 broad across the middle, rather narrow towards the tips, hardly con- 

 vex in front, almost rectangular at the tips, very oblique and slightly 

 undulating along the exterior border ; interior angle much rounded ; 

 second inferior vein not further from the third than from the first ; 

 third about four times further from the fourth than from the second.

 joint elongate, lanceolate, about half the length of the second. An-

 colouring, and in the hyaline spots of the fore pair it exhibits some 

 resemblance to the Saturnidce.
