 Scolytida' already mentioned, probably this opinion is about correct. Five of these species liave 

 been described, all pine fccilcrs and beetles of tlio larijest size, with eloii^ato eyliiidiieal bodies 

 and extremely lonjj antenna', those of the male beiii^ two or three times as long as the remainder 

 of the insect. The pine sawyers are most troublesome in the mill yard, and their large white larvic

secondary to some more injurious species.

THE WHITE-PINE WEEVIL. 



In the ^Vhite Pine forests of the ISorthern States, particularly in those of a second growth, 

 one's attention is often drawn to the great number of defornied trees. They sometimes occur 

 singly, but more often in groiqis. The insect that is resjionsible for this damage is tln^ white pine 

 weevil (J'tusailrs xliohi Peck). This beetle is a member of the family CnrcuIionid;e, and is about a 

 fourth of an inch in length, of oval form, red and brown in coh^r, with its elytra marked with white
