delicately tinted with green. Such examples were labelled Hpicwrus marginalis, 
Chevr., in Sallé’s collection. 
A typical example of E. convexus, communicated from Schénherr’s collection by 
Dr. Aurivillius, is rather larger and more elongate than any of our series, and has the 
rostrum still less distinctly impressed ; but I consider it to be only an extreme form of 
the same species as our series. 
20. Epicerus sturmi, sp. n. 
Minus elongatus, ovalis, convexus, niger, griseo-squamosus, lateribus corporeque inferins albidis; rostro 
profunde impresso ; prothorace conico, subsequali; elytris seriatim remote punctatis. 
Long. 93 millim. 
Hab. Mexico (Sallé). 
This species is allied to E. convexus and E. reversus, but is considerably shorter in 
form; the rostrum is short, broadly and deeply impressed in front, with a minute 
fovea between the eyes. The thorax is gradually narrowed from the base to the front, 
with a coarse but indistinct punctuation, and a feeble longitudinal depression, not 
extending to the base, on the middle. The elytra have regular series of remote 
punctures, distinct at the base but extremely minute behind; the squamosity is rather 
irregularly distributed, so as to give a slight appearance of two rather darker fascize 
across the middle. 
Of E. sturmi we have obtained only two old examples, without special locality, from 
Sallé’s collection; one of them was formerly in Sturm’s collection and is labelled 
“ Barynotus obliquefasciatus, mihi,” in that naturalist’s writing. It is not very likely 
to be mistaken for any other of our species except 2. reversus, which is of much more 
elongate form. LE. frontere has also a deep impression on the front of the rostrum, 
but it is a larger and broader insect, with less conical, more coarsely sculptured thorax. 
The two specimens of H. s¢twrmi are no doubt of the female sex. 
21. Epicerus championi, sp.n. (Tab. V. fig. 7.) 
Angustulus, griseo-squamosus; prothorace inequali, fortiter subobsolete punctato; elytris transversim 
subundulatim impressis. 
Long. 9 millim. 
Hab. GuatEMALA, San Geronimo (Champion). 
Rostrum rather short, punctate and squamose, impressed along the middle and 
foveolate at the summit of the impression; lateral impressions broad and placed much 
on the front aspect. ‘Thorax subconical, but with a slight constriction at the sides 
behind; the surface with coarse, very vague, rather regularly distributed impressions. 
Elytra slightly constricted at the base, with series of impressions that are connected 
trausversely so as to form undulatory grooves. The suture of the elytra is in the 
female a little more prominent at the commencement of the apical declivity.
