apples in storage. As a single individual does not always con- 

 fine its attention to one apple, a few beetles may sometimes 

 injure a large number by biting into them. Harris records a 

 similar habit regarding peaches. The head and thorax of this 

 beetle are dark reddish brown, or almost black, thickly covered 

 with short yellowish hairs, the wing cases are light yellowish 

 brown mottled with irregular black dots. The under side of 

 the insect is very hairy. As this insect is quite conspicuous it 

 may be controled by hand picking. (Lot 826.) 



Conotrachelus nenuphar (Plum curcuHo).* 



At Lisbon, Maine, this insect has nearly ruined a crop of 

 plums, while the apples from orchards in many parts of the 

 State are reported as being commonly and generally infested 

 with this pest. (Lots 747, 757.) 



Blateridae (Wire worms).* 



A farmer from Lagrange says: ". . . these threaten to 

 ruin my potatoes. Every one raising potatoes in this vicinity 

 has the same complaint. We did not see anything of them on 

 this farm last year but one of my neighbors had them in his 

 potatoes. . . .'' Deep plowing and harrowing in the fall to 

 expose the pupa and beetle, as a preventive measure, are most 

 highly recommended. (Lot 763.) 



Scolytid Beetles in Pine Cones. 



Some specimens of cones from the White Pine, brought to 

 us by Doctor Chrysler of the University of Maine, collected 

 June 15 in Orono, were found to be mined by a Scolytid beetle. 

 Every cone on the branch brought in was affected. On open- 

 ing a cone, the whole structure was found to be mined through,, 

 two or three beetles being inside; and a gummy brown mass 

 at or near the base giving evidence of the work within. The 

 beetles made an exit at or near the apex. The cones were those 

 which started to grow last year. Professor J. M. Swaine, of 

 Macdonald College, Canada, who has made a special study of 

 this family of beetles, to whom specimens were sent, determined 

 them as Pityophthoriis coniperda. (Lot 734.)
