THE PsELAPHID@ OF NorTH AMERICA. 23 
vated above and below the eye, sides of the vertex straight, 
convergent to the frontal margin; supra-antennal tubercles 
strong, angulate; frontal margin convex in the middle and 
declivous at the tip; in a line with the anterior limits of the 
eyes are two pubescent fovez, mutually two-thirds more dis- 
tant than either from the eye, connected by a parabolic sulcus; 
the included space impunctate; labrum truncate anteriorly. 
Antenne not as long as the head and prothorax together, first 
and second joints stout, ovate, nearly equal; third to seventh 
small, gradually transverse; eighth to tenth gradually increas- 
ing in width, nearly equal in length; eleventh sub-globular, 
annulated near the acute tip. Last joint of the maxillary pal- 
pus thick, one-sided, acute at the tip. Prothorax widest 
across the anterior third where the width equals that of the 
head, as wide as long, evenly arcuate at the sides; posteriorly 
the sides are nearly straight, forming a slightly obtuse angle 
with the base; disk polished, impunctate, convex, with an 
abbreviated, linear sulcus just before the middle and a trans- 
verse, slightly angulated groove one-fourth from the base, 
connecting the pubescent lateral fovez; the space behind the 
transverse sulcus is rough, with a median carina. F/lytra, 
across the prominent shoulders, as wide as the prothorax, 
sides divergent, moderately arcuate, disk feebly convex, indefi- 
nitely punctulate, wider than long, and one-fourth longer than 
the pronotum; base bifoveate, the sutural lines parallel, the 
discal impression conspicuous, more than one-third as long as 
the suture. Addomen short, broad, border retuse, segments 
sub-equal, the first and second with two short, divergent 
carine at the base. Legs long, thighs clavate, tibiz dilated 
toward the tip. 9, form more slender, longer than the male, 
eyes rudimentary, consisting of three or in some cases two 
ocelli; the elytra are comparatively longer, the sides more 
arcuate, the abdomen longer, and the tibiz not dilated.
