A stout-bodied, rather large f<jrni of Cercopidae, not very far 

 removed from the tertiary Palecphora Scudd., of Colorado, and 

 somewhat resembling the existing Philiienus St;ll, of the Old World, 

 but wnth distinctive neuration of the tegmina, in that the radial vein 

 forks at the middle of the wing, and that the transversals near the 

 tip of the wing form between the radial forks and the interspace 

 between the radial and ulnar veins, but not between the ulnar forks, 

 a double set of similar and small cellules a little longer than broad. 



A single species occurs. The name is given in honor of Dr. 

 George M. Dawson.

PI. I, tig. 10. 



A crushed body with displaced parts shows nothing characteristic 

 except a very broad head and the two tegmina, one of them turned 

 end for end. These show the peculiar neuration described under the 

 genus. They are slightly more than two and a half times longer 

 than broad, with a very gently convex costa, tapering rapidly in the 

 apical fourth so that the apex is sharply rounded with six or seven 

 apical cells around its narrowest part ; the tegmina are mostly very 

 dark brown, but a more or less distinct, moderately broad, pallid belt 

 crosses the middle of the wing, most distinct in the costal half, 

 and all the cells are more or less conspicuously pallid, excepting at 

 the veins.

This name is proposed for an insect of large size, apparently 

 belonging to the Cerco})id», but imperfectly known. Only the basal 

 half or more of the tegmina is preserved, but this shows a very
