length from the base, the carinæ distinct, entire; antennæ blackish, paler basally, rather short, rapidly and somewhat strongly incrassate, the outer joints distinctly transverse, almost parallel-sided, the last as long as the two preceding, the second and third much elongated, equal; prothorax rather large and transverse, parallel, the sides only feebly arcuate, the apical and basal angles evident but blunt, evidently though not very greatly wider than the head and correspondingly slightly narrower than the elytra, the basal impression rather larger, transversely oval; elytra relatively moderate in size, transverse, the suture slightly longer than the prothorax; abdomen nearly as wide as the elytra, parallel, with slightly arcuate sides, extremely finely and closely but feebly and transversely strigulate, the fifth tergite shorter than the fourth, the sixth (♀) broadly, feebly arcuate apically; mesosternal process extending nearly to apical fourth of the coxæ, gradually narrowing to the acutely rounded but appreciably broad and not at all aciculate apex, which is rather distant from the short and broadly obtuse metasternum; hind tarsi rather long, the basal joint much shorter than the second, two to four gradually and slightly decreasing. Length 3.0 mm.; width 0.8 mm. Oregon (Lane Co.). |
The large size, oblong, subparallel form, antennal and sternal characters are distinctive.
| Atheta nupera n. sp.—Nearly parallel, but slightly convex, slightly shining, black, the elytra castaneous, the legs pale; punctures very fine, rather close, asperulate; vestiture only moderate in length but rather coarse; head moderate, the eyes convex, at nearly their own length from the base, the carinæ extremely fine, feeble and far from entire; antennæ pale brown throughout, well developed, gradually and moderately incrassate, the outer joints slightly wider than long, the last not as long as the two preceding, the second and third moderately elongate, the former the longer; prothorax moderately transverse, distinctly wider than the head and slightly narrower than the elytra, widest at apical third, the sides rounded, straighter basally; surface not definitely impressed; elytra parallel, rather transverse, the suture distinctly longer than the prothorax; abdomen narrower than the elytra, parallel, with the sides straight, shining, the fifth tergite slightly longer than the fourth, the sixth (♀) very broadly and feebly arcuate at apex; mesosternal process extending beyond the middle of the coxæ, drawn out and transversely arcuate metasternum; hind tarsi short. Length 2.65 mm.; width 0.62 mm. New York (Willets Point, Long Island). |
This species is not a perfectly typical Atheta, but to isolate it by subgeneric name would not be advisable at present.
| Atheta reticula n. sp.—Stout, moderately convex, only slightly shining, finely, the abdomen more coarsely, micro-reticulate, finely, moderately closely and asperulately punctate, the punctures of the abdomen fine and sparse but also asperulate; color dark rufo-piceous, the abdomen more blackish, the elytra but slightly paler, the legs piceous; vestiture rather coarse but not long; head moderate, the eyes convex, prominent, setose as |
