SEPOBT OF THE ENTOMOLOGIST. Bid 



This field was located at least a half mile from any otlior whoreoTi 

 wlieat or rye had been raised during the season, and from it 1 again ob- 

 tained adult midges on the 10th, and again on the 14th of October. On 

 the IGlh of the same month the adults were also very abundant abowt 

 volunteer wheat in the fields. On going out just before sunset, and lyin;,' 

 down among the plants, I could see them flying about in great num- 

 bers between and just above the plants. They were again observed i;i 

 this locality on the 24th, after there had been several nights of sulVi 

 ciently low temperature to freeze water to the depth of half an inch. 



My last observation for the year was under date of 3d of Novenibct , 

 on which date an adult appeared in a breeding cage containing vohm 

 teer wheat. This cage had been kept continually out of doors, uud wmh 

 the same from which adults were obtained on the 23d and 30th of Octo- 

 ber. 



The first adult observed the present season appeared about my ]:\.\u\> 

 on the evening of the 20th of May, from which date they wct*^ obserx'cd, 

 under the same circumstances, in increasing numbers, until by the 1st 

 of June they were very abundant. 



But a single individual was observed in the fields during tliis tirae, 

 perhaps because only an occasional head was to bo seen in the early- 

 sown wheat, and it was not until the 10th of Juno that pollen was notc<l 

 on the wheat heads. 



On the 13th of June, in the field near Oxford, Ind., where I had ob- 

 served the insects so late the previous autumn, I found nearly full-grown 

 larvse on the heads of wheat and also swept adults from the grain. 



Failmg to find either larvro or adults in the fields about La Eayette, 

 Ind., I again visited the Oxford field on the 19th of June, and found 

 both larvre and adults rather more numerous than on the 13th. 



On the 20tl^ I found the larvoi on heads of wheat of a beardless va- 

 riety, in a field on the university experiment farm, and the same day 

 found on my lawn, in town, a head of blue-grass, not yet put forth from 

 the sheath, infested by quite a number of larva?. 



The larvte did not appear in any considerable numbers during the 

 season, and I could not observe or learn of their doing any perceptible 

 injury. 



Adults, however, continued to flock to my lamp during warm even- 

 ings up to the middle of August, and a very few until September, but 

 they did not occur in the fields or about volunteer wheat as they did 

 last season. 



THIRD REPOET ON THE CAUSES OF DESTRUCTION OE THE 

 EVERGREEN AND OTHER FOREST TREES IN NORTHERN NEW 

 ENGLAND. 



By Dr. A. S. Packard, Sjyecial Agent. 



In continuation of the work of the preceding year, I have to report 

 tliat there were observed or brought to my notice, in the season of 1885, 

 no cases of wide-spread or local destruction of evergreen or hard-wood 

 trees. ]^o extensive journeys were made into the Northern forests ; the 

 summer was spent on the shores of Casco Bay, Maine, and the time 

 given to observing forest insects and rearing species of Lepidoptera 

 and saw-fly larvas. A considerable number are at the time of writing 

 in the chrysalis state, and I hope to be more successful than formerly,
