WO except tlic losses oceasioiied l>y (lie more or less sponidic iittaekH of certain species of the 

 Scoiytitla- alieatly iiieiilioiied, pi()l)al)ly tliis oj)iiiloii is about correct. Five of tlicse si)ecies liave 

 been described, all pine feeders and beetles of tlio largest size, with elonj^ate cylindrical bodiiis 

 and extremely Ion},' antenna', those of the 7nalo being two oi' three times as long as the remainder 

 of the insect. The pine sawyeis are most tmuMcsonie in tlit^ mill yard, and their lar^e white larvie 

 often do mnch damage to logs by eating great holes throngh their solid interior. While harrowing 

 in the wood the larva' nuike a ])ecnliar grating sound that may be heard on ipiiet nights at a consid- 

 erable distance. This is a familiar soniid in the lumber camps of the North, and has probably

given rise to the name of pine sawyers, by which these insects aic known. Monohammus von- 

 /««or Kby. is a large gray species destructive in the binibering districts of the Northern United 

 States an<l Canada; M. Iltillfitor Fab., a mottled brov.ii beetle, rejilaces the above species in the 

 South, and ,1/. mticitlosiiK Ilald. occurs in the West; .1/. .scKtrlliitiis Hay. is widely distributed and 

 abundant from the Atlantic to the I'acilic, and .1/. nuirmordlor Kby. is a rather rare northern 

 form. 



Among other borers belongiag to the same family as the .sawyers, the majority of which infest 

 White Pine, may be mentioned Griocephaltis (igrr.sd.s Kby., <'. ohnolctux IJand., Aurmum mastuin

In the Coleopterous family Bu])restid:e are many borers which infest i>ine.

 Germ., C.floricola Gory, and ('. scahripennis Lap. and Gory. These beetles are 

 graceful in form, luird of texture, and many are brilliantly metallic^ Their larva' 

 are slender, white grubs with very large, round llat heads. Some of this family 

 attack living trees and do injury to the sapwood and to felled timber in the same manner as the 

 sawyers, but the majority of them ])refer devitalized material, and their attacks are usually 

 secondary to some more injurious sjiecics.

THE W^HITE-PINE ^VEEVIL. 



In the White Pine forests of the >'ortheru States, i)arti(ularly in those of a second giowth, 

 one'.H attention is often drawn to tlie great number of deformed trees. They sometinu'S occur 

 singly, but more often in grou]>s. The insect that is res])onsible for this damage is the Mhitepine 

 weevil (I'is.soihs xtrohi Pe(;k). This beetle is a mend)cr of the family ("nrculionid;e. and is about a 

 fourth of an inch in length, of oval form, red ;ind brown in <'oIoi-, with its elytra marki'd with white
