WILLIAM G. DIETZ, AI. I). 
From aJbopUomu it differs by its stout form, the elytra less coarsely 
striato-]ninctate ; the femora are more slender, the tooth smaller, and 
the tihiie are not curved near the base. 
A. iiigriniis Say.— Subovate, rol)nst, pitchy-black, thinly clothed with 
tine, whitish pubescence. Beak not very slender, oi)aqne, coarsely punctured 
with the median elevated line distinct, shining, and striate each side from the 
base to about the middle ; scrohes slightly curved inferiorly and rather .su])erficial. 
.Antennte inserted about the middle, slender, piceous : first joint of funicle ro- 
bust, second elongate, slender; following joints gradually wider. Eyes feebly 
convex and scarcely free behind. Head short, spherical, with a few, rather 
large, remote punctures, front deeply foveate. Prothorax wider than long, sides 
broadly rounded from the base, moderately narrowed anteriorly and scarcely 
constricted at the apex ; equally, demsely and coarsely punctured. Elytra oval, 
one-third wider at the base than the jirothorax and about one-half longer than 
wide, finely striato-punctate, punctures not approximate: interspaces flat, re- 
motely punctulate; scutellum densely clothed with white pubescence; under 
surface a little more coarsely and densely pubescent; side pieces of thorax and 
abdomen with a few remote punctures. Legs slender, femora feebly clavate, 
armed with a small, acute tooth; tibise rather slender, nearly straight: tarsi long 
and moderately slender, fringed with white hair. Long. 3 mm.; .12 inch. 
Hub. — District of Columbia, Nortli Carolina, Louisiana, Virginia. 
Not unlike ftavicornis, from which it differs in the abdominal for- 
mation, more coarsely punctured thorax and jiitchy-black antennte. 
Might also be confounded with morulus, but is more robust and le.ss 
convex, and the elytra more shining. Its resemblance to ebenimis 
has been noted under that species. 
-A. all>01>ilo»4ilS n. sp.— Oblong-elliptic ; black, somewhat shining, not 
densely clothed with long, white pubescence. Beak longer and more slender 
than in nigrinus ; smooth, shining, sparsely and finely i)unctured ; snbsti inte from 
the base to about the middle, median elevated line well marked, shining ; .scrohes 
straight. Anteniife slender, inserted about two-fifths { 'J, ) or one-half ( 9 ) from 
the apex ; rufo-testaceous, first joint of funicle long and less stout, second joint 
a little more slender, elongate: following joints scarcely wider than long. Eyes 
almost flat, not at all free behind. Head subconical, somewhat shining, and 
rather coarsely j)unctured, frontal fovea deep. Prothorax a little wider than 
long, rather strongly narrowed in front and feebly constricted at the apex, sides 
broadly rounded; surface closely, but not very coarsely punctured : base nearly 
straiglit each side. Elytra oblong, shining, but little wider at the base than the 
prothorax, feebly rounded on the sides and gradually narrowed to the tij). coarsely 
striato-punctate, punctures rounded, approximate: interspaces moderately con- 
vex, punctured; under surface rather coarsely, but not very closely i)uiictnred. 
more densely and coarsely pubescent. Legs long and slender, femora (davate, 
armed with a triangular tooth, which is larger and very in-oininent on fhe ante- 
rior pair; tibite slender, anterior strongly curved near the base and bisinnate 
iTiternally; tarsi long and slender. Long. 2.8 — 3.3 mm.; .11 — .13 inch.
