form of the rostrum it belongs to the EZ. vilis group ; but in the sculpture of the thorax 
and the general form it departs widely from the members of that group. ‘The second 
joint of the scape, though not elongate, is distinctly longer than the first. The female 
is considerably broader than the male, and the declivity of the elytra is rather 
longer. 
45. Epicerus sexcostatus, sp. n. (Tab. V. fig. 16.) 
Niger, elytris sordide squamosis ; capite prothoraceque fere denudatis, illo trifoveolato, hoc dorso deplanato et 
in medio impresso ; elytris rude sculpturatis, interstitiis alternis bene clevatis. 
Long. 10-12 millim. 
ITab. Mexico, Parada, Cinco Sefiores (Sai/é). 
Rostrum densely punctate, on each side of the upper face with an elongate depression 
somewhat interrupted near the front; along the middle with a longitudinal depression, 
which is deep and abruptly limited in front, so as to form a sort of fovea; on the fore- 
head with a small, quite distinct fovea. Thorax much narrowed from the base to the 
front, depressed along the middle, and with two punctures in the depression ; the 
surface, like that of the head, is black, but is nevertheless really covered by scales that 
appear to be very delicate and closely adherent to it. Elytra rather broad, each 
with three raised carine, and between each two of these with two series of coarse, 
nearly confluent impressions; covered with a squamosity that looks like dirt. Four 
specimens. 
This is very distinct from the species near which I place it on account of the strong 
carination of the alternate interstices. 
46. Epicerus hegei, sp. n. 
Elongatus, niger, nudus, subopacus ; rostro prothoraceque dense punctatis, punctis minoribus majoribus inter- 
mixtis; elytris ovalibus, seriatim subtiliter punctatis, apice setigeris. 
Long. 12 millim. 
Hab. Mexico, Salazar (£Hége). 
This species, of which only a single worn example of the female sex has been 
obtained, was at first placed by me as aslight variety of & scutellaris; but on exami- 
nation it appears that the scutellum is normal, and not exposed asin £. scuteliaris. 
Moreover, the channel on the posterior part of the thorax is not to be detected, and 
the hind margin of the thorax is conspicuously raised. ‘The elytra, too, in their poste- 
rior part are very distinctly setigerous, the sete being fine, short, quite erect hairs, 
whereas in E. scutellaris only a few short depressed setee can be detected. ‘These 
characters leave no doubt that the two are distinct, notwithstanding their great 
general resemblance.
