Var. 
The raised elytral interstices sinuous, and here and there connected one with another, 3 and 5 usually the 
most prominent, the fovee large and subquadrate. 
Hab. Panama, Bugaba, David, Volcan de Chiriqui (Champion). 
Apparently the commonest species of the genus within our limits, the variety being 
connected by intermediate forms. It is recognizable by its shining black surface and 
very coarse sculpture, the prothorax coarsely strigose, the rugee becoming longitudinal 
on the anterior part of the disc. ‘The elytra are subtriangular, closely seriato-foveolate, 
with the humeri obliquely truncated in front. The anterior and intermediate cox 
are narrowly separated. 
18. Chalcodermus serripes. (Tab. XVII. figg. 12,12a; 124, anterior tibia.) 
Chalcodermus serripes, Fahy. in Schonh. Gen. Cure. iv. p. 885°. 
Hab. Nortu America, Brownsville, Texas (ex Wickham).—MeExico, Toxpam, Playa 
Vicente (Sallé), Jalapa, Oaxaca (Hoge); Nicaracua, Mosquito Coast (Jus. Brit.).— 
Brazit !, Rio Janeiro. 
Easily distinguishable by its elongate-triangular, coarsely seriate-punctate elytra, and 
closely, obliquely strigose prothorax. The tibie are sinuate and serrate within, except 
at the base, and strongly mucronate at the inner apical angle. The first ventral 
segment is depressed down the middle in the male. The specimen from Nicaragua in 
the British Museum is labelled C. aurichalceus, Schmidt. 
19. Chalcodermus crassipes, sp. n. (Tab. XVII. figg. 13, 134, 2 ; 134, 
anterior tibia.) 
Broad-oval, convex, moderately shining, black, sparsely clothed with small, hair-like, whitish scales. Head 
closely, rugulosely punctate, the eyes large, coarsely facetted, and almost contiguous above and beneath ; 
rostrum feebly curved, rather stout, about as long as the head and prothorax, rather sparsely punctate, 
the antenne inserted at about the middle. Prothorax transverse, feebly constricted in front, parallel 
behind, the sides rounded and converging anteriorly, the base strongly bisinuate; coarsely, confluently 
punctate, and carinate down the middle for the greater part of its length. Elytra one-half wider than 
the prothorax, subparallel in their basal half (as seen from above), angularly dilated at the sides at some 
* The locality is given as “ Toulepec.”
