Baring 361 



Pseudobaris Lee. 



Additional material received since my revision of this genus, 

 together with more careful discrimination of that there utilized, 

 reveals the fact that our species of Pseudobaris are really very 

 numerous, and, as a rule, are smaller, narrower and more densely 

 sculptured than the abundant tropical species; they also, in general, 

 resemble each other very closely to superficial view, so that much 

 care should be taken in attempts to identify them from description. 

 It is to be regretted that they also seem to be less gregarious than 

 in Baris, Auloharis and some other genera, so that most of the 

 species are now represented only by single specimens. 



Before attempting to identify the species, care should be taken 

 to fix the status of two important specific landmarks, nigrina 

 Say and angusta Lee. These are both small or very moderate 

 species; the former, described from Pennsylvania, is said to be 

 a tenth of an inch long — that is 2.5 mm. — and to have a few scattered 

 white hair-like scales on the elytra; I have selected a New Jersey 

 specimen in my collection as being entirely typical; the range of 

 the species is from Rhode Island to Indiana, so far as my series 

 shows and the dimensions are 2.6-3.1 by i. 0-1.2 mm. The other 

 species, described originally as Baridius angustus, is still smaller 

 and especially more slender, my authentically typical representative 

 being 2.5 by 0.9 mm. in dimensions; it is distinguishable from others 

 that resemble it very closely and are always confused with it, by 

 the structure of the antennae, these having been insufficiently 

 studied in my former work; they are unusually short, the three 

 outer joints of the funicle transverse and the club rather small 

 and very briefly oval ; the prpthorax is cylindric and much narrower 

 than the elytra. The elytra have no scattered white hairs, as they 

 have in nigrina and some related species, and the sculpture of the 

 strial intervals has an imbricated appearance toward the sides. 



Pseudobaris porcina n. sp. — Broadly suboblong-oval, strongly convex, 

 shining, deep black throughout, the tibiae feebly rufescent; beak in the 

 male rather stout, feebly arcuate, closely punctate and as long as the 

 prothorax, which is a third wider than long, with the arcuate upper 

 profile very strongly declivous anteriorly; sides broadly arcuate, a little 

 more so apically and gradually almost parallel basally, the constriction 

 feeble; apex not quite half as wide as the base, which is gradually but 

 strongly lobed medially; punctures coarse and dense laterally, gradually
