$ . Very near G. si/vcrlocki described above, but differs 

 in the clypeus, \vl;ieh is subtruneate and very shal lowly 

 emarjijinate at the apex ; in the slenderer form; the median 

 segment is three times as wide at the base as at the apex, 

 only twice as wide in sUverlocki, the first abscissa of the 

 radius is three times as long as the second, and the eyes are 

 a little more widely se[)arated on the vertex, though much 

 nearer in this character to sVvei'locki than to lutnellatas and 

 capensis. Tlie median segment shows indistinct transverse 

 striae near the middle.
