508 RHYNCHOPHORA. 
4. Macromerus flavocinctus, sp.n. (Tab. XXV. figg. 5, 5a, 2.) 
Oblong-ovate, black; clothed with: small, intermixed, blackish and ochreous scales, the latter condensed 
into a narrow line around the eyes, a sharply-defined streak on each side of the disc of the prothorax 
(which is continued on to the base of the elytra), and numerous small scattered:spots and a common, 
slightly curved, postmedian fascia on the elytra; the under surface, femora, and tibiw sparsely clothed 
with cinereous scales. Head densely punctate, the eyes very large; rostrum rugosely punctate and 
carinate to about the middle, and very sparsely, finely punctate thence to the apex, the apical half almost 
smooth in the @. Prothorax nearly as long as broad, carinate, and sparsely, rather coarsely umbilicate- 
punctate. Elytra broadly depressed down the suture anteriorly; seriate-punctate, the interstices 
granulate, 3 and 5 more or less raised at the base. Anterior tibizw serrulate within, and bowed at the 
apex, in the ¢. 
Length 93-131, breadth 44-5? millim. (¢ Q.) 
Hab. Guatemata, El Tumbador and Cerro Zunil, Pacific slope (Champion). 
Four specimens. Near WM. tenuicinctus, but with the prothorax sharply bivittate, 
the median carina more prominent, the umbilicate punctures coarser, the prothoracic 
and elytral vestiture in great part black, the postmedian fascia a little curved. 
5. Macromerus bicinctus, sp.n. (Tab. XXV. figg. 6, 6a, 3.) 
Oblong-ovate, black; sparsely clothed with small fulvous scales, the elytra with two narrow fulvous fascie 
(one at the base and the other beyond the middle), and for the rest thickly clothed with intermixed black 
and fulvous scales, the latter condensed into small spots on the apical declivity, the vestiture of the 
femora and tibie cinereous. Head densely punctate, foveate between the eyes, which are very large and 
rather narrowly separated; rostrum rugosely punctate and carinate to about the middle, and sparsely, 
finely punctate thence to the apex, smoother in the 2. Prothorax broader than long, much narrowed 
and feebly constricted in front; densely punctate and obsoletely carinate. Elytra broadly depressed 
down the suture anteriorly; seriate-punctate, the interstices granulate, 3, 5, and 7 slightly raised. 
Anterior tibia in the ¢ much thickened externally towards the apex, appearing strongly sinuate on their 
outer edge. 
Length 10-114, breadth 43-53 millim. (¢ 2.) 
Hab. Costa Rica, Azahar de Cartago, Monte Redondo (Underwood). 
Three specimens. ‘This species may be readily identified by the bifasciate elytra.. 
The anterior tibiz of the male are thickened at the apex, as in M. succinctus. 
6. Macromerus flavofasciatus, sp.n. (Tab. XXV. figg. 7,74, 2.) 
Oblong-ovate, dull, black; the upper surface thickly clothed with small blackish scales, the elytra with a 
broad yellow fascia before the middle, the vestiture of the under surface and legs sparse and cinereous in 
colour. Head rugulosely punctate, the eyes very large and rather narrowly separated ; rostrum curved, 
moderately long, subcylindrical, rugulosely punctate and carinate at the base, and for the rest very 
sparsely, finely punctate, the antenne inserted far behind the middle, joint 2 of the funiculus elongate. 
Prothorax broader than long, rapidly narrowing from a little behind the middle, the sides becoming 
parallel towards the base; densely, rugosely punctate. Elytra seriate-punctate, the interstices almost 
flat, punctulate, and obsoletely granulate, the disc broadly depressed along the suture anteriorly. Beneath 
with scattered coarse punctures intermixed with very minute ones. Femora clavate, unidentate. 
Length 84-1232, breadth 33-53 millim. ( 9.) 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
Three specimens. Easily identified by the broad yellow fascia of the elytra, the rest 
of the vestiture of the upper surface being black.
