Head \Aith the front and clypeus oblique and transversely 

 broadly concave ; the clypeo-f rontal sutures generally well marked ; 

 the clypeus finely marginate at the sides ; the labrum distinct, 

 generally large, united by a straight or slightly arcuate suture 

 with the coriaceous front edge of the clypeus. Eyes strongly 

 emarginate ; the lower lobes frequently large, but never extend 

 so to reach the front. Anteunoe inserted near the base of the 

 mandibles ; the third joint generally very long. Lateral margins 

 of prothorax curve downwards from the base and are more or 

 less closely approximated to the outer angles of the coxal cavities 

 and to the prosternal sutures, sometimes obsolete in front. 

 Intercoxal process of prosternuui arched. Epimera of prothorax 

 short, those of the metathorax obliquely truncate, scarcely pro- 

 longed behind. Epipleures of elytra exceptionally only (genus 

 Dandamis) wideued out below the shoulders. Third tarsal joint 

 cleft almost to the base, but with the lobes sometimes narrow and 

 exceptionally xery short.
