250 RHYNCHOPHORA. 
Hab. Guaremata, Zapote, San Gerdnimo (Champion); Nicaragua, Managua (coll. 
Solari). | 
Two males and three females. A minute, rhomboid-ovate, shining black, almost 
glabrous form, with a coarsely punctured, convex prothorax, and subtriangular, 
punctate-striate elytra, the anterior tibiz with a long apical hook in the male, 
CHATOBARIS, gen. nov. 
Rostrum arcuate, cylindrical, very stout ; mandibles short, toothed on their inner edge; antennal club ovate, 
the funiculus slender ; prothorax tubulate in front, deeply bisinuate at the base; scutellum transversely 
quadrate, flat, free; elytra subtriangular; pygidium not visible ; prosternum unarmed, with a broad, 
smooth, shallow sulcus extending down its entire length, the sulcus limited on each before and between 
the coxee by an acute ridge, the coxe separated by about their own width; mesosternum exposed ; legs 
very short; femora feebly clavate, unarmed; tibize strongly unguiculate; tarsal claws divergent ; body 
broad, short-ovate, polished, setose. 
Type, Ch. nigrosetosus. 
This genus is related to Rhianus. It is one of the few Central-American Barids 
with conspicuously setose upper surface and legs. | 
1. Chetobaris nigrosetosus, sp.n. (Tab. XIV. figg. 6, 6a, 2.) 
Shining, black, the antenne ferruginous at the base; the upper surface clothed with scattered, long, erect, 
fine, blackish sete, the under surface with cinereous hairs, the legs setose. Head transversely 
depressed between the eyes, closely punctate above; rostrum about as long as the prothorax, sparsely 
punctate, the antenne inserted behind the middle. Prothorax broad, transverse, much rounded at the 
sides anteriorly, the short anterior lobe narrow, very sparsely punctate. Elytra about twice as long as, 
and a little wider than, the prothorax, conjointly rounded at the apex, the humeri oblique and rather 
prominent; sharply striate, the strie distinctly punctate, the interstices broad, flat, uniseriate-punctate. 
Beneath and the legs sparsely punctate, the prosternum with the depressed median space smooth i 
shining throughout ; first ventral segment excavate down the middle in the ¢. 
Length 33-32, breadth 23-21 millim. (¢ 2.) 
Hab. Panama, Caldera in Chiriqui 1200 feet (Champion). 
Three specimens. In this insect the scattered punctures on the prothorax and 
elytral interstices each bear a long, erect, fine, blackish seta. 
ELLIPTOBARIS, gen. nov. 
Rostrum arcuate, abruptly separated from the head above; mandibles slightly notched within, not decussate ; 
antennal club ovate, the funiculus widening outwards; prothorax tubulate in front; scutellum small, 
free ; elytra somewhat oval, the humeri oblique, not prominent, and forming an almost continuous 
outline with the sides of the prothorax; pygidium not visible; prosternum unarmed, with a broad, 
shallow, flattened sulcus, extending backward between the coxe, and limited on each side by an oblique 
ridge ; legs short ; femora unarmed, sulcate at the apex only beneath; tarsal claws free; body elliptic or 
rhomboid- elliptic, polished, clothed with a few scattered setiform scales, 
Type, H. setulosus. 
This genus includes two closely allied forms from Panama, both of which have 
deeply sulcate elytra, with the humeri not at all prominent and almost in a line with 
the sides of the prothorax. Elliptobaris approaches Chetobaris, but it has more the 
facies of the N.-American Jdiostethus tubulatus.
