tion. The Wheat Midge, Dvplosis tritici, appeared in limited numbers 

 and was investigated in accordance with your instructions. A bulletin 

 was issued by me from the station dealing with chronological data in 

 regard to the pest, and a report submitted to yourself relating to this 

 and some other closely allied species. 



Many inquiries in regard to the Hessian Fly have been received, and 

 in order to meet a popular wish my report of 1890 to yourself, and ap- 

 pertaining to this species, has been received and adapted to a station 

 bulletin, which was issued in November of the present year. This, I 

 think, will afford the desired information to the farmers of the State 

 and reply to a vast amount of inquiry, which would otherwise have to 

 be answered by letter. 



The indications are that several important pests will demand atten- 

 tion next year, and, with your approval, considerable time will be spent 

 in becoming acquainted with the State and the people, with a view of 

 securing assistance from the farmers and affording the same in return. 

 The facilities offered by the station will enable me to push some inves- 

 tigations which I have not been able to do before. 



REPORT ON SEVERAL SPECIES OF CRANE-FLIES INFESTING MEADOWS 

 AND PASTURES, AND WHICH MAY ALSO PROVE INJURIOUS TO 

 WHEAT. 



Any extended study of the species belonging to this group of insects, 

 the Tipulidre, is impeded by many obstacles, owing, first, to the great 

 difficulty of securing a proper determination of the species involved, 

 and, second, to the fact that they are among farmers to a considerable 

 extent associated with cutworms, the larvae being known as cutworms 

 and the adults as "cutworm iiies; " so that it is not only a difficult task 

 to indicate the exact insect, but equally so to secure accurate data with 

 respect to its habits in the fields. In England these insects have long 

 ravaged fields of young wheat sown after clover, but in this country 

 such attacks have not often been observed. With the increasing pop- 

 ularity of clover- growing, both for pasture, meadow, seed, and fertilizer, 

 it would appear that we are on the verge of a new era with respect to 

 the effects of these insects in our clover fields; and even now one who 

 watches them carefully and notes the numbers of adults which are often 

 to be observed about our clover fields can not help but suspect that 

 they are working an injury which we either fail to observe, or, observ- 

 ing, attribute the loss occasioned thereby to other causes. So far as 

 grain crops are concerned, the indications are that the American hus- 

 bandman will have little trouble in preventing serious ravages in his 

 fields. What the future of our clover lands is to be, especially if allowed 

 to remain intact for a number of years, is yet to be seen. Of the species 

 studied, there is not one the ravages of which can not be almost en- 

 tirely prevented in young wheat by plowing the ground during late 

 August or early September, and there is every reason to believe that if
