332 MEMOIRS ON THE COLEOPTERA 



(cf 9) 9.3-11.2 mm.; width 3.2-3.7 mm. Female the smaller and nar- 

 rower. Colorado (Boulder Co., Leadville and Eldora) and Montana. 

 Eight examples. 



Hitherto considered by me to be the same as longulus Lee., and 

 so described in my former revision, but it differs in its paler color- 

 ation and minutely prominent basal thoracic angles; there are simi- 

 larly three joints of the hind tarsi grooved externally, but* the groove 

 of the third is rather faint. 



Hypherpes luscus n. sp. Body not quite so narrow and rather more 

 parallel than in restrictus, black, with feeble piceous tinge, the legs rufo- 

 piceous; integuments similarly sculptured and shining; head three-fifths 

 as wide as the prothorax, nearly as in the preceding, except that the eyes 

 are smaller and less prominent; antennae dark castaneous throughout, 

 the third joint only a fourth longer than the fourth and slightly shorter 

 than in restrictus; prothorax larger, a fourth wider than long, the sides 

 less strongly arcuate, and more evenly so, almost to the basal angles, 

 which are feebly prominent; base feebly sinuate medially, margined lat- 

 erally, much broader than in the preceding and about as wide as the 

 moderately sinuate apex; both impressions distinct, the ruguliform lines 

 distinct; there is also a faint transverse impressed line parallel with the 

 base; median stria short, deep; inner fovea rather short, not attaining 

 base, the outer short and very feeble, the carina wanting; elytra more than 

 three-fourths longer than wide, only just visibly wider than the prothorax, 

 abruptly and obtusely rounded at tip, with evident sinus, the sides very 

 feebly arcuate, the humeral denticles very minute; striae strong, moder- 

 ately impressed, not distinctly punctulate, the scutellar rather short and 

 fine but usually visible, the puncture wanting; intervals very feebly con- 

 vex; prosternum nearly as in restrictus. Length (cf 9 ) 10.0-11.5 mm.; 

 width 3.35-3.9 mm. Female smaller, narrower and much less abundant 

 than the male. Colorado. Seven specimens from the Levette collection. 



Also allied to longulus, but differing in the broader prothorax, 

 with minutely prominent basal angles and evident scutellar stria 

 said to be wanting in longulus. 



Hypherpes elumbis n. sp. Form shorter, with relatively broader and 

 more oval elytra, piceous-black; under surface piceo-rufous; legs colored 

 as in restrictus; lustre moderately shining; head elongate, three-fifths as 

 wide as the prothorax, with rather long neck, moderate and somewhat 

 prominent eyes and arcuate, converging sulci; antennae nearly as in 

 luscus; prothorax also as in luscus throughout in almost every particular, 

 except that it is relatively smaller in size; elytra shorter, barely two-thirds 

 longer than wide, nearly a fourth wider than the prothorax, less abruptly 

 rounded behind, the parallel sides more arcuate, the sinus rather fainter, 

 very feeble, the humeri similar; striae finer than in the preceding, not 

 evidently punctulate, the scutellar short, oblique and fine, without punc- 

 ture; intervals feebly convex; prosternum nearly similar. Length (9)
