protuberant but not spined at the side, will probably form the 

 type of a new genus. Stenoderus concolor, M'Leay (King's 

 Voyage, ii. 452), with which Lacordaire identifies B. leptu- 

 roides, is a true Stenoderus.

 oribus, illo in medio canaliculate) ; rostro longitudine paulo latiore, 

 planato-marginato ; antennis leviter piloso-firabriatis, articulo 

 tertio quam sequentibus multo breviore ; prothorace latitudine 

 sesquilongiore, postice gradatim latiore, pone apicem parum incur- 

 vato, supra lineis duabus pilosis notato ; scutello subrotundato ; ely-

XUTHODES. 



Caput breve, inter oculos sulcatum. Oculi magni, supra distantes. 

 Antennae corpore longiores, tenuiter ciliatae, articulo basali ob- 

 conico, tertio fere aequali, quarto paulo breviore, quinto ad unde- 

 cimum longioribus. Prothorax antice late truncatus, utrinque 

 bituberculatus, tuberculo anteriore apicali, altero mediano, disco 

 inaDquali. Elytra oblonga, parallela. Pedes mediocres ; femora 

 fusiformia. Prosternum angustum, arcuatum. 



In habit and colour the only representative of this genus is 

 like the Chilian Phymatioderus bizonatus ; but its characters 

 ally it with Grammicosum and Hesperoplianes 1 from both of 

 which it differs in the prothorax and antenna.

 luteis; prothorace impunctato, disco 5-tuberculato. Long. 7|
