134 RHYNCHOPHORA. 
(from New Jersey) before me in the slightly coarser puncturing of the prothorax, the 
more coarsely punctured elytral strie, and the convex interstices. 
2. Onychylis setiger, sp. n. 
Oblong-ovate, dull, black, densely clothed with brownish-grey, rather shining, agglutinated scales, the pro- 
thorax with two paler vite: on the disc, and the elytra mottled with whitish towards the sides and 
sometimes with an interrupted fascia towards the apex, the rostrum, antenna, and legs obscure 
ferruginous. Rostrum strongly curved, moderately stout, a little longer than the prothorax, bare, 
shining, sparsely punctate. Prothorax transverse, rounded at the sides, constricted in front, densely, 
rather coarsely punctate. Elytra moderately long, much wider than the prothorax, a little flattened on 
the disc and subparallel towards the base, deeply striate, the punctures of the striae indistinct, the inter- 
stices almost flat and densely reticulate, the alternate ones each with a scattered series of short, fine, 
decumbent, pallid setee. Legs moderately stout; tibie finely denticulate and ciliate within; third tarsal 
joint broad, bilobed. 
Length 3-34, breadth 1} millim. (@.) 
Hab. Mexico, Amula in Guerrero (H. H. Smith). 
Four specimens. ‘This species, to judge from the description, must be nearly allied 
to O. alternans, Lec., from Texas, which also has the alternate elytral interstices 
setigerous; but differs from it in having the prothorax constricted in front and the 
tarsi broader, the third joint of the latter being strongly bilobed. 
3. Onychylis cretatus, sp. n. 
Subovate, rather broad, black, the tip of the rostrum, the antenne, and tarsi ferruginous ; the entire surface, 
the tip of the rostrum excepted, thickly coated with opaque, greyish-white, agglutinated scales, the 
rostrum, prothorax, and legs clothed with short, fine, curled hairs, the elytra with a series of fine, curled 
sete on each of the alternate interstices. Rostrum stout, curved, slightly longer than the prothorax, 
smooth and shining at the tip. Prothorax transverse, rounded at the sides, a little more narrowed in 
front than at the base, with rather prominent ocular lobes ; the surface (beneath the squamosity) dull, 
alutaceous, and excessively minutely punctate. Elytra subcordate, at the base one-half wider than the 
prothorax, the apices a little produced and conjointly rounded; the surface (beneath the squamosity) 
shining, deeply punctate-striate, the interstices narrow, convex, and rugulose, the alternate ones more 
raised than the others and with the setz not very closely placed. Prosternum slightly depressed in the 
middle. 
Length 24, breadth 1§ millim. 
Hab. Mexico, Vera Cruz (/f6ge). 
One specimen. Very like a Tychius, but easily separable therefrom by the hooked 
apices of the tibie, the slender, simple claws, the straight ventral sutures, &c. 
LISSORHOPTRUS. 
Lissorhoptrus, Leconte, Proc. Am. Phil. Soc. xv. p. 183 (1876). 
The species referred to this genus have the rostrum very stout and comparatively 
short; the antennal club smooth and shining for two-thirds of its length (as in the 
European Llmidomorphus); the funiculus 6-jointed; the tibia stout, mucronate, 
and armed with a long hook at the inner apical angle, the intermediate pair strongly
