finely, closely, simply and very clearly punctate; abdomen parallel or very nearly, slightly narrower than the elytra; basal joint of the hind tarsi similarly long, the mesosternal process very much shorter and triangular, not prolonged and finely aciculate as it is in the preceding. Length 3.3 mm.; width 0.75 mm. California (Sta. Cruz Mts.) |
Very distinct from bicariniceps in the formation of the sterna and abdomen; the infra-lateral carinæ of the head are similarly entire but are finer and not so elevated.
| Atheta (Athetalia) nimia n. sp.—Form parallel, convex, large in size, black, the elytra, legs and antennæ basally brownish-rufous, the abdominal tip faintly paler; lustre moderately shining, the integuments rather strongly micro-reticulate, the abdomen with excessively fine and close transverse strigulation; head well developed, the eyes not very convex, at about their own length from the base; antennæ not quite so long, moderately stout, not gradually incrassate but parallel except basally, the joints slightly wider than long, the eleventh not quite so long as the two preceding; prothorax distinctly wider than the head and correspondingly narrower than the elytra, convex, transverse, parallel, unusually strongly and evenly rounded at the sides, finely, not densely punctulate and with two minute approximate and coalescent impressions before the base; elytra large, wider than long, finely punctulate, very much longer as well as wider than the prothorax; abdomen parallel, much narrower than the elytra, minutely, sparsely punctulate, the fifth tergite a little longer than the fourth, the sixth in the type broadly rounded, becoming gradually distinctly sinuate at the middle of the apex; mesosternal process very long, extending three-fourths of the coxal length, becoming very finely drawn out and aciculate. Length 4.2 mm.; width 1.0 mm. British Columbia (Metlakatla),—Keen. |
This is the largest Athetid known to me from North America and is very distinct from the two preceding. The basal joint of the hind tarsi is similarly elongate.
Megista Rey.
The following species agrees very well with subplana in all its structural characters, including nearly obsolete infra-lateral carinæ of the head, short basal joint of the hind tarsi and approximate middle coxæ, with very short metasternal projection, but the mesosternal process is noticeably longer. Granulata Mann., (Elytrusa Csy.) is closely allied but larger and with a notably larger head and still longer and stouter antennæ; I do not think that granulata can be the same as the European graminicola Grav.
| Atheta (Megista) nomadica n. sp.—Moderately stout, parallel, deep black, moderately convex, rather strongly shining, the elytra not distinctly picescent, the antennæ nearly black, the legs piceous-brown; head small, orbicular, |
