CETONIIN/E 323 



8 Form slightly rhomboidal, somewhat depressed above, shining, 

 brownish-testaceous in color, the anterior parts more piceous; under 

 surface and legs blackish, the abdomen subviolaceous, the femora 

 subcupreous; pubescence above nearly as in scolopacea, that of the 

 sterna rather long, abundant and conspicuous; head densely punc- 

 tate and pubescent, the clypeus nude and with the punctures not- 

 ably sparse, the apex abruptly slightly reflexed, evenly and obtusely 

 rounded, without trace of sinus; antennal club small; prothorax 

 nearly a third wider than long, trapezoidal, the sides a little more 

 arcuate medially; punctures rather large, moderately close, shallow 

 and crescentic, the median impunctate line entire; pubescence 

 abundant, coarse, yellowish and not very short; margin within the 

 bead with disconnected small spots of tomentum; scutellum with 

 scattered punctures toward the sides throughout the length, not very 

 finely acuminate; elytra with smooth elevated costse, the sculpture 

 of the intervals consisting of peculiarly comminuted confused inter- 

 lacing incised lines, very even but becoming sparser and more like 

 punctures basally, the flanks with deep interlacing transverse close- 

 set grooves; tomentose spots and lines fine, somewhat as in sepnlchralis, 

 with a row of small spots along the apical margin; pygidium moder- 

 ately convex, the incised lines irregular, fine, not dense and becoming 

 still finer and feebler toward the sides, the hairs short and sparse; 

 anterior tibial teeth strong and triangular, the lower two rather the 

 more approximate. Length ( 9 ) 10.3 mm.; width 6.0 mm. Indiana. 

 A single example oxysternum n. sp. 



9 Form oblong, the elytra parallel, shining, black and wholly unmetallic 

 above and beneath, the elytra yellow, with the base, a transverse 

 rhomboidal medial fascia, often broadly joining the basal fascia 

 suturally, and a transverse spot crossing the suture near the apex 

 and also often broadly united with the median fascia, black; ex- 

 ternally, at apical fourth, there is a small black spot though often 

 obsolete; pubescence cinereous, barely visibly straw-yellow, rather 

 variable on the pronotum, from very short to very long and shaggy, 

 more constant on the elytra, sparse but rather long and coarse, 

 wanting on the strongly elevated costae, long, very dense and con- 

 spicuous on the pygidium, except in an apical strigose area which is 

 completely glabrous, long and coarse but not very dense on the 

 sterna and sides of the abdomen; clypeus obtuse, not much reflexed 

 but distinctly sinuate medially at apex; prothorax unusually small, 

 much narrower than the elytra, the sides subparallel, oblique 

 anteriorly, rather strongly, densely punctate, a slightly tumid median 

 line joining a large medio-basal area and two irregular discal areas 

 at each side, smooth and punctureless; scutellum formed as usual, 

 smooth and punctureless; elytra a fourth to fully two-fifths longer 

 than wide, the depressions with rather close elongate incised annuli, 

 open behind, and also with some longitudinal incised lines; flanks 

 with smaller, transversely crescentic punctures, not closely placed 

 and with a smoother line near the sides; anterior tibiae sharply tri- 

 dentate in both sexes, the two lower teeth more approximte; an- 

 tennal club notably small in both sexes. Length (of 9 ) 11.0-14.5
