322 RHYNCHOPHORA. 
11. Chalcodermus variolosus, sp. n. | 
Oval, rather broad, moderately shining, obscure neous, the antenne and the tips of the tarsi ferruginous ; 
the elytra, under surface, and legs clothed with minute, scattered, hair-like, whitish scales. Head 
sparsely punctate, the eyes well-separated; rostrum stout, curved, about as long as the head and 
prothorax, sparsely punctate, the antenne inserted before the middle. Prothorax broad, transverse 
rounded at the sides anteriorly, and constricted and narrowed in front, the sides sinuate as seen from 
above, the base strongly bisinuate; coarsely, confluently punctate, except along the narrow, smooth, 
well-defined, median space, the punctures here and there separated by short oblique ruge. LElytra 
much wider than the prothorax, somewhat triangular, the humeri obliquely truncate; coarsely seriate- 
punctate, the punctures placed at unequal distances from each other, the interstices somewhat uneven, 
distinctly uni- or biseriate-punctate, 3, 5, and 7 slightly raised, becoming costate at the base and apex. 
Legs stout; femora closely punctate, sharply dentate ; tibie punctato-sulcate, the anterior and inter- 
mediate pairs subangularly dilated at or before the middle, and the hind pair almost straight, on their 
inner edge. 
Length 43-54, breadth 24-33 millim. (¢ 9.) 
Hab. Muxtco, Jalapa (Hége); Guatemala, Las Mercedes, Zapote ( Champion). 
Six specimens, all but one from the Pacific slope of Guatemala. Duller and 
relatively broader than C. foveolatus, the sculpture of the prothorax and elytra not so 
coarse, the latter with the alternate dorsal interstices not costate throughout, the 
seriate punctures less regularly arranged, and the interstices more distinctly punctate, 
the intermediate tibie less distinctly serrulate within, and with the median tooth 
reduced to an angular dilatation. 
12. Chalcodermus curvipes, sp.n. (Tab. XVII. figg. 8,8 a, 3 ; 84, ant. tibia.) 
Oval, convex, shining, eeneous, the antenne ferruginous ; almost glabrous above. Head rugulosely punctate, 
the eyes nearly contiguous; rostrum stout, feebly curved, nearly as long as the head and prothorax, 
finely punctate, the punctures seriately arranged towards the base, the antenne inserted before the 
middle, Prothorax transverse, gradually narrowing from the base, rounded at the sides anteriorly, and 
constricted in front, the base bisinuate ; coarsely, closely punctate, except upon the narrow, smooth, 
median line, the punctures here and there confluent and separated by short oblique rugs. Elytra much 
wider than the prothorax, subtriangular, the humeri obliquely truncate; coarsely and closely seriate- 
punctate, the interstices smooth, narrow, and rather uneven, becoming convex on the apical declivity. 
Legs very short, stout; femora closely punctate, each armed with a long, narrow, blunt tooth; tibize 
punctato-sulcate, the anterior and intermediate pairs bowed inwards, and all three pairs subangularly 
dilated within at about the middle and serrulate thence to the apex. 
Length 34, breadth 2,1, millim. (d.) 
Hab. British Honpuras, Rio Hondo (Blancaneaua). 
One specimen. In this species the anterior tibiz are alittle more bowed than usual, 
and the three pairs are subequally dilated at about the middle within, whereas in 
C. calidus and C. dentipes the intermediate pair are toothed on the inner side. 
Compared with C. lineatus, the prothorax is less strongly strigose, the elytral interstices 
are much narrower, the humeri are less rounded, and the hind tibie are more sinuous 
within.
