1/ FuLGORIDiE (HeMIPTERA). 



C7 EoFULGORELLA, gen. nov. 

 A small Fulgorid, with comparatively elongate tegmina, the costa 

 arched basally, but gently concave about the middle ; outer margin 

 very oblique. The venation is very well marked by dark lines, the 

 veins being broadly pigmented. The homologies of the different 

 veins in various genera of Fulgoridse seem to be rather obscure, but 

 as I interpret them in the present case, the venation is as follows : 

 subcosta distinct from radius, ending on costa a little beyond the 

 middle of the, and having one oblique branch to, costa ; radius 

 straight, branched terminally as shown in the figure ; media branch- 

 ing beyond middle of wing, and enclosing a small fusiform cell ; 

 cubitus branching near middle of wing ; two cross-nervures from 

 cubitus to media, and two from cubitus to first anal, the latter before 

 middle of wing ; series of gradate veins in the subapical field very 

 well marked, consisting of a series of oblique transverse veins, one 

 following the other, between the longitudinal nervures. 



I failed to associate this with any living or fossil genus, and 

 so sent a sketch to Mr. E. P. Van Duzee, who kindly replied that 

 it agreed with nothing known to him. It has a general resem- 

 blance to'^Oliarus and its allies, but is remarkable for the shape 

 of the tegmen and the regularity of the gradate veins. 



Eofulgorella bradburyi, sp. nov. 

 Tegmen about 8 mm. long and 2f broad ; with dark veins, and the 

 apex broadly infuscated. No other parts preserved. 



Eofulgorella bradbiinji. 

 S.C. = Subcosta. E. = Radius. M. = Me(iia. Cu. = Cubitus. A. = First Anal. 



Hab. Eocene shales about six miles north of Rifle, Cororado ; 

 received from Dr. S. M. Bradbury. The locality is the same 

 as that from which Philorites and other Diptera have been 

 described. 



AORIONIDiE (OdONATA). 



Enallagma mortiiella, sp. nov. 

 Head and thorax black ; abdomen, at least as far as middle, warm 

 red-brown above, pallid at sides, a ventral band and the sutures darker 

 brown, no sign of any black saddles on the distal ends of the seg- 

 ments, such as are usually seen in modern species. Legs pale red- 

 dish, the femora at least largely black, the tibise with short black 

 bristles, quite as in the living species. Wings clear, the veins black 

 or almost ; stigmata warm red-brown with heavy black margins, alike 

 on upper and lower wings. Length of anterior wings 19 mm., nodus 

 to centre of stigma 11 mm.; length of posterior wings llh mm.; 

 eleven postnodal cross-veins in anterior and nine in posterior wings.
