84 RHYNCHOPHORA. 
sinuously narrowed behind; the surface very uneven, coarsely, rugosely punctate, with the narrow inter- 
spaces here and there sinuously raised and shining, the disc with a prominent, shining, abbreviated 
median carina. Elytra short-ovate, of the same width at the base as the prothorax, but at the middle 
much wider than it; seriate-punctate, the interstices 3, 5, and 7 each with a row of conspicuous, smooth, 
shining tubercles. Beneath coarsely punctate. 
Length 3, breadth 13 millim. (<¢.) 
Hab. Guatrmata, Las Mercedes, Pacific slope (Champion). 
One specimen. Recognizable by the tuberculate alternate elytral interstices, the 
coarsely punctured, uneven prothorax, which is deeply constricted in front and con- 
spicuously carinate, and the long elytral sete. 
33. Anchonus nodulosus, sp. n. (Tab. VI. figg. 6, 6a, 2.) 
Obovate, black, the antenne and tarsi obscurely rufescent; the sete abundant, very short, coarse. Rostrum 
curved, stout, cylindrical, feebly constricted at the base, finely, not closely seriate-punctate ; the apical 
portion short and considerably dilated in the ¢, and longer, narrow, and cylindrical in the 9. Pro- 
thorax transverse, somewhat flattened on the disc, arcuately dilated at the sides a little before the middle, 
rapidly narrowing thence to the base, and narrowing and strongly, abruptly constricted in front; the 
entire surface closely, coarsely punctate, with the interspaces opaque. LElytra short-ovate; seriate- 
punctate, the interstices 2-6 each with a series of oblong, prominent, setigerous tubercles, 7 also 
tuberculate. 
Length 33-44, breadth 2-21 millim. (¢ 2.) 
Hab. Panama, Bugaba (Champion). 
Four specimens, one only in clean condition. The prothorax in this insect is shaped 
very much as in A. crinitus, except that it is flatter on the disc and has the interspaces 
between the punctures opaque (instead of shining). The elytra are conspicuously 
nodose. The setosity of the upper surface is very short, coarse, and abundant, not 
nearly so long as in A. crinitus. The sculpture of the prothorax is similar to that of 
A. ericius. 
34. Anchonus puncticollis, sp. n. 
Obovate, black, the tarsi and antennz obscurely rufescent, thickly coated with an earthy incrustation; the 
sete rather long and coarse on the elytra, shorter elsewhere. Rostrum (¢) stout, curved, slightly 
thickened towards the base, and there feebly constricted, closely seriate-punctate, (2) more thickened 
towards the base. Prothorax transverse, moderately convex, the sides rounded at the middle and 
converging thence to the base and apex, feebly constricted in front; the entire surface closely, uniformly 
punctate. LHlytra short-ovate, at the base a little wider than the prothorax; seriate-punctate, the 
interstices 3 and 5 each with a scattered series of prominent oblong tubercles, 4, 6, and 7 obsoletely 
tuberculate. 
Length 4, breadth 2-2, millim. (¢ @.) 
Hab. Guatemata, Las Mercedes, Pacific slope (Champion). 
Three specimens. In this species the prothorax is closely, uniformly punctate, and 
rounded at the sides, the larger tubercles on the elytra are confined to the third and 
fifth interstices, the elytral sete are coarse and moderately long, and the rostrum in 
the female is distinctly thickened towards the base.
