320 RHYNCHOPHORA. 
hair-like scales, the legs and under surface clothed with similar scales. Head closely punctate, with two 
compressed, conical tubercles between the eyes in front in the 2, the latter very narrowly separated 
above; rostrum moderately stout, feebly curved, about as long as the head and prothorax, punctato- 
sulcate in its basal half, and sparsely punctate thence to the tip, the antennee inserted a little before the 
middle. Prothorax transversely subquadrate, abruptly narrowed and constricted in front, strongly 
bisinuate at the base, the sides angularly dilated at the middle inferiorly (appearing bisinuate when 
viewed from above); sparsely, finely punctate, except along the smooth space down the centre, the 
punctuation becoming much coarser at the sides. Elytra much wider than, and about two and one-half 
times as long as, the prothorax, dilated at the sides below the humeri, which are obliquely truncated 
in front; very coarsely seriate-punctate, the interstices somewhat uneven and each very minutely 
uni- or biseriate punctate. Legs stout ; femora rugosely punctate and strongly dentate; tibiee punctato- 
sulcate, angularly dilated on the inner side a little before the middle, and serrulate thence to the apex. 
Length 43-54, breadth 23-3 millim. (¢ 2.)

Bugaba (Champion).—-VENEZUELA?; GUIANA; Braziu!. 
Very like C. e@neus, but with the prothorax bisinuate at the sides, and the disc 
finely punctate. Four specimens, agreeing with others from Cayenne and Brazil in 
the British Museum. The tubercles on the head were not noticed by Fahreeus, but he 
may not have seen both sexes.

Oval, convex, shining, eeneous, the antenne obscure ferruginous; almost glabrous above, the legs and under 
surface with minute scales. Head closely punctate, abruptly swollen between the eyes anteriorly in the 
and feebly so in the ¢, the eyes almost contiguous ; rostrum ( ¢) stout, feebly curved, about as long 
as the prothorax, seriato-punctate, feebly carinate, and dull in its basal half, and sparsely punctate and 
shining thence to the tip, (2) sparsely punctate throughout and more shining, the antenne inserted far 
before the middle in both sexes. Prothorax transverse, rounded at the sides anteriorly, constricted and 
narrowed in front, and bisinuate at the base; the disc coarsely, obliquely strigose and also punctate, 
without distinct median carina, the flanks with very coarse punctures. Elytra subtriangular, much 
wider than the prothorax, the humeri rounded externally ; punctato-sulcate, the punctures coarse and 
subquadrate at the base, becoming smaller, shallower, and more scattered towards the apex, the inter- 
stices move or less convex (3, 5, and 7 usually a little more raised than the others), transversely rugulose 
at the base, all smoother and strongly costate on the apical declivity. Legs stout; femora closely 
punctate ; tibie punctato-sulcate, the intermediate pair with a sharp triangular tooth, and the anterior 
and posterior pairs angularly dilated, on the inner side about the middle, and all more or less serrulate 
thence to the acutely toothed apical angle. |

Hab. Gtatemata (Sallé); Panama, Bugaba, David, and Caldera in Chiriqui 
(Champion).—Sovtu America ! 2, Cayenne 2. 
Found in plenty in the low savana-country of Chiriqui, singly in Guatemala. 
Central-American specimens differ from those of the southern continent in having the 
prothorax more coarsely strigose, and the elytral interstices smoother and more strongly 
costate on the apical declivity.
