Specimens examined. — I have seen only the three types. 



Renfiarks. — This species differs from hvscki by its fine pronotal 

 punctures, the lack of emargination of the sides basally, the long 

 elytra, and its greater size. It differs from turquinus in the shape 

 of tlie pronotum. 



I have received no record of its habits.
