Abdomen with the pygidium exposed, rufescent. 



Legs and anteniue rufescent. 



Differs from others in its minute sculptm'e, and pale vitta on the elytra. 



Habitat, Central America. Found in Mexico. 



In the collection of M. des Gozis I found a single example of this species, 

 labelled " Sericoderas tne.vieanus," but, as it was deeply embedded in shellac, I am 

 not able to say whether it belongs to this genus or to Arthrolips. In colour it 

 closely resembles Arthrolips simoni, Reitter, but in shape appears more like a Sacium.
