﻿New Species of Ipichic frcnx M<iinc 121 



fine and short hairs; epistomal margin sinuate, with a border of 

 stiif hairs longer at the center (abraded in old specimens) ; eyes 

 broad oval, broadly, rather deeply emarginate : antenna of bnt 

 little lighter color than the remainder of the body; club consider- 

 ably longer than funicle, more than one-fourth longer than wide, 

 with, the first suture nearly straight, the second curved and the 

 third strongly curved. 



Fronotum 1.26 times as long as wide; sides subparallel for nearly 

 two-thirds of the posterior part, then very slightly constricted and 

 broadly rounded in front ; front margin feebly serrate ; anterior 

 area moderately asperate ; summit prominent, with broad, deep, 

 transverse depression posteriorly; median impunctate area of pos- 

 terior half slightly elevated, disc and sides moderately but deeply 

 punctured, with a few short fine hairs ; posterior marginal line 

 distinct, slightly bisinuate. 



Elytra wider than pronotum. 1.86 times as long as wide; widest 

 before the middle, sides subparallel. weakly arcuate, broadly 

 rounded behind ; striae not impressed except the first, strial punc- 

 tures of moderate size, but deep and not arranged in regular rows, 

 those of the interspaces numerous, and similar; disc shining, nearly 

 glabrous; pubescence at sides not so sparse. Decliviti/ narrowly, 

 deeply sulcate, suture elevated, narrowed midway in the declivity 

 but wider toward the summit and apex ; lateral prominences high, 

 each with a sparse rovr of minute tooth-like granules ; hairs short 

 and sparse. 



31n]e slightly smaller but of the same general proportions ; front 

 similarly plano-convex, with a small, sub-circular area at the center 

 clothed with short hairs and divided by an indistinct carina ending 

 in an epistomal tooth which is coarser than in the female; with 

 the outer area of the front coarsely and roughly punctured; 

 lateral elevations of the declivity not quite so high, with the 

 granules smaller and more sparse. 



Type — K female. Orono. Maine, Aug. 20, 1919, I\r. W. Black- 

 man, collector; Lot No. M-155. 



Host Trees- — Balsam fir (Abies halsainea (Linn.) ^Miller), white 

 pine (Pinus strohus L.) and white s]>ruce (Picea canadensis 

 (Mill.) B., S. & P). 



Described from a small series of eight s]iecimens obtained by the 

 writer July 12, August 5 and 20, 1919. The beetles Avere found 

 in their burrows in dying and recently dead tAvigs, the entrance 

 opening always occurring at the base of a small branch. The 

 nuptial chamber is large and the burrow as a whole often 

 approaches the cave type characteristic of such species as CrypJw- 

 his baJso7nei(s but some of the burrows also show short egg-galleries. 

 The eggs are placed in niches either in the walls of the egg- 

 galleries or in those of the nuptial chamber. 



In balsam twigs P. patchi was associated with P. canadensis Sw., 

 P. balsameus n. sp. and Cryphalus balsameus Hopk. ; in white 

 spruce with P. canadensis ; while no associates Avere found in the 

 same twigs from white pine.
