elongate and very feeble impression ; it is however a female, as is 

 conclusively shown by the polished, almost impunctate beak ; the 

 impression is spurious, and has very nearly misled me in several 

 species of genera allied to this. There are but two examples known 

 to me, and the Florida specimen in my cabinet is a male, a little 

 larger than the Texas type, intense black throughout, the beak 

 short, rather thick, cylindrical, densely, deeply lineato-punctate, 

 evenly, feebly arcuate and distinctly shorter than the prothorax, the 

 antenna? being inserted at apical two-fifths; otherwise the two 

 specimens seem to agree very well indeed, except that the male 

 is a little stouter and with less elongate elytra, rather the reverse 

 of what might be expected.

(Ceiitiinus). 



Elongate-oval, convex, black, polished, the pronotum slightly 

 alutaceous, subglabrous, the vestiture consisting of minute slender 

 white squamules, very sparse throughout. Beak in the male scarcely 

 as long as the prothorax, thick, densely punctate, evenly cylindrical 

 throughout, compressed and carinate above, the frontal constriction 

 obsolete but represented by a large deep and transversely angulate 

 fovea ; antennas inserted at the middle, the second funicular joint 

 nearly as long as the first and as long as the next two ; club mode- 

 rately stout, elongate-oval, densely pubescent, as long as the four 

 preceding joints combined, and with the basal joint constituting 

 two-fifths of the mass. Prothorax not quite as long as wide, feebly 

 subconical, the sides more strongly arcuate before the middle, the 

 apex two-thirds as wide as the base ; punctures rather uneven in 

 distribution but generally not very close ; median line distinct. 

 Elytra but little wider than the prothorax and much more than 

 twice as long, the strife fine, abrupt; intervals wide, finely, feebly, 

 rather sparsely and transversely punctate, the punctures confused 

 on the third, but more or less evenly uniseriate on the others. Pro- 

 sternum broadly sinuate at apex, strongly, transversely constricted 

 behind the apex, broadly, feebly impressed along the middle, sepa- 

 rating the coxae by one-half their own width. Length 4.2-4. T mm. ; 

 width 1.7-1.9 mm. 



Indiana and Illinois. In the female the beak is very slender, 

 evenly but extremely feebly arcuate and fully one-half longer than 

 the prothorax, the prosternum flat. In three of the four males
