276 RHYNCHOPHORA. 
the process of the first ventral segment of the male, which is very similar to that of 
E. antilope. EE. granatensis, Chevr., from Honda, Colombia, is described as having 
a similarly sculptured prothorax. 
4, Hrodiscus bituberculatus, sp.n. (Tab. XIV. fig. 14, head and rostrum, ¢.) 
Elongate, shining, nigro-piceous or piceous; the alternate elytral interstices each with a row of very long, 
erect, whitish, bristly hairs. Head smooth, the eyes almost contiguous above; rostrum feebly curved, 
swollen at the middle beneath in the ¢, a little shorter than the elytra in both sexes, with the basal half 
much thickened, laterally sulcate, and longitudinally rugulose, the apical half almost smooth ; antenne in 
both ¢ and @ inserted at about the middle of the rostrum, rather stout, joints 2-7 of the funiculus 
obovate, 2 a little longer than 3, the club ovate. Prothorax much longer than broad, very convex, 
rounded at the sides, feebly constricted in front and strongly so behind, the short basal portion subcylin- 
drical, the surface smooth. Elytra moderately long, not or very little wider than the prothorax, 
subparallel to near the middle, constricted at the base, the humeri obtuse; obsoletely seriate-punctate, 
the punctures sometimes traceable towards the suture and outer margin only, the setigerous impressions 
more distinct. Meso- and metasternum and the sides of the abdomen with a few widely scattered 
punctures. First ventral segment with two very small tubercles in the middle at the apex, and the fifth 
unimpressed, in the ¢. Femora each with a short tooth. Tibie simply sinuate. Tarsal claws with a 
long fine tooth. 
Length 43-6, of the rostrum 23-3, breadth 12-14 millim. (¢ @.) 
Hab, Panama, Bugaba (Champion). 
Six specimens, the two without abdominal tubercles assumed to be females, though 
not differing from the others in the length and thickness of the rostrum. This species 
much resembles £. levigatus, but has the rostrum in both sexes much shorter, basally 
thickened, and laterally sulcate, the claws toothed, and the first ventral segment of the 
male bituberculate. LH. scolopax, Faust, from Venezuela, is also very similar, but it 
has a broader and more globose prothorax, the anterior femoral tooth larger, &c. 
5. Erodiscus levigatus, sp. n. 
Elongate, narrow, shining, nigro-piceous, the legs and antennsw rufo-piceous; the elytral interstices 2 and 4 
each with a scattered series of very long, erect, rigid, whitish sete. Head almost smooth; eyes very 
narrowly separated above; rostrum about as long as the body in the 9, a little shorter and more 
distinctly thickened towards the base in the ¢, longitudinally rugulose in its basal half, smoother thence 
to the apex, the antenne inserted at a little beyond the middle in the ¢, and slightly before the middle 
in the 9, joint 2 of the funiculus much longer than 3, the club oblong-ovate. Prothorax much longer 
than broad, very convex, rounded at the sides, slightly constricted in front, the short, narrow, basal 
portion subcylindrical, the base and apex somewhat coarsely punctured, the rest of the surface smooth. 
Elytra moderately long, very little wider than the prothorax, subparallel to near the middle, flattened on 
the disc anteriorly, abruptly constricted at the base, the humeri swollen and obtuse ; very finely seriate- 
punctate, the punctures somewhat widely separated, the setigerous impressions on the interstices 2 and 4 
minute. Meso- and metasternum and abdomen with a few coarse punctures at the sides. First ventral 
segment transversely, and the fifth broadly and longitudinally, depressed in the middle at the apex in 
the ¢, the fifth with or without a shallow depression in the 2. Anterior femora distinctly, and the two 
other pairs obsoletely, toothed. Tuibic simply sinuate. First tarsal joint about as long as the others 
united; tarsal claws simple. 
Length 44-63, of the rostrum 37-57, breadth 14-1? millim. (¢ 2.)
