RHINOMALUS. 535 
2. Rhinomalus signatus, sp. n. (Tab. XVII. fig. 6.) 
Piceus, nitidus, rostro rufo, elytris flavo-bimaculatis ; antennis articulis basalibus 5 rufescentibus, articulis 
ultimis 6 fere equaliter crassis, obscuris ; prothorace parcissime punctato; elytris fere estriatis. 
Long. 2-27 millim. 
Hab. Guaremata, Chacoj in Vera Paz (Champion). 
This insect agrees with R. vicinus in the fact that the terminal three joints of the 
antenne do not formaclub. The head is broad between the eyes, which are very 
large. The thorax is greatly narrowed behind, its punctures very few, the intra-lateral 
line quite distinct. The elytra are almost destitute of sculpture, except that the sutural 
stria is distinct behind. The thinner parts of the legs are yellow, the thicker parts 
darker. 
§2. Anterior coxal cavities open ; antenne clavate, joints 9-11 broader than 
the preceding. (XENORHINUS.) 
3. Rhinomalus anthracinus, sp. n. (Tab. XVII. fig. 7.) 
Niger, nitidus, rostro, antennarum parte basali pedumque partibus tenuibus rufis ; antennis articulis ultimis 
tribus erassioribus ; prothorace punctato, linea intra-laterali tantum ad basin impressa; elytris omnium 
obsoletissime seriatim punctatis, estriatis. 
Long. 2-23 millim. 
Hab. Mexico (Sallé). 
This species is readily distinguished from &. vicinus and R. signatus by the different 
form of the antenne, as well as by the colour, and by the thoracic stria being much 
abbreviated in front. The absence of striation on the elytra is nearly complete, as I 
cannot trace either sutural or intra-humeral strie; there are, however, some excessively 
fine punctures placed in the perfectly linear manner that indicates either rudimentary 
or vestigial strize in Lemophlat. 
I have adopted the name from M. Sallé’s collection, where this insect was labelled 
Rhinomalus anthracinus, Deyr. This species, or the following one, is probably the 
Xenorhinus truquii, Lec. and Horn (Class. Col. N. Am. ed. 2, p. 134), from ‘* Mexico.” 
4. Rhinomalus chiriquensis, sp. n. 
Niger, nitidus, rostro, antennarum parte basali pedumque partibus tenuibus rufis; antennis articulis ultimis 
tribus crassioribus; elytris stria intra~humerali subtili discreta. 
Long. 24 millim. 
Hab. Mexico, Forests above Jalapa (Flohr); Panama, Bugaba, Volcan de Chiriqui 
(Champion). | | 
This insect chiefly differs from R. anthracinus by the possession of a distinct stria on 
each elytron. ‘The serial punctuation is even more indistinct than it is in that species.
