CHALCOPHANINiE. 



This is one of the best defined groups on account of 

 the base of the presternum being either bilobed or con- 

 cave. In Chalcophana proper the sides of the thorax: 

 are rounded, but in Otilea they are dentate. Here more 

 than in any other group is it essential to distinguish the 

 sexes, as the females very frequently have costate elytrn, 

 this character being wanting in the males. Cyclirca, Baly, 

 cannot, I think, be separated from Chalcophana as has 

 been done by Lefevre, but Erij)hyle may be justified as 

 a distinct genus on account of the distinctly widened 

 terminal joints of the antennae. 



Otilea fulva, sp. n. 



Mas. Elongate, entirely fulvous, tliorax angulate at the sides, 

 remotely and irregularly punctured, elytra strongly subgeniinate 

 punctate-striate, the interstices longitudinally costate. 



Fern. Thorax broader, the elytral costae much more strongly 

 raised, the interstices rugose at the sides. 



Length 6-8 millim. 



Mas. Of elongate, posteriorlj' pointed shape, the head very finely 

 punctured, with a central h)ngitudinal groove, the clypeus sub- 

 quadrate, with a few deep punctures, antennte long and slender, 

 extending to the apex of tlie elytra, entirely fulvous ; thorax twice 

 as broad as long, the sides strongly angulate at the middle, the 

 surface remotely, irregularly and rather strongly punctured, the 

 sides with a more or less deep fovea, scutellum hanger than broad; 

 elytra pointed posteriorly, the shoulders prominent and angulate, 

 sti'ongly punctured in irregular double rows, the interspaces longi- 

 tudinally costate, the costae at the sides and at the apex very strongly 

 raised ; below impunctate, shining, legs long and slender, prosternum 

 oblong, its base modei'ately bilobed. 



Hab. Venezuela. 



This species, distinguished by its uniform fulvous colour 

 and the strongly costate elytra, was named by Lefevre 

 0. Jacobyi but not described. I have therefore renamed 

 it; the female is broader and larger, the thorax is, as 

 usual, more transversely shaped and more sparingly 

 punctured, and the elytral costse are more strongly raised 

 and their interstices at the sides rugose.
