genibus, tibiis tarsisque nigris ; elytris crebre punctatis, singu- 

 latim puncto apicali vittisque duabus, una submarginali, plerumque

Head coarsely punctured; apex of jaws and a quadrangu- 

 lar patch between the eyes black: antennse robust, slightly

 hinder row is formed of three patches, the outer two of which 

 are large and irregular, the middle small and oblong.

 duabus, thoracis maculis septem (4 , 3 dispositis), scutello, geni- 

 bus, tibiis, tarsis pleurisque nigris ; elytris postice paullo ampliatis, 

 crebre punctatis, singulis apice plaga transversa subapicali, fasciis-
