parallel, the sides feebly and subevenly rounded, unimpressed; elytra larger, much shorter than wide though very much longer as well as wider than the prothorax; abdomen narrower than the elytra, parallel; three basal joints of the hind tarsi decreasing moderately in length. Length 1.75 mm.; width 0.4 mm. Rhode Island (Boston Neck). |
Readily distinguishable by the relatively small head and prothorax and wide elytra; the eyes are more developed than usual and the tempora are not in the least inflated.
| Atheta (Micrearota) fecunda n. sp.—Coloration and fine indistinct punctuation as in the preceding, the reticulation small and feeble but more or less evident, that of the abdomen coarser byt feebler and, as usual, irregular; head nearly as long as wide, the eyes moderately convex, at a little more than their own length from the base, the swollen tempora slightly more prominent, the carinæ fine but long and entire or very nearly so; antennæ only moderately short, of the usual structure, stout except basally, the outer joints transverse, the ninth evidently shorter than the tenth, the last pointed at tip and about as long as the two preceding; prothorax rather transverse, much wider than the head and evidently narrower than the elytra, widest near apical third, the sides broadly rounded, straighter basally, unimpressed; elytra moderately short, transverse, the suture not impressed and materially longer than the prothorax; abdomen much narrower than the elytra, parallel, with straight sides; hind tarsi as usual, slender, the first three joints rapidly decreasing. Length 1.6-1.75 mm.; width 0.35 mm. New York (Catskill Mts.). |
DIstinguishable from any other species by the unusual development of the infra-lateral cephalic carinæ, which are frequently virtually entire though sometimes abbreviated, always however, so far as observed, extending well before the middle.
| Atheta (Micrearota) sana n. sp.—Rather stout, only feebly convex, colored as in the preceding species, shining, the fine reticulation feeble, the minute punctures not dense; pubescence rather coarse; head nearly as long as wide, the eyes well developed, at rather less than their own length from the base, the tempora parallel, feebly arcuate, not at all more prominent, the carinæ wholly obsolete; antennæ very stout, rather short, distinctly incrassate, the outer joints mutually similar in form, strongly transverse, the last pointed, stout, rather longer than the two preceding; prothorax unusually transverse, but little narrower than the elytra and much wider than the head, the sides almost evenly and moderately arcuate, unimpressed; elytra moderately transverse, much longer than the prothorax; abdomen distinctly narrower than the elytra, perfectly parallel, with straight sides; first three joints of the hind tarsi rapidly diminishing in length, slender as usual. Length 1.6 mm.; width 0.42 mm. Pennsylvania (Philadelphia). |
Recognizable among the other species by its rather stout form and transverse prothorax.
