n6 MEMOIRS ON THE COLEOPTERA 



intervals moderately convex, the third unipunctate posteriorly; 

 middle tarsi (cf ) not much dilated but with a double series of papillae 

 beneath as in the other species. Length 12.5 mm.; width 5.2 mm. 

 Near Long's Peak funestus Lee. 



Elytra ( 9 ) with the sutural angles briefly spinulose 3 



3 Head larger, nearly two-thirds as wide as the prothorax; mentum 

 tooth rather strong but distinctly obtuse. Atlantic regions 4 



Head more moderate, never more than three-fifths as wide as the pro- 

 thorax; mentum tooth very short, more or less feeble and broadly 

 rounded. Pacific regions 5 



4 Form broad and feebly convex, oblong-suboval, rather shining, the 

 elytra (9 ) densely sericeo-opaque; body piceous in color, dark red- 

 brown beneath, the legs piceo-rufous; cephalic appendages testaceous; 

 head smooth, with moderate and rather prominent eyes and small 

 perforato-punctiform fovese; antennae slender, shorter ( 9 ) ; prothorax 

 three-fourths wider than long, the sides broadly arcuate anteriorly, 

 feebly converging and subsinuous thence to the base, which is 

 transverse, finely and strongly margined and evidently wider than 

 the apex, which is broadly sinuate, with not very broadly rounded 

 angles, the basal angles strongly defined, but little more than right, 

 with the tips only very narrowly blunt; surface feebly convex, steeply 

 sloping to the very finely reflexed edge anteriorly, the gutter widen- 

 ning posteriorly and nearly flat, opaque but scarcely at all punctate 

 and disappearing in the broad latero-basal flattening in basal third, 

 this region more alutaceous than the rest of the surface and with 

 minute sparse punctules, the foveae short, moderately deep, rugulose, 

 opaque and punctulate; elytra less than one-half longer than wide, 

 gradually ogival at tip, parallel, with broadly arcuate sides and almost 

 a fourth wider than the prothorax; sinus broad, even and distinct and 

 with a second short sinus next t,o the sutural spine; striae fine, feeble, 

 the scutellar long, the intervals ( 9 ) perfectly flat, the puncture fine, 

 on the second stria near apical third; metasternum laterally moder- 

 ately opaque and finely, sparsely punctate; hind tarsi with the first 

 joint equal in length to the fifth, the third two-thirds longer than 

 wide. Length (9) 13.4 mm.; width 5.6 mm. Michigan (Mar- 

 quette) lewisi Lee. 



Form in general similar but still broader and more parallel, deep black 

 above and beneath, the legs black, the anterior and middle tarsi (cf ) 

 piceo-rufous; upper surface (cf) extremely polished throughout, 

 or (9) shining, the pronotum slightly alutaceous latero-basally 

 and the elytra densely sericeo-opaque; head and antennae nearly as 

 in lewisi; prothorax similar throughout, except that the latero-basal 

 flattened region is more strongly and closely punctured throughout 

 and that it is more nearly as wide as the elytra, the latter almost 

 similar, except that the sinuses at tip are feebler and that they are 

 only about two-fifths longer than wide, rather more obtuse at apex 

 and less than a fifth wider than the prothorax; metasternum ( 9 ) at 

 the sides more densely opaque, more rugose and more strongly 

 punctured; hind tarsi (9) similar, except that they are slightly 

 more elongate. Length (cf 1 9 ) 13.3-14.0 mm.; width 5.2-5.9 mm.
