CALOPUS. 
Calopus, Fabricius, Syst. Ent. p. 182 (1775) ; Lacordaire, Gen. Col. v. p. 702. 
Three species only of this genus have been described, one from Europe and two from 
North America. Four are now added from Central America. The genus is remarkable 
from having the antenne inserted in the canthus which extends partly across the eye. 
The males of the Central-American species have the antenne subserrate and almost as 
slender as in Sparedrus, and they thus differ considerably from the type. Calopus 
much resembles some genera of Longicornia. 
1. Calopus mixtus. (Tab. V. fig. 19, ¢.) 
Very elongate, testaceous or piceo-testaceous, slightly shining, thickly clothed with ashy decumbent hairs, the 
entire upper surface very closely and coarsely punctured. Head rather more sparsely punctured between 
the eyes, the latter black and somewhat widely separated; antenne (d ) very long and slender, reaching 
nearly or quite to the end of the elytra, joint 2 about one-third of the length of 3, the outer joints sub- 
serrate ; prothorax about as long as broad, the sides rounded anteriorly and very gradually narrowing and 
almost straight behind, the hind angles subrectangular, the disc somewhat flattened and with a shallow 
oblique impression on each side and a transverse one before the base; elytra with numerous scattered, 
smooth, irregular, slightly raised spots ; beneath very closely punctured ; the fifth ventral segment feebly 
emarginate in the male. 
Length 94-133 millim. (d.)
