THE CANADIAN ENTOMOLOGIST. 315 



Pachybrachys Nero, nov. sp. — Same size and shape as truncatus, 

 Bow., but dull whitish-yellow and nearly regularly punctate striate. 

 Length, 23^ mm. 



Head convex, yellow, with darker vertex, and central line and spots 

 at the base of the antennas, which reach about the middle of the abdomen 

 (^ ), eyes distant, thorax wider than long, gradually narrowed to the front, 

 with a well-marked antescutellar lobe and with the posterior margin some- 

 what thickened, moderately and finely brown punctate, one specimen with 

 a well-marked brown M, the, other specimen with the M very faintly 

 indicated, sides feebly angulate ; elytra dull yellow, almost regularly 

 punctate striate, the brown punctures slightly thicker and confused 

 in the two short scutellar striae, and showing a tendency to become 

 biseriate in the anterior parts of the first four or five striae, the sutural and 

 third and fourth intervals from about the middle are much widened 

 posteriorly and present the appearance of smooth, flat, longitudinal stripes ; 

 one of the specimens has a faint suspicion of one or more of the standard 

 spots, but not prominent ; marginal stria feebly rounded about the 

 humerus, and in one specimen it might be called feebly subangulate, and 

 barely sinuate behind, lobe moderate, with a row of fine marginal punc- 

 tures, body below brown, with epimera, legs, sides of abdomen and 

 pygidium yellow.

Pachybrachys Sevier, nov. sp. — Medium sized, shining dirty-yellow, 

 almost regularly brown punctate striate. Length, i x /£-2^ mm. 



Head yellow, front lightly convex, punctured, with dark spots at base 

 of antennas, faint frontal and vertex marks, antennae darker, with light 

 basal joints, barely one-half as long as body in °. , eyes very distant, 

 thorax broader than long, shiny yellow, with rather large brown punctures 

 diffused over its surface, M at most only very fainly indicated by clouds, 

 transverse depression fairly well marked, lateral edge subangulate ; elytra 

 shiny yellow, regularly brown punctate striate, except that the scutellar 

 area is confused, in one example there seems to be a tendency to have the 

 third and fourth intervals widen at the convexity, marginal stria both 

 lightly curved and sinuate behind, lobe fairly developed with a row of 

 punctures, body below dull black, with the epimera, last segment and 

 pygidium yellow, legs red-brown, with lighter bases to the femur ; fossa
