CHALCODERMUS. o21 
9. Chalcodermus dentipes, sp. n. (Tab. XVII. figg. 6, 6a, 2 ; 64, ant. leg.) 
Broad-oval, convex, shining, cupreo-eneous, the antennse obscure ferruginous; almost glabrous above. Head 
coarsely punctate, smooth and foveate between the eyes, which are narrowly separated; rostrum stout, 
feebly curved, slightly longer than the head and prothorax, sparsely, very finely punctate, the antennz 
inserted a little before the middle. Prothorax strongly transverse, parallel at the sides behind, much 
narrowed and constricted in front, and bisinuate at the base; obliquely strigose towards the sides and 
punctate on the middle of the disc, except along the smooth median line. EHlytra much wider than the 
prothorax, somewhat triangular, slightly dilated at the sides below the humeri, which are obliquely 
truncate; very coarsely seriate-punctate, the interstices rather uneven, 3 and 5 alittle raised at the base, 
all excessively minutely and irregularly uni- or biseriate-punctate. Legs very stout; femora rugulosely 
punctate, strongly dentate, the tooth blunt at the tip; tibia deeply punctato-sulcate, the anterior and 
posterior pairs angularly dilated, and the intermediate pair armed with a strong tooth, on the inner edge 
at or before the middle, and all serrate thence to the apex. 
Length 51, breadth 34 millim. ( 2.) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One specimen. In this insect the legs are very stout; the tibia are so deeply 
sulcate that the intervening spaces appear to be sharply carinate, and they are also 
very distinctly serrate within, the intermediate pair being armed with a sharp median 
tooth; and the elytral interstices are not at all costate on the apical declivity. It 
is broader and more oval than C. foveolatus. The serration of the tibie is stronger 
than in C. serripes. 
10. Chalcodermus foveolatus, sp.n. (Tab. XVII. fige. 7, 7a, 2.) 
Oblong-oval, shining, eneous or wneo-cupreous, the elytra sometimes mottled with reddish, the antennw 
obscure ferruginous; clothed with very minute, scattered, hair-like, whitish scales, which are often 
abraded on the upper surface. Head closely punctate, the eyes rather narrowly separated ; rostrum 
stout, curved, about as long as the head and prothorax, sparsely punctate, the antenne inserted before 
the middle. Prothorax transverse, rounded at the sides anteriorly, abruptly narrowed and constricted 
in front, and subparallel behind, the base strongly bisinuate; very coarsely, closely punctate, except along 
a narrow smooth space down the middle, the punctures confluent on each side of the dise anteriorly and 
separated by oblique ruge. Elytra much wider than the prothorax, narrowing very gradually to 
the middle, the humeri obliquely truncate and usually rather prominent laterally ; seriato-foveolate, the 
interstices sparsely, excessively minutely punctate, 3 and 5 costate throughout and 7 costate at the base 
and apex. Legs stout; femora closely punctate and sharply dentate; tibiw punctato-sulcate, the 
intermediate pair with a sharp median tooth, the anterior pair subangularly dilated before the middle, 
and the hind pair sinuate, all serrulate within, except at the base. 
Length 33-5, breadth 2-22 millim. (d 2.) 
Hab. Mexico, San Andres Tuxtla, Toxpam, and Playa Vicente (Sal/é), Teapa 
(H. H. Smith); Guaremata, Zapote (Champion). 
Ten specimens. Near C. wneus, but with the alternate elytral interstices costate 
and the humeri obliquely truncated, the prothoracic punctuation here and there 
confluent and separated by oblique ruge, the head not bituberculate between the eyes 
in either sex.
