Show 626 MR. MARTIN JACOBY ON NEW [Nov. 6, minute punctures are visible, a narrow longitudinal stripe near the suture from the base to the apex, the extreme lateral margin joining the other stripe at the apex, flavous, these stripes are further connected by a very short transverse band near the apex which includes a spot of the ground-colour; elytral epipleurae black within, flavous at the outer edge; underside and legs black. Hab. Brazil. The many-spotted thorax, the opaque colour of the elytra, and the apical markings will separate this species from its allies. The name of (E. brunneicollis given to this species by Clark having no reference to it, I have altered it. EPIONYCHIS APVENA (Clk. Catal.). Entirely obscure testaceous, the head and thorax impunctate ; elytra closely punctured, with an obsolete longitudinal discoidal stripe not extending to the apex and another extremely faint stripe nearer the suture. Length 1| line. A very small species of unattractive appearance, obscure testaceous or fulvous, the head impunctate, the antennae fuscous, the lower three or four joints obscure fulvous; thorax rather more than twice as broad as long, the sides but slightly rounded, the anterior angles thickened but not produced, the surface with a rather distinct transverse sulcus near the base, impunctate or with a few very fine punctures; elytra very closely and rather strongly punctured, the shoulders prominent, the disc with an obscure piceous stripe not quite extending to the apex and a similar but scarcely perceptible stripe near the suture; epipleurae, underside, and legs coloured as above. Hab. Brazil, Rio Janeiro. Clark was uncertain as to the habitat of this species, but two specimens named by Clark and formerly contained in the Baly collection are labelled Rio Janeiro. EPIONYCHIS TURPIS (Clk. Catal.). Black, the sides of the thorax and the base of the femora flavous ; thorax nearly impunctate ; elytra extremely minutely punctured, flavous, the extreme apex black. Length 2 | lines. Head impunctate, the vertex shining, black, eyes large, frontal elevations transverse, strongly raised, carina acute, convex, the clypeus and the labrum flavous; antenna? rather slender, black, the lower three joints flavous below and partly above, third and fourth joints equal, the eleventh with a short appendage or twelfth joint; thorax three times broader than long, the sides very strongly rounded and flattened, tbe anterior angles not produced outward; the disc black, shining, very minutely punctured when seen under a strong lens, the sides, as far as the flattened portion, flavous |
