322 MEMOIRS ON THE COLEOPTERA 



just visibly shorter than wide, the converging sides from base to 

 apex very broadly and feebly angulate at the middle; concentric 

 incised lines of the pygidium uneven but throughout much more 

 widely separated than in sepulchralis, the umbo of the male strong 

 and well below the centre. Length (cf) 12.2 mm.; width 7.0 

 mm. Kansas (Medora). Probably a local race in this zoologic- 

 ally somewhat isolated region cuprascens n. subsp. 



Body oblong-oval, much shorter than in any of the above and with finer 

 and denser sculpture, piceous, very moderately shining, polished and 

 submetallic beneath; pubescence short and erect, rather abundant 

 on the pronotum, equal in length but very much sparser on the 

 elytra; head and clypeus of nearly the same form and sculpture as in 

 the preceding types, but the apex is transversely rounded, the sinus 

 almost completely obsolete; antennal club distinctly shorter than the 

 stem in both sexes; prothorax much shorter than wide, with arcuate 

 converging sides, the punctures strong and close-set, the median 

 line impunctate, sometimes slightly tumid; lateral tomentose stripe 

 generally comminuted; scutellum with scattered punctures except 

 basally; elytra barely longer than wide (cf), evidently so (9 ), the 

 costae distinct, smooth, the intervals with dense interlacing arcuate 

 umbilicate sculpture, the posterior concavity very densely reticulate; 

 flanks with the incised transverse lines deep, much broken up and 

 very dense; tomentose spots and lines nearly as in sepulchralis; 

 pygidium with very dense and confused incised sculpture, with 

 more or less comminuted tomentum basally as a rule, the pubescence 

 short, though notably long in one male from Asheville; male umbo 

 nearly at the centre; anterior tibial teeth nearly similar in the sexes 

 and equidistant or virtually so. Length (6 of) 9.6-11.0, (i 9 ) 12.2 

 mm.; width (cf) 5.8-6.8, (9) 7.0 mm. Maryland to northern 



Alabama. Not abundant appalachia n. sp. 



Body narrower and more rhomboidal, the smallest of this section, pale 

 piceo-rufous in color, not evidently metallic, moderately shining, 

 polished beneath, the legs paler and subcupreous; pubescence as in 

 the preceding; head nearly similar but with still more broadly 

 rounded clypeal angles and rather more evident, though vestigial, 

 sinus; antennal club small in both sexes; prothorax of the same 

 general form but less abbreviated, coarsely and densely punctate, 

 excepting the usual median line, which however is generally puncture- 

 less and also sometimes tumescent only behind the middle; sides 

 seldom even with disintegrated tomentum; scutellum generally more 

 punctured parallel with the sides except basally; elytra narrower, 

 distinctly elongate, the sculpture strong and close but less dense 

 than in appalachia and with more evident longitudinal incised lines 

 suturally, the tomentose spots and lines fine; pygidium with coarse 

 and deep, very irregular but less dense incised lines, with comminuted 

 tomentum basally or not, the male umbo below the centre; anterior 

 tibial teeth large, triangular, subsimilar in the sexes and subequi- 

 distant. Length (cf 9 ) 8.8-n.o mm.; width 4.9-6.2 mm. North 

 Carolina to Florida. Very abundant. Twenty-six examples.
