deeply sinuate; elytra more oblong, with slightly less arcuate 

 sides, three-fifths wider than the prothorax; legs pale. Length

statenensis n. subsp. 

 Body ventriculate as in the preceding but very much smaller, deep black 

 and highly polished throughout, the under surface not less polished 

 at the sides. Epipleura piceo-rufous, the legs clear and very pale 

 rufo-flavate; head scarcely longer than wide, with rather prominent 

 eyes, fully three-fourths as wide as the prothorax; antennae slender, 

 rather more than half as long as the body, piceo-testaceous, the first 

 three joints very pale and clear testaceous; prothorax nearly as long 

 as wide, peculiar in outline, the sides evenly and moderately arcuate 

 throughout and slightly converging from near the apex to the 

 broadly rounded basal angles, the base evidently narrower than the 

 very feebly sinuate apex; apical angles unusually deflexed; basal 

 foveae small and punctiform, very deep, slightly and more shallowly 

 prolonged; elytra barely one-half longer than wide, three-fourths 

 wider than the prothorax, gradually ogival behind the middle, 

 the parallel arcuate sides rapidly rounded at base; striae coarse, not 

 very deeply impressed but coarsely and very conspicuously punctate 

 not quite to the apex, the lateral striae virtually simple series of 

 almost equally strong punctures; intervals broadly convex; met- 

 episterna small, not quite one-half longer than wide; anterior male 

 tarsi narrowly but evidently dilated. Length (cf ) 7.0 mm.; width 



2.65 mm. Iowa (Iowa City), — Wickham liticola n. sp. 



Body narrower and very much less ventricose than in the two preceding; 

 under surface similarly polished and not at all opaculate laterally. . . 7 

 7 — Prothorax smaller, much less than three-fourths as wide as the elytra, 

 the dorsal punctures of which are three, situated on the third interval 

 as usual; upper surface deep black, rather convex, polished; head 

 barely at all longer than wide, fully two-thirds as wide as the pro- 

 thorax, the eyes moderate in size and prominence; antennae very 

 slender, fuscous, paler basally, a little more (cf) to slightly less (9 ) 

 than half as long as the body, the third and fourth joints equal; 

 prothorax of the same general form and structure as in punctiformis, 

 the transverse impressions wanting; stria extremely fine and in- 

 complete; foveae small, deep, generally traceable for some distance 

 anteriorly by very feeble impression; elytra about one-half longer 

 than wide, one-half wider than the prothorax, gradually parabolic 

 behind, with very feeble sinus; humeri somewhat rapidly rounding; 

 striae coarse but only just visibly impressed, the coarse punctures 

 crenulating the feebly convex intervals, which are flat externally; 

 anterior male tarsi but feebly dilated. Length (cf' 9 ) 6.8-7.5 mm.; 

 width 2.25-2.8 mm. New Jersey to Indiana, Iowa (Keokuk) and 

 Lake Superior (Marquette). Rather abundant. The male is 



narrower than the female as usual ' crenistriata Lee. 



Prothorax and head much larger, the former about three-fourths as 

 wide as the elytra, the dorsal punctures of which are sometimes 

 irregular, in the type three to five on the third, and sometimes
