130 RHYNCHOPHORA. 
constricted at the base, stout, cylindrical, about as long as the head and prothorax, punctulate, the antenna 
inserted far before the middle; eyes contiguous beneath. Prothorax convex, a little broader than long, 
rounded at the sides, much narrowed in front; closely, finely punctate, with the narrow interspaces 
smooth and shining. Elytra one-half wider than the prothorax, parallel towards the base, with fine, 
sharply-cut striz, the interstices flat, shining, and faintly punctulate. 
Length 3 millim. 
Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). 
One specimen, probably a male. Amongst the species here enumerated, S. tectus 
is distinguishable by its comparatively large size, the very coarse, imbricate squamosity, 
and the conspicuous, coarse, white, decumbent sete of the elytra. 
2. Smicronyx loricatus, sp. n. 
Oblong-ovate, rather narrow, black, the middle of the femora and the tibie: in part rufo-piceous ; the surface 
thickly clothed with coarse, oval, imbricate, white scales, amongst which, except along the narrow white 
median vitta on the prothorax, there are a few pale brownish ones intermixed, and with scattered, curled, 
fine, decumbent sete (these being scarcely visible till the insect is viewed in profile). Rostrum feebly 
constricted at the base, stout, tapering a little towards the tip, about as long as the head and prothorax, 
punctulate, the antenne inserted before the middle. Prothorax convex, broader than long, rounded at 
the sides, slightly narrower in front than at the base, very finely punctate. Elytra nearly one-half wider 
than the prothorax, subparallel towards the base, with fine, sharply-cut striw, the interstices flat, shining, 
and faintly punctulate. : 
Length 2 millim. 
Hab. Mzxico, Amula in Guerrero (H. H. Smith). 
One specimen. Very similar to a Texan insect sent to me by Mr. Wickham under 
the name of S. spurcus, Casey, but narrower and more convex, with coarser, whiter, 
more oblong scales, and a much stouter rostrum. The eyes appear to be contiguous 
beneath. 
3. Smicronyx cataphractus, sp.n. (Tab. VIII. fig. 12.) 
Oblong-ovate, black, densely clothed with intermixed, white and brown, coarse, oval, imbricate scales, the 
white scales forming a median vitta on the prothorax and numerous spots and short streaks on the elytra, 
and with scattered, fine, curled, decumbent seta. Rostrum about as long as the head and prothorax, 
constricted at the base, stout, tapering outwards, rugulose, smooth and shining at the tip, the antenne 
inserted slightly before the middle, the eyes contiguous beneath. Prothorax broader than long, convex, 
rounded at the sides, a little more narrowed in front than at the base, finely punctate. Elytra about 
one-half wider than the prothorax, parallel towards the base, with fine, sharply-cut striw, the interstices 
flat, shining, and finely punctulate. 
Length 2 millim. 
Hab. Guatema.a, San Gerénimo (Champion). 
One specimen, in perfect condition. Slightly broader than S. loricatus, with the 
vestiture denser, and tessellate on the elytra, the scales not quite so coarse and more 
imbricate.
