FOSSIL CERCOPID.^: (HOMOPTERA). 
By T. D. a. Cockh:re:ll. 
In the Miocene shales of Florissant, at Station 14, we found 
an excellent specimen of Palaphrodcs irregularis Scudder, pre- 
served in exactly the same position as Scudder's fig. 6, PI. 21 
(Tertiary Insects), and showing the characteristic 'form and mark- 
ings. It is a little smaller than the typical size — not quite 10 mm. 
long. Curiously, however, the venation of the wings (hind 
irregularis Scudder. in the Scudder Collection for the original of 
his fig. 6, but failed to find it; and I do not 
know whether to consider the cross-vein an error of the artist's, or 
not. Scudder's description certainly agrees with his figure. I 
consulted Mr. Otto Heidemann on this point, and he very 
kindly wrote me at some length, also sending a series 
of Cercopidse for comparison. Mr. Pleidemann justly ob- 
serves, that according to Scudder's description and figure, 
the venation of Pnlaphrodes does not accord with that of 
the Aphrophorinae, to which it is assigned. My specimen, how- 
ever, does so accord, and there is no doubt that the genus is very

Using the nomenclature set forth by Kirkaldy 
(Leaf-Hoppers and their Natural Enemies, 
1906), Scudder's figure shows the cubitus ap- 
parently simple, but with a cross-vein (which 
may represent the lower branch of the cubitus) , 
going to the first anal. (Fig. i, lower figure). 
Our specimen, on the contrary, shows the cubi- 
tus evenly forked, with no cross-vein to the 
anal. When at Cambridge, I sought diligently
