beak, non-sulcate prosternum, more narrowly squamose elytral inter- 

 vals, subobsolete median line and finer punctures of the pronotum, 

 and in its smaller size. Three specimens. 



5 NiceiitrilS effetus n. sp. — Oblong-oval, moderately convex, black, 

 the legs red ; integuments rather smooth, moderately shining ; vestiture white, 

 consisting of slender sparse squamules on the pronotum, larger and a little closer 

 toward the sides and on the median line toward base ; on the elytra broader 

 and whiter but still narrow, disposed in a single almost even series on each 

 interval, sometimes partially double on the third, fifth and seventh toward 

 base ; scales of the under surface large but sparse on the abdomen, dense on 

 the met-episterna. Head finely, strongly, rather closely punctate, the beak 

 somewhat slender, cylindrical, smooth, finely seriato-punctate, more closely 

 so along the sides, about as long as the head and prothorax, rather strongly 

 arcuate in basal half but nearly straight thence to the apex ; antennae inserted 

 at the middle, the basal joint of the funicle as long as the next three, rather 

 stout, second but slightly elongate, club small. Prothorax fully one-third 

 wider than long, the sides parallel or feebly divergent from the base to apical 

 third and nearly straight, then broadly rounded and strongly convergent to 

 the apex, the constriction completely obsolete ; apex truncate, rather more 

 than one-half as wide as the base, the latter transverse, broadly, feebly bisinu- 

 ate, the median lobe small but somewhat prominent ; disk without trace of 

 impunctate line, the punctures small and distinctly separated. Scutellum 

 small, quadrate or rounded, very densely squamose. Elytra very slightly 

 wider than the prothorax and nearly twice as long, hemi-elliptical, the humeri 

 but slightly prominent ; disk deeply and abruptly striate, the intervals flat, 

 about twice as wide as the grooves, each with a tolerably even single series of 

 small deep punctures. Prosternum flat, separating the coxae by fully two- 

 fifths of their own width. Length 2.2 mm. ; width 0.85 mm. 



Florida (Haw Creek). 



The single specimen i$ a female and represents a species allied to 

 decipiens, but differing- in its much smaller size, longer elytra with 

 uniseriate intervals, and in many other characters. 



6 Nicentrus contractus n. sp. — Oblong-oval, convex, stout, black 

 and but feebly shining, the legs not paler ; vestiture consisting of whitish 

 scales, very fine, sparse and almost uniformly distributed on the pronotum, 

 broader, denser and widely confused on all the elytral intervals, and very 

 broad and dense throughout beneath. Head finely but deeply, somewhat 

 closely punctured, the impression almost completely obsolete and with a deep 

 median fovea ; beak long, rather slender, cylindrical, evenly, rather strongly 

 arcuate, polished and almost completely impunctate except at base, where 

 there are also a few squamules, and where the thickness becomes somewhat 

 greater, fully one-half as long as the body ; antennae inserted distinctly be- 

 yond the middle, the second funicular joint unusually elongate, more than 

 three-fourths as long as the first and nearly as long as the next three; club
