moderate, stout, oval, densely pubescent. Prothorax short, three-fourths wider 

 than long, the sides broadly arcuate, becoming nearly parallel toward base, 

 strongly convergent, broadly and just visibly sinuate near the apex, the latter 

 truncate and not quite one-half as wide as the base, which is straight and 

 transverse, the median lobe one-fourth of the total width, prominent and 

 sinuato-truncate at apex ; disk somewhat coarsely, deeply, densely punctate, 

 the punctures tending slightly to coalesce longitudinally, the impunctate line 

 narrow but almost entire. Scutellum rather large, transverse, very densely 

 and conspicuously albido-squamose. Elytra but little wider and about four- 

 fifths longer than the prothorax, scarcely longer than wide, hemi-elliptical, 

 the humeri slightly oblique to the base of the prothorax, feebly tumid and but 

 slightly prominent ; disk deeply but not very coarsely striate, the intervals 

 flat, from two to three times as wide as the grooves and all deeply, densely 

 and confusedly punctate. Abdomen densely squamose. Prosternum flat, with 

 a transverse nude excavation near the apical margin, the coxae separated by 

 three-fifths of their own width. Length 3.2 mm. ; width 1.65 mm. 



Florida. 



In its longer, polished and almost impunctate beak, more elongate 

 second funicular joint and rather more widely distant anterior coxae, 

 as well as in its shorter and broader bodily form, this species is de- 

 cidedly aberrant ; but all the remaining characters seem to coincide 

 with those of the present genus. The single specimen appears to 

 be a female, and, in the other sex, the beak is very likely shorter 

 and more punctate as in the group of Centrinus containing denti- 

 cornis, to which the species of Nicentrus bear some analogy in 

 other respects also.

Rather stout, oblong-oval, convex, moderately shining, black, the 

 legs rufous ; vestiture whitish, consisting of long slender squamules, 

 moderately densely and evenly distributed, a little broader and closer 

 on the under surface. Beak in the male stout, becoming very thick 

 toward base, moderately arcuate, scarcely longer than the prothorax, 

 coarsely, deeply but not very densely, lineately punctate and grooved, 

 the antennae inserted distinctly beyond the middle, the basal joint of 

 the funicle longer than the next two, the second three-fifths as long 

 as the first and as long as the succeeding two, three to seven nearly 

 equal and subquadrate ; club small, rather narrowly oval. Prothorax 

 very nearly as long as wide, the sides parallel and feebly arcuate in 

 basal two-thirds, then broadly rounded and convergent to the apex, 

 which is distinctly less than one-half as wide as the base, apical con-
