 microscopical : face and front minutely tessellate, sides of 

 front as densely punctured as is possible ; sides of meso- 

 thorax (also minutely tessellate) with punctures about as far 

 apart as the diameter of one ; middle o£ mesothorax with

 minute piliferous punctures only ; area ot metathorax with 

 irregular basal pliciie ; abdomen with extremely fine piliferous 

 punctures, sparse but not absent on disc of first segment ; 

 third segment with much beautifully plumose hair ; hind 

 spur with four long teeth. The type carries much yellow

 States. The insect is nearest to D. occidentalis, from which 

 it is known by the brassy or greenish-tinted abdomen and 

 somewhat dtisky wings.
