41 Baris aerea Boh. — Sch, Cure, VIII, i. p. 141 (Baridius). 



This species is one of the smallest of the genus, of moderately 

 stout convex form, and is always highly polished and quite strongly 

 seneous in lustre. The beak is short, robust, feebly arcuate and 

 about two-thirds as long as the prothorax, the latter rather trans- 

 verse, from one-third to two-fifths wider than long, and with the 

 punctures very sparse, somewhat fine, moderately deep and sepa- 

 rated by from two to three times their own diameters, without 

 median impunctate line. The scutellum is small, flat and almost 

 circular. The elytra are not quite twice as long as the prothorax, 

 rather distinctly narrowed behind the humeri, with fine but deep 

 and abrupt, minutely punctulate grooves, the intervals wide, flat, 

 and each with a single series of very minute, remote punctures, not 

 confused on the second or third. Length 2.3-2.9 mm.; width 

 1.1-1.4 mm. 



This series of fifteen or more specimens before me is from Louisi- 

 ana and Texas. 



42 Baris scintillans n. sp. — Oval, moderately convex, black, tlie 

 legs slightly piceoiis ; integuments very smooth, brightly polished and with a 

 strong seneous metallic lustre. Head obsoletely, the beak finely and very 

 sparsely punctured, the latter ratlier robust, evenly and moderately arcuate, 

 not distinctly shorter than the prothorax ; antennse normal. Prothorax rather 

 short and transverse, two-fifths wider than long ; sides subparallel and just 

 visibly arcuate to apical third, then strongly rounded, thence strongly con- 

 vergent and distinctly sinuate to the apex, the latter very feebly arcuate, one- 

 half as wide as the base, the latter about two and one-third times as wide as 

 the head, transverse, the median lobe rather wide and distinct, rounded ; disk 

 without median line, the punctures fine but deep, sparse, about one-half as 

 wide as the scutellum and separated by two to three times their own diameters, 

 almost completely obsolete in apical fifth. Scutellum very small, nearly cir- 

 cular. Elytra scarcely more than one-fourth longer than wide, a little more 

 than twice as long as the prothorax, and, at basal third, very distinctly wider 

 than the latter ; sides parallel and feebly arcuate, the liumeri feebly tumid, 

 not at all prominent laterally ; apex broadly, almost semi-circularly rounded ; 

 disk very finely but deeply and abruptly striate, the strise not visibly punc- 

 tate ; intervals wide, flat, three to four times as wide as the strife, each with a 

 single series of excessively minute, feeble, remote punctures, which are only 

 observable under special conditions of amplification and illumination ; set<e 

 not observable under moderate power. Abdomen finely, sparsely punctate, the 

 metasternum quite coarsely, deeply and densely so. Anterior coxae rather 

 widely separated. Length 2.2 mm. ; width 1.0 mm.
