not excessively long when compared with those of several other 

 species of this genus. In the material at hand they vary from 3| 

 cm. to 7 cm. with an average length of 4.2 cm. The egg niches, 

 where these are still recognizable, occur on both sides of the gallery 

 and are not closely arranged — usually being 2 mm. or more apart 

 so that the number of eggs laid by each female is probably not 

 great. 



Pityophthorus occidentalis sp. nov. 



Reddish brown to nearly black in color; 2.8 times as long as 

 broad. 



Male. Length 2.5 mm. Front convex with distinct rough 

 transverse carina below level of upper inner angle of eyes, 

 coarsely and roughly punctured above, slightly excavated and more 

 finely punctured below carina, with distinct median vertical carina 

 from transverse carina to margin of epistoma; fine short hairs over 

 entire front but becoming more conspicuous cephalad; edge of 

 epistoma emarginate and bisinuate, bordered with coarser and 

 longer hairs; eyes oval with rather wide and deep emargination ; 

 antennae light reddish -brown, club oval, with first three segments 

 sub-equal and fourth segment shorter; first and second sutures on 

 ventral face nearly straight, third strongly arcuate; outer part of 

 funicle one-half longer than pedicel. 



Pronotum slightly longer than broad (14:13), widest behind the 

 summit; sides of basal half slightly arcuate, faintly constricted in 

 front of middle, broadly rounded in front, with distinct nearly 

 regular serrations, slightly more than the cephalic half armed with 

 well developed asperities arranged in concentric nearly regular 

 rows; summit prominent; posterior area shining, with rather 

 numerous moderate sized punctures, except on the impunctate 

 slightly elevated area in the median line; basal marginal line dis- 

 tinct and continued diagonally downward along the sides as a mar- 

 gined ridge easily distinguishable to a point anterior and dorsal to 

 the base of the prothoracic leg. Ventral surface of the prothorax 

 punctured in front, smooth behind except immediately adjacent 

 to the base of the leg. 



Elytra of same width as prothorax; sides subparallel, widest 

 before the middle, slightly narrowed behind the middle to the level 

 of the origin of the declivity, from which point it is strongly and
