448 RHYNCHOPHORA. 
( Townsend, in U.S. Nat. Mus.), Temax in N. Yucatan ( Gaumer) ; Nicaragua, Managua 
(Solari). 
Numerous examples. Smoother than P.. cribrella, the surface with an eneous 
lustre, the elytra with a series of very fine shallow punctures down each interstice, the 
apices (in the form selected as typical) very feebly and obtusely produced, the anterior 
femora unarmed. 
47. Pseudobarius scabrida, sp. n. 
Oblong-ovate, subopaque, black, the elytra and abdomen with a faint eneous lustre; glabrous above, the 
punctures on the under surface and legs each bearing a minute scale. Head densely punctate, trans- 
versely grooved between the eyes; rostrum strongly arcuate, very stout, nearly as long as the head and 
prothorax, densely punctate, smoother at the tip in the 2. Prothorax transverse, feebly constricted in 
front, the sides rounded anteriorly and parallel behind; coarsely, densely, confluently punctate. Elytra 
oblong, a little wider than the prothorax, very gradually narrowing from the base; deeply punctate- 
striate, the punctures becoming coarser towards the base, the interstices rather narrow, densely, 
transversely rugose, flat on the disc, convex at the apex, the ninth cariniform, almost parallel with the 
apical margin, and somewhat obtusely dentate at its point of termination near the suture. Beneath 
coarsely and densely, the shining ventral segments more finely and sparsely, punctate. Prosternal 
sulcus shallow. Legs short; femora and tibiz rugose, the femora unarmed. 
Length 2}-2,9,, breadth 1-11 millim. (¢ 92.) 
Hab. Mrxtco, Cuernavaca (Hége); GuatemaLa, San Gerdénimo (Champion). 
Three specimens. A small, oblong, very rugose form, with a strongly arcuate, stout 
rostrum, densely asperate elytral interstices, the ridge on the ninth terminating in a 
small prominence, short legs, and a shallow prosternal groove. The surface-sculpture 
is very like that of P. rugipennis (except that the elytral interstices are narrower), and 
the apices of the elytra are formed much as in P. acutipennis. 
48. Pseudobaris lucida, sp.n. (Tab. XXI. tigg. 30, 30a, 6, ¢; 31, 2.) 
Somewhat fusiform, flattened above, very shining, seneous or cupreo-eneous; the third elytral interstice with 
a small patch of whitish scales at the base, the punctures on the under surface and legs each bearing a 
small scale. Head closely punctate, transversely depressed between the eyes; rostrum (d ) about as 
long as the head and prothorax, arcuate, moderately stout, closely punctate at the base, becoming more 
slender, flattened, and smoother towards the tip, ( 2 ) a little longer and abruptly flattened and smoother 
from near the base, the antenne inserted slightly behind the middle in the ¢ and at the basal third in 
the 2. Prothorax broader than long, conical, feebly constricted in front ; closely, rather coarsely 
punctate, except along the smooth median line. Elytra very gradually narrowing from the oblique 
humeri, which are almost in a line with the sides of the prothorax, more or less undulate on the disc 
and depressed along the suture, the apices separately rounded; punctate-striate—the strie sinuous 
towards the apex and the punctures becoming coarse and conspicuous towards the base,—the interstices 
broad, flat, narrowly and sinuously costute posteriorly, each with a scattered row of minute punctures. 
Pygidium large and convex in the g, subhorizontal and almost hidden in repose in the 2. Beneath 
coarsely, the abdomen finely, punctate; fifth ventral segment truncato-emarginate at the apex (and the 
pygidium partly exposed ventrally) in the ¢, longer and ascending to the tip in the 2. Prosternal 
sulcus straight, shallow, incompletely margined. Legs rather slender ; femora unarmed. 
Length 3-33, breadth 1z~-13 millim. (¢ 2.)

Chiriqui 5600-4000 feet (Champion).
