punctato ; antennis nigro-chalybeatis ; prothorace raodice trans- 

 verso, irregulariter punctato, pone medium rude biimpresso ; scu- 

 tello nigro, triangulari ; elytris manifeste costulatis, interstitiis

 nigro ; femoribus anticis infra subbidentatis. Long. 8 lin. 



JIab. West Africa (Gold Coast). 



These two species and 0. speciosus'^ differ from the type 

 {0. cupreus, Fab.) in their shorter chiw-joint, the prothorax 

 not denticulate at the sides, and greater breadth of the pro- 

 thorax. 



Cyriogeton. 



(Amarygminae.) 



Ab Amarygmo difFert : Lohi antennarii dilatati ; femora fusiformia ; 

 tarsi subtus dense pilosi. 



The antennary lobes (or orbits) not being in the form of 

 ears, this genus should, technically, be placed among the 

 Platygenous subfamilies of Lacordaire's second cohort of 

 Tenebrionidae ; it is, however, too nearly related to Amaryg- 

 mus to be separated from it more than generically. Of the 

 two other characters, there are some species of the latter genus 

 in which the femora are scarcely linear, or in which the tarsi 

 are scarcely ciliated, the cilia becoming hair-like and more 

 numerous. Amarygmus ceneus, Cast. (Hist. Nat. Ins. ii. 

 p. 234), is said to have the tarsi pubescent beneath ; it may 

 belong to Eurypera, to which also A. convexus may be re- 

 ferred. In the fine s})ecies described below the clypeus bulges 

 out, forming a transverse fold, which is continuous on each 

 side with the antennary orbits. 



Cyriogeton ins ignis. 



C. subellipticus, nitidissime cupreus ; capite infra oculos excavate ; 

 cly|)eo prominulo plicani transversani formantc : antennis nigris ; 

 prothorace lateribus postice parallcHs, supra fere impunctato ; scu- 

 tello triangulari ; elytris modice convcxis, sat obovatis, tenuiter 

 seriatim punctulatis, interstitiis latis, fere impunct;itis : coi'])ore 



* This is au unpublished name ; in Dejean's Catalogue it stand* as 

 Pezodontus spcciosus ; the following description will serve to distiuguish 

 it:— 



Odontopus fipeciosus. 



O. oblongus, modice courexus, nitide cyaneus, aliquaudo violaceus ; ely- 

 tris vel viridibus, vel cupreis, tonuiter costulatis, interstitiis crebre for- 

 titer punctatis ; corporo infra violaceo ; prosteruo latissinio ; femoribus 

 infra unidentatis. Long. 10-12 lin. 

 Hab. Gu:nea.
