COLEOPTBRA, 
Baridiides. 
JJaridius quadratus, Lee., = transversus, Say ; 13. puhescens, Uhler, = 
Centrinus holosericeus, Gyll., = C. penicellus, Hbst. ; J. L. Leconte, 
P. Am. Phil. Soc. xv. pp. 291 & 308. 
The following new genera and species are described by Leconte, 1. c. : 
Orthoris^ p. 286. Baridides : — Facies of Orchestes. Pygidium oblique ; 
fifth ventral segment longer, rounded at tip ; outer joints of funiculus 
but little broader, club large, elongate-oval, pubescent. Rostrum long, 
slender, straight. For Orth, crotchi, ibid., California. 
JRhoptobaris, p. 287. Differs from Orthoris in its shorter, less slender, 
and curved rostrum. Facies of Tricholaris. R. canescens^ ibid., Colo- 
rado. 
TrichobariSf ibid., of elongate form, densely clothed, and with front 
coxee very narrowly separated. For Baridius trinotatus, Say, B. plumbeus, 
Lee., and T. texana, p. 288, Texas. 
Aulobaris^ p. 288. Differs from Baris proper by the more slender 
antennae, the second joint of the funiculus being quite as long as the 
first, &c. Yov Baridius scolopax, Say, B. ibis and nasutus (renamed naso)^ 
Lee., and B. anthracinus^ Boh. (subsequently transferred to Pseiidobaris, 
p. 419). 
OnychobariSf p. 294. Differs from Baris in the more oval, entirely 
sensitive and pubescent antennal club, of which the first joint forms less 
than half; the larger and divergent claws, &c. For Baridius densus, 
distans, and seriatus, Lee., and 0. subtonsa smd pectorosa, p. 296, cribrata, 
p. 296, Texas, rugicollis^ p. 297, Middle and Southern States. 
Pseudobaris, p. 297. Differs from Trichobaris in the widely separated 
front coxae and absence of dense scaling. Pov Baridius farctus, angustuSj 
(renamed angustula^ p. 420), and^^^s^7Z^^s, Lee., nigrinus, Say, and t-signum^ 
Boh. ; also P. albilatus, p. 298, and P. pectoralis, p. 420, Florida. Bari- 
dius anthracinus^ Boh., is transferred to this genus from Aulobaris^ 
p. 419. 
Ampeloglypter^ p. 299. Differs from Madams in the shorter and 
stouter rostrum, stouter antennae, broadly excavated prosternum, which 
is not suddenly declivous between the coxae, untoothed front femora, 
and claws connate at base. For Madams vitis, Riley, = Baridius sesos- 
tris, Lee., and A. ater (= M. ampclopsis^ Walsh & Riley, undescribed), 
S. and W. States, and crenatus, Virginia and Maryland, p. 300. 
PachybariSy p. 302. Centrini : characters of Onychobaris, except that 
the elytra are conjointly rounded behind, so as to cover the pygidium, 
and the fifth ventral segment, though very transverse, is broadly rounded 
behind. P.porosus, sp. n., ibid., Florida. 
Stethobaris, ibid. Differs from Pachybaris especially in the deep and 
sharply defined pectoral groove. For Baridius ovatus, Lee., == Campy - 
lorrhynchus tubulatus, Say, and S. corpulentus, p. 420, Florida.' 
Microcholus, p. 303. Differs from the two preceding genera in its 
slender ungrooved tibiae ; side margin of prothorax well defined ; form 
of Baris, but stouter and more convex, with a few scattered scales. For 
M. striatus said puncticolUs, Florida, and IwvicoUis, Missouri, p. 304.
