EPAGRIUS. 135 
i. Epagrius opacus, sp. n. 
Niger, opacus, nudus ; prothorace densissime subtiliter punctato-ruguloso, dorso late leviter depresso, utrinque 
longitudinaliter leviter impresso ; elytris opacis, seriatim sat fortiter punctatis. 
Long. 12 millim. 
Hab. Mexico, Chiapas (Sallé); Guaremana, Totonicapam 8500 to 10,500 feet 
(Champion), Tepan (Conradt). . 
Rostrum densely punctulate, feebly impressed along the middle, with a small fovea 
on the forehead. Thorax elongate, densely covered with fine rugosities, but without 
any definite punctures; the middle is occupied by a large deplanate space limited on 
each side by a rather narrow elevation, outside which there is another longitudinal 
depression of the surface. Elytra with the surface coriaceous, and with series of not 
very large punctures placed at a considerable distance from one another. 
We have received four specimens of E. opacus—all males. They have the base 
of the elytra remarkably deeply emarginate and the shoulders considerably prolonged 
in front. A specimen from Tepan is possibly a female of this species; it is very much 
larger and broader, has the shoulders not produced, and the elytra smoother. 
This is one of two species that were labelled Synthlibonotus viator, Chevr., in Sallé’s 
collection. 
12. Epagrius jugicola, sp. n. (Tab. V. fig. 23.) 
Niger, opacus, nudus ; prothorace densissime punctato-ruguloso, dorso late depresso, utrinque longitudinaliter 
impresso ; elytris peropacis, coriaceis, seriatim fortiter punctatis. 
Long. 134 millim. 
Hab. GuaTEMALA, Volcan de Agua 8500 to 10,500 feet (Champion). 
I separate from EH. opacus two specimens of the male sex that have the sculpture of 
the upper surface coarser, and the rostrum rather longer and more distinctly impressed 
along the middle. The peculiar fine rugulose sculpture of the elytra is very remark- 
able in this species, and the serial punctures are considerably larger than they are in 
E. opacus. ‘The shoulders of the elytra are remarkably prolonged. 
13. Epagrius foveicollis, sp. n. (Tab. V. fig. 24, 2 .) 
Elongatus, sat nitidus, sublevis; prothorace dorso longitudinaliter impresso, in impressione bifoveolato ; 
elytris seriatim subtiliter remote punctatis. 
Long. 14-16 millim. 
Hab. Mexico, Tepansacualco (Sa//é). 
Rostrum short and broad, rather densely punctate, a little impressed in front and 
canaliculate in the impression; a small, distinct fovea on the forehead. ‘Thorax 
elongate, a little narrowed in front; an elongate, vague impression on the middle, in 
which are placed two fovee or very large punctures, one in front of the other; each 
side bears a short, irregular impression ; the surface generally is rather dull, and when
