three bushels. Others estimated their loss at from three to fifteen 

 bushels per acre. I examined corn fields in the vicinity of Black- 

 berry (Kane county) that had been damaged by locusts. The insects 

 would gnaw oft' the end of the ear (cob, kernel, and husk with silk) 

 with as great a degree of nicety as could be attained with a sharp 

 knife. The kernels would then be eaten for quite a distance towards 

 the butt of the ear, beneath the husks. The damage was estimated 

 by farmers at about fifteen bushels per acre — rather high, I think. 



"In Livingston county the locusts appeared in injurious numbers 

 in a strip averaging five miles in width. On either side of the bor- 

 ders the locusts were not heard from." 



The CHINCH BUG was extremely rare in his vicinity, not coming to 

 his notice until August 3, when a number were found in the larval 

 stage. 



The GRAPE BERRY MOTH {Euclemis botrana, SchifiP.) has been very 

 destructive to grapes in Livingston county for the past two years. 



A dipterous larva was noticed injuring celery, both last year and 

 the preceding, in both Livingston and Kane counties. It begins to 

 gnaw the base of the stalk, gradually progressing upwards. Its 

 presence is easily traced by worm-eaten passages, which early turn 

 to a rusty color. The maggot is about three fourths of an inch 

 long, footless, dirty pale yellow, posterior extremity truncate, the 

 head with the usual two black hooks of dipterous larvae. It pupates 

 within the celery stalk, emerging as an imago early in June. "The 

 single fly I obtained may be described as follows : The general color 

 is black, sprinkled with yellow hairsj, the head being dark brown. 

 The wings are clear, with veins light yellow, as also are the legs. 

 The body is about 7 mm." 



The following notes on the prevalence of the cabbage worm will 

 be of interest as related to the effect oi flacherie: 



"While in Kane county, 1 found the cabbage plants io be almost 

 totally destroyed so far as heading was concerned. Pieris rapce was 

 everywhere numerous. The heading process having been prevented, 

 the plants grew rapidly upwards to a considerable hight, putting out 

 long, slender ' leaves, and presenting a very peculiar appearance. 

 These leaves were infested by the cabbage aphis. The crop in Black- 

 berry and Kaneville townships was a failure. This was in striking 

 contrast with the cabbage patches of Reading township (my own 

 home). Here, in the previous years, the Pieris rapes had almost en- 

 tirely prevented the rearing of a sound cabbage head, while during 

 the past year I failed to obtain a single specimen of the larva, 

 though occasionally an imago would be seen flitting by. Their ab- 

 sence was due chiefly, I think, to the parasitic disease which de- 

 stroyed so many two years ago. Around Streator, where large fields 

 of cabbage may be seen every year, the pest was far less trouble- 

 some than in former years. While on the subject of P. rapes, I will 

 remark that I repeated the experiment, several times this summer, 

 of preventing oviposition of the female by applying kerosene emul- 

 sion freely on the plants during the time the butterflies were about." 



The raspberry measuring worm, Eiitrapela transversata, Drury, 

 was sufficiently numerous near Ancona, during the summer of 1884,
