confused elytra] sculpture, have the middle lobe of the mentum 

 broader and the lateral lol.es Less distinct than in the other 

 groups of species: the middle lobe is broadly rounded in front, 

 and iu the present species is slightly transverse, with the lateral 

 lobes small, inflexed, and scarcely visible ; thus approaching the 

 new genus Discogenia, in which they disappear entirely. 



E. clawcomis makes an exception to the other small species, 

 which requires it to be separated as a distinct group : the middle 

 lobe of the mentum is prominent, elevated, and triangular as in 

 the larger species of the genus.

Eleodes scabricula Lee, and marginata Esch., differ from the 

 other species which have been referred to the genus, by the 

 mentum being quite flat, not at all trilobed, but transverse, 

 widened from the base to the middle, then rounded, both at the 

 front and sides, the lateral angles being also rounded at tip; the 

 surface is punctured, aud is foveate each side near the lateral 

 angle. The thorax is broader than long, niueh rounded and finely 

 margined at the sides, with the hind angles not prominent ; it is 

 feebly emarginate in front, with the front angles marly obtuse. 

 The elytra are oval, not wider than the prothorax, pointed behind, 

 considerably rounded on the sides, and without humeral angles, 

 so that they are more distant from the prothorax than in any 

 species of Eleodes. The front thighs are unarmed, in the female, 

 slightly angukted beneath in the males; the tarsi are alike in 

 both sexes. 



But two species named above are known to me. 1 regard /:'. 

 fischeri Mannh. as a large and well developed form of /.'. 

 marginata.
