surface; the eyes very prominent, between them a broad depressed space. Club of 
the antenne elongate; second joint of the funiculus not longer than the first. ‘Thorax 
elongate, rounded at the sides and narrowed in front, coarsely punctate, squamose, the 
clothing dark on the middle, pallid on the sides. Elytra short, convex, with truncate 
base, striate, the interstices not quite flat, densely covered with overlapping scales, and 
with numerous fine, erect, truncate sete ; from each shoulder there proceeds an irregular 
pallid mark, broken in an angular manner; behind the middle there is an irregular 
pallid transverse fascia, and on the declivous apex two or three small pallid marks. 
Twelve specimens. 
Some examples are smaller and more slender than others, and these are probably

males. 
CLEISTOLOPHUS, gen. nov. 
Scutellum ad apicem processu transverso instructum. Femora anteriora subtus denticulata. 
The insects forming this genus have the facies of the elongate species of Epicerus, but 
they are well distinguished by the two characters given above. ‘The very peculiar form 
of the scutellum is, so far as I know, unique in the Coleoptera: its use is very evident, 
for although the wings are completely rudimentary, the elytra in Cle¢stolophus are not 
soldered, but locked together by the transverse process that is placed on the top of the 
scutellum ; this process can always be seen just behind the base of the elytra, where it 
forms a sort of peninsula, the extreme base of the wing-case extending in front of it on 
each side, but not quite meeting the similar projection from the other wing-case. ‘The 
posterior femora are unarmed, but the anterior pair bear a distinct tooth, and the 
intermediate pair a tubercle beneath. The other characters are the same as in the 
typical forms of the genus Lpicerus. 
1. Cleistolophus subfasciatus, sp. n. 
Oblongo-ovalis, parum elongatus, squamosus, colore variabilis, vel viridescens vel grisescens; rostro brevi, 
apice subattenuato, anterius fere inimpresso ; prothorace transverso. 
Long. 7 millim. 
Hab. Muxico, Playa Vicente, San Andres Tuxtla (Sal/é) ; Guaremaua (coll. Sharp) ; 
Honpuras (Dyson) ; Nicaragua, Chontales (Belt). 
Rostrum distinctly narrowed at the tip, its anterior face rather convex and scarcely 
at all impressed on the middle; a fine channel between the eyes, which are rather 
small and but little convex. ‘Thorax broader than long, the sides nearly straight behind 
the middle, much narrowed in front, the surface densely squamose, with scanty, indi- 
stinct, not coarse punctuation. FElytra not elongate, truncate at the base, with a very 
slight constriction immediately behind the basal margin, densely squamose and bearing 
series of fine punctures.
