1 82 MEMOIRS ON THE COLEOPTERA 



with rather narrowly rounded angles and much narrower than the 

 base; surface deplanate and closely punctured at the sides, finely 

 anteriorly, more broadly basally, the foveae very large, shallow, 

 rounded and closely punctate, the punctures continuous with those 

 of the sides; stria distinct, attaining base but not the apex; elytra 

 equal in width to the prothorax (cf ) or distinctly wider (9 ), rather 

 less than one-half longer than wide, gradually obtusely ogival 

 posteriorly, the sinus very feeble but evident; striae fine and shallow, 

 the scutellar long, the intervals flat or nearly so, without punctula- 

 tion of any sort, the discal puncture near apical third and frequently 

 widely detached from the stria; hind tarsi with the basal joint dis- 

 tinctly shorter than the next three, extremely finely and sparsely 

 punctulate above. Length (cf 9 ) 11.0-12.0 mm.; width 4.2-4.9 

 mm. North Carolina (Asheville) to Missouri (St. Louis) . . furvus Lee. 



Elytra apparently opaque in both sexes; size very much larger than in 

 any other species and also differing from any other in having no 

 substrial elytral puncture. Body black; epistoma with a single 

 puncture at each angle; head larger in the female than in the male: 

 prothorax at base narrower than the elytra; apex and base nearly 

 equal in width, the sides arcuate, the hind angles obtuse and 

 rounded; lateral margin rather widely depressed and densely punctu- 

 late; foveae large; surface almost smooth, finely punctate near the 

 apical margin, more coarsely along the basal; elytra feebly arcuate 

 at the sides, the striae impressed but not punctate; intervals convex, 

 not punctulate; mentum, ligula, paraglossae, anterior tibial spur and 

 the male tarsi as in the other true Anisodactyli; hind tarsi slender. 

 Length 18-19.5 mm. Alabama (Mobile) lodingi Schf. 



Elytra polished in the male, feebly alutaceous in the female, the surface 

 more convex; epistoma having .two setigerous punctures at each 

 angle as a rule 6 



6 Body oblong-oval; head with short narrow and sublinear foveae, the 

 eyes somewhat prominent but very moderate in size as usual ; antennae 

 slender, nearly black, the basal joint testaceous but partially clouded 

 with blackish; prothorax one-half wider than long, the sides very 

 evenly and rather strongly arcuate, the apex moderately sinuate, 

 with rather broadly rounded angles and evidently narrower than the 

 base; surface somewhat as in furvus, excepting that the sides are 

 more steeply declivous to the explanate margins, which, with the 

 latero-basal surface, is more coarsely and sparsely punctate, much 

 less broadly flattened laterally at base but more broadly so anteriorly, 

 the foveae less broad though feeble and separated from the depressed 

 sides by a more pronounced convexity; stria fine, almost entire; 

 elytra subequal in width to the prothorax in both sexes, in outline 

 nearly as in furvus but much more convex and more abruptly, 

 obtusely ogival at apex, the sinus a little less feeble and very distinct; 

 striae fine but very deep, the intervals strongly convex, especially 

 toward the suture, the discal puncture strong, near three-fifths; 

 minute, sparse, suffused punctulation barely traceable, obsolete; hind 

 tarsi as in furvus. Length (cf 9 ) 10.2-13.0 mm.; width 4.0-4.8 

 mm. Rhode Island to Nebraska.. harrisi Lee.
