'J'his genus resembles Erodius and Asida in the last joint of tlio 

 antenna;, but it differs from them both in the labrum, labium, and 

 mentum. With Erodius it has a bifid sternum ; its cljpeus, how- 

 ever, is not bifid, in which it agrees with Asida, but the sternum 

 of the latter genus is entire.
