the Trimytini, than that of Irichiotes or Oxygonodera in the 

 Triorophini. 



Of the other genera described by Mr. Champion, I can state 

 nothing positively at present, but it is possible that Soemias may 

 be a member of the Trimytini and Mencheres of the Euryme- 

 toponini. 



II. 



The South American genera of the Epitragini have not been 

 investigated systematically thus far, though a number of species 

 have been described by Berg, Fairmaire and others. As rep- 

 resented by material in my cabinet they may be known as 

 follows : — 



Mandibles bifid at tip ; elytra with punctured series throughout the 



width, acute at tip 3 



Mandibles truncate at tip 3 



2 — Epistoma broadly sinuate ; head without supra-orbital ridge, the 



eyes tiat and rather finely faceted ; prothorax sinuate at apex, with 

 the angles acute and somewhat anteriorly prominent ; tarsi with 

 short dense pubescence beneath. Atlantic South America, extend- 

 ing into Central America. [TyT^es fziscus Lat., aiirulentus Kirsch 

 and rigeiis Csy.] Epitragus Latr. 



Epistoma produced and rounded, with its apex narrowly and feebly 

 sinuate or sinuato-truncate ; eyes convex and prominent, coarsely 

 faceted, with fine supra-orbital ridges which are bordered inter- 

 nally by a depressed area somewhat as in Metopoloba^ the body 

 similarly polished and svibglabrous ; prothorax truncate anteriorly, 

 with obtuse and narrowly rounded or blunt and wholly non-prom- 

 inent apical angles ; tarsi with tufts of long dense pubescence be- 

 neath. Pacific South America. [Type P. solieri \\. sp.]. 



Parepitragus n. gen. 



3 — Prosternum produced, acute and received within a deep excavation 



of the mesosternum ; last antennal joint moderate, never longer 

 than the tenth ; front bisinuate, the middle lobe slightly advanced 

 and rounded; eyes flat, coarsely faceted, with very fine supra- 

 orbital carinas which are not bordered internally by a depressed 

 area; prothorax emarginate anteriorly, with acute and prominent 

 angles ; elytra very acute, with even punctured series throughout 

 the width; tarsi densely pubescent beneath. Atlantic South 

 America, extending into Central America. [Tvpe Epitragus 

 godtnani Champ. ] Epitragopsis Csy. 



Prosternum finely acute posteriori}* but only slightly produced, not 

 entering the large and deep mesosternal excavation, which remains 

 unaltered ; last antemial joint elongate, as long as the two prcccd-
