Elytra dark brown in color. Body larger, rather stout, black, moder- 

 ately shining, the elytra alutaceous in the female; under surface 

 black, the legs rufo-piceous; head two-thirds as wide as he prothorax, 

 the strides large, elongate and broadly impressed; antennae piceous, 

 the basal joint rufous; prothorax a little less than one-half wider 

 than long, as wide at base as at the deeply sinuate apex, widest at 

 about the middle, with evenly arcuate sides from apex to base; mar- 

 gins rather broadly reflexed and punctulate; foveae strongly punc- 

 tate, feebly half divided, the carinae strong; elytra one-half longer 

 than wide, barely visibly wider than the prothorax, the striae mod- 

 erate and with distinct punctures, the broad intervals nearly flat, 

 not more convex at apex. Length (9) 10.5 mm.; width 4.2 mm. 

 Labrador (Nain) brunnipennis Dej. 



Elytra rather bright rufous. Body smaller and distinctly more slender, 

 moderately shining, the elytra dullish, deep black, the legs virtually 

 black; head three-fifths or more as wide as the prothorax, the strioles 

 small, fine; antennae blackish, the two basal joints paler; prothorax 

 two-fifths to one-half wider than long, widest distinctly before the 

 middle, the sides similarly subevenly rounded to the base but much 

 more finely reflexed and less punctate; apex sinuate, with broadly 

 rounded angles; surface impunctate anteriorly, the foveae smaller 

 than in brunnipennis, coarsely punctate, the inner barely traceable; 

 carinae shorter and more obtusely convex; elytra two-thirds longer 

 than wide, a fifth or sixth wider than the prothorax, ogivally rounded 

 from slightly behind the middle, the striae fine and very finely punc- 

 tulate; intervals nearly flat; lateral series of ocellate punctures ex- 

 tremely widely interrupted. Length (cf 9 ) 7-8-9-5 mm.; width 

 2.75-3.75 mm. Colorado. Eleven examples rubripennis n. sp. 



Elytra not paler; upper surface uniform in color throughout 2 



2 Thoracic foveae small, only slightly elongate and completely isolated, 

 having but few punctures. Body rather elongate, only moderately 

 convex, blackish-brown and moderately shining, the under surface 

 and legs rufo-piceous; head two-thirds as wide as the prothorax, 

 with notably prominent eyes and small fine strioles; antennae pice- 

 ous, the one or two basal joints rufescent, moderate in length, stout, 

 with rather short joints; prothorax two-fifths wider than long, widest 

 before the middle, the rather finely reflexed sides as in the preceding; 

 apex shallowly sinuate but with less broadly obtuse angles; elytra 

 three-fifths longer than wide, a fifth or sixth wider than the pro- 

 thorax, parallel, with feebly arcuate sides; striae fine and more or 

 less finely punctate. Length (9) 8.0-9.5 mm.; width 3.0-3.5 mm. 

 New Hampshire (summit of Mt. Washington). Two examples. 



deficiens n. sp. 



Thoracic foveae larger and closely punctate, either wholly coalescent or 

 feebly divided 3 



3 Body narrow and very elongate, notably convex, deep black above 

 and beneath, the legs obscure rufous; surface moderately shining; 

 head two-thirds as wide as the prothorax, with prominent eyes and 

 small fine strioles; antennae fusco-ferruginous throughout, the joints 

 much more elongate than in deficiens, the medial on the edge fully
