Brazilian Baring 393 



than in the female, less arcuate and less tapering distally; it is 

 cylindric and finely, sparsely punctate in both sexes, and is separated 

 from the head by a very feeble impression. The mandibles are 

 small, bifid and decussate and the antennae post-medial, the funicle 

 much longer and more slender than in the preceding genus. The 

 prosternum is flat and separates the coxae by distinctly more than 

 their own width. The first ventral suture is extremely fine and 

 feeble, the second segment barely longer than the third or fourth 

 and very much shorter than the first. The two species at hand 

 have the beak much shorter and the elytral grooves very much less 

 punctate than in the Panama species identified as curtula by Cham- 

 pion, and they may be described as follows: 



Body stout, ovoidal, somewhat attenuate behind, convex, glabrous, shining and 

 black throughout; beak (c?) distinctly shorter than the prothorax, evenly 

 and distinctly arcuate and only very feebly and gradually tapering distally, 

 or ( 9 ) slightly longer, more arcuate or rather more bent medially, and 

 thence more rapidly tapering, shining in both sexes, the antennae blackish, 

 the club gradually formed; prothorax large, barely two-fifths wider than 

 long, the sides very feebly converging and just visibly arcuate, rather rapidly, 

 evenly rounding anteriorly to the very short and gradually and feebly 

 subtubulate truncate apex, which is much less than half as wide as the base, 

 rather coarsely but loosely punctate, longitudinally rugose at the sides, the 

 punctures gradually less coarse and sparser medially, the smooth line feebly 

 defined and not entire; elytra parabolic, only about a fifth longer than wide, 

 barely visibly wider than the prothorax and three-fifths longer; grooves 

 coarse and strongly punctate laterally, narrower and less punctate internally, 

 a third or fourth as wide as the intervals, which are somewhat strongly but 

 unequally punctate; pygidium small, vertical, densely punctate and sub- 

 similar in the sexes; abdomen without sexual modification. Length 3.0- 

 3.2 mm.; width 1.6-1.8 mm. Brazil (Chapada). May. Seven specimens. 



pinguicula n. sp. 



Body smaller and still more abbreviated, convex, polished, deep black; beak 

 (o 71 ) nearly as in the preceding but subequal in length to the prothorax, 

 which is much shorter, fully one-half wider than long, the sides strongly 

 arcuate, gradually less so and parallel posteriorly, the apex even less subtubu- 

 late, in fact not tubulate and nearly half as wide as the base; punctures strong, 

 forming rather less coarse, loose longitudinal rugae at the sides, well defined 

 and rather strong but sparse medially, the smooth line subentire; elytra 

 still shorter, only a little longer than wide, the similarly oblique sides nearly 

 straight, rather obtusely rounding at apex, at the feebly tumid humeri only 

 just visibly wider than the prothorax, two-thirds longer; grooves narrower 

 and much less punctate, the interstitial punctures distinct, more transverse 

 in certain lights. Length 2.6 mm.; width 1.28 mm. Brazil (Chapada). 

 May. One male specimen chapadana n. sp. 



The under surface of the body in all the known species is very 

 coarsely, closely and conspicuously punctured. 



Madarellus Csy. 



This is a rather large genus, distributed from the subarctic to 

 subantarctic regions in the American continents, but apparently
