Ferruginous, broad, thick: feelers yellow, submoniliform, 

 rather stout, less than half the length of the chest, with brown 

 tips, which have two bristles ; joints successively decreasing in 

 length : legs tawny ; shanks yellow : wings colourless ; fore-wings 

 broad ; fore border convex near the base ; veins with alternate 

 yellow and brown bands ; upper fork at two-thirds of the length of 

 the wing ; lower fork in the middle of the length, its petiole ex- 

 tremely short. The breadth of the body and the structure of the
