AGRICULTURAL EXPERIMENT STATION. 117 



Mr. C. A. AVood of Searsport sent us a species of Rove Beetle, 

 Ancyrophorus planus, and The Four-spotted Pithyopiiagus, P. 4- 

 guttatus. Both were accused of destroying the kernels of sweet 

 corn at the top of the ear. Ears of damaged corn accompanied the 

 accused. We were able to acquit the above beetles as the corn 

 showed the unmistakable work of the Corn Worm which was con- 

 sidered in our last report on P. 119. The irue culprits, full fed, 

 had probably crawled away to transform. The above insects were 

 in the corn to feed upon the sugary and starch} - matter that flowed 

 from the broken kernels. 



The White Grub 01 larva of the May Beetle, Lachnosterna fusca, 

 has been doing much damage to grass lands in the vicinity of Btidg- 

 ton. As there is no ceitain remedy known for this insect it would 

 be advisable to do some field work upon it and try the most hopeful 

 remedies suggested by entomologists and prove their value or worth- 

 lessness. 



The Pear Blight Beetle working in the limbs of apple trees and 

 boring the wood full of small channels is a new injurious insect to 

 the State. 



We reeceivd specimens from two widely separated localities so it 

 must be widespread. Its presence can be detected by small shot- 

 like holes in the bark. It attacks healthy trees and there is no 

 remedy but to cut the branches infested and burn them. 



The Bean Weevil spoken of in our last report is considered and 

 illustrated in this. The Horn Fly t was quite abundant in some 

 localities. It is migrating eastward an! wa? q lite abundant at 

 Hudson and other localities in the Penobscot valley this season. 



The Carrot Fly, Psila rosce, was received from Mr. C. H. Morrell, 

 Pittsfield. It was found infesting stored carrots. This is a Euro- 

 pean insect never before detected in the United States. The carrots 

 were literally alive with maggots. 



Beets in this region were badly infested by a species of Antlio- 

 myia or Beet Fly, the larvae of which eat the pulp from the leaves, 

 leaving the epidermis. The eaten spots are clear whitish and in 

 them the maggots can often be seen between the epidermi. 



The Currant Plant Louse, Aphis vibes, L. has been doing dam- 

 age to gooseberries in Aroostook and Piscataquis counties the past 

 season, destroying the foliage and causing a second growth of small 

 leaves.
