Psyche 
[September 
Head densely rather coarsely punctate, antennae long, 
strongly serrate, the 8th joint attaining the tip of the hind angle 
of the thorax; joints 2-3 small, subequal, together two-thirds as 
long as the 4th. 
Prothorax slightly wider at middle than its median length, 
sides straight and moderately diverging to the hind angles which 
are more strongly divergent and carinate; disk convex, median 
line feebly impressed, punctuation somewhat finer than on the 
head, rather sparse at middle, the punctures there separated by 
from one to two times their diameters, closer toward the margins. 
The sides are evidently though feebly margined. 
Elytra nearly parallel sided, three times as long as wide, very 
feebly obsoletely striate, intervals densely scabrous punctate. 
Last ventral segment one-half longer than the preceding, 
feebly sinuate each side of the apex which is narrowly sub- 
truncate. Middle and hind tarsi distinctly longer than the tibiae. 
Length 16 mm.; width 3.9 mm. 
California (Camp Nelson, Tulare Co., Aug. 28, 1913); a 
single male example. 
By Horn’s table this species is to be associated with optatus, 
from which it differs by the almost obsolete elytral striae and 
the densely scabrous punctate and dull interspaces. In optatus 
the 3rd antennal joint though small is plainly longer and wider 
than the 4th; only very slightly so in the present species. 
Aplastus piceicollis n. sp. 
Form slender, head and pronotum piceous, elytra ferru- 
ginous brown, strongly shining throughout, the pubescence 
sparse and very fine. 
Head closely strongly punctate; antennae strongly serrate, 
8th joint reaching tip of hind angle of thorax, 2nd joint very 
small, transverse, 3rd subtriangular, very nearly twice as long as 
the 2nd and distinctly longer than wide, the two together about 
two-thirds the length of the 4th joint. 
Prothorax about one-seventh longer on the median line 
than the median width; sides straight, barely visibly diverging 
to the flaring hind angles which are strongly produced and finely
