I am not at all sure of the two foregoing identifica- 

 tions. They may be only one species. The humeri 

 all show signs of orange, but the legs are brightly 

 yellow with sharply defined black tipped hind 

 femora in No. 3, while in No. 5 they are all 

 brown. 



6 (5). Frons mostly black. (2369. cothurnata, Pz.)
