close to Aphrophora, that is, Cercopis, according to Horvath, 
Kirkaldy, etc. The principal distinctive character may be found 
in the shape of the head, — very obtuse and rounded in front, and 
distinctly narrower than the thorax. The pattern of the tegmina 
is perfectly typical of C ere o pis (Aphrophora) or Lepyronia — 
these two having essentially the same pattern. The venation of 
the wings, at least in my specimen, is entirely that of Cereopis 
(Aphrophora) . The recent species compared are Cereopis sarato- 
gensis (Fitch), C. parallela (Say) and C. quadrinotata (Say). In 
Ball's figure of the wing of Aphrophora in Pr. Iowa Acad. Sci. 
1895, the cross-vein between the media and cubitus is omitted, but 
it is present in the specimens examined, and doubtless its omission 
was accidental. 
We obtained Paleephora eommunis Scudder at Stations 14 
(W. P. Coekerell) and 17 (S. A. Rohwer), and P. prcevalens 
Scudder at Stations 13 (T. D. A. Coekerell) and 14 (W. P. Coek- 
erell, Geo. N. Rohwer). This genus has longer and slenderer 
tegima than Palaphrodes, with the costa less arched. The pattern.

figured by Scudder for P. marvinei Scudder, is in essential 
agreement with that of Cereopis, but is noteworthy for 
the rather numerous distinct nervures passing from the radius 
to the costal margin. The tegmina are rounded at the apex, not 
pointed. The hind wings, as well seen in our specimens of P. 
communis, are in general agreement with Cereopis, but offer a 
distinctive feature in the deflection downwards and bending of 
Cug (see fig. 2). The relation of the radius to the media varies; 
it may be connected by a cross-vein as in Cereopis, or it may act- 
as Scudder remarks, is dis- 
tinctive, though it could be 
derived from that of Cer- 
eopis without any very 
tion of the tegmina, as
