No. 2313. NEW SPECIES OF EOCENE INSECTS— COCKERELL. 245 



large hyaline spots, about equidistant, on costa; three hyaline spots, 

 successively larger from above down, on outer margin, the first about 

 1.5 mm. from apex; three broad oblique bands, more or less broken 

 into spots, and not conspicuous (owing to the palHd ground), across 

 the disk of the wing; there is perhaps a fourth band near the base. 



Type. — Green River shales back of house of Smith's Ranch, in the 

 vicinity of Cathedral Bluffs, Colorado. (Winchester 17-3, U.S.G.S.) 



HGlotypc— Cat. No. 66562, U.S.N.M. 



Among living Fulgoridae this recalls the species of Ricanio., but 

 the wings are differently shaped. 



CALLOSPILOPTSRON, new genus. 



Anterior wings broad, mth obtuse ends, shaped much as in the 

 Neuropterous Dilar, but with a distinct anal angle, and without 

 the subbasal enlargement of costal region; apex obtuse; veins 

 very numerous, not branching as they approach the margin; sub- 

 costa ending beyond middle of wing, but before beginning of last 

 third, its apical end bending downward and emitting three very 

 oblique veins, beyond which are seven or eight very oblique \eins 

 to the margin, arising from the radius. The genus is noteworthy 

 for the reduced costal region, with consequently very oblique veins 

 leaving the subcosta and radius; also for the relatively short sub- 

 costa. The wings carry an ocelliform spot near the outer margin, 

 som.ething like the spots on the hind wings of Psychopsis. 



Type. — Callospilopteron oceUatum, new species. 



CALLOSPILOPTERON OCELLATUM, new species. 



Plate 33, fig. 7. 



Anterior wings 13 nmi. long and about 6.4 mm., wide; fuliginous,^ 

 with a round black or dark fuscous spot, about 1 mm. wide, not 

 far from outer margin; this spot having a pale circle around it, 

 which is enlarged above into a more or less distinct hyaline spot 

 surmounting the dark one. The dark spot is 3 mm., below the 

 costa and about 2.5 mm. from apex of wing. Three simple veins 

 pass from the spot to the margin, and below this are about 13 

 parallel simple veins running to margin, between the spot and the 

 anal angle. The subcosta ends about 8.7 nam. from base of wing. 



Type.—V.S.G.S. 1133. Green River, Wyoming (Scudder col- 

 lection). 



IlGlotype.—Q&i. No. 66563. U.S.N.M. The spot on the wings is 

 strongly suggestive of that on the oriental Melandeva oceUata Dis- 

 tant, but it is not in the same plac€. The venation is very different 

 from that of Melandeva.
