6. Outer apical angle of front tibiae prolonged; form robust; length 



14 mm. LXII. NOTHOPUS. 



6&. Outer apical angle of tibiae not prolonged ; form less robust ; length 



less than 11 mm. 



c. Mentum toothed ; hind angles of thorax sharply rectangular ; 

 length 8-10 rum. LXIII. CRATACANTHUS. 



cc. Men turn not toothed ; length less than 8.5 mm. 



d. First joint of hind tarsi slightly longer than second; outer edge 

 of middle tibia? rather flat and with a double row of spiuules 

 closely placed ; elytra with one dorsal puncture. 



LXIV. AGONODEKUS. 



dd. First joint of hind tarsi nearly as long as the next three; middle

LXV. DISCODEKVS. 



LXI. GEOPINT-S Lee. 1848. (Gr.. "earth + dirt.") 



Represented in the United States by one medium-sized robust 

 species which burrows deeply in damp, sandy localities. The sur- 

 face is smooth and glabrous, thus favoring its subterranean life. It 

 may often be taken by suddenly turning over an old log partly 

 buried in sand.

Represented in the United States by a single rather large, ro-

 northern Indiana.
