glabrous, the small fine squamules very sparse throughout. Head minutely, 

 sparsely punctate, the transverse impression feeble ; beak slender, feebly, 

 evenly arcuate, evenly cylindrical, smooth, polished, finely, sparsely lineato- 

 punctate, confusedly so near the base, equal in length to the prothorax, the 

 antennae inserted just behind the middle, slender, the first funicular joint 

 fully as long as the next two. the second twice as long as wide and one-half 

 longer than the third, club rather narrow, oval, as long as the preceding four 

 joints combined. Prothorax nearly as long as wide, the sides nearly parallel 

 and straight in basal two thirds, then gradually broadly, evenly arcuate and 

 convergent to the apex, the subapical constriction feeble; apex truncate, 

 distinctly more than one-half as wide -as the base, the median lobe of the 

 latter feebly rounded; disk finely, sparsely punctate, the impunctate line dis- 

 tinct. Scutellum small, subquadrate, slightly broader behind. Elytra but 

 little wider than the prothorax, fully twice as long as the latter, parallel, 

 evenly rounded in apical third ; humeri scarcely at all prominent ; disk with 

 fine abrupt rather deep and even striae, the intervals flat, fully three times as 

 wide as the grooves, each with a single series of fine, feeble, rather distant 

 punctures, confused toward the base of the third. Abdomen finely, sparsely 

 punctured, but, as usual, densely so toward apex. Prosternum fiat, with a 

 small subapical pit, the coxae separated by one-half of their own width. 

 Length 3.5 mm. ; width 1.4 mm.

Not closely allied to any other species known to me, and repre- 

 sented by a single specimen which is undoubtedly the female, although 

 the abdomen has a small feeble subbasal impression, and the fifth 

 segment a small rounded indentation. A specimen in my cabinet 

 from Florida also belongs apparently to this species, but is larger 

 and with a much longer beak.

Slender, parallel, convex, shining, subglabrous, the dorsal setiform 

 squamules very minute but longer and more visible toward the 

 sides of the prothorax. Beak feebly, evenly arcuate, slender, cylin- 

 drical, as long as the prothorax in both sexes, a little thicker and 

 much more densely punctate in the male, the transverse basal con- 

 striction almost obsolete ; antennae inserted at the middle in the 

 male, or far behind this point in the female, the first funicular joint 

 as long as the next three, second one-half longer than the third ; 

 club moderate, as long as the four preceding joints combined. Pro- 

 thorax slightly but distinctly wider than long ; the sides parallel,
