In this group the body is more or less oval, the thorax 

 never exceptionally long, the beak never extremely long and 

 slender; thorax and elytra more or less covered with scales and 

 with hairs that may be simple, emarginate or thickened. 



The head is small and round, with the beak or rostrum well 

 developed, often with a carina or keel on the upper surface; 

 antennae set in a groove on the side of the beak, the groove 

 usually slopes downward toward the lower side of the eyes; 

 antennae (PI. XXIV, fig. 17), composed of twelve joints, a long 

 scape, seven funicle joints, the first two of which are longer 

 than any of the others, and a four-jointed club, the antennae 

 rarely reach to the middle of the prothorax; eyes oval, round or 

 elongate-oval, often narrowed below, rather large and close 

 together in front; mouth parts at the apex of the beak as usual, 

 labrum wanting, mandibles, (PI. XXIV, fig. 3, 4, 15), often with 

 fine punctures, broad, stout, more or less pincer-shaped, with 

 teeth, maxilla (PI. XXIV, fig. 1, 16) broad, with short, conical 

 four- jointed palpi which are rigid and taper more or less to a 

 point; lacinia provided with stout teeth and rather long hairs, 

 apparently always with short spines on the inner surface; 

 submentum nearly rectangular, emarginate; mentum short and 

 broad, labial palpi (PI. XXIV, fig. 2) three-jointed, rigid, 

 conical. 



Prothorax more or less rounded above as seen from the side, 

 sides usually somewhat swollen, anterior and posterior margins 

 rarely as wide as the middle; oval, transverse-oval or elongate; 

 always with a short process below between the front coxae. 



Scutellum always minute. 



Elytra differing greatly in form, sometimes at least three 

 times as long as the thorax, in other species less than twice as 

 long, elongate; oval, broad or obovate; from the side usually 

 rather flat at the base, often rising for a short distance, and 

 then may be abruptly declivous or rounded to the apex; 10 

 striae and 11 interspaces including the sutural and side spaces.
