Psyche 
[September 
Cebrio speratus n. sp. 
Moderately elongate, parallel, dark brown and somewhat 
shining above; antennae, legs and body beneath rufo — to fulvo- 
testaceous. Head densely strongly punctate, labrum broadly 
angulate emarginate. Antennae moderately serriform, passing 
the hind angles of the thorax by about four joints, 3rd joint 
slightly more than half as long as the 4th, median joints scarcely 
one-half longer than wide. 
Prothorax at middle about one-fifth wider than the median 
length, sides feebly arcuate to nearly straight, converging slight- 
ly toward the front, lightly sinuate before the hind angles which 
are small and strongly divergent; surface rather finely punctate, 
the punctures distant on the average by their own diameters or 
a little more. 
Elytra nearly parallel sided, four and one-half times as long 
and one-third wider than the thorax; striae rather feebly im- 
pressed, the strial punctures not or with difficulty distinguishable 
from those of the closely punctate intervals. 
Prosternal intercoxal process narrow or sublinear, last 
ventral segment evenly rounded at apex. 
Length 12.5 to 14.5 mm.; width 3.6 to 4.2 mm. 
Described from a series of twelve specimens from Hope, 
Arkansas (June 18 — July, Miss Louis Knobel) and Winnfield, 
Louisiana (June 15, G. R. Pilate). The type is from the first 
named locality; all examples are males. 
This species is allied to both bicolor and antennatus. From 
the former it differs in being generally smaller, with more finely 
and less closely punctured thorax, more feebly impressed elytral 
striae, narrower prosternal process and unemarginate last ventral. 
Concerning a specimen sent to Mr. Schaeffer for comparison 
with his type of antennatus , he writes — “Differs from antennatus 
in being less elongate, the punctuation of the thorax finer and 
less close, the hind angles more strongly divaricate, the antennae 
shorter with the joints less strongly produced apically.”
