Second joint of fnnicle scarcely longer than the third, scales larger and 
very dense Iiirtiis. 
Eyes less widely separated above, a little more robust; prothorax distinctly 
wider than long oehreopilosus. 
Scales oval ; elytra scarcely wider at the base than the prothorax, mottled.

A. ater Lee. — Oblong oval, black, rather thinly clothed above with whitish 
or ashy-gray piliform scales. Beak long and slender, feebly curved, sparsely 
pubescent near the base, opaque and densely punctured ( 'J, ), or finely and re- 
motely punctured, shining ( 9 h distinctly striate ( 'J, ), or obsoletely so ( 9 )• -'^»- 
tenn» slender, rufous, clava darker; first and second joint of funicle long and 
slender, following joints subturbinate, not wider than long, club densely pubes- 
cent. Eyes feebly convex, not free behind ; front somewhat flattened, obscurely 
impressed transversely, fovea elongate. Piothorax a little wider than long, 
sides broadly rounded and narrowed from base to apex, latter constricted ; base 
scarcely emarginate each side; surface densely, but not coarsely punctured, each 
puncture bearing a scale, which become broader and larger along the median 
line, on the sides and undersurface; scutel densely clothed with white scales. 
Elytra rather suddenly and about one-fourth wider at the base than the protho- 
rax, suboval, a trifle wider behind ; stri® fine, punctures elongate, approximate; 
interspaces almost flat, very slightly roughened ; scales rather piliform, irregular 
in vvidth and entirely concealing the derm, those of the alternate interspaces, 
especially the fourth and sixth, paler; underside of pectus densely covered with 
grayish w’hite scales; abdomen coarsely pubescent. Legs slender, rufo-piceous ; 
femora clavate, armed with a sharp, triangular tooth ; tarsi slender, paler. Long. 
3.6 — 5 mm.; .14 — .20 inch. 
Hub. — California, Oregon. 
Closely allied to squamosus, from which, indeed, it ditiers but little 
structurally, excejit in the form and density of the scales. Comjiarison 
will show at once that it should not be placed among the pubescent 
species. 
.A. $«qiiainosns Lee. — Oval, reddish brown to piceous, densely covered with 
grayish white, or pale yellowish, oval scales; otherwise, like the preceding spe- 
cies, from which it differs, aside from coloration, form and density of scales, as 
follows: Beak reddish brown, more shining, less punctured and scarcely striate. 
Prothorax more distinctly wider than long. Elytra scarcely one-fourth wider 
than the prothorax at its base, humeri more oblique; striae and punctures more 
concealed by the scales. Legs reddish brown. Long. 3.5 4.5 mm.; .14 — .18 inch. 
Hab. -Kansas, Colorado, New Mexico, California, Nebraska. 
Varies considerable in form, coloration and density of the scalv 
vestiture. The alternate elytral intersjiaces are paler in some speci- 
mens, giving them a vittate appearance, more or less marked. 
Two variations, deserving sjiecial mention, occur: 
Var a. — Scales uniformly grayish white, less closely adherent to 
the derm. Each elytral interspace with an irregular row of suberect, 
setae-like hair.
