preceding joints combined. Prothorax one-third wider than long, the sides 

 feebly convergent, broadly, evenly and feebly arcuate nearly to the apex, tben 

 gradually more strongly convergent, but not at all sinuate, to the apex, the 

 latter truncate and one-half as wide as the base, which is straight and trans- 

 verse, the lobe rather small but distinctly prominent ; disk with deep and 

 moderately large punctures, which are perforate and rather widely separated, 

 but somewhat unevenly distributed, the impunctate line narrow but distinct, 

 even and entire. Scutellum very densely squamose. Elytra slightly wider than 

 the prothorax and about four-fifths longer, the sides quite strongly convergent 

 throughout, the apex somewhat narrowly rounded ; disk rather coarsely, 

 deeply striate, the intervals from one-half to once wider than the grooves, 

 closely, deeply, confusedly and somewhat coarsely punctured throughout. 

 Abdomen densely squamose. Prosternum perfectly flat, separating the rather 

 large coxa? by one-fifth of their own width. Length 3.8^4.0 mm. ; width 1.7— 

 1.8 mm.

This species is not closely allied to any other, although belonging 

 in the neighborhood of decipiens ; it differs in its much more abbre- 

 viated basal joint of the antennal funicle and very markedly in the 

 nature of the pronotal sculpture and vestiture. The type is a 

 female ; in the male the beak is a little shorter and thicker, with 

 the antennas inserted at apical two-fifths. Three specimens. 



3 NicentrilS SCitlllllS n. sp. — Elongate-oval, convex, black and shining 

 throughout, the legs somewhat piceous ; vestiture white, consisting of large 

 dense scales beneath and narrower sparsely placed squamules above, the 

 latter more evident toward the sides of the pronotum but not forming a defi- 

 nite vitta, not denser along the median line ; on the elytra they form a single 

 or partially double line on each interval. Head finely but deeply, rather 

 closely punctured, not squamose, the impression entirely obsolete ; beak 

 moderately thick, rather feebly, evenly arcuate, coarsely, deeply, linearly 

 punctate throughout at the sides and longitudinally furrowed, nearly as long 

 as the head and prothorax, the antennae inserted near apical two-fifths, the 

 scape rather long but not attaining the eye, the basal joint of the funicle as 

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

 rather small, oval, densely pubescent, about as long as the preceding four 

 joints combined. Prothorax very nearly as long as wide, the sides broadly, 

 evenly, feebly arcuate and convergent anteriorly, becoming nearly parallel in 

 basal two-thirds, the apical constriction completely obsolete ; apex truncate, 

 fully one-half as wide as the base, the latter transverse and straight, the 

 median lobe one-third the total width, prominent ; disk without distinct 

 median line, the punctures coarse, not very deep and partially coalescent, 

 forming longitudinal rugae. Scutellum quadrate, squamose, the apical angles 

 acute and prominent. Elytra a little wider than the prothorax and almost 

 twice as long, the humeri small but decidedly prominent, the sides behind 

 them evenly and sensibly convergent, the apex rather abruptly but not
