at the base of the pronotum at each side and a few before the scu- 

 tellum, also several widely dispersed on the elytra and a small 

 group at the base of the third interval ; under surface sparsely, the 

 legs, meso- and met-episterna and sides of the last three ventral 

 segments more or less densely, clothed with large white scales. 

 Head separated from the beak by a very feeble impression, the 

 beak fully as long as the prothorax, flattened near the apex and 

 strongly compressed toward base, strongly, evenly arcuate, sparsely, 

 very minutely punctate throughout and moderately stout; antenna 

 slender, the basal joint of the funicle slender, fully as long as the 

 next four, the second slender and as long as the next two, club 

 small, stout, densely pubescent, with the basal joint constituting 

 rather more than one-half the mass as in Oomorphidius. Pro- 

 thorax scarcely two-fifths wider than long, the sides broadly arc- 

 uate and gradually strongly convergent from the obtusely rounded 

 basal angles to the apex, the latter not tubulate, the constriction 

 very feeble ; base transverse, the median lobe wide but very feeble ; 

 disk finely, sparsely punctate. Scutellum well-developed, elongate- 

 oval and tumid. Elytra not at all wider than the prothorax, two- 

 thirds longer than the latter and about as long as wide, the striae 

 rather fine but deep, with the edges obtuse, the intervals wide, each 

 with a single somewhat uneven series of fine distant punctures. 

 Anterior coxee separated by rather less than one-third of their 

 width, the tarsal claws small, short, very thick but free and mode- 

 rately divergent. Length 4.5 mm. ; width 2.3 mm. 



Florida (Lake Harney). Cab. LeConte. Represented, as far as 

 known, by the unique type. The upper surface in the type is not 

 denuded of scales as supposed by LeConte ; the punctures, other 

 than those very remote ones which bear the long isolated scales, 

 bear each an infinitesimal seta.

Broadly oblong-oval, the elytra rapidly narrowed and sinuate at 

 the sides behind ; body and antennae black, smooth and shining, the 

 legs rufous ; under surface, legs and elytra covered rather densely 

 with large oval white scales, which, on the elytra, are a little closer 

 on the third and fifth intervals toward base and behind the middle ; 

 pronotum more sparsely covered with elongate squamules, except a
