Fore wings with the postcostal vein distant from the margin and curved 

 in an opposite sense. Stigmatic vein arising very early, near the proximal 

 cud of the long stigma, so that the stigmatic cell is fully two-fifths the 

 length of the wing. Cubital vein once forked far beyond the base of the 

 stigmatic vein, and at a long distance from its own origin, which is near the 

 middle of the outer half of the space between the first oblique and stigmatic 

 veins, the second oblique vein arising twice as near the first as the cubital 

 vein, but not very near the former, though somewhat nearer than repre- 

 sented on the plate, diverging from it at a slight angle, so that the first dis- 

 coidal cell between them is nearly or quite four times as broad on the hind 

 margin as at the base. Abdomen long oval, no broader than the thorax, 

 a 1 tout twice as long as broad, and a little pointed apically. 



A single species is known.

The greater portion of a body with the wings of one side represents 

 this small species. The body is mottled and barred with dark brown. The 

 wing is represented <>n the plate with altogether too full a hind margin, for 

 the wing is really more than three times as long as broad. The middle of 

 tin; l>asi; of the first discoidal cell is midway between the base of the wing 

 and the >tigmatic vein. The first obliquo vein is straight, and parts from 

 the postcostal at an angle of lit'tv derives: the second gently sinuate, at an
