broadly rounded, side margins short, oblique, carinate, distinctly shorter 
than distance between ocelli, claval margin long, posterior margin deeply, 
narrowly emarginate; elytra coriaceous, slightly more than twice longer 
than wide, convex and inflated, widest across the discoid cells, costal 
margin sinuated and strongly reflexed just before the middle, venation 
irregular, ramose, the two veins on the corium forking to form discoid 
cells, which are broken up posteriorly to form an irregular network, which 
occupies the entire apical portion of the elytra, the entire venation 
obscured by a dense covering of fine hair. 
This genus includes two rather anomalous species; from the 
ramose venation they might be placed next the Cercopincs, 
while in other characters they fall between Lepyronia and Pliilce- 
nus; from PliilcBnus and Aphrophora they may be readily 
separated by the dense prostrate pubescence and the venation, 
and from Lepyronia by the sulcate vertex. The genus is 
apparently confined to this continent and probably to the 
temperate zone, within which they are quite widely dis- 
tributed. 
The two species are still more remarkable in that they bear 
almost exactly the same relation to each other that the two 
species of PMlcenus do, spumarius and abjectus each possessing 
convex elytra and the forked wing vein, while Uneatus and 
Mlineatus are elongate and nearly parallel margined, with the 
third vein of wing entire; in color the resemblance is still 
greater, Mlineatus being almost a duplicate, on a larger scale, 
of Uneatus^ even the variation in color following the same lines; 
while abjectus, in some of its lighter shades, exhibits traces of 
the maculation of a typical spumarius, and the darker ones 
differ by scarcely a shade from its darker varieties. 
SYNOPSIS OP THE SPECIES. 
A. Elytra convex, the costal margins strongly curved, much wider than 
across eyes, front not produced anteriorly, the outline a regular 
curve; third longitudinal vein of wing forked; color, reddish- 
brown. abjectus Uhl. 
AA. Elytra with the costal margins nearly parallel, very little wider 
than across eyes; front, anteriorly produced, rapidly rounding 
to the vertex; color, pale straw-yellow, sometimes heavily 
marked with fuscous, costal margins lined with white.
