He says the "adult female is almost entirely yellow, with a 

 darker tinge on the thorax, dorsally, and at the extremities of the 

 antennae and feet; the eyes are red, semiglobular, faceted, placed 

 on a short tubercular base. The head is broader than long, 

 depressed in front and produced beneath in two moderately long 

 sub-conical processes : the rostrum is cylindro-conical. The 

 antennae have 10 joints, all elongated, subequal and ringed, except 

 first two, which are short and smooth." The genitalia are 

 remarkable, and the wings more elongated and pointed than in 

 most species.
