Smicronyx pacificus, new species 
Fiaures 148, 153 
Descrietion: Rostrum black, rather stout in both sexes, surface 
shining before antennal insertions; rough, coarsely alutaceous behind 
the antennal insertions, four thin dorsal carinae present, but not 
reaching the apex or the base; punctures fine, distinct between the 
carinae, but coarse, less distinct toward the base; scales grayish 
white, thinly distributed over rough dull area toward base. Head 
black, coarsely alutaceous. Antennae piceous except for club, which 
is pale rufous, scales narrow, grayish white. Prothorax black, 
broadly rounded at the sides, narrowed and slightly constricted to- 
ward apex; punctures of disk deep, closely spaced but never confluent, 
usually subcircular in shape; scales rather small, grayish white, and 
thinly distributed. 
Elytra black to piceous in fully colored specimens (many specimens 
seen have more reddish elytra, but apparently are teneral specimens) ; 
intervals thinly covered with small, ovate, grayish white scales, in 
addition to the usual single row of recumbent setiform scales on each 
interval. Underside of thorax and abdomen black, closely covered 
with white, broadly ovate scales. Femora ferrugino-piceous (black 
at bases), thinly covered with elongate whitish scales. Tibiae stout, 
same color as femora, covered with rows of linear, grayish white scales. 
Tarsi rufopiceous, first three segments broad, densely covered with 
elliptical whitish scales; fourth segment projecting beyond the third 
by approximately the length of the latter, claws connate for slightly 
more than half their length, nearly parallel. Male and female 
genitalia typical of the cinereus group (see figs. 50-52), but median 
lobe of male genitalia not as distinctly broadened toward the apex 
as in S. cinereus (fig. 50).
