" Subcosta et radius parallel!, sed ante alae acumen conjunct! ; 

 duo tantum sectores, a radio oriundi, mox in ramos partiti ; multae 

 areolae discoidales, perpendiculares, inter sectorum ramos formatae ; 

 cubitus cum ramis suis aream cubitalem e duabus (vel tribus) cellu- 

 larum seriebus compositam formans; antennae corpore breviores, 

 moniliformes ; interdum ocelli tres." Schneider.
