Plu/tophogous Coleoptera, ^'c. 241 



fovea, its anterior surface tliickened ; space between the 

 antennre also thickened ; eyes deeply notched, the notch 

 extending more than halfway across the disk ; antennae 

 filiform, about half the length of the body, the 2nd joint 

 short, the 3rd, 4th and 5tli equal in length, each twice as 

 long as the 2nd. Thorax twice as broad as long ; sides 

 slightly rounded and converging fi'om the base towards 

 the middle, the anterior angles slightly produced, thick- 

 ened, obtuse ; the hinder angles acute, produced slightly 

 baclvAvards ; lender margin obtusely truncate, obliquely 

 sinuate on either side within the lateral angle ; upper 

 surface slightly flattened on the hinder disk, finely ])unc- 

 tured ; sides distinctly margined ; on either side some 

 little distance within the r^argin is a longitudinal groove, 

 the space between which and the margin itself is thick- 

 ened and forms a broad longitudinal elevation, the apex 

 of which, just before reaching the anterior border of the 

 thorax, curves for a short distance abruptly inwards on the 

 disk. Elytra narrowly ovate, convex, finely punctured. 



Genus Cyclophysa. 



Corpus sub-rotundatum, valde convexum. Caput tri- 

 gonatum ; antennis filiformibus ; oculis elongatis, reni- 

 formibus, intus profunde rotundato-emarginatis ; encar- 

 pis contiguis ; cli/peo elevato, apice cuneiformi ; palpis 

 maxillaribus articulo peniiltimo incrassato, ultimo brevi, 

 conico. Thorax transversus, basi bi-impressus, lateribus 

 subrectis, angulis anticis oblique truncatis, margine basali 

 utrinque bisinuato. Elytra confuse punctata ; limbo 

 inflexo horizontali, concavo. Pedes robusti, breves ; 

 femoribus posticis valde, anticis quatuor modice incrassu- 

 tis ; tibiis a basi ad apicem incrassatis, dorso late canalicu- 

 latis, anticis quatuor mut^ois, posticis spina valida arma- 

 tis ; tarsorum posticorum articulo basali duobus sequenti- 

 bus asquilongo. UuguicuUs divaricatis, appcndiculatis. 

 Prosternum anguste oblongum, coxis anticis a^quialtum. 

 Mesosternum transverso-quadratum, apice emarginato. 



In the deeply- emarginate eyes, and in many other 

 characters, Cyclophysa agrees with Nephrica, v. Harold; 

 but it differs so entirely in the form of the body, which 

 closely resembles that of a SphcEroderwa, that I do not 

 hesitate to separate it from that genus.
