The female was reared September 14, 1907, possibly from a gall

 length three times its diameter and apically with a short, stout, 

 knoblike appendage. Palpi ; the first segment short, stout, irreg- 

 ular, the second subrectangular, with a length about three times 

 its diameter, slightly expanded distally, the third as long as the 

 second, slender, tapering at both extremities. Face creamy white, 

 eyes large, black, with fine, white points. Mesonotum dark fuscous, 

 the submedian lines narrowly whitish. Scutellum yellowish, clothed
