gagates, mihi. — Black, shining. Head not elongate ; teeth 

 quite pointed, centre indentation quite triangular, the teeth 

 being slightly reflexed. Head strongly punctured, except on 

 disc, where it is quite smooth ; strongly margined. Thorax

 punctured. Elytra depressed on disc, base bicarinate. Anterior 

 tibiae very strongly toothed, all the teeth being sharply punc- 

 tured and squamose at tips ; the dentations very strongly ser-
