New York (Plattsburg). Five examples. Closely allied to lewisi 

 but apparently distinct aesopus n. sp. 



5 Outline oblong-suboval, more convex and narrower than the pre- 

 ceding, deep polished black above, the elytra opaculate (9 ); under 

 surface and legs very faintly rufopiceous-black in mature examples; 

 anterior and middle tarsi (cf ) slightly paler; head smooth, the eyes 

 moderate and rather prominent, the foveae small, perforato-puncti- 

 form; antennae slender but far from attaining the thoracic base In 

 either sex; prothorax one-half (cf) to three-fifths (9) wider than 

 long, the sides broadly rounded anteriorly, less rounded to nearly 

 straight and feebly converging posteriorly, the angles evidently more 

 than right, with their tips rather narrowly blunted; base transverse, 

 finely margined, feebly bisinuate, distinctly wider than the broadly 

 and strongly sinuate apex; surface steeply declivous anteriorly to 

 the moderately finely reflexed edge, the gutter finely rugulose, 

 gradually widening, curving slightly inward and becoming shallow 

 and inclined posteriorly and disappearing at basal third on the broad 

 and feeble, scarcely more alutaceous and usually though not always 

 punctureless latero-basal region; foveae short, rather shallow, sparsely 

 punctured, sometimes almost obsolete; elytra oblong, parallel, rather 

 abruptly very obtuse at apex, not quite one-half longer than wide 

 and but very little wider than the prothorax, the sides only very 

 feebly arcuate, the sinus feeble, deeper externally, where the limiting 

 projection is subprominently though rather broadly rounded; striae 

 fine, scarcely (cf ) or not (9 ) impressed, the scutellar notably long, 

 the intervals flat to very feebly convex; hind tarsi with the basal 

 joint not quite as long as the fifth. Length (cf 9 ) 10.4-13.4 mm.; 

 width 4.2-5.5 mm. New Mexico, Colorado and Arizona. Very 

 abundant. Forty-nine examples. [//. oblitus Lee. nee Dej.]. 



lecontei nom. nov. 



Outline similar but always more elongate and larger in size, oblong, moder- 

 ately convex, polished black (cf) throughout above, the under 

 surface and legs black, the anterior and middle tarsi (cf ) scarcely 

 paler, piceous-black; antennae nearly similar but dusky, blackish 

 basally, the palpi blackish, pale at tip; head nearly as in the pre- 

 ceding; prothorax relatively shorter, fully three-fifths wider than 

 long in the male, the surface nearly as in the preceding, except that 

 the marginal gutter barely at all widens posteriorly and does not 

 turn inward, disappearing at basal third, the vicinity of the hind 

 angles more flattened, the anterior angles more narrowly rounded and 

 the basal still more sharply defined, being barely even at all blunted 

 at the apices, the sides anteriorly also are more strongly arcuate; 

 elytra more elongate, slightly more than one-half longer than wide, 

 nearly a fourth wider than the prothorax, with parallel and broadly 

 arcuate sides, the sinus of the same general form but still feebler, 

 the striae similar though generally a little more impressed and the 

 puncture similarly near apical third; hind tarsi differing distinctly, 

 being very much longer, with the basal joint fully as long as the 

 last. Length (cf) 12.5-14.5 mm.; width 5.2-5.6 mm. Utah and
