NORTH AMERICAN COLEOPTERA. 
195 
Legs slender ; femora clavate, at least the anterior bidentate. Tibise 
feebly bisinnate internally; apical armature strongly developed. 
Tarsi slender, first joint elongate, third feebly bilobed, spongio-pilose 
beneath, fourth joint moderately long. Claws large, broad, slightly 
divergent and deeply bifid, especially the anterior; teeth scarcely 
approximate to each other. The vestiture consists of coarse pubes- 
cence. 
The type of this subgenns is ^4. fulvus Lee., to which I have to 
add two new species from Lower California, very recently received by 
Mr. H. Ulke. The species are at once recognized by the eyes being 
situated at the base of the rostrum ; they are smaller and narrower 
in A. fidvm than in the other species. They are readily distinguished 
as follows ; 
Pubescence forming pattenis on the elytra ; anterior femora alone bidentate. 
tiilvns. 
Uniformly pubescent; all the femora bidentate. 
Black ; head constricted behind the eyes, which appear more prominent. 
peniiisiilaris. 
Ferruginous; head not constricted behind the eyes; front transversely im- 
pressed pervilis. 
.4, f'iilvii!i$ Lee. Plate v, figs. 8, 8a. — Elliptic, ferruginous, thinly clothed 
above with coarse, pale yellowish pubescence. Beak not very slender, quadri- 
sulcate, sulci punctured. Antennae inserted one-third {%) or two-fifths ( 9 ) 
from the apex. Eyes transversely oval, slightly convex. Head finely and re- 
motely punctured, moderately constricted behind the eyes; frontal fovea large 
and deep. Prothorax about one-half wider than long; sides rounded; apex 
feebly constricted ; surface very coarsely and suhconfiuently punctured, each 
puncture bearing a yellowish hair; pubescence condensed along the median line. 
Elytra a trifle wider at the base than the prothorax, sides very feebly rounded, 
gradually narrowed to and slightly separated at the apex; strife fine, feebly im- 
pressed ; punctures moderate, elongate, coarser and more dee])ly impressed at the 
base; interspaces flattened, remotely punctulate, pubescence condensed in lines 
as follows; short post-scutellar line, second and eighth interspace from near the 
base to the apex, apical half of tenth, an anterior oblique and posterior subtrans- 
verse line behind the middle and extending from the eighth interspace, to the 
third, where they coalesce; between these latter lines another exists on the sixth 
interspace. Scutellum densely pubescent. Underside punctured, more densely 
pubescent, especially on the thoracic side pieces. Long. 4.5 — 5 mm. ; .18 — .20 inch. 
Hub. — Kansas, Indian Territory, Texas. 
A readily recognized species. 
A. |>eiiiiistilai*i!« n. sp.— Oblong oval, pitchy black, conspicuously clothed 
with long, coarse, dirty white pubescence, which is scarcely more dense beneath 
than above. Beak slender, curved, strife w'ell impressed, coarsely punctured, 
apical portion more remotely punctured ( % ). Antenufe slender, inserted twm-
