nent ; sides strongly convergent, the apex rather narrowly rounded in the 

 male, more broadly in the female, the striae very abrupt, deep, punctate, not 

 very coarse, tlie intervals flat, two to three times as wide as the grooves, 

 moderately coarsely, evenly, confusedly and very deeply punctured through- 

 out. Presternum in the male broadly, distinctly impressed along the middle, 

 with a small transversely impressed fovea behind tlie apex, the coxre sepa- 

 rated by scarcely two-fifths of their own width, almost similar in the female. 

 Length 5.3-6.0 mm.; width 2.8-3.2 mm. 



North Carolina ; Kansas. 



The beak in the male is feebly arcuate and much more strongly 

 so toward base ; in the female it is scarcely at all longer but more 

 slender, cylindrical, smooth and minutely, sparsely punctured, ex- 

 cept just before the eyes, where the punctures become coarse and 

 close, but not rugose, the antennae inserted just beyond the middle ; 

 in the female the antennae are more slender and with a smaller sim- 

 ple club. This is probably our largest centrinide. 



27 CeiltrinUS saletorosus n. sp. — Oblong-oval, the upper surface 

 moderately convex, black and dull, the legs and antennse more or less pice- 

 ous ; vestiture whitish, consisting of large broad and very dense scales 

 beneath, finer but extremely variable on the upper surface. Head rather 

 strongly and closely punctured, the transverse impression almost obsolete, 

 with a small deep median fovea, the beak in the male moderate in length and 

 thickness, as long as the head and prothorax, distinctly, evenly arcuate but 

 more abruptly bent at base, flattened toward apex and slightly compressed at 

 the sides, densely punctato-rugulose and deeply furrowed on the flanks, the 

 antennae inserted at apical two-fifths, rather slender, the club rather small, 

 oval, gradually pointed, densely pubescent, the basal joint composing rather 

 more than one-third of the mass, with a small smooth glabrous area on tlie 

 inner side toward base, at the centre of which there is a more or less distinct 

 dentiform process. Prothorax about two-fifths wider than long ; sides broadly 

 arcuate, convergent anteriorly, becoming almost parallel in basal two-thirds, 

 the constriction obsolete ; apex very nearly one-half as wide as the base, the 

 latter straight and transverse, the median lobe abrupt and densely^ coarsely 

 squamose; disk devoid of impunctate line, the punctures not very small, deej) 

 and rather dense throughout. Scutellum densely squamose. £'/^<)-« distinctly 

 wider, and from three-fourths to four-fifths longer than the prothorax, the 

 humeri rather large and abruptly, obtusely prominent ; sides behind them 

 unusually feebly convergent, the apex not narrowly rounded ; disk with 

 deep, abrupt, not very coarse grooves, the intervals two to three times as wide 

 as the grooves, densely, confusedly punctate, the punctures coarse but in- 

 distinct and polygonally distorted. Presternum not distinctly impressed, 

 separating the coxae by barely one-lialf of their own width, and with a deep 

 transverse groove behind tlie apical margin. Length 2.9-4.7 mm. ; width 

 1.3-2.2 mm.
