308 MEMOIRS ON THE COLEOPTERA 



angles right, sharp; basal transverse impression obsolete, the ante- 

 rior feeble and marked with short longitudinal strides ; stria very fine, 

 not impressed; foveae deeply impressed; surface wholly impunctate; 

 elytra nearly one-half longer than wide, about as wide as the pro- 

 thorax, the sides rather rapidly rounding behind; lateral series 

 widely and irregularly spaced but not definitely interrupted medi- 

 ally; striae fine, scarcely at all coarser apically, impunctate, the 

 seventh almost completely obliterated, the scutellar rather short, 

 fine, oblique, free at tip; intervals perfectly flat: middle tibiae (cf ) 

 obtusely, angularly bent within at the middle. Length (cf) 6.0 mm.; 

 width 2.5 mm. New Mexico (Fort Wingate), Shufeldt. 



wingatei n. sp. 



Prothorax short and transverse, three-fourths to four-fifths wider than 

 long ^ .27 



27 Elytra with the sides gradually rounding and obliquely converging 

 behind from before the middle. Body stout, convex, obscurely 

 bronzed above, moderately shining, the elytra ( 9 ) alutaceous, with 

 strong micro-reticulation; under surface piceous-black, shining; legs 

 dark and uniform rufous throughout; head barely half as wide as 

 the prothorax, with rather prominent eyes and short, very oblique 

 strioles; antennae short, not very slender, piceous, excepting the 

 three basal joints; prothorax three-fourths wider than long, the 

 sides broadly arcuate, straighter and parallel in about basal half; 

 apex three-fourths as wide as the base, evenly, rather deeply sinu- 

 ate, with bluntly rounded angles, the basal right; surface wholly 

 impunctate, the impressions subobsolete, the foveae deeply impressed, 

 the inner inclosing anteriorly the usual short incised line; elytra 

 two-fifths longer than wide, near the middle slightly wider than 

 the prothorax; apex narrowly but obtusely subprominent; lateral 

 series not interrupted; striae and flat intervals nearly as in the pre- 

 ceding. Length (9) 6.8-7.0 mm.; width 2.8-2.9 mm. Colorado 

 (Boulder Co.), L. W. Casey oviformis n. sp. 



Elytra with the sides rapidly rounding from distinctly behind the middle; 

 body less oval and more oblong 28 



28 Elytra near the middle slightly wider than the prothorax, very evi- 

 dently in the female but barely in the male. Body rather stout, 

 oblong-oval, narrower in the male, bright bronze to greenish-metallic 

 above; under surface greenish-black; legs obscure rufous, the femora 

 slightly piceous; head half as wide as the prothorax, with rather prom- 

 inent eyes and short, very oblique strioles; antennae notably short, 

 the joints obconic and feebly compressed, fusco-testaceous, the first 

 three joints paler; prothorax throughout nearly as in the preceding, 

 except that the median stria is coarser and impressed; surface appar- 

 ently never with a trace of the peculiar punctuation observable in 

 the following two species; elytra short, scarcely two-fifths longer 

 than wide; striae fine, not materially coarser behind, the seventh 

 subobliterated, the scutellar moderate, broadly free at tip as a rule; 

 intervals flat or very nearly; lateral series not interrupted. Length 

 (cf 9 ) 5.7-7.3 mm.; width 2.2-3.2 mm. Lake Superior (Marquette 

 and Duluth). Abundant convexa Lee.
