ERODISCUS. 275 
very coarsely punctured at the sides, the ventral segments also with coarse scattered punctures. First 
ventral segment transversely raised and sublamellate in the middle at the apex in the g. Femora each 
with a very short tooth beneath. Tibis sinuate; the anterior pair with a short submedian tooth within, 
and hollowed and ciliate thence to the apex. Tarsal claws with a long, fine tooth. 
Length 4-53, of the rostrum 34-5, breadth 13-13 millim. (¢ @.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion).—Souru America? *, Cayenne °, 
Brazil. 
Four specimens. The coarsely, confluently punctured, carinate prothorax, and the 
toothed anterior tibie in both sexes, separate this insect at once from the other 
Central-American forms.

2. Erodiscus appendiculatus, sp. n. (Tab. XIV. fig. 11, profile of abdo- 
men &c., 3.) 
Elongate, shining, nigro-piceous or black, the antenne, the rostrum, the femora at the base and apex, the tibie, 
and tarsi, more or less rufo-piceous; the prothorax, the alternate interstices of the elytra, the under 
surface, and legs sparsely clothed with very long, erect, yellowish, bristly hairs. Head minutely punctate, 
the eyes very narrowly separated above; rostrum feebly curved, a little shorter than the body, slightly 
thickened towards the base, longitudinally rugulose in its basal half and much smoother thence to the 
apex; the antenne inserted near the middle in both sexes, joint 2 of the funiculus much longer than 3. 
Prothorax longer than broad, globose anteriorly, narrow and subcylindrical at the base, and constricted 
at the apex, the punctuation coarse, scattered on the disc and confluent on the flanks, a narrow space 
along the middle of the dise impunctate. Elytra moderately long, not or very little wider than the 
prothorax, subparallel in their basal half, constricted in front, the humeri obtuse ; rather coarsely seriate- 
punctate, striate laterally, the scattered interstitial punctuation fine. Meso- and metasternum (except 
along the middle), the ventral segments 2-5, and 1 at the sides and in front, coarsely, sparsely punctate, 
the first segment in the ¢ produced in the middle posteriorly into a long, stout, flattened, truncated 
process (fig.11). Anterior femora distinctly, and the other two pairs obsoletely, toothed. Tibize simply 
sinuate. Tarsal claws with a long, fine tooth. 
Length 4-5, of the rostrum 22-34, breadth 13-17 millim. (¢ @.) 
Hab. Guatremata, San Juan and Senahu in Vera Paz (Champion). 
Five males and four females, all from the forest-clad mountains north of the Polochic 
Valley. This insect is readily recognizable by the long, truncated process of the first 
ventral segment in the male. Apart from this character, the sparsely punctate disc of 
the prothorax and the absence of the tooth on the anterior tibie separate it from 
Ei. antilope. 
3. Erodiscus lamellatus, sp. n. (Tab. XIV. figg. 12, ¢; 13, 13a, 2.) 
Varying in colour from black to rufo-piceous ; the general structure, sculpture, and vestiture as in ZH. appendi- 
culatus, except that the punctuation of the prothorax is usually closer on the disc (leaving always a smooth 
space down the middle) and that of the abdomen sparser; the first ventral segment in the ¢ raised and 
broadly truncato-lamellate in the middle at the apex (fig. 12). 
Length 3-5, of the rostrum 13-33, breadth 1-13 millim. (d @.) 
Hab. Ntcaraaua, Chontales (Janson: 2); Panama, Bugaba (Champion: 3 2.) 
A southern representative of E. appendiculatus, differing constantly in the form of
