PHYSOBARIS.—TRACHYBARIS. 453 
eyes ; rostrum strongly arcuate, a little longer than the head and prothorax, closely punctate ; antennal 
club with the basal joint shining and less densely pubescent than the rest of its surface. Prothorax 
not much broader than long, subcylindrical, rounded at the sides anteriorly, and feebly constricted in 
front; densely, rugosely punctate, the punctures transversely confluent, the dise foveate on each side 
behind the middle. Scutellum almost flat, smooth. Elytra moderately long, the dise strongly, trans- 
versely undulate, and with a large, rounded, tuberculiform prominence towards the apex, the humeri 
oblique and not prominent ; with rows of rather large oblong punctures placed along narrow striz, the 
interstices uneven, densely, irregularly, confluently punctate, and here and there narrowly subcostate at 
the sides, the punctures much smaller than those of the strie. Beneath coarsely, the abdomen very 
sparsely and finely, punctate; first ventral segment broadly excavate down the middle. Anterior femora 
strongly, the others more feebly, clavate ; anterior tibie slightly widened, the claw moderately long. 
Length 44, breadth 14 millim. (<d.-) 
Hab. Guatemata, Purula in Vera Paz (Champion). 
One male. More elongate than P. intricata, the entire basal joint of the antennal 
club shining, the prothorax subcylindrical, the elytra less nodose at the middle, and 
with the punctures of the striae much larger than those of the interstices and the 
humeri less prominent, the anterior legs stouter. The foveee on the prothorax may 
be an accidental development. 
TRACHYBARIS, gen. nov. 
Mandibles bifid at the tip, strongly decussate ; rostrum moderately long, almost straight, the scrobes narrow, 
rapidly descending ; antennal club stout, ovate, densely pubescent; head small; eyes narrow, strongly 
transverse ; prothorax gibbous, shortly tubulate in front, very deeply sinuate at the base, the hind angles 
projecting as far backwards as the truncated median lobe; scutellum free, flat, transversely quadrate ; 
elytra lobed at the base, nodose, the humeri oblique, leaving the upper portion of the mesothoracic 
epimera largely exposed from above ; pygidium fully exposed, vertical, strongly transverse; prosternum 
flattened, with two oblique, impressed lines in front, the basal process broad; mesosternum depressed, 
exposed ; anterior coxe large, exserted, separated by rather more than their own width ; femora feebly 
clavate, unarmed, obsoletely sulcate beneath ; tibie strongly unguiculate and also armed with a sharp 
tooth at the inner apical angle; tarsi rather slender, with the bilobed third joint well-developed, the 
claws long, contiguous at the base ; body robust, oblong-ovate, metallic, rugose and nodose, almost 
glabrous above. 
Type, 7’. celuta. 
The single species upon which this genus is based cannot be included under Baris, 
even in the widest sense. The long, almost straight rostrum, the lobed base of the 
elytra, the prominent, largely developed mesothoracic epimera, and the rugose, tuber- 
culate upper surface of the body are characteristic. ‘lhe widely separated anterior 
cox, the prominent mesothoracic epimera, &c., separate Trachybaris from Lepidobaris. 
1. Trachybaris celata, sp.n. (Tab. XXII. tigg. 3,34, ¢ .) 
Opaque, shining along the middle beneath, cupreous, the depressed portions of the elytral surface greenish. 
Head rugosely punctate; rostrum about as long as the head and prothorax, moderately stout, slightly 
arched above (as seen in profile), almost straight and flattened beneath, densely, longitudinally rugose, 
the antenne inserted near the middle. Prothorax strongly transverse, somewhat rounded at the sides, 
abruptly narrowed in front ; densely, rugosely punctate and sparsely granulate, here and there nodose, 
depressed along the middle at the base, and with a small A-shaped hump in the centre and a short oblique
