 lete above ; narrow fascia on posterior border of pronotum ; tubercle

 posterior surface to end in two points; posterior lateral angles of 

 propodeum; broad vertical anterior stripe on side of propodeum; 

 two spots on metapleura ; anterior border of mesopleura extended 

 backward and then at a right angle upward in a narrow line to base 

 of wing; also rounded posterior spot near base of wings and narrow 

 line above base of middle leg on mesopleura; broad anterior fasciae 

 on tergites 1-6; that on first tergite with irregular borders and 

 narrowed at middorsal line; that on second irregular on posterior 

 border and inclosing a pair of long, narrow, elliptical discal spots;
