line, the whole surface is closely and finely punctulate ; prothorax 

 sub-parallel, with the basal angles oblique, base slightly marginate 

 and bi-sinuate on each side of the median part, sides aciculate, 

 median part smooth or very obsoletely aciculate ; elytra oblong, 

 very briefly and sparingly pubescent, narrowly striate, the strise 

 geminate, intervals convex, tectiform, slightly aciculate, the seventh 

 stria stops short of the base, the eighth is obliterated for about one- 

 fifth of the length, the ninth is longer than the eighth, and unites 

 with the marginal one at some distance from the base ; anterior tibiae 

 strongly tri-dentate outwardly, and quadri-serrate above the digits ; 

 under side normal.

Aphodius (Oxyomus) medioximus, n. spec. 



Brick-red, nearly glabrous, but with a very slight pubescence in the 

 posterior part of the elytra; it very much resembles A. piiherulus, 

 but the head has no impressed, transverse line; the prothorax is dis- 

 tinctly aciculate all over, the aciculation being, however, denser and 

 deeper on the sides ; the striae on the elytra are much more distincth' 

 geminate and the costse are more sharply carinate and more dis- 

 tinctly punctate on each side.

Black, sub-opaque, very convex, glabrous ; antennae black ; clj-peus 

 a little sinuate in front, and with the sides very oblique, genge auricu- 

 late, triangular, head simple but having a slight median impression 

 in the anterior part of the clypeus, and a not well-defined median 

 elevation, it is covered with deep, nearly confluent punctures, 

 and the intra-ocular transverse line is not distinct ; prothorax sub- 

 parallel and with the posterior angles very little produced diagonally 

 towards the base which is not marginate, deeply foveato-punctate, 

 and slightly scrobiculate laterally- ; scutellum somewhat short ; 

 elytra very sharply carinate with the intervals moderately broad, 

 and filled with transverse punctures divided into two by a verj- fine 

 longitudinal impressed line, the carinae reach the apex except the 

 fourth, sixth, and eighth, which are much shorter, and the eighth and
