HOMOPTERA. 57 



PCECILOPTERA DIFFINIS. 



Fcem. Testaeea, albo tomenlosa ; frons longa, perangusta, margine valde 

 elevato ; alec alba, tomentosce ; anlicce lituris Iransversis gutlisque 

 nigris, costa bad cotivexa, margine exteriore subconvexo, angidis 

 rotundatis, venis plurimis, venulis transversis paucis. 



Female. Testaceous, with white tomentum. Vertex and front com- 

 pressed, with much elevated borders; vertex very small; front long and 

 very narrow ; face long and narrow. Prolhorax transverse, short, slightly 

 conical in front. Wings white, tomentose. Fore wings with black trans- 

 verse marks on the basal half, with a black subapical dot, and with a row 

 of minute black dots along the fore part of the exterior border ; veins 

 rather numerous ; transverse veinlets few ; costal veinlels long, oblique, 

 successively decreasing in length towards the tip ; costa convex near the 

 base, straight from thence to the tip, which is rounded ; exterior border 

 slightly convex ; interior angle rounded. Length of the body 3 lines ; of 

 the wings 10 lines. 



This species may form a new genus, for it resembles Delphax in the 

 shape of the head, and recedes much from the typical form of Pceciloptera.
