200 TERTIARY INSECTS OP NORTH AMERICA. 



tling; the discoidal cell is very long and slender, nearly one-tliird 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 running almost 

 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 chai-acters in opposition to it. They show in 

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

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

 base. 



Length of body, 8"™ ; of front wing, 8.26°"" ; breadth of same, 3.25"'" ; 

 ength of hind wing, 7"™. 



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