IXSKCTS AFFECTIXr, PARK AND WOODLAND TREKS 399 



Tile attacked shoot continues its growth clurinL; the early part of the season, 

 but soon the yriibs cause so much injury that it heL^M'ns to wilt and wither 

 about the niitldle of July, and the tender ])arts aliove dry and perish. 

 Examination of the affected shoot rt^veals small oval cells, about '{ inch 

 lont,^ placed lenj^thwise in the center of the stem. The)' are so very close in 

 some cases that their entls are nearly in contact, and in others the\- are 

 more or less widely separated by masses of borings, antl not infrecpienilv 

 small cells may be found in the sapwood just beneath the bark | pi. 19, 

 fig- 6]. 



Each of these contains a white phunp larva or .i,n-ub, which later chano-(_-s 

 to a pupa and the adult insects apjjear abroad next sj)rintr. Pu]jal cells 

 of this weevil ma\' also be found under the bark of ])iiie hx^-s and stumijs. 

 Mr L. II. Joutel has recently called the writer's attention to the breedin*-- 

 of this insect in tlie bark of a tret; 6 inches in tliameter, a fact pre- 

 viously mentioned. I)r bitch was (juile confident that eggs deposited 

 in the spring become; mature Ijeetles within a year. This weevil was 

 observed by the writer to be very common ami injurious to white |)ines at 

 Karner in 1901, and the following year he hail an o|)|)ortuniiy of stuchiu"- 

 recent work of the jjest in small white pines at Salem X. \'. These obser- 

 vations indicate that the attack frequently begins just below tht- terminal 

 whorl antl is evidenced by the small irregular masses of |)itch and the lighter 

 color of the foliage above the ])oint of injury. The larva or grul) makes a 

 longitutlinal burrow in the inner bark, which is closely followed bj- a drviu"- 

 and shrinking of the tissues immediately above ami adjaccMit to the wound, 

 forming a darker, sunken area on the shoot. The work is extended down- 

 ward under the bark to the next whorl ami jjossibly below. The infested 

 bark soon becomes a mass of burrows and deca\ing matter, eventuallv 

 peeling off and revealing oval pupal cells in the wood. Its work was also 

 observed here and there in other parts of the .State. The record of captures 

 by beating certain trees in 1901 may be of interest, as it shows the persist- 

 ence of this species in small numbers, at least, throughout a long period. 

 The record is as follows: June 4, 6; June 13, 18; June 19, 1 ; |une 26, 2;
