 of the subspecies atratus) rather mat, the frons and upper part of 

 pronotum with sparse, long, scattered setae coming from punctures 

 separated from one another by an average of about 4.0 then- diameter; 

 mesoscutum with dense punctures over most of its surface, or the 

 punctures more or less restricted to its hind 0.25; mesopleuron, meta- 

 pleuron, and propodeum subpolished, with scattered, very sparse 

 punctures; second tergite subpolished, with small weak punctures 

 that are separated from one another by about 2.5 their diameter.
