200 TERTIARY INSECTS OF NORTH AMERICA. 



tling ; the discoidal cell is very long and slender, nearly one-third the 

 length of the wing, and occupying almost exactly the middle third longi- 

 tudinally. First apical .sector arising from the middle of the discoidal cell ; 

 cell between the sector and cubitus of uniform width and runnino- almost 



o 



exactly through the middle of the wing, terminating some way below the 

 apex; cross-veins uniting the sector and cubitus more than half-way from 

 the e d of the discoidal cell to the border. As the other cross-veins are in 

 their usual place, the anastomosis is widely scattered, whence the specific 

 name. 



The other specimens are poorly preserved; they agree with the pre- 

 ceding in size and present no characters in opposition to it. They show in 

 addition portions of the antenna', a slender stem arising from a rather stout 

 basal joint; in both, however, the antenna' are broken shortly beyond the 

 base. 



Length of body, S" mi ; of front wing, 8.25"""; breadth of same, 3.25 mm ; 

 ength of hind wing, 7 11 "". 



Florissant. Three specimens, Nos. 809, 8606, 8995.
