A NEW ENEMY OF TIMOTHY. 
BY F. M. WEBSTER. 
In 1898 there was sent to the Department of Agriculture 
from Jamestown, Pa., a number of stems of timothy containing 
larvae. Nothing but Eurytoma, however, emerged from them, 
and as this is a genus of parasites, nothing could be determined 
relative to the true depredator. 
In July, 1904, a considerable number of timothy stems were 
sent to the Department from Marcellus, N. Y., some of which 
contained larvae unmistakably of Isosoma. 
In August and September following the receipt of this New 
York material, I found apparently the same insect infesting 
timothy at Dublin, and Falls Church, Va., in Maryland, about 
Washington, in Ohio, Michigan, Indiana, Illinois and North 
Dakota. Later, one of my assistants, Mr. Phillips, found seem- 
ingly the same thing in timothy at Knoxville, Tenn., Rives, 
Ky., and Cranesville, W. Va., while another assistant, Mr. 
Reeves, found similar larvae in timothy in Iowa and Nebraska, 
so that by December last we had material from 22 localities, 
in 13 States. With two or three exceptions we have reared 
adults from all of these collections, besides, in several instances, 
rearing them also from hay taken from barns during the past 
autumn and winter.
