three. The species, which appear to be purely nearctic, are 

 moderately numerous and recognizable as follows: 



Basal joint of the anterior tarsi (9) not evidently broader than the 

 second 2 



Basal joint (9) dilated, much wider than the second. (Gynandro- 

 tarsiis Laf.) 13 



2 Pronotum broadly flattened, rugulose and strongly though not very 

 densely punctured latero-basally. Body subparallel, rather convex, 

 deep black when mature, shining, the elytra alutaceous (cf) or 

 densely opaque (9 ); under surface and legs black; antennae rather 

 stout, scarcely extending to the thoracic base, black, the first two 

 joints rufescent; palpi piceous, paler apically; head barely half as 

 wide as the prothorax, the eyes very moderate, the fovese small, 

 elongate-perforate, with attendant feeble impression of the surface; 

 prothorax two-fifths wider than long, the sides broadly rounded, 

 gradually more converging anteriorly, the apex deeply sinuate and 

 much narrower than the rectilinear base, the basal angles obtuse and 

 evidently rounded; surface smooth, rapidly declivous to the broad 

 concave horizontal and opaculate margins, which expand basally 

 into a perfectly flat surface; fovese large but extremely feeble, separ- 

 ated from the flat sides by a feeble convexity, all closely punctate; 

 stria subentire, fine anteriorly, stronger basally as a rule; elytra very 

 slightly wider than the prothorax, one-half longer than wide, broadly 

 ogival at apex, the sinus broad and extremely feeble, almost ves- 

 tigial; striae fine, the scutellar long, the intervals feebly convex or 

 barely at all so (9), the side margins and apex with excessively 

 minute punctulation bearing small hairs; third interval behind the 

 middle with two punctures on each elytron near the second stria; 

 abdomen with rather close punctulation bearing somewhat long 

 hairs medially at base; anterior tarsi (cf) very broadly dilated, the 

 second joint almost twice as wide as the first. Length (cf 9 ) 11.4- 

 13.0 mm.; width 4.4-5.2 mm. Long Island to Missouri. [Aniso- 

 dactyliis luctuosns Dej. and rnfipennis Lee.] carbonarius Say 



Pronotum smooth and not strongly or abruptly deplanate latero-basally . 3 



3 Upper surface opaculate in both sexes 4 



Upper surface very strongly shining throughout, at least in the male. . II 



4 Third interstrial interval as a rule with two or more substrial punc- 

 tures behind the middle 5 



Third interval with a single substrial puncture, excepting a few very 

 near the apex 10 



5 Upper surface moderately convex, the prothorax evenly and usually 

 rather strongly narrowed from base to apex 6 



LIpper surface strongly convex, the prothorax subparallel basally, ar- 

 cuately narrowing apically 9 



6 Prothorax shorter, the sides arcuato-convergent from base to apex. .7 



Prothorax much less transverse, the sides at first feebly, then more 

 strongly, converging anteriorly, head much larger 8 



7- Form oblong-oval, rather brownish-black, the latero-basal parts of 

 the prothorax somewhat pallescent from diaphaneity; under surface
