194 MEMOIRS ON THE COLEOPTERA 



sutural interval; pygidium with small but distinct and not very 

 sparse punctures throughout, subrugulose at the sides, in large part 

 covered by the elytra in the male; abdomen scarcely punctate later- 

 ally except in the usual close-set series of very fine punctures; post- 

 coxal plate smooth and polished, sparsely punctate basally and 

 minutely, densely so at apex. Length (cf ) 12.7-13.2 mm.; width 

 7.0-7.7 mm. Texas (Waco) parallelus n. sp. 



Body oblong-oval, more inflated behind and of stouter build 5 



5 Hind tibiae short, obconic, not very deeply sinuate externally near 

 the apex and only moderately expanded at the apex. Body rather 

 small in size, polished, dark piceo-castaneous in color above, the 

 under surface pale yellowish-ferruginous; pronotum rather paler at 

 the sides; head fully two-fifths as wide as the prothorax, blackish, 

 the clypeus bright rufous; front finely rugulose, feebly impressed 

 along the middle, the base smooth; carina finely acute along the 

 summit, which is feebly sinuate at the middle, not attaining the 

 sides; clypeus polished and with minute sparse asperities, the teeth 

 small, slender and spinuliform; prothorax short, two-thirds to three- 

 fourths wider than long, in outline nearly as in the preceding, except 

 that the basal angles are only narrowly rounded viewed dorsally; 

 surface very smooth and polished and with minute shallow punctures, 

 very remotely scattered, the pit well developed, smooth, gradually 

 shallowing laterally, steeper posteriorly, the tubercle rather strong 

 and acute; scutellum very smooth; elytra slightly elongate, more 

 than twice as long as the prothorax and, posteriad, distinctly wider, 

 the lines rather coarsely but moderately impressed, with the punc- 

 tures well spaced, coarsely impressed, each with an elliptic annulus, 

 the subsutural interval with rather few punctures; pygidium pol- 

 ished and remotely, obsoletely punctulate, punctured laterally and 

 basally ( 9 ), or with fine rugulosity toward the sides (c?) : hind tibiae 

 but little more than twice as long as their apical width; hind coxal 

 plate finely but not densely punctate apically. Length (cf 9 ) 

 12.8-13.2 mm.; width 7.3-7.8 mm. New Jersey (Atlantic City). 

 Not common remotus n. sp. 



Hind tibiae longer, relatively more slender, more deeply sinuate externally 

 near the apex, which is more abruptly and strongly expanded. . . .6 



6 Prothorax larger, only moderately transverse, three-fifths to two- 

 thirds wider than long. Body stout, convex, shining, black when 

 mature, the under surface and legs castaneo-rufous; head barely more 

 than a third as wide as the prothorax, with fine, sparse rugulosity, 

 the base smooth and polished, the carina as in the preceding but with 

 the median sinu? nearly obsolete; clypeus rufescent, finely, loosely 

 asperulate, with the minute asperities becoming very dense apically 

 to the base of the teeth, which are strongly elevated, very acute and 

 less approximate than in many others; prothorax subparallel, with 

 the sides nearly straight viewed dorsally from the broadly 

 rounded basal angles nearly to apical third, where they become 

 strongly oblique to the apex; annular umbilicate punctures moder- 

 ately sparse, lying within rather coarse impressions, smaller near 

 the sides; pit well developed, smooth, the tubercle strong, broadly
