This genus re{|uires amplification in its generic charaetei*s 

 so tar as the ueuration ot the membrane is concerned. 

 Dallas, in his " Table of Genera," distinguished liathriis by 

 having " membrane with three nervures," but in fully de- 

 scribing the genus subsi ([uently he wrote " membrane with an 

 oblong basal cell and four longituilinal nervures, of whiidi 

 the two outer are furcate." In the speei»»i I now describe, 

 none of the nervures arc furcate.
