NORTH AMERICAN COLEOPTERA.

Hah. — California. 
Only two female specimens in Dr. Horn’s collection are before me. 
Bears a striking resemblance to Eprinechm viwiicus, described further 
on, from which, indeed, it cannot be distinguished, except by the 
toothed claws. 
Since writing the above I have received a specimen from Dr. Horn, 
which has entirely the coloration of a typical A. snturalls, the elytra 
being bright rufous with the exception of a triangular basal space ; 
it is easily recognized, however, by the form of the jirothorax and 
the le.ss shining elytra. 
A. corvnlus Lee. — Rather robust, oval, black shining: pubescence rather 
long and coar.se, but sparse and easily removed. Beak moderately slender, punc- 
tured with well-marked median carina ; scrobes curved, somewhat ap])roximate 
beneath and directed against the lower angles of the eyes. Anteniife stout, rufo- 
piceous; scape paler, second joint of fuuicle scarcely longer than the third, 
following joints gradually wider, verticels consisting of stiff, bristle-like hairs. 
Eyes feebly convex and slightly free behind. Head convex, occiput impunc- 
tured, front with a few punctures and a well-marked fovea. Prothorax trans- 
verse, more than one-half wider than long, strongly rounded on the sides and 
gradually narrowed to apex, which is feebly constricted ; base scarcely hisinuate, 
surface coarsely, hut not densely punctured. Elytra about one-fourth wider at 
the base than the prothorax ; humeri rounded ; sides a little widened to behind 
the middle, separately rounded at tip, leaving the pygidium freely exposed ; striae 
deejdy impressed, wide: punctures large, not closely approximate : interspaces 
convex, smooth, with small, remote punctures: scutellum white jmbescent: 
underside remotely punctured, pubescence more dense. Legs .slender, thighs 
feebly clavate, all armed with a small, acute tooth : tibiae almost straight, and at 
the apex, like the tarsi, brownish. Long. 1.5 — 2.2 mm. : .06 — .09 inch. 
Hah. — Pennsylvania, Massachusetts, District of Columbia, Illinois, 
W isconsin, Michigan, Texas, Arizona. 
Easily recognized by its small size, shining black color, coarsely 
punctured prothorax and s])arse pubescence. The pubescence is 
easily rubbed off, giving the insect a still more shining appearance, 
and on sujierficial examination, might give rise to confusion. Speci- 
mens are before me of a brown color, probably due to their being 
immature. 
A. sill>$;iittatiis u. sp. — Elongate-oval, piceous, more slender, but other- 
wise closely allied to Jlavicornis, from which it differs in the following charac- 
ters : Pubescence coarse, dense and white. Beak more slender and shining, 
finely and less closely punctured : median carina more distinct, shining, and ex- 
tending to the frontal puncture. Head not concentrically rugulose, second joint 
of funicle scarcely longer than the third. Prothorax less rounded on the sides, 
which are almost straight behind with the hind angles rectangular: apex not 
constricted, punctures smaller and remote on the disc, crowded on the sides: a
