PEOTOLIARUS, new genus. 



Small Fulgoridae resembling Oliarus, but with no distinct thoracic 

 keel and no stigmatic spot. The veins are not spotted, as they are 

 in Cixius. The tegmina have a short but evident subcostal nervure, 

 running close to the costa for a short distance; radius soon emit- 

 ting the media, and immediately afterwards dividing into two main 

 branches, of which the uppermost bends dov/nward near the apex of 

 the tegmen (stigmatic region of Oliarus), emitting a series of veins to 

 the margin; media bifurcating before middle of tegmen, its lower divi- 

 sion branching more 

 than once again; cubi- 

 tus running parallel 

 with sutural, and close 

 to it, branching near 

 middle of tegmen ; sutu- 

 ral (first anal) as in re- 

 cent forms; the other 

 anals inclosing a long pointed cell, as is usual in recent forms. The 

 hind wing is only partly preserved, but the part visible is figured. 



Type. — ProtQllarus humatus, new species. 



PROTOLIARUS HUMATUS, new species. 



Plate 33, fig. 5. 



Length, 5 mm.; tegmina, 5.5 mm. long and 2 mm. wide, extending 

 slightly over 2 mm. beyond abdomen. 



Type. — Green River shales (Eo- 

 cene), back of house at Smith's 

 Ranch, in the vicinity of Cathedral 

 Bluffs, Colorado. (Winchester 1 7.3, 

 U.S.G.S.) 



Holotype.— C Sit. No. 66560, 

 U.S.N.M.' 



This may possibly be congeneric 

 with Scudder's Oliarites, but it 

 seems to be distinct. The characters of Oliarites are imperfectly 

 known, and its status as a genus can not be precisely determined. 



SCOPARIDEA, new genus. 



Tegmina shaped and spotted much as in the Lepidopterous genus 

 Scoparia, the costa nearly straight except at base, the apex obtuse, 

 the outer margin oblique; subcosta leaving costa nearly 1 mm. from 

 base, and entering it about 1.3 mm. beyond, thus inclosing a very 

 narrowly lanceolate cell (a condition approached in Cixius); radius 

 parallel with costa, but a considerable distance (about 6 mm. in the
