JEGOSOMINI. 41 



$ . Antennae and legs shorter and more slender than in the 

 male and scarcely asperate. Pronotum closely and very coarsely 

 punctured, dull at the sides, less closely punctured, in part im- 

 punctate, in the middle and glossy. Hind breast entirely covered 

 with a faint tawny pubescence. 



Length 30-50 mm. 



Hob. Andaman and Nicobar Islands. 



Group ^GOSOMINI. 



Head with the front and clypeus oblique and transversely 

 broadly concave ; the clypeo-f rental 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. Antennae 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 prosteruuin arched. Epimera of prothorax 

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

 longed behind. Epipleures of elytra exceptionally only (genus 

 Dandamis) widened out below the shoulders. Third tarsal joint 

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

 exceptionally very short.
