524 RHYNCHOPHORA. 
of the West Indian Islands. The sculpture of the prothorax is variable, and the 
serrulation of the tibie also, even in a short series from the same locality. 
15. Chalcodermus vittatus, sp. n. 
Oval, convex, rather dull, eneo-cupreous; the elytra rufous, with the suture throughout, the second 
interstice from a little below the base to the middle, the fourth at the apex, and the sixth for the 
greater part of its length, neous, the antenne ferruginous; the elytra, under surface, and legs clothed 
with minute, scattered, whitish, hair-like scales. Head closely punctate, the eyes well-separated ; 
rostrum stout, feebly curved, about as long as the head and prothorax, sparsely punctate, the punctures 
subseriately arranged in its basal half, the antenne inserted before the middle. Prothorax transverse, 
rounded at the sides anteriorly, parallel behind, constricted and narrowed in front, and strongly bisinuate 
at the base; coarsely, closely, obliquely strigose, and also punctate, sharply carinate down the middle, 
the rugs becoming longitudinal on the disc towards the apex. Llytra much wider than the prothorax, 
subtriangular, the humeri obliquely truncate, but not prominent laterally ; coarsely seriate-punctate, the 
punctures oblong in shape, the interstices convex throughout and feebly punctulate. Legs stout; femora 
rugulosely punctate and sharply dentate ; tibie punctato-sulcate, each angularly or subangularly dilated 
near the middle within. 
Length 41-44, breadth 21-24 millim. (?<.) 
Hab. GuateMaa, Tocoy in Vera Paz (Champion). 
Two specimens. This insect resembles C. dentiferus and C. collaris, but the elytra 
are differently coloured, the humeri are less distinctly angulate, and the interstices are 
strongly convex throughout; the sculpture of the prothorax is also less coarse, and 
the rugee more oblique. 
16. Chalcodermus mexicanus, sp. n. (Tab. XVII. fige. 10, 10 a, 2; 108, 
anterior tibia.) 
Oval, rather dull, neous or eneo-cupreous, the elytra usually more or less ferruginous, mottled or fasciate 
with black, the antenne ferruginous ; somewhat thickly clothed with small, oval, yellowish and whitish 
scales, which are often condensed into narrow, angulated, interrupted fascie on the elytra. Head 
rugulosely punctate, the eyes almost contiguous ; rostrum (d ) moderately stout, curved, not longer than 
the head and prothorax, finely punctate, the punctures seriate in its basal half, ( 2 ) longer, more slender, 
and almost smooth. Prothorax a little broader than long, rounded at the sides anteriorly, constricted 
and narrowed in front, and strongly bisinuate at the base; densely, obliquely strigose, and sometimes . 
with an abbreviated median carina. Elytra much wider than the prothorax, somewhat triangular, the 
humeri rounded ; coarsely seriate-punctate, the interstices rugulosely punctulate, and all sharply costate 
throughout. Legs stout; femora rugosely punctate, sharply dentate; tibia punctato-sulcate, each 
angularly or subangularly dilated at or before the middle within. 
Length 43-61, breadth 24-31 millim. (¢ 9.) 
Hab. Mexico (Mus. Brit.; Flohr), Jalapa (Hoge), Puebla, Toxpam, Capulalpam, 
Yolos, Chiapas (Sai/é). 
We have received eight specimens of this species, which is incorrectly named 
C. pruinosus, Boh., in the British Museum. It is easily separable from all its allies 
by the comparatively coarse vestiture, the densely strigose pronotum, and the sharply 
costate elytral interstices. The squamosity of the elytra is arranged in irregular 
transverse fascie.
