broadly rounded, side margins short, oblique, carinate, distinctly shorter 

 than distanca 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"" Cereopime, 

 while in other characters they fall between Lepyronia and Phike- 

 nvs: from-'" Philcenus 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 Phikenus do, simmarius and abjectus each possessing 

 convex elytra and the forked wing vein, while Uneatus and 

 bilmeatu.s are elongate and nearly parallel margined, with the 

 third vein of wing entire; in color the resemblance is still 

 greater,^ bllineatus being almost a duplicate, on a larger scale, 

 of lineatus, 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 spiunarius, and the darker ones 

 differ by scarcely a shade from its darker varieties. 



SYNOPSIS OF 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.
