ish. Abdomen shining, with extremely minute punctures, these prac- 

 tically absent on segments beyond middle. Hind margins of segments 

 2-4 with white hair bands, broadly interrupted in middle on 2 and 3. 

 Hair at apex light reddish. Second segment in middle depressed 

 more than one-third; but much less than half.

 truncate) and lower margin of clypeus entirely dark red. Clypeus 

 shining, with strong rather dense punctures; no smooth median line. 

 Facial foveae seen from above yellowish white, occupying two-thirds 

 distance between eye and antenna; below they end at about level of 

 top of clypeus. Front punctured; flagellum dark reddish; third 

 antennal joint hardly as long as next two combined. Mesothorax 

 and scutellum with very strong rather close punctures. Area of 

 metathorax with strong, rather regular, long wrinkles, and bounded

 Facial foveae seen from above grayish- white, occupying at least two- 

 thirds distance between eye and antenna, and almost reaching lateral 

 ocelli; beneath they taper to an obtuse point below level of top of 

 clypeus, little separated from eye. Flagellum beneath reddish brown, 

 the color rather bright near the apex. Third antennal joint shorter 

 than. the next two combined. Middle of front shining and punctured.
