Hah. — Abuna, on the Rio Madeira, Brazil {Mann & Baker). 

 A magnificent species, but superficially, when seen from behind, 

 looking exactly like the common E. mussitans (Fabr.). It may 

 also be compared with E. swperha (Hoffm.), to the vicinity of w^hich 

 it runs in Ducke's table. E. manni will be especially known by 

 its mussitans-\\ke appearance, bicolored mesothorax, total absence 

 of a median keel or clypeus, small size of the prominences above 

 the spurs of hind tibiae, and first abdominal segment colored like 

 the rest. The coloration resembles that of E. fallax Smith, but 

 that species has a central keel on the clypeus.
