lowish, the funicle black ; legs, including coxse, flavo-testaceous. Wings hyaline, 

 with a curved fuscous streak at basal third, a large fuscous spot beyond this, includ- 

 ing the disk, connected with the basal nervure and extending to the hind margin ; 

 there is a large hyaline spot beneath the marginal vein and the apex of the stigmal 

 vein ; another triangular hyaline spot at the hind margin, while the apex of the 

 wing is also hyaline. The head and thorax are opaquely punctate, without striae ; 

 the abdomen is conic-ovate, smooth and polished and terminates in a black, sub- 

 compressed stylus. The antennae are subclavate, not long, the flagellum being only 

 about twice the length of the scape, the last three joints of the funicle a little wider 

 than long.

 and then by another narrow transverse fuscous band ; the apex of the wing is hya-
