margin narrow, the segments sub-equal, the first two with 
short carine at the base. Legs long, thighs robust, tibiz 
slender; male intermediate thighs lunate, the intermediate 
tibize with an internal tooth. 
Habitat. New York. 
Faronus, Audé. 
Antenne inserted beneath the moderately distant frontal 
tubercles, joints moniliform, gradually slightly larger; palpi 
short, the last joint oval or elongate oval; vertex trifoveate; 
eyes moderately prominent, the facets not very large. Pro- 
thorax commonly wider than long, with two small fovee near 
the center and a transverse excavation limited laterally by a 
carina which separates it from the lateral fovea, posteriorly by 
a roof-shaped transverse carina which divides it from the basal 
line. Elytra usually with nearly straight divergent sides, the 
line of the sides if prolonged touching the sides of the protho- 
rax and the eyes anteriorly, and the first three segments pos- 
teriorly; the disk is depressed, with deeply interrupted or 
strongly foveate lines. Abdomen, basal segment shorter than 
the two succeeding ones, broadly margined, the segments 
quite flexible and somewhat retractile; segments six in num- 
ber. Pubescence usually very coarse and long. Legs slen- 
der, short, tarsi short, the first two joints very short, the last 
with two equal claws. Posterior coxz approximate, slightly 
transverse. Antenne with the third joint smallest. ‘lhe fol- 
lowing table will enable the student to identify his specimens.
