NORTH AMERICAN COLEOPTERA. 271 



C. moratus n. sp.-Oblong, snbdepressed, pi.eous black, surface will, a verv 

 taint bronze lustre. Antenna, fl-jointed, testaceous at base, club piceous Head 

 moderately coarsely and closely punctate, tbe intervals very distinctly alutace- 

 ous. Thorax moderately, coarsely and closely punctate, more finelv on the disc 

 intervals alutaceous. Elytra oblong parallel, sutural stria distinctly impressed 

 two-thirds to ba.se. surface shining, not alutaceous, punctuation coarser, but not 

 closer than on the thorax, and when viewed longitudinally, especially near the 

 apex, exhibiting a tendency to form rows. Body beneath piceous, opaque Leg. 

 entirely p.ceons. Posterior femora faintly strigose, sparsely punctate, middle 

 and front femora pubescent and opaque, except at tip. Length .12 inch. ; 3 mm. 



Prosternum simple, niesosternum without trace of elevation. 



Maxillary palpi piceous, stout. Claws slender, simple and feebly 

 curved. 



This species may be readily known from either disswiilis or vion- 

 hcola by Its entirely piceous thorax, and while it has the head and 

 thorax distinctly alutaceous as in monticola, it has the 9-jointed an- 

 tenna? of dissimilis. 



Three specimens collected in Utah were kindly given me by Mr 

 Charles W. Strumberg. 



€. monticola n. sp.-Oblong oval, snbdepressed, piceous ; elytra ochraceous 

 or pale brown, thorax with pale border at apex, sides and base externally (PI iv 

 ftg. loi. Head entirely piceous, finely but not closely punctate, interspaces ex- 

 tremely minutely alutaceous. Antenna. 8-jointed ,P1. iv, fig. 17), testaceous 

 club p.ceous. Thorax three times as wide as long, moderately coarsely, but not 

 very closely punctate, the intervals distinctly alutaceous, basal marginal line 

 entirely absent. Elytra oval, sides arcuate, disc more coarsely punctate than the 

 thorax, coarser near the apex, but more sparse, the punctures seen in a lono-itu- 

 dinal direction giving the vague appearance of stride, especially near the sides 

 Body beneath piceous, opaque. Femora piceous, tibiae and tarsi rufo-testaceous' 

 femora punctulate, pubescent and opaque, except near the apex, the posterior 

 pair, however, less opaque than the others. Length .10-.14 inch. ; 2.5-3.5 mm 



Prosternum and niesosternum entirely simple. Maxillary palpi 

 short and moderately stout, the basal joint not especially thickened 

 (PI. iv, fig. 12). Claws slender and simple. 



This species has been supposed to be identical with dissimilis, and 

 as far as color goes, fits the description better than the mature speci- 

 mens of that species. It differs superficially in color, the elytra beino- 

 always ochraceous, the number of joints of the antennae and the 

 form of the pseudo-basal joint of the maxillary palpi. The apical 

 margin of the thorax is here always with a pale border, never so in 

 disswiilis, except when the specimens are palpably immature. 



Occurs abundantly in the White Mountain region of New Hami)- 

 shire. I have one from Pennsylvania.
