than the prothorax, the apices angularly, horizontally produced; pygidium exposed, transverse, vertical ; 
prosternum shallowly (C. forttrosirts and C. parva) or deeply (C. brevicauda) sulcate, the basal process 
short and depressed (longitudinally ridged behind each coxa in (. brevicauda); anterior cox separated 
by not more than half their own width; femora sublinear, sulcate, unarmed ; tibiae unguiculate at the 
outer apical angle, and acute or toothed at the inner angle (fig. 345); tarsi with the third joint 
somewhat narrowly bilobed, the claws very short, small, subconnate at the base; body oblong or 
elongate, coarsely sculptured and almost bare above. 
Type, C. fortirostris. 
Two species from Central America are referred to this genus, and Baridius parvus, 
Kirsch, from Peru, also belongs here. Cercodbaris is nearly related to the N.-American 
Desmoglyptus, Casey, but differs from it in the form of the rostrum, antennal club, 
apices of the elytra, &c. All three forms have somewhat the facies of Pseudobaris 
angustula, Lec. ‘The produced apices of the elytra are suggestive of P. acutipennis 
and its allies, 
1. Cercobaris fortirostris, sp.n. (Tab. XXI. figg. 34, 34a, b, 3.) 
Elongate, narrow, somewhat scaphiform, subopaque above, black, with a faint neous tinge, almost glabrous. 
Head closely punctate, transversely grooved between the eyes ; rostrum exceedingly stout, about as long 
as the head and prothorax, closely, longitudinally, strigoso-punctate. Prothorax broader than long, 
rather convex, gradually narrowed from the middle; coarsely, densely punctate. Scutellum rounded, . 
rugose. Elytra oblong, transversely depressed on the disc at the base, the apices separately, horizontally 
produced ; narrowly punctate-striate, the punctures becoming coarser towards the base, the interstices 
transversely rugulose, flat, the ninth raised towards the apex. Beneath coarsely, the abdomen very 
sparsely and finely, punctate; first ventral segment slightly depressed along the middle in the ¢. 
Prosternal sulcus shallow, terminating anteriorly in a faint arcuate ridge. Legs rugosely punctate ; 
tibia somewhat curved externally, the anterior and intermediate pairs with a sharp tooth at the inner 
apical angle, in addition to the usual uncus. 
Length 24, breadth 1 millim. (¢ 2.) 
Hab. Guatemata, El Tumbador, Pacific slope, 3000 feet (Champion). 
One pair. More robust and a little larger than C. parva (Kirsch) (the type of 
which I have seen), the rostrum stouter, the apices of the elytra more produced, &c. 
2. Cercobaris brevicauda, sp. n. 
Oblong, narrow, subopaque above, black, with an xneous lustre, almost glabrous. Head closely punctate ; 
rostrum exceedingly stout, finely strigoso-punctate. Prothorax conical, nearly as long as broad, 
coarsely, densely punctate. Scutellum oblong, rugose. Elytra gradually narrowing from the rounded 
humeri, each with a small angular prominence at the apex; rather coarsely punctate-striate, the 
interstices at the base not wider than the stris, transversely rugose, flat, the ninth raised towards 
the apex. Beneath very coarsely, the abdomen finely, punctate. Prosternal sulcus deep, the ridge on 
each side extending along the basal process behind the coxe and gradually sloping anteriorly. 
Length 23, breadth 1 millim. (<.) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One male, somewhat imperfect. Differs from C. fortirostris in the deep prosternal 
sulcus, the walls of which extend backward behind the coxe, the conical prothorax, 
the oblong scutellum, and the more coarsely punctate-striate elytra.
