CHALCODERMUS. 323 
13. Chalcodermus lineatus, sp.n. (Tab. XVII. figg. 9, 9 a, 9; 94, ant. tibia.) 
Oval, convex, shining, neous or cupreous, the elytra sometimes reddish, the antennze obscure ferruginous ; 
the elytra with minute, ‘scattered, hair-like scales, which are more abundant and condensed into a 
narrow vitta on the third and seventh interstices, the legs and under surface clothed with similar scales. 
Head closely punctate, the eyes narrowly separated; rostrum stout, longer than the head and prothorax, 
feebly curved, seriate-punctate in its basal half, and sparsely punctate thence to the apex, the antenne 
inserted before the middle in the ¢ and at about the middle in the 9. Prothorax transverse, somewhat 
rounded at the sides anteriorly, constricted and narrowed in front, and strongly bisinuate at the base, 
the hind angles subrectangular ; coarsely, obliquely strigose, sharply carinate down the middle anteriorly, 
and also punctate, the ruge on the disc becoming transverse behind and longitudinal in front. Elytra 
subcordate, much wider than the prothorax, slightly dilated at the sides below the humeri, which are 
rounded externally ; very coarsely seriate-punctate, the interstices flat, becoming convex on the apical 
declivity, and with a few excessively minute punctures. Legs stout ; femora rugosely punctate and strongly 
dentate ; tibis punctato-sulcate, the anterior and intermediate pairs angularly dilated at about the 
middle, and the hind pair sinuate, within. 
Length 32-5, breadth 24-37, millm. (¢ 2.) 
Hab. Mexico, Ventanas in Durango (Hodge); GuatTemMana, San Juan and San 
Gerénimo in Vera Paz, Zapote (Champion). 
Seven specimens. Distinguishable by the subcordate, convex, coarsely seriate- 
punctate elytra, with the interstices smooth, flat to about the middle, and the third and 
seventh (which are usually golden) each with a compact line of minute whitish scales ; 
the coarsely, obliquely strigose prothorax ; and the brilliant eneous or cupreous colour. 
14. Chalcodermus radiatus, sp. n. 
Oval or oblong-oval, shining, obscure seneous, the elytra sometimes mottled with reddish, the antenne in part 
ferruginous ; the elytra, and the legs and under surface, with scattered, minute, whitish, hair-like scales. 
Head sparsely punctate, feebly foveate between the eyes, which are narrowly separated; rostrum curved, 
stout, as long as the head and prothorax, sparsely punctate, the punctures seriately arranged in its basal 
half, the antennz inserted before the middle. Prothorax transverse, rounded at the sides anteriorly, 
constricted and narrowed in front, and bisinuate at the base; sparsely, and in some specimens very 
finely, punctate on the middle of the disc, except along the smooth median line, the punctures towards 
the sides and apex here and there confluent and separated by prominent oblique ruge. Elytra much 
wider than the prothorax, subparallel towards the base, the humeri obliquely truncated, but not dilated 
laterally ; very coarsely seriate-punctate, the interstices almost flat and very faintly seriate-punctate. 
Legs moderately stout ; femora finely punctate and sharply dentate; tibie shallowly punctato-sulcate, 
each angularly or subangularly dilated at or before the middle within. 
Length 31-4, breadth 13-2 millim. 
Hab. Guaremata, Cahabon in Vera Paz (Champion); Panama (Boucard), David, 
Caldera, Volcan de Chiriqui (Champion). 
Eight specimens, one only being from Guatemala, and that perhaps not conspecific, 
it having the prothorax as coarsely and closely punctured as in C. eneus. The present 
insect has the head flattened between the eyes in both sexes, the prothorax more or less 
strigose laterally and anteriorly, and the elytra not dilated at the sides below the humeri, 
characters separating it from the above-mentioned species. The relatively narrower 
elytra distinguish C. radiatus from the still more nearly allied C. metallinus (Fabr.),
