Described from two specimens collected by August Busck. The 

 type is labeled " Trinidad, W. I., June," and the paratype " Port of 

 Spain, Trinidad, June 19." 



The species is closely allied to siibgldber Fisher, but can be easily 

 distinguished from that species by the shape of the pronotum, which 

 is widest at about the middle and arcuately rounded, while in suh- 

 glaher it is obliquely dilated to the base, where it is the widest. It 

 might also be confused with tenuis Fisher, but that species has a dis- 

 tinct lateral carina on the elytra. 



TAPHROCERUS AENEOCUPREUS, new species 



Form rather broadly elongate, strongly attenuate posteriorly, 

 moderately convex above, shining, uniformly aeneous, with a slighi 

 cupreous tinge in certain lights, and without pubescent spots: be 

 neath more olivaceo-aeneous than above. 



Head slightly narrower than pronotum at base, and when viewed 

 from above is transversely truncate in front, with an obsolete longi 

 tudinal groove, which is shallow and broad near the epistoma, but 

 becoming very narrow and resembling a carina on the vertex and 

 occiput; front wide, with the sides nearly parallel and very feebly 

 convex between the eyes ; surface densely, coarsely granulose, coarsely 

 and sparsely punctate, the punctures very shallow and distinctly 

 separated, and clothed with a few very short, cinereous hairs; eyes 

 large, elongate, more acutely rounded beneath than above, strongly 

 convex, and slightly projecting; epistoma slightly elevated and 

 broadly arcuately emarginate in front. 



Pronotum moderately convex, two times as wide as long, apex and 

 base nearly equal in width, widest at apical third ; sides when viewed 

 from above are strongly obliquely expanded from the anterior 

 margin to apical third, then obliquely attenuate to the posterior 

 angles, which are obtusely angulated; anterior margin obsoletely 

 rounded; base truncate to middle of elytron, then turning obliqueh' 

 backward to the scutellum, in front of which it is rather deeply 

 arcuately emarginate ; surface with a narrow, shallow, transverse de- 

 pression along the anterior margin, and with a broader transverse 

 depression behind the middle, connected on each side to the anterior 

 depression, the surface with a few coarse widely separated punctures, 

 from the center of which arises a short inconspicuous cinereous 

 hair, the intervals finely and densely granulose. Scutellum tri- 

 angular, rounded in front, acuminate behind, and with the 

 surface finely, densely granulose. Elytra moderately convex, 

 slightly wider than pronotum at base; humeral angles obtusely 

 angulated; sides strongly sinuate from the humeral angles to 

 middle, where they are broadly rounded and about equal in width
