 from an) of the neighboring tribes. It appears more closely allied to the Tenebrionini 

 than to the tribes immediatelj preceding or following. I'he tribe i- a small one. and com- 

 posed in our fauna of but three genera, easil) known by the very coarse punctures with 

 which the) are ornamented, and may be distinguished a- follows: 



Antenna? very gradually thicker ; epipleurae entire but narrower at tip ;
