The only other described species of this genus (A. ventricosus, 

 Boh., from the Neilgherries) is differently coloured, and has the 

 elytra shortly ovate and subglobose. I have another species from 

 Eangoon. 



Dystirus. 

 (Leptopinse) 



JRostrum robustum, angulatum, versus apicem incrassatum ; scrobes 

 arcuata3, infra et ab oculis desinentes. Scapus breviusculus ; 

 funiculus 7-articulatus, articulis quinque ultimis transversis, 

 subsequalibus ; clava adnata. Oculi ovati, liberi, infra acumi- 

 nata Prothorax transversus, utrinque calloso-dilatatus, lobis 

 ocularibus distinctis. Scutellum invisum. Elytra ovata, pro- 

 thorace haud latiora, angulis anticis obsoletis. Femora modice 

 incrassata; tibia rectse, posticse corbulis cavernosis; tarsi 

 articulis tribus basalibus apice utrinqne spinoso-productis, infra

This genus appears to me to be most allied to the Australian 

 Leptops, its chief differential character lying in the remarkable 

 form of the prothorax, and the club closely attached to the funicle ; 

 the elytra also have no projection or tooth at the shoulder as in 

 Leptops.

 mento squamisque griseis, unguiculis nitide nigris exceptis, tectus ; 

 rostro capite fere duplo longiore, supra longitudinaliter fortiter trisul-

 secundo breviore, clava articuloque ultimo funiculi nigris, pilosis; 

 prothorace irregulariter grosse foveato, interspatiis callosis; elytris
