NORTH AMERICAN COLKOPTERA.

Hired and iMihescent; a median and lateral elevated line, not very marked. An- 
tennse inserted remotely from tlie apex, rather stout, scape and first joint of 
fnnicle bright rufous, remainder fuscous; second joint of funicle longer than 
the third, following joints rounded. Eyes feebly convex, entirely lateral and 
widely separated above. Head densely punctured and pubescent ; frontal fovea 
narrow, elongate. Prothorax scarcely wider than long, gradually narrowed from 
base to apex; base almost straight each side; sides very feebly rounded, apex 
slightly constricted and transversely impressed behind the anterior margin ; sur- 
face densely, deeply, but rather finely punctured, and rather densely clothed 
with scales, which are larger than those of the elytra. Elytra rather suddenly 
and about one-third wider at base than the prothorax, elongate, sides almost 
parallel, gradually narrowed posteriorly, coarsely striato-punctate, punctures 
round, approximate; interspaces convex. Legs rufo-piceous, moderately slender, 
thighs not strongly clavate, anterior armed with a very small triangular tooth, 
middle and po.sterior mutic; tarsi slender, rufous; ventral segments 3-5 of male 
equal and separately, but little shorter than first or second ; third and fourth 
segment of female shorter, fifth longer, rounded. Long 3 — 3.5 mm.; .12 — .14 
inch. 
Hah . — Oregon (H. Ulke), Colorado (Dr. Horn). 
Two males and one female are before me. Closely allied to hirtus, 
but is less densely scaly above and the .second joint of fnnicle is dis- 
tinctly longer than the third. Not unlike H. effetns in form and 
coloration, but is a little more elongate, and the vestiture consits of 
true scales, while in the former it consists of siiberect, scale-like pu- 
bescence. 
A. liirtiis Lee.— Of the same form and sculpture as the preceding, but a 
little smaller and densely covered with grayish or ochreous scales, which com- 
pletely conceal the color of the derm, which varies from rufo-ferruginous to 
pitchy-black. Antemife and legs rufo-ferruginous; the beak is more slender and 
scarcely striate or punctured ; the second joint of funicle is scarcely longer than 
the third ; three thoracic; vittse and along the suture paler, each elytral inter- 
space with a row, more or less irregular, of short, suherect, piliform scales. Legs 
and tarsi as in mnrinus. Long. 2.8 — 3 mm.; .11 — .12 inch. 
Hob. — California, Arizona, Utah. 
The scales vary in form from broadly oval to piliform. The sub- 
erect, scale-like hairs of the interspaces are almost olxsolete in some 
specimens. Resembles also the next species. 
A. oclireopilosus n. sp. Pi. vi, fig. 17.— Oval, less elongate than the 
preceding, rufo-piceous, upper and under surface densely clothed with ochreous, 
lanceolate, suberect scales. Beak a little shorter and less slender than in hirtus, 
curved and a little widened at the apex; shining, punctured and thinly pubes- 
cent, median elevated line not distinct. Antennse ferruginous, moderately slen- 
der; second joint of funicle longer than the third. Eyes somewhat convex, less 
widely separated above than the base of the beak. Head short, punctured, and 
densely pubescent; frontal fovea elongate. Prothorax about one-half wider than
