114 CASEY 



black in all examples at hand; prothorax short, very nearly twice as wide 

 as long, feebly impressed along the middle, the subbasal fovea well 

 developed, the sublateral impressions feeble ( c?), or deep and conspicu- 

 ous ( 9 ), also sometimes with two additional submedial feeble impres- 

 sions in the former, which are obsolete in the latter, sex, where however 

 a small oblique impression is visible near the base at lateral fourth ; punc- 

 tures strong, unevenly dense laterally; elytra shorter than in patruelis 

 though much more than twice as long as wide, much more distinctly 

 wider than the prothorax, with a tendency to post-medial inflation, the 

 sides behind obliquely and subrectihnearly converging, the apices very 

 feebly sinuate and with broadly rounded or obtuse external angles; 

 surface nearly as in patruelis, generally immaculate but occasionally 

 with small post- median spots, especially in the female; under surface 

 similar. Length 13. 5-16.0 mm.; width 4.7-6.0 mm. Colorado (Boul- 

 der Co.) graminea n. sp. 



Form less elongate, similarly depressed, deep and uniform more brilliant 

 green above, cupreous and shining beneath, becoming greenish at the 

 sides anteriorly; legs bright green; head finely, very densely, subuni- 

 formly punctato-rugulose; eyes prominent, pale; prothorax as in gram- 

 inea but rather more narrowed anteriorly, the apex deeply and evenly 

 sinuate; surface narrowly, feebly impressed along the median line and 

 with a strong rounded impression toward each side at basal third, 

 strongly punctate, coarsely and very confluently so laterally; disk 

 coerulescent medially, as also in a broad area along the elytra! suture 

 disappearing toward tip; elytra scarcely more than twice as long as 

 wide, about a fourth wider than the prothorax, somewhat abruptly, 

 strongly, subrectihnearly narrowed in nearly apical two- fifths; surface 

 with the sulci not quite so coarse but confusedly and closely punctate, 

 the intervals much wider than the sulci, finely, remotely punctate, each 

 elytron with a transverse sinuous pale spot and a small and very obUque 

 subapical spot nearly as in fasciata, the spots surrounded by a black 

 clouded border; punctures of the under surface stronger than in the 

 preceding species but not conspicuous; basal segment of the abdomen 

 very faintly impressed medially as usual in this section. Length 14.7 

 mm. ; width 5.5 mm. Lake Superior (Isle Royale) saturata n. sp. 



"Elytra like aurulenta; prothorax flattened, side margin thickened, disk with 

 a broad dorsal stripe, and obUque space each side smooth; prothorax 

 and under surface thinly clothed with long soft white hair. CaUfor-

Some of the synonymy suggested by Crotch and since perpetuated 

 in catalogues, is of so extraordinary a nature that it is difficult to ac- 

 count for it as a deliberately formulated scientific opinion; perhaps 

 the most completely untenable of these suggestions is that which 

 unites such diverse forms as langi and sexplagiata with fasciata. The 

 species described under the name connexa, by G. H. Horn, is only
