COLEOPTERA. 185 



tlie eyes straight and rapidly convergent anteriorly ; supra-antennal ridges 

 Hat above, transverse anteriorly and disappearing in the general surface of the 

 clypeus which is declivous anteriorly, produced, and vt;ry strongly rounded 

 at the apex, almost angulate ; eyes flat, rather large, having just within 

 each on the front a very fine carina ; interoeular surface feebly convex, 

 broadly impressed on each side witliin the antennal ridges, very deeply 

 densely, and slightly unevenly punctate, punctures round, rather more 

 sparse along the middle, and much smaller on the epistoma ; labrum trans- 

 verse, feebly sinuate anteriorly ; antennae slightly shorter than the pronotum, 

 outer joints strongly compressed, second joint nearly two-thirds as long as 

 the third, three to five decreasing in length, seven to ten slightly produced 

 outwardly at apex. Proihorax widest at the base where it is about two-fifths 

 wider than long ; sides very feebly arcuate, straight in the posterior half; 

 apex broadly eraarginate, about three-fourths as long as the base, angles 

 acute ; base strongly arcuate in the middle, sinuate in the middle of each 

 side, and thence straight and transverse to the basal angles which are right 

 and not at all rounded ; disk strongly convex, densely finely and coalesnently 

 punctate, punctures round, deep and somewhat scabrous toward the sides, 

 interspaces very minutely granulose. Elytra at base very slightly wider 

 than the pronotum, widest in the middle where they are about one-half 

 wider than the pronotum ; sides rather strongly arcuate, strongly convergent 

 and nearly straight to the apex which, conjointly, is somewhat obtuse but 

 scarcely rounded ; disk from above two and one-half times as hmg as the 

 pronotum, convex, strongly declivous toward the apex, finely feebly and 

 rather densely punctate, punctures almost uniformly distributed; striate, 

 striae scarcely perceptibly impressed and very slightly more densely punc- 

 tate, darker in color ; surface also confusedly creased. Under surface finely 

 punctate, the metasternum sparsely and more coarsely so, the abdomen very 

 densely ; prosternum and its side-pieces eqiTally strongly and confusedly 

 ruguloso-punctate. Legs slender ; anterior tibiae slightly prolonged exter- 

 nally at tip, terminal spurs almost exactly equal, long and stout ; first joint 

 of the corresponding tarsi slightly longer than the next two together; first 

 joint of the posterior much longer than the next two together and very 

 slightly shorter than the last ; claws very long and slender, perfectly simple. 

 Length 9.5 mm. ; width 4.2 mm.

Tlie description is taken from the female. There is a very narrow 

 median space toward the base wl)ich is very sparsely punctate, but 

 which is scarcely noticeable ; the anterior iangles are acute but not 

 produced, and the surface is very evenly convex througiiout ; in the 

 male the punctuation is less dense. I cannot identify it with any of 

 the species described in the Biologia Cent.-Amer.
