EPICARUS. 113 
A very distinct species, the clothing being rather setiform than squamiform, and the 
outline peculiar, recalling that of a large Apion. The rostrum is short and broad, 
deeply and broadly impressed in front, with a fovea on the forehead. The thorax is 
but little narrowed in front, and bears numerous large punctures. ‘The elytra are only 
about as broad at the base as the thorax, but become much broader to behind the 
middle, and are also very convex and rounded behind; the punctures of the series are 
unusually definite and distinct though rather small. Two specimens of uncertain sex. 
The setose squamosity is no doubt very readily abraded and it then leaves the surface 
quite bare. 
18. Epiczrus reversus, sp. n. 
Elongatus, ovalis, niger, griseo-squamosus, ad latera et subtus albidus ; rostro profunde angulariter impresso ; 
prothorace parce profunde punctato; elytris seriatim foveolatis. 
Long. 94-12 millim. 
Hab. Mexico, San Andres Tuxtla (Sallé), Teapa in Tabasco (H. H. Smith). 
Rostrum rather short, with a deep angular depression anteriorly, the sides of which 
converge to meet just in front of a well-marked fovea between the eyes; the lateral 
impressions are elongate and extend as far as the insertion of the antenne, being thus 
in front very near to the median depression, and giving the latter somewhat the 
appearance of being limited by a carina on each side anteriorly. The thorax is 
moderately long, subcylindrical, though a little narrowed in front, with only a few 
punctures. Klytra with series of rather large punctures which are moderately 
approximate. Six specimens. 
This insect was named FE. convexus, Schonh., in Sallé’s collection, but the next 
species agrees better with Boheman’s description. . reversus is closely allied to 
E. convexus, however, and differs by the peculiar depression on the rostrum, and also 
by having the thorax less rugose and the punctures on the elytra larger. E. frontere, 
which has a similar depression on the rostrum, is very different in shape.

Epicerus convexus, Boh. in Schonh. Gen. Cure. vi. 2, p. 281°. 
Hab. Mexico1, Juquila, Panistlahuaca, Etla (Sallé), Jalapa, Oaxaca (Hoge). 
The specimens I assign to this species are in all twelve in number, there being only 
two or three from each locality ; they vary a great deal, so as to leave some doubt as 
to their all belonging to one species. Two or three agree satisfactorily with Boheman’s 
description, having only a slight depression on the rostrum, but in others the depres- 
sion is larger. ‘The pallid colour of the sides also varies, and in some specimens is not 
conspicuous, while in others it is nearly pure white, and in one or two is white,
