individual in wliicb tlie characteristic part of the venation appears ; 

 but whether it is identical with any of the species from the Florissant 

 tertiaries cannot be told on account of the incompleteness of the frag- 

 ment ; and on this account it has not seemed worth while to figure it.

AiMuiopiiouA Germar. 



Half a dozen fossil species from different parts of Europe, as well 

 as one from Florissant, have l)eei) referred to this group as typical of 

 the sub-family. The one here added not only certainly belongs to 

 the sub-family, but if not an Aphrophora proper, must be exceedingly 

 close to it, as the structure of the hind wings is almost identical with 

 that of A. aJni of Europe. 



Aphrophora sp. 



PI. I, fig. 4. 



The abdomen and the greater part of the hind wing of a single indi- 

 vidual are all that represent this species. The abdomen shows nothing 

 but some crushed tapering segments ; the wing is characteristically 

 that of Aphi'ophora, the second and third longitudinal veins bending 

 toward the transverse cross vein which unites them near the middle of 

 the apical half of the wing, the third and fourth being united by a trans- 

 verse vein near the middle of the wing (farther back than usual) and 

 the latter forked about midway between the two cross veins ; the 

 sixth and seventh veins, however, if united at all, are so only at the 

 extreme base of the wing.

Ptysmaphora (jzTfxTim. (pijHo) Gen. nov. 



This genus is peculiar among Aphrophorina? for the very early 

 forking of both the ulnar and radial veins, both within the middle of 

 the wing, and for the great length of the apical cells. The tegmina 

 are elongated and subequal, only tapering in the apical sixth, the apex 

 roundly pointed. The upper radial fork sends several shoots to the 

 costal margin in the apical half of the tegmina forming several mar- 

 ginal cells.
