Head very regularly obovate, a little broader behind than in front, 

 nearly half as long again ;is broad, its posterior border well rounded. Eyes 

 r.Tther small, situated in the middle lateral! v, projecting but little. Anten- 

 na' srarrrlv if any longer than the head, rather stout, enlarging away from 

 the base, composed apparently of less than fifteen joints. Pronotum as 

 broad as the head and twice as broad as long, semicircular, the front border 

 scarcely concave, the front margins slightly rounded. Mesonotum and 

 metanotmn as broad as pronotmn, quadrate, equal, about half as broad 

 again as long. Abdomen somewhat longer than the rest of the body and 

 slightly broader than the thorax, with gently rounded sides and well- 

 rounded tip : no abdominal appendages are discoverable on any of the 

 specimens. Legs poorly preserved on all specimens ; apparently they are 

 of medium length. 



\Vings rather more than four times as long as broad, the middle of the 

 front pair not reaching the tip of the abdomen, very uniform and regular, 

 of nearly equal breadth throughout the middle two-thirds, the costal mar- 

 gin straight until just before the tip. Scapular vein parallel to the margin, 

 the subcostal area infumated ; veins below the scapular not determinable. 

 The basal scale appears to be small, broad, triangular, its costal border 

 swollen.
