Epicaerus (Epicaerus) concolor Sharp 1891

Hab.MEXICO, Las Vigas (Höge).

Niger, opacus, brevissime setosus; prothorace fortiter profunde rugoso-punctato; elytris seriebus punctorum minus remotorum.
 
Long. 9½—10 millim.

This is one of the species that, though covered with scales, still appears quite black. It is closely allied to E. tristis, but is readily distinguished by the much smaller, more numerous punctures in the series of the elytra. The rostrum is deeply sulcate along the middle in the male, more broadly and less deeply so in the female; the lateral impressions are elongate and distinct; and there is a rather large fovea between the eyes. Thorax elongate, very coarsely and deeply punctate, a little flattened and impressed along the middle in the male, but scarcely at all so in the female. Elytra quite dull, furnished with very regular series of rather fine punctures, with a short minute serial setosity on the interstices.
 
Five specimens have been obtained of this species. There is a good deal of difference between the sexes, the female being a much broader and more obese insect than the male and having the apical portion of the elytra more elongate and perpendicular.
