506 RHYNCHOPHORA. 
1. Metadupus nodatus. (Tab. XXV. figg. 1, 1a, var. apicatus, 2 .) 
Metadupus nodatus, Boh. in Schénh. Gen. Cure. iv. p. 168°. 
Hab. Mexico (ex coll. Flohr), Vera Cruz} (Mus. Holm.), Toxpam, Orizaba (Sad/é) ; 
GuaTEMALA, Cerro Zunil, Purula (Champion), Coban (Conradt); Nicaracua, Chontales 
(Belt, Janson); Panama, Volcan de Chiriqui, Bugaba, Tolé (Champion).—Ecuapor 
(coll. fry). 
Var. a. The prothorax and elytra more nodose, the elytra with the sutural interstice gibbous at the commence- 
ment of the apical declivity. 
Hab. Mexico (ex coll. Flohr); Guatemaua, Cerro Zunil, San Gerénimo (Champion) ; 
Panama, Volcan de Chiriqui (Champion). 
Var. 3. The subapical prominences produced posteriorly and each furnished with a pencil of long, bristly, 
fulvous hairs. 
Metadupus apicatus, Boh. loc. cit. p. 169’. 
Hab. Mexico, Tultepec [Toulcpec?] (Mus. Holm.) ; Guatemaua, Cerro Zunil, Capetillo 
(Champion); Panama, Bugaba, Volcan de Chiriqui (Champion). 
Amongst the long series of this species obtained by us, five specimens only belong to 
the var. 6. All the forms occurred at Cerro Zunil. 
The tubercles of the prothorax and elytra vary in size, being particularly prominent 
in typical J. apicatus, and small on the prothorax of M. nodatus. Some of the 
specimens from Chiriqui have a large dark space on the disc of the prothorax and 
elytra. I have seen Boheman’s types. 
MACROMERUS. 
Macromerus, Schénherr, Cure. Disp. Meth. p. 285 (1826); Gen. Cure. iv. p. 183; Lacordaire, 
Gen. Col. vii. p. 126. 
The species of this Tropical-American genus agree in having the anterior legs of the 
male more or less elongated, and their tarsi clothed with long projecting hairs; the 
antennal club ovate, with distinct sutures; the second joint of the funiculus elongate 
(except in MV. leuconotus); the eyes very large and finely facetted ; the femora clavate, 
and unidentate, the posterior pair reaching beyond the apex of the elytra; the second 
ventral segment almost as long as the third and fourth united; the rostral canal nearly 
or quite reaching the front of the metasternum. The Central-American species may 
be separated thus :— 
a. Second joint of the funiculus much longer than the first. 
a'. Elytral interstices distinctly granulate. 
a. Elytra with an angulate subapical fascia and a transverse patch on 
each shoulder yellowish-white or white . . . . . . . . .~ succinctus, Chevr. 
6", Elytra with an irregular, interrupted, black fascia . . . . . stigmaticus, Boh.
