Abdominal tergites yellow with a very broad black median strii)e tiiat 

 broadens out behind, on segments five to nine including the entire segments; 

 caudal margins of segments two to four indistinctly pale; sternites yellow, 

 on the fifth and succeeding segments passing into blackish; the boat-shaped 

 appendage on the eighth sternite yellow. The abdominal segments before 

 the hypopygium are very short and crowded, tergites six to eight being very 

 narrow; male hypopygium moderately incrassated; ninth tergite ending 

 in two very broad, flattened lobes, their caudal margins subtruncate, the 

 lobes separated from one another by a deep narrow sjilit; eighth sternite 

 produced into a conspicuous, arcuate, boat-shaped appendage which is con- 

 spicuously fringed with yellow hairs.

 infuscated on the vertex. 



Pronotum gray with three darker markings. Mesonotal praescutum gray 

 with four brown stripes, the intermediate pair not attaining the suture and

 of Ml and 2nd M-i, except a pale spot in the base of the latter; a broad band 

 along the cord from the dark brown stigma; a broad, somewhat paler band 

 across the middle of cells R, M, Cu and the end of 1st A, 2nd Anal cell and 

 the base of the 1st Anal cell similarly darkened; the broad hyaline cross- 

 band beyond the stigma is complete, including practically all of cell 1st M2 

 and extending clear across the wing; veins dark brown, Sc and R yellow.
