450 RHYNCHOPHORA. 
narrow on the disc, feebly costate at the apex, each with a row of scattered moderately coarse punctures. 
Beneath very coarsely, the abdomen and middle of the metasternum sparsely and finely, punctate ; first 
ventral segment slightly hollowed down the centre in the ¢. Prosternum (fig. 33 6) very deeply sulcate to 
near the coxee and hollowed thence to the base, the sulcus smooth and sharply margined, the basal process 
emarginate behind and extending angularly forwards for a short distance in front. Femora unarmed. 
Length 23-23, breadth 1-14 millim. (¢ 9.) 
Hab. Nicaracva, Managua (Solari). 
Seven specimens. Extremely like P. puncticollis (Boh.*), the type of which I have 
seen, but with the basal portion of the prosternum formed very much as in P. diversa 
(e.g. with a short, angular projection between the coxe in front), the elytra not so 
broadly striate, &c. The rounded apices of the elytra and the gibbous rostrum distin- 
guish P. abrupta from P. diversa, and the structure of the prosternum, rostrum, &c¢., 
separates it from P. dividua. 
51. Pseudobaris diversa, sp. n. 
Oblong-ovate, dull, black, with a brassy lustre, glabrous above, the punctures on the under surface and legs 
each bearing a minute scale. Head minutely punctate, alutaceous, transversely depressed between the 
eyes ; rostrum (¢) arcuate, stout, about as long as the head and prothorax, shining, closely strigoso- 
punctate, (2) smoother, longer, and more slender, the antenne inserted at (¢) or behind (Q ) the 
middle. Prothorax transverse, gradually and arcuately narrowing from the base, feebly constricted in 
front; closely, coarsely punctate, except along the median line, the interspaces alutaceous. Elytra 
gradually narrowing from the rounded humeri, depressed along the suture, each with a short angular 
prominence at the apex; deeply punctate-striate, the interstices subcostate on the apical declivity, each 
with a series of shallow transverse impressions. Beneath coarsely, the abdomen finely, punctate; first 
ventral segment slightly depressed down the middle. Prosternum deeply sulcate from the apex to 
between the anterior coxe, the sulcus sharply margined at the sides anteriorly and strongly bifurcate 
posteriorly, the basal process depressed along the middle, angularly extended forwards, aud emarginate 
behind. Femora unarmed. 
Length 23-33, breadth 1-14 millim. (¢ @.) 
Hab. GuatemMata, Guatemala city (Salvin, Champion), Zapote, Capetillo, Duefias 
(Champion); Costa Rica, Escazu (Biolley); Panama, Volcan de Chiriqui (Champion). 
Found in numbers in Guatemala. This insect superficially resembles P. crzbrella, but 
it has the apices of the elytra angularly produced as in P. ca/lostpennis, differing from 
both of them in the strongly bifurcate prosternal sulcus and the dull alutaceous surface 
of the prothorax. P. subenea (Kirsch), from Peru, is an allied form with the prosternal 
sulcus less furcate behind, the rostrum shorter, the prothorax finely punctured, &c. 
CERCOBARIS, gen. nov. 
fandibles short, decussate ; rostrum strongly and abruptly curved from the base, very stout and compressed, 
not longer than the head and prothorax, the antenne inserted just behind the middle, the antennal club 
densely pubescent, oblong-ovate, and about as long as joints 2-7 of the funiculus; prothorax feebly 
constricted in front; scutellum free, rounded or oblong; elytra oblong or subtriangular, a little wider 
+ Baris sulcipennis, Bris., is not synonymous with this species as stated by v. Heyden (Deutsche ent. 
Zeitschr. 1882, p. 156), but is a true Baris, sensu Casey: cf. wnfra, p. 460.
