ELLIPTOBARIS.—ACANTHOBARIS. 951 
1. Elliptobaris setulosus, sp. n. (Tab. XIV. figs. 7, 74, 3.) 
Elliptic, somewhat flattened above, shining, black, the tips of the tarsi ferruginous; the prothorax set with 
long, fine, scattered, pallid, erect sete, the elytral interstices each with a scattered line of coarser, 
semierect, yellowish-white sete; the under surface and legs very sparsely clothed with fine, hair-like, 
white scales. Head with a deep transverse groove between the eyes; rostrum moderately stout, slightly 
longer than the head and prothorax, punctate-striate, in the 2 a little longer and more sparsely punctate ; 
antenne with joint 2 of the funiculus as long as 3 and 4 united, the club ovate. Prothorax transverse, 
gradually narrowing from the base, strongly and abruptly constricted in front; closely (in the 2 more 
sparsely) punctate, except along a narrow space down the middle, the punctures becoming coarser 
towards the sides. Scutellum transverse, broadly truncate behind. Elytra considerably wider than the 
prothorax, rather long, the humeri not prominent; deeply sulcate, the sulci feebly punctate, the 
interstices somewhat convex, rather broad, each with a widely scattered series of coarse setigerous 
punctures and a few irregularly-distributed minute punctures between them. Beneath very sparsely, in 
the 3 more closely, punctate. Prosternal sulcus terminating in a transverse cavity in front, closely 
punctured between the coxe in the ¢, polished and very sharply defined in the Q. Anterior coxe 
separated by a little less than their own width. First ventral segment depressed down the middle 
in the g. 
Length 4-43, breadth 21-21 millim. (¢ @.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
One male and two females, 
2. Elliptobaris nudicollis, sp. n. 
Rhomboid-elliptic, somewhat flattened above, shining, black, the tips of the tarsi ferruginous; the elytral 
interstices each with a widely-scattered series of semierect pallid sete, the under surface and legs with 
scattered, minute, hair-like, white scales. Head with a deep transverse groove between the eyes; 
rostrum stout, strongly arcuate, not longer than the head and prothorax, sparsely punctate. Prothorax 
transverse, narrowing from the base, strongly and abruptly constricted in front ; sparsely, very finely 
punctate, the punctures becoming coarser at the sides, bare. Scutellum small, trapezoidal. Elytra 
moderately long, with the sides at the base forming an almost continuous outline with those of the 
prothorax ; deeply punctato-sulcate, the interstices towards the sides and apex convex and not wider 
than the strie, flatter and broader on the disc, sparsely, minutely punctate and with a widely scattered 
_ Series of coarser setigerous impressions. Beneath sparsely punctate. Prosternum as in Z, setulosus. 
_ Anterior coxe separated by fully their own width. 
Length 34-4, breadth 13-22 millim. (9 ?) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
_ Four specimens. A little less elongate than E. setulosus, the rostrum shorter, stouter, 
and more curved, the prothorax finely punctate and bare, the elytra more rounded at 
the sides and with fewer sete. 
ACANTHOBARIS, gen. nov. 
Rostrum (3) stout and areuate, ( 2 ) stout to about the basal third, with the apical portion longer, straighter, 
_ and more slender than in the ¢ ; mandibles short, blunt at the tip, rounded externally, straight on their 
inner edge when closed; antennal club short-ovate, the basal joint sparsely pilose ; prothorax tubulate in 
front, deeply bisinuate at the base; scutellum small, transverse, free; elytra triangular ; pygidium 
hidden ; prosternum unarmed, narrowly sulcate; anterior coxw separated by about one-third their own 
. width; legs stout ; femora unarmed, the intermediate and posterior pairs feebly suleate beneath ; all the 
- tibiee acutely dilated on their outer edge near the base and at the apex; tarsal claws very small, connate 
at the base ; body convex, rhomboidal, polished, almost bare above. ‘ 
Type, A. castuneipennis.
