 Broadly oval, subdepressed. Pale chestnut 

 brown, shining. Thorax with a groove on each 

 side separating the disli from the lobe, the lat- 

 ter divided by a shallow transverse groove 

 slightly Ivehind the middle. Elytra with sub- 

 humeral and first dorsal entire; second dorsal 

 three-fourths, third two-thirds, the length of ely-

^farion and Lawrence counties; rare. 

 Apri] 28-Aray 11. Occurs in nests of large ^'«-^^*- x i^- (After wheeler.)

In this and the next two genera, the antennal cavities, instead 

 of being beneath the front angles of the thorax are beneath the 

 middle of its sides, and the lobe of the prostemum does not form a 

 floor for them as in the preceding genera of the subfamily. Den- 

 drophilus is represented in the eastern United States and Indiana 

 by the single species :
