to be noted so far as observed. In Nothopus the serial punctures 

 of the elytra are relatively much smaller than in Piosoma and they 

 are less numerous, but the setae borne by them are similarly long 

 and bristling; the punctures of the pronotum are fine. There are 

 undoubtedly a number of distinct species, those represented in my 

 cabinet being as follows: 



Head notably large in both sexes, distinctly more than half as wide as 

 the prothorax. Body large in size, very stout, oblong-oval, convex, 

 shining, black to rufo-piceous, the legs, under surface, antennae and 

 palpi paler and obscure rufous, the labrum nearly black; head scarcely 

 at all punctulate, the impressions long, parallel, broadly and feebly 

 impressed, uneven and rugulose, the surface between them also 

 rugulose medially; labrum large, feebly sinuate medially, with 

 broadly rounded angles; eyes very moderate; antennae rather slender, 

 compressed, extending barely to the middle of the prothorax, the 

 third joint but little longer than the second or fourth; prothorax 

 nearly twice as wide as long, parallel, almost equal in width to the 

 elytra and compactly joined throughout the basal width, the humeri 

 only minutely exposed, the sides straight, slightly rounding anteriorly, 

 the basal angles not rounded and feebly subeverted; base broadly, 

 feebly sinuate in median half, margined throughout, the apex feebly 

 bisinuato-truncate, the fine margin broadly interrupted medially; 

 surface steeply declivous at the sides to the conspicuous and coarse 

 marginal gutter, which expands basally, the edge strongly re flexed 

 from apex to base; toward base and apex throughout the width with 

 rather sparse, fine and very distinct punctures; median stria bi- 

 abbreviated but rather deeply impressed and distinct; foveae ob- 

 solescent; elytra a third longer than wide, two and two-thirds times 

 as long as the prothorax, subparallel, slightly swollen at the sides 

 near the base, broadly and obtusely ogival at apex, the sinus ob- 

 solete; basal margin straight, curving forward slightly to the 

 obtusely dentate humeri; striae fine, feebly (cf) or more strongly ( 9 ) 

 impressed, the intervals flat to feebly convex, barely more convex 

 behind, the scutellar stria long, the first symmetrically bifurcating 

 basally, as in all the subsequent species; punctures of intervals 

 3~5~7 very moderate, inconstant, widely and unevenly spaced; 

 intervals 468 also serially punctate toward apex as a rule; marginal 

 series uninterrupted and irregular; legs moderately long and stout, 

 the first four joints of the hind tarsi decreasing slowly and evenly in 

 length, the claws very slender and strongly arcuate. Length (cf 9 ) 

 12.015.8 mm.; width 6.47.7 rnm. Iowa (Keokuk) and Lake 

 Superior. Six examples valens n. sp. 



Head distinctly smaller, not more than half as wide as the prothorax in 

 either sex and similarly not differing much sexually 2 



2 Elytra barely perceptibly longer than wide, the punctures of the 

 alternate intervals larger, more impressed, more numerous and less 

 regularly serial in arrangement than in any other species. Head 

 nearly as in valens, the labrum still more feebly sinuate, obscure
