This genus superficially resembles Trapezidera Crotch,- 

 but is easily distinguished by the difierently shaped thorax , 

 and the very different formation of the club of the an- 

 tennae , which resembles that of Pachylanguria Crotch ; 

 no species of Trapezidera has as yet been found except in 

 Tropical America.
