Genus CCCCXXIII. — Sarroteidm, Illiger. 



Antennae short, thick ; 10-joiiited, the three basal joints rather slender^ the 

 second and third being- semiglobose, the remainder forming a suboval-fusi- 

 form, slightly compressed and curved club, of which, the six basal joints are 

 transverse, very short in proportion to their length, lentiform, and furnished 

 with elongate pile and hairs, the terminal joint subglobose, with the base 

 truncate. Palpi four, short, unequal ; the maxillary with the terminal joint 

 rather thickened, ovate, obtuse : maxiUcB membranaceous at the apex, bifid : 

 mandibles acutely bidentate : labium exserted, entire: body elongate- 

 quadrate, sublinear: Aead and ^/torao; quadrate : e/«/^ra elongate, sublinear, 

 with the apex rounded : legs short, stout ; tibi(E subcylindric, armed with 

 very short spurs ; tarsi short, quadriarticulate. 



The singularly constructed pilose 10-jointed antennae of this 

 extraordinary genus, united to its quadriarticulate tarsi, and elongate, 

 narrowed, body, at once point out the distinctions of this genus from 

 its allies.
