68. PSYLLA? LATA. 



Ferruginea, lata ; antenna flavce, submoniliformes, thoracis di- 

 midio breviores, apice fuscce ; pedes fulvi; tibiis jlavis ; alee 

 limpidce, venis flavo fuscoque fasciatis. 



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 

 feelers and of the fore-wings, distinguish this species from all the 

 groups into which this family has been divided; it is most allied to 

 Rhinocola. Length of the body lj line; of the wings 3 lines.
