It is closely allied to P. anthracinus from which it may be 

 distinguished by its more protuberant eyes, more cordate prothorax, 

 less convex elytra, &c. 



Promecoderus anthracinus. 



P. anthracmios, Macl. I.e. p. 334. 



(J. — Shining black with a slight metallic lustre ; tarsi, palpi, 

 and antennae piceous. Head rather small, smooth ; the clypeal 

 suture faint ; vertex with the transvei'se impression very wide 

 and shallow ; eyes not prominent, inclosed behind ; the post- 

 ocular prominences wide, about half the length of the eyes. 

 Prothorax rather cordate, transverse (4 x 4:h mm.), convex, 

 strongly rounded on the sides, widest just behind the anteiior 

 marginal puncture, very slightly declivous behind ; mai-ginal 

 border hot sinuate before the basal angles, entire on the base ; 

 the basal angles shar[)ly marked, though hardly right angles, the 

 median line lightly impressed ; the anterior and posterior trans- 

 verse impressions well marked. Elytra rather short, oval 

 (7f X 4f mm.), hardly narrowed "at the base and broadly rounded 

 behind ; the stria next the suture complete, the rest of the elytra 

 smooth, though under a lens faint traces of striee are visible. The 

 four last ventral segments with a broad foveiform impression on 

 each side. Anterior tarsi with four first joints broadly tri- 

 angular ; three first of the anterior and two hrst of middle tarsi 

 spongiose below ; the trochanters short and very bluntly pointed 

 at the ai^ex. 



9. — More bronzed in colour, with the prothorax less rotundate 

 on the sides (3| x 4| mm.), and more narrowed behind ; the 

 elytra proportionately broader in the middle, less broadly rounded 

 behind, and more decidedly substriate.

Nearly allied to P. howitti, from which it differs in its more 

 robust form, the ^ with shorter and more transverse prothorax, 

 shorter elytra, and more bluntly pointed trochanters ; they are 

 very "close" species
