ANCHONUS. 81 
Two specimens. Very like A. verrucosus, but with the rostrum less constricted at 
the base, the prothorax not tuberculate at the sides, the prominences on the disc 
of the elytra stouter and less conical in shape. Larger, broader, and more robust 
than A. spiculosus, with the rostrum distinctly constricted at the base, the prothorax 
quadrinodose, and the elytra with stouter setigerous prominences. 
25. Anchonus spiculosus, sp.n. (Tab. V. figg. 28, 28a, 2.) 
Oblong-ovate, black, the antenne and tarsi rufescent ; the sete very short, scattered, fine, and inconspicuous. 
Rostrum stout, cylindrical, strongly curved, rugosely punctured, smoother at the tip. Prothorax a little 
longer than broad, widest at the middle and narrowing thence to the base and apex, and constricted in 
front; the surface uneven, shining, coarsely, rugosely punctate, the interspaces here and there raised and 
granulate. Elytra convex, ovate; coarsely seriate-punctate, the interstices 2-7 each with a series of 
smooth, shining, conical tubercles, those on 2-5 intermixed with smooth oblong elevations. Femora 
_ coarsely punctate. 
Length 37, breadth 14 millim. (9.) 
Hab. Mexico (Sallé). 
One specimen, not labelled with any definite locality. A very small isolated form, 
distinguishable by the rugosely punctate, shining prothorax, the smooth, conical or 
oblong tubercles on the elytra, and the short, fine, inconspicuous sete. 
26. Anchonus quadrituberculatus, sp.n. (Tab. V. figg. 29, 29a, 2.) 
Oblong-ovate, black, the apex of the rostrum, the antenne and tarsi rufescent; the sete short, erect, and 
scattered. Rostrum stout, curved, slightly thickened towards the base, and there feebly constricted, 
coarsely punctate, the punctuation becoming fine at the tip. Prothorax nearly as long as broad, widest 
a little before the middle, obliquely narrowing thence to the base, and narrowing and constricted imme- 
diately before the apex; the surface irregularly punctate and granulate, except along a narrow space down 
the middle, and with two small shining nodules at the apex, two in a line with them on the middle of the 
disc, and some others near the anterior angles, and two larger and more prominent elevations at the sides 
before the middle ; the flanks closely punctate. Elytra ovate, convex ; seriate-punctate, the interstices 
1-7 each with a scattered series of shining, conical tubercles, which are here and there placed close 
together, so as to form short ridges. 
Length 43, breadth 2 millim. (2.) 
Hab. Guatemaa, Senahu in Vera Paz (Champion). 
One specimen. The chief characters of this insect are the two smooth, prominent 
tubercles on each side of the prothorax before the middle (the margins appearing 
strongly sinuate), and the four smooth, minute, nodiform elevations on its disc, the 
elytral interstices 1-7 each with a series of smooth, conical tubercles, which are here 
and there contiguous. The non-carinate, non-tuberculate rostrum separates it from 
A. verrucosus and A. tuderculirostris; and the basally constricted rostrum, different 
prothoracic sculpture, &c., from A. spiculosus, near which the species seems best 
placed.
