210 MANDIBULATA. COLEOPTERA. 



Genus CCCLIV. — Tropideres, Sch'onherr. 



Antennce slender, rather long, placed in the middle of the sides of the rostrum : 

 the two basal joints robust, slightly elongate ; five following slender, elongate, 

 obconic; the eighth short, subturbinate : the remainder forming a triarticulate, 

 elongate, distinct, club. Rostrum perpendicular, broad, flat, with the apex 

 more or less dilated, and subtruncate : e7/es large, entire, somewhat depressed 

 and sometimes approximating in front: thorax considerably narrowed in 

 front, the sides somewhat oblique, the base slightly bisinuated, with an entire 

 transverse carina a little within : elytra rather broader at the base than the 

 thorax, the sides straight, moderately convex, with the apex rounded: body 

 oblong. 



Tropideres differs from Platyrhirius by having the two basal 

 joints of the antennae somewhat elongate and stout, the five suc- 

 ceeding ones very slender, and also elongate : the eyes less pro- 

 minent : the rostrum of dissimilar form, and the bulk of the body 

 comparatively small.
