strong;l\ rounded from tin- front to tin ■ hind angles, which are also less distinct than in 

 punctaftis. 



I, ngth .08-.10 inch. 



Occurs in Cana la and the States bord (ring the Great Lakes. 



In Bull. Mom-. L868, p. 192-3, Motschulskj has indicated two species from the South- 

 ern States unknown to me. 



The following table gives the sp icies nun .1 bj him :

This genus has been removed from the association in which it was placed by Dr. Le- 

 conte, as on renewed examination with fine specimens the penultimate joint of the tarsi is 

 found to resemble thai of the i ther genera of Hetei'otarsini, although less distinctly lobed. 

 It maj readily be Known by the sub-quadrate thorax, not denticulate; epipleurae broad at 

 tip; body glabrous, strongly punctured.

 Length .1 1 inch. 



Specimens are reported from \'< \\ York and South Carolina; it probably occurs every- 

 where in the Atlantic region, though rare. 



TRIBE XXVJ — TRACHYSCELINI. 



Mentum small, supported by a distinct gular peduncle; ligula and maxilla? exposed, 

 interior coxae sub-transverse, middle coxa' with distinct trochantin. Tibia? all more or 

 less dilated and fossorial. Tarsi short, spinous or setose beneath. 



This tribe is here composed of the same genera included in it 1 > \ Lacordaire, their 

 partition in two tribes appearing rather unnecessary and hardlj warranted by the differ- 

 ences exhibited. 



The following table will aid in distinguishing our genera: 



\nti ■una- slender, longer than the head. phaleria. 

 \ntonn;c verj short and clavate. 



Epistoma truncate. trachtscehs. 



Epistoma deeply emarginate. anemia.
