REPORTS OF OBSERVATIONS AND EXPERIMENT 4!J 



(7) That in view of these results, the scraping off of the BggB or their 



removal or destruction by means of* washes will be very effective, even 

 if not used oftener than once in two weeks during the period of egg 

 deposition, and probably that a single thorough removal of the i 

 after the period of egg deposition has past will prevent f 

 majority of bots in gaining access to the stomach, or at least so large a 

 proportion, that little injury is likely to occur. 



The Horn Fly. — This is the first season in which Hcematobia serrate 

 has proved troublesome in this vicinity. Eeports late last year indi- 

 cated some trouble in the eastern portion of the State, and in Ka 

 it was reported much farther west, but was not observed in this particu- 

 lar locality. I have been informed, however, by some stockmen that 

 it was seen late in autumn. The present season it appeared in large 

 numbers in the first part of July, numbers being sufficient to seriously 

 annoy stock, and from that time on the pest has been very plentiful 

 and troublesome. 



The Clover-hay Worm. — This species was one of the conspicuous p< 

 of the season, specimens being received from different parts of the 

 State and reports from other localities sufficiently to show that the 

 clover hay quite generally throughout the State and in adjacent locali- 

 ties has suffered largely from its attack. The injury has been of the 

 characteristic form, the lower portions of the haymows and stacks 

 being eaten, filled with webs and excrementitious matter, entailing a 

 considerable loss. Aside from Fyralis costalis. the Fyralis farinalis has 

 beeu quite abundant, appearing in large numbers in some of the barns, 

 and it is pretty certain that a considerable portion of the injury may 

 be referred to that species. Judging from the abundance of the moths 

 in certain cases, it would seem to be the more abundant form, but in a 

 number of cases where specimens have been received the larvae were 

 of the costalis form and proved upon breeding to be that species. 

 There is probably no difference in the habits of the two forms, so far as 

 their clover-feeding habit goes, that would necessitate any difference 

 of treatment. I have, in a few cases, recommended the use of bisul- 

 phide of carbon for this pest with special precaution as to its use on 

 account of inflammability of the liquid, and while I have not had the 

 opportunity to test it personally, nor receive reports from any « ho may 

 have tried it at my suggestion, I am confident that it could be used for 

 the destruction of the larva*, and that by this process barns could be 

 freed from the pests without the necessity of the cleaning out ot' the 

 old hay and burning the webbed portions, a process which involves 

 considerable labor and is sometimes quite inconvenient to adopt. 



Clover-seed Caterpillar. — This species, Qrapholiiha interstinetinta.hA* 



received attention during the last two or three years, but its increased 



abundance the present season makes it worthy of still further mention. 



It has been forwarded from different localities and has certainly
