THE PsELAPHID@ OF NorRTH AMERICA. 27 
eleventh narrower than the tenth, ovate-acuminate. Prothorax 
slightly longer than wide, widest before the middle, median 
basal fovea small, no median sulcus nor crests; lateral sulcus 
shallow, feeble; the basal tubercles are minute, and behind 
them each side is a punctiform fovea. /ytra convex, im- 
punctured, the suture as long as the width behind the middle; 
across the low unarmed shoulders, as wide as the head. Ad- 
domen with the basal lateral impression broader than the 
middle one, carinz conspicuous, rather long. Legs long, 4 
intermediate tibiz spurred, posterior feebly arcuate, also 
spurred. @ with the front gradually declivous not separated 
from the simple convex clypeus, the tenth antennal joint not 
much longer than the ninth. 
Varies in color being sometimes more reddish or not fully 
colored. 
Habitat. Virginia, Ohio, Kentucky. 
B. FovEIcoRNIS, Casey. Form, color and size as in 2B. 
spretus, differing in the clypeus having a very minute tubercle 
near the narrow sulcus below the frontal margin, which mar- 
gin is again like sfretus. Antenne of the same form but 
with the tenth joint more flattened beneath and the fovea 
larger; the prothorax has a faint very short median sulcus, 
the discal caring hardly discernible, the lateral sulcus appear- 
ing as a very fine line, outside of which the surface slopes to 
the margin. 
My material consists of six specimens of B. spretus and 
one of B. foveicornis from Cincinnati, Ohio, which I can 
hardly separate, as the spretus vary in the direction of Casey’s 
foveicornis, the description of which answers exactly to my 
specimen. ; 
B. puncTiFrons, Casey. Not known to us, but the descrip- 
tion indicates the same relation to spretws, which varies in the 
form of the tenth antennal joint, being in some smaller and 
irregularly formed and with the fovea obliterated.
