A genus of somewhat doubtful position, agreeing with the Cfenos- 

 celhuc in the spinose tibia? and the foi'in of the sternal pieces and 

 mandibles, but differing from them entirely in the antennae, whicli arc 

 much like those of a Cj/rtognatlius {e.g., G.forficatus'). The thorax 

 may be taken as essentially of the same structure as that of Gtenoscelis, 

 but witli its chief characteristics less strongly pronounced ; the sculp- 

 ture of the surface is not very different from that of Ct. dijrraclms, ^ , 

 but the lateral crenulations are very faint, and the anterior angles are 

 not advanced or distant from the neck, whence the sides are rounded 

 so that the widest part is at two-thirds the length.

 cl ytris fulvo-castaneis ; capite antice (cum mandilml is) spnrsim punc.tato,

 nitido ; elytris tenuissime rvguJoso-punctatis, sub-nitidis ; abdomine 

 piceo-rttfo, ginbro. Long. 1 ioi. 9 lin., ^ . 



In general form and proportions similar to Gtenoscelis oter, but 

 nnich smaller, and differing conspicuously (besides colour) in the nar- 

 row thorax, with its anterior angles obtuse and not remote from the 

 sides of the head. The elytra are tawny rust-brown, the rest of the 

 body being dark piceous, with the legs and the abdomen a little redder. 

 The antenna? are only two-thirds the length of the body, robust, and 

 sub-serrated ; the short 12th joint is distinctly articulated ; the 1st 

 joint is short, and forms a thick curved club ; the porose concavities 

 of the joints begin at the outer apex of the 3rd joint, and become suc- 

 cessively larger until they occupy the whole outer sides of the terminal 

 joints. The anterior legs are shorter than the others, and the tibia) 

 relatively much broader. 



One male example only ; from the Province of Parana, in Brazil.
