1 Zygoliaris nitens Lee. — Proc. Am. Phil. Soc, XV, p. 318. 



Robust, rhomboidal, moderately convex, strongly shining, black, 

 the legs slightly piceous ; integuments subglabrous, the vestiture 

 white, consisting of very minute and sparse setiform squamules, 

 with large white scales remotely dispersed but more condensed at 

 the base of the second elytral interval, more distinct but sparse 

 beneath. Beak long and slender, evenly, strongly arcuate, slightly 

 tumid at base with the constriction distinct, feebly compressed and 

 densely punctured at the sides, especially behind the antennae, two- 

 fifths as long as the body in the male and two-thirds in the female, 

 smoother and less punctate in the latter sex ; antennas inserted at 

 basal two-fifths in the female or a little behind the middle in the 

 male, the scape nearly attaining the eyes, the scrobes almost com- 

 pletely inferior, basal joint of the funicle not quite as long as the 

 next four, the second one-half longer than the third ; club moderate, 

 elongate-oval, densely pubescent, with the basal joint composing 

 about one-third of the mass. Prothorax conical, one-half to two- 

 thirds wider than long, the sides feebly, evenly arcuate ; constric- 

 tion rather strong ; disk very coarsely, deeply, moderately closely 

 punctate, without trace of impunctate line. Scutellum small, oblong, 

 glabrous. Elytra at base much wider than the prothorax, rather 

 more than twice as long as the latter, parabolic in outline, the 

 humeral callus not laterally prominent; disk with very fine strige, 

 which are widely and deeply impressed and coarsely, not closely 

 punctate, the intervals convex, each with a single series of coarse 

 deep remote punctures, about as large as those of the striae but more 

 than twice as distant. Length 2.6-3.7 mm.; width 1.4-2.0 mm. 



Southern Florida. A distinct and easily recognizable species. 



CATAPASTUS u. gen. 



This genus contains some of the smallest centrinides thus far 

 discovered, and is rather isolated. Its nearest relative is probably 

 Zygobaris, but the divergence from even this form, which is itself 

 a strongly specialized type, is very notable. 



The beak is short, stout, broad, flattened toward apex, very 

 densely but finely punctate throughout, squamose and without 

 trace of basal constriction. The antenn* are inserted distinctly 

 beyond the middle, which contrasts greatly with their position in 

 Z3^gobaris, the scape nearly a<ttaining the eye, the basal joint of the
