cal spot and apex of dense, whitish pnhescence; nnderside densely punctured 
and coarsely pnhescent. Legs slender, ferruginous; thighs feebly clavate. infns- 
cate about the middle, all armed with a sharp tooth ; tihije slender, nearly 
straight, all artned with a small hook at the apex ; tarsi moderate, first and second 
joints slightly elongate, equal; third feebly hilobed, lobes small; claws di\’er- 
gent, armed with a small, acute tooth. Long. 2.5 — 3.2 mm.; .10 — .13 inch.

The imbescence is easily rubbed off. 'fwo specimens taken early 
in the Spring by Dr. Hamilton, and kindly sent me for examination, 
are entirely deprived of pubescence, probaldy due to hibernation, 
the occurrence of which must be rare among the members of the 
present tribe. 
PSEmAlVTHOXOitlllS gen. nov. 
Beak rather stout, moderately long and curved; scrobes oblique, 
directed beneath, rarely {craUegl, valiclus) against the lower extremity 
of the eye. Anteniue not very slender, inserted two-fifths ( S ) or 
one-half ( 9 ) from the apex ; scape incrassate at its distal extremity ; 
funicle 6-, rarely (rellctus) 5-jointed ; fourth joint (third, relictvs) 
shorter and smaller than eithei' of the preceding or following joints 
(except briinneus, parvulus) ; club loosely articulate, pubescent. 
Eyes variable. Head subspherical, punctured. Prothorax wider 
than long, bisinuate at base, narrowed in front and constricted at the 
apex. Elytra transversely impressed behind the base ; strise and 
punctures coarse and deep; scutellum densely |nibescent; proster- 
num short in front of the coxie; mesosternum narrowed behind; 
metasternum moderately long; ventral segments nearly equal, fifth 
a little longer than the fourth in the female ; pygidium exposed, 
middle coxie narrowly, posterior not very witlely sejiarated. Legs 
slender, femora feebly clavate, all toothed ; tibiie slender, anterior 
and middle unguiculate, posterior mucronate at apex ; tarsi slender, 
claws armed with a long and slender tooth. 
The species are all of a rufo-testaceous or ferruginous color and 
pubescent, both on the upper and under surface, without any scales. 
In all, except /ocefa, 9, the first and .second, third and fourth, fifth and 
sixth elytral striie become confluent at the base, the interspaces thus 
enclosed do not reach the basal margin, the third interspace becomes 
wider and more prominent at the anterior extremity (except /cicebw). 
The species reseiidile each other very closely, are difficult to dis- 
tinguish, and are, with the exception of cratcegi and incipiens, rep- 
resented by a single, or but a few specimens. 
They are to be distinguished as follows :
