THE PsELAPHIDZ OF NortTH AMERICA. 221 
Abdomen broader than the elytra, convex, polished, impunc- 
tate, the first dorsal segment very large, longer than wide, 
broadly margined, margin convolute at base, hairy, diminishing 
in width posteriorly, basal fovea extending from the suture two- 
fifths of the length of the segment. Two posterior dorsals 
very short. Mesosternum arrow-shaped, anterior coxe cylin- 
drical, contiguous, their trochanters arcuately conical, half as 
long as the femora; intermediate coxz small, rounded, pos- 
terior transverse, femora angulate, the ridges setigerous, 
grooved externally at the distal end for the reception of the 
cylindrical, two-jointed tarsus. 
In the male the end of the middle trochanter has a curved 
claw as long as that member. 
Habitat. Pennsylvania, Georgia, Illinois. Len, Tstone 
A. LEcONTEI, Brend. Honey yellow, pubescence in regu- 
lar rows. Length, 2.5mm. Plate VI., Figs. 1 and 2. 
Head twice as long as broad, broadest along the inter-antennal 
line, base only two-thirds of that width. Frontal margin and 
sides straight as seen from above; vertex with two entire, 
shallow, longitudinal impressions. Last antennal joint slightly 
arcuate, otherwise of the same form as in A. cecus. Protho- 
rax bell-shaped, a little longer than the head, base twice as wide 
as the neck, sides slightly arcuate, disk transversely convex, 
with a transverse sulcus one-fifth from the base, which is inter- 
rupted in the middle by an oval tubercle. Space between 
the sulcus and the base ring shaped, convex, with a flat,. cir- 
cular plane in the middle bearing a center-point. /ytra as 
in A. cecus. Basal abdominal segment wider than the elytra, 
margin arcuate and convolute near the base, thence divergent 
in a nearly straight line to the posterior limit of the segment. 
Disk trapeziform, convex, fovez similar in form to those of 
A. cecus, which it also resembles in the sexual characters. 
Habitat. Mississippi Valley.
