During the last week in September of 1883, a package of insects in 

 roots of grass was sent to the New York State Agricultural Society, by 

 Mr. M. H. Smith, of Redwood, Jefferson county. New York, with the 

 following statement in regard to them : 



I herewith transmit specimens of (to us) a new and formidable grass- 

 destroying insect, together with portions of grass destroyed by them, 

 and also some of the soil, for the purpose of examination. If the 

 insect is known to you, and there is any known way to exterminate it, 

 please inform us at once. The evidence of its destructive work was 

 first discovered in June of 1882, by Mr. H. C. King, of Hammond, St. 

 Lawrence county. At haying time, about the middle of July, he no- 

 ticed about three acres of his timothy grass to be apparently, prema- 

 turely ripened. In the fall he observed that there was no aftergrowth, 

 and that the stubble was as dead as if it had been boiled. Search was 

 made among the dead roots without any discovery. The following 

 spring the field was entirely barren of timothy, but some clover seeds 

 and thistles occupied the ground where at least one and one-half tons 

 of timothy to the acre, under favorable circumstances, would have been 

 cut. In June of 1883, Mr. King discovered other fields to be affected 

 in the same manner, and instituted a search which has recently resulted
