with a pale brown blotch on either side of the median sclerite, the lateral sclerites 

 unmarked. Pleura orange-yellow. Hal teres brown, the base of the stem 

 yellowish. Legs with the coxa orange, the outer face of the fore coxae slightly 

 infuscated; trochanters orange; remainder of the legs broken. Wings with a 

 grayish tinge, cell C faintly yellowish, cell Sc more strongly so; stigma brown; 

 a brown seam along the basal deflection of Cuu veins dark brown. Venation:' 

 Rs almost straight, much longer than R^+z and not in alignment with it; petiole 

 of cell .1/1 a little shorter than m; fusion of M^ and Cui punctiform. 



Abdomen with the basal tergites narrowly blackish laterally, less dis- 

 tinctly darkened medially; fourth to sixth tergites brownish yellow, the lateral 

 margins broadly black except at the base, the median area with an elongate 

 black triangle with the point directed backwards; seventh and eighth tergites 

 black; h>'popygium reddish yellow; sternites uniformly yellowish, the seventh 

 sternite with the posterior lateral angles blackened; eighth sternite medially at 

 the base and laterally at the outer angles, blackened. Male hypopygium with 

 the sclerites fused into a continuous ring as in the subgenus; median lobe of the 

 tergite very broad, depressed, the caudal margin gently concave and set with 

 numerous small blackened spicules; the sides of this lobe are provided with long 

 yellowish bristles that are longest at the posterior lateral angles of the tergite. 

 Pleural suture well indicated beneath; pleural appendages united into a single 

 highh-complicated structure; what seems to correspond to the outer pleural 

 appendage is a bifid lobe with the arms densely hairy; the inner appendage is 

 produced into an outer chitinized spine, and intermediate flattened blade and 

 an inner powerful compressed arm that juts toward the ninth tergite and corres- 

 ponds to this inner blade in less specialized species; the inner face of this blade 

 is covered with numerous, short bristles; the cephalic apex is rounded. Ninth 

 sternite with only a shallow median notch, the remainder of the median area 

 being filled with a pale membrane; proximo-caudal angles with a coarse pencil 

 of reddish bristles that are decussate across the median line. Eighth sternite 

 unarmed.
