by the relatively large wings and the straight 

 third vein in connection with the very long, slender ovipositor, this 

 organ being distinctly longer than the body, while the lobes are 

 relatively short and stout and have a length only about three and 

 one-half times their breadth. The venter of the abdominal seg-
