but rather more advanced than in E. minor. De Castelnau's 

 brief note on Sc. hopei, which cannot be called a description, also 

 gives me the impression that it should have the prothorax more 

 rounded behind than E. minor, not less so, as in E. politus. 



EURYSCAPHUS CONCOLOR, n.sp. 



Robust, black, shining ; elytra very convex, broadly rounded 

 at apex, impunctate. 



^. Head subquadrate, transverse (6 x 8-75 mm.), smooth; 

 frontal sulci connected behind by a faint curved impression, sub- 

 parallel forward, curving obtusely out in front in a sinuous 

 course ; pre-ocular sulcus well marked, oblique ; eyes round, rather 

 prominent ; lower margin of orbit lightly and obtusely projecting 

 in front; one supra-orbital puncture on each side. Antennae 

 filiform ; apical joint narrow, fusiform. Prothorax short,, trans- 

 verse (6*5 X 11-5 mm.); sides rounded; anterior angles broadly 

 and lightly advanced ; anterior margin lightly sinuate ; posterior 

 angles rounded, but strongly marked ; base short, bisinuate, the 

 middle broadly and lightly produced backwards ; border wide, 

 reflexed, very strongly so at posterior angles, narrow with an 

 obsolete median sinuosity on middle part of base ; marginal 

 channel wide ; median line lightly impressed ; a transverse striola 

 defining basal part ; two marginal punctures on each side, as 

 usual in the genus. Elytra broad (13-5 x 13'25mm.), strongly 

 rounded on sides and at apex, very convex ; base broadly and 

 decidedly emarginate ; humeral angles well marked, almost square; 

 margin narrow on sides, wider towards apex, wide and flat behind 

 shoulders ; border reflexed, very strongly so at shoulders, extend- 

 ing past humeral angles, not ending in a thickened humeral 

 projection ; a row of small punctures on base of each elytron ; a 

 row of lightly impressed punctures along lateral margins ; suture 

 linear, not deeply impressed. Prosternum widely channelled 

 between the coxse. Anterior tibiae bidentate ; three small teeth 

 above the two large ones. 



Length 30, breadth 13*25 mm.
