a rule, except medially. Excepting longicornis Say, the species occur 

 only in very cold climates; those before me are in great part unde- 

 scribed hitherto and may be known as follows: 



Frontal sulci long and deep, coarsely impressed 2 



Frontal sulci very short and feeble, almost obsolete 4 



2 Anterior transverse impression of the pronotum coarse, deep, groove- 

 like and impunctate. Body larger, broader and more convex, pol- 

 ished; head three-fourths as wide as the prothorax, with very prom- 

 inent eyes; last palpal joint two-fifths longer than the third; basal 

 constriction scarcely punctate; prothorax nearly one-half wider than 

 long, cordate, the sides evenly and moderately reflexed throughout 

 the length, sinuate basally, the basal angles not rounded, the apical 

 rather broadly; stria deep, coarsely sulciform at base; foveae large, 

 deep and cavernous, the carina feeble; elytra widest slightly behind 

 the middle, the striae coarse, very deep and strongly punctate, rap- 

 idly obsolete laterally; under surface piceous, the legs notably pale 

 flavo-testaceous. Length (cf 9 ) 11.0-13.5 mm.; width 3.9-4.8 mm.

 luth. Abundant. [Feronia longicornis Say; P. americanus Dej.] 



longicornis Say 



Anterior impression coarsely and diffusedly punctate; body much smaller 

 and narrower, the elytral stria? finer and less impressed, the legs 



darker 3 



3 Color black, the elytra obscure rufous, darker basally; under surface 

 rufous, blackish anteriorly, the legs dark rufous, the femora some- 

 times darker; elytra less shining in the female; head four-fifths as 

 wide as the prothorax, with very prominent eyes and small rounded 

 mandibles; basal constriction diffusedly punctate; antennae dark ru- 

 fous, sometimes piceous basally, rather long and slender, fully half as 

 long as the body in the male; prothorax a third (c/ 1 ) to one-half (9 ) 

 wider than long, widest two-fifths from the apex, the sides rounded, 

 becoming strongly sinuate, then parallel, basally, the angles sharp 

 but not prominent, the margins well reflexed, more narrowly toward 

 apex; anterior impression shallow but with numerous coarse diffused 

 punctures, the stria coarsely sulciform at base; foveae deep, coarsely 

 punctate, bistriate, the carina sharply marked; elytra oblong-sub- 

 oval, widest behind the middle, two-thirds longer than wide and 

 nearly one-half wider than the prothorax; apex gradually rounded; 

 sides but just visibly arcuate, rapidly rounding for a short distance at 

 the humeri; striae rather fine, bill slightly impressed suturally and 

 distinctly punctured except apically, where they become gradually 

 very fine, the seventh fine but distinct, the eighth moderately coarse; 

 third interval with three punctures. Length (cf 9 ) 9.5-10.5 mm.; 

 width 2.8-3.3 mm. Labrador (W. St. Modest), Sherman. Two 



examples labradorinus n. sp. 



Color black, slightly rufescent posteriorly beneath, the legs dark rufous; 

 body smaller and narrower than in the preceding, the head similar 

 but with smaller and scarcely so prominent eyes and with the man-
