260 MEMOIRS ON THE COLEOPTERA 



mm. Colorado (Boulder Co. and Eldora) and New Mexico (Las 

 Vegas). Twenty-five specimens terrestris Lee. 



Body somewhat as in terrestris but much smaller and relatively somewhat 

 narrower, nearly similar in coloration and lustre; elytra of the female 

 but little less shining than in the male; head relatively very much 

 larger, three-fifths as wide as the prothorax, the eyes very moder- 

 ately convex, the strioles convergent; antenna? much shorter, ex- 

 tending to about the thoracic base and ferruginous; prothorax less 

 transverse, one-half wider than long, nearly as in terrestris through- 

 out, but with the apex relatively less narrowed, being almost four- 

 fifths as wide as the base; punctures in the foveal region still smaller 

 and less numerous as a rule; elytra almost as in terrestris throughout, 

 but relatively somewhat shorter when compared with the prothorax, 

 two-fifths longer than wide, the striae deep, only moderately fine, 

 sometimes feebly punctate though often completely punctureless; 

 middle tibiae distinctly bent in the male. Length (cf 9 ) 6.5-7.0 

 mm.; width 2.65-3.1 mm. New Mexico (Jemez Springs) and Kan- 

 sas. Thirteen examples defecta n. sp. 



Body almost as in terrestris in form and size, similarly colored, the legs 

 and epipleura pale rufous; elytra more strongly alutaceous in the 

 female, subopaque; head similar but relatively somewhat larger, 

 distinctly more than half as wide as the prothorax, the eyes very 

 moderately convex, the strioles distinct, slightly oblique; antennae 

 flavo-ferruginous, extending slightly behind the prothorax (cf), 

 or to the thoracic base ( 9 ) ; prothorax throughout nearly as in ter- 

 restris, the elytra also as in that species, but the striae are rather finer 

 and deep, groove-like, and are distinctly punctulate in the female, 

 though scarcely visibly so in the male and more distinctly toward 

 the suture as usual; middle tibiae of the male extremely feebly bent 

 in the middle. Length (cf 9 ) 6.5-7.6 mm.; width 2.8-3.2 mm. 

 Oregon (Columbia River Valley), Shantz exposita n. sp. 



Body smaller and narrower than in terrestris, similar in color and lustre, 

 the pronotum at the sides more broadly diaphanous and rufescent; 

 upper surface polished throughout in the male; head much more 

 than half as wide as the prothorax, the eyes rather large and strongly 

 convex, more prominent than in terrestris, the strioles moderate and 

 slightly converging; antennae uniformly rufo-ferruginous, extend- 

 ing well behind the prothorax, the latter throughout almost as in 

 terrestris in outline and sculpture, except that the apical angles are 

 more broadly obtuse at tip, the basal foveae much deeper and the 

 punctures of the foveal region coarser and more numerous; both 

 foveae envelop the basal margin, the surface separating them notably 

 elevated; elytra as in terrestris but a little shorter, narrower and with 

 the parallel sides rather more arcuate, the similarly rather fine but 

 groove-like striae very obsoletely punctulate in some individuals; 

 intervals flat or nearly so; abdomen with a few punctures at the sides 

 of the first segment; middle tibiae of the male evidently bent. Length 

 (c?) 6.8-7.2 mm.; width 2.55-3.0 mm. Rhode Island (Boston Neck).
