2oo MEMOIRS ON THE COLEOPTERA. 



throughout have widely spaced, long stiff erect setse; on the pro- 

 thorax they are about four in number at each side. 



Palaminus tegulatus n. sp. Moderately stout and convex, testaceous, the 

 elytra more flavate, broadly piceous on the suture from the base to about 

 apical fifth, the abdomen dark rufo-piceous; head and prothorax strongly 

 but not closely punctate, the former distinctly the wider, the last antennal 

 joint much wider than the tenth and, including the long terminal process, 

 about twice as long; prothorax convex, about a third wider than long, the 

 sides strongly converging from apex to base and strongly arcuate; elytra 

 two-fifths wider than the prothorax and twice as long, much longer than wide, 

 coarsely and rather closely punctate; female with the sixth ventral finely 

 and reticularly sculptured, the broad apex broadly sinuate in an evenly 

 rounded parabolic arc, which is seven or eight times as wide as deep; male 

 not at hand. Length (contracted) 3.2 mm.; width 0.5 mm. Nicaragua 

 (San Marcos), Baker. 



Allied to vittatus Shp., but with much longer elytra; the fuscous 

 sutural vitta is not quite as wide as a single elytron; the sides of 

 the body do not have the long bristling setae of the preceding species. 



Palaminus signifer n. sp. More parallel, convex, rather stout, piceous- 

 black, the legs pale flavate, the elytra each with a broad rufescent streak at 

 each side from the humerus to behind the middle; sides throughout with 

 widely spaced erect setae; head coarsely, rather closely punctate, scarcely 

 perceptibly wider than the prothorax, which is large and convex, fully a 

 third wider than long, coarsely, closely punctate, with the fine smooth median 

 line somewhat elevated basally, the sides but very feebly converging from 

 apex to base and broadly, moderately arcuate; elytra about a fourth or fifth 

 wider than the prothorax and three-fourths longer, about as long as wide, 

 broadening somewhat apically, less coarsely but somewhat densely punctate; 

 vestiture stiff, rather long and conspicuous; female with the sixth ventral 

 very broadly sinuato-truncate at tip. Length (contracted) 3.4 mm.; width 

 0.65 mm. Nicaragua (San Marcos), Baker. 



This species is allied to humeralis Shp., but has no lateral de- 

 pressions of the pronotum and no obvious paler elytral margin. 



Palaminus tortilis n. sp. Larger, convex, uniformly blackish-piceous in 

 color, the abdomen nearly black, the legs and antenna? pale flavate, the latter 

 slender, the last joint not much wider than the preceding, enlarged slightly 

 near its apex and between three and four times as long as the tenth, much 

 longer than the three preceding combined; head large, convex, slightly wider 

 than the prothorax, very finely, remotely punctate; prothorax large, convex, 

 nearly one-half wider than long, the sides parallel and feebly arcuate anteriorly 

 becoming gradually strongly arcuate and converging basally, the punctures 

 coarse but sparse; elytra large, only a little wider than the prothorax and 

 fully twice as long, much longer than wide, strongly but not very coarsely, 

 rather closely punctate; male with the ligula of the sixth ventral long, its
