 mm. ), mesepimeron chiefly pale brown. 

 Mesepimeron without a black spot on the lowest 

 fourth but with a pale brownish stripe, having 

 some bronzy-green reflection, extending from 

 the lower end of the humeral suture almost 

 to the upper margin of the sclerite... gerhardi. 

 Mesepimeron with a black spot on its lowest 

 fourth as wide as the pale antehumeral stripe, 

 remainder of sclerite pale brown. 



gerhardi nigrior. 

 Smaller species (abd. 23.5, hind wing 16.5 mm.) ;

dijjti His. 

 Inferior appendages with lower branch not 

 acutely pointed, projecting but little be-
