NORTH AMERICAN COLEOPTKRA.

A very distinct species, differing from the preceding by its longer 
and denser pubescence, the anterior tihire curved near the liase, the 
large anterior femoral tooth, and also its more slender form. 
The fifth ventral segment is twice as long as the fourth ; the j)y- 
gidium remotely punctured, pubescent in the male, glabrous in the 
female. 
Taken in large numbers at Albuquerque, N. Mexico, by F. H. 
Wickham. 
A. .’Kantliociienius n. sj).— Eo))ust. dark piceoiis, with a faint aeneous 
lustre, clothed above with coarse whitish ))uhescence, which becomes denser and 
more scjuamiform on the under surface. Beak long and slender, opaque ( 'J, ) or 
shining ( 9 ), slightly compressed at the base; flattened, and a little wider at the 
apex; scrobes linear, straight and deeii. Antennae slender, testaceous, inserted 
scarcely two-fifths from the apex; first joint of funicle long and slender, joints 
2-4 somewhat elongate, subequal, 3-7 shorter; club loosely articulate, dusky. 
Head broadly conical, smooth, with a few small distant punctures; front sulcate 
between the eyes, the latter moderately convex, not or scarcely free behind. 
Protborax much wider than long, strongly narrowed in front, base bisinuate ; 
sides nearly straight behind, strongly rounded in front and constricted at the 
tip; surface rather densely and coarsely punctured, except anteriorly, where the 
punctures become smaller and more distant; transversely impressed behind 
the anterior margin ; pubescence somewhat condensed along the median line and 
on the sides. Elytra broadly oval, strife deeply impressed, punctures rather 
large and closely approximate; interspaces convex, rugulose and irregularly 
punctured; scutellum densely pubescent; side pieces of thorax and .abdomen 
finely and remotely punctured. Legs slender, thighs clavate, all armed with a 
small, acute tooth ; base of middle and hind thighs, and distal half of all the 
tibife pale testaceous, latter slender, anterior tibife feebly bi.sinuate internally; 
tarsi slender, dusky. Long. 2.5 — 3 mm. ; .10 — .12 inch.

This species has been confounded \v\th fiavicornis, from which it is 
easily di,stinguished, aside from structural difterenees, by the colora- 
tion of the legs. It varies somewhat in sculpture. A specimen in 
mv collection which I refer, with some hesitation, to the present spe- 
cies, has the elytra rather finely punctato-striate. It is closely related 
to the two following species. 
A. H'lieoliiM n. sp. — Closely allied to the preceding, but is smaller and 
much less robust, blackish with feueous lustre ; pube.scence white and fine. Beak 
shorter and a little stouter, not flattened at the apex ; scrobes shorter. Antennae 
rather stout, inserted about one-balf from the apex and entirely testaceous, club 
slightly darker; second and third joint of funicle not elongate, former a trifle 
longer than the latter, following joints transverse. Eyes more strongly convex 
and free behind. Protborax less coareely and less densely i)unctured. Elytral
