80 RHYNCHOPHORA. 
ridge at the base of the third and fifth interstices, and the elytra themselves area little 
more elongate than in the two other examples seen. The eighth joint of the funiculus 
is transverse, and a good deal wider than the seventh. From dA. sal/@i it may be 
distinguished by its more elongate shape, the relatively longer prothorax, and the 
somewhat numerous tubercles on the second elytral interstice towards the apex, these 
being subequal in size. ahreus’s type is figured. 
23. Anchonus oblongus, sp. n. (Tab. V. fig. 26, 26 a, 2.) 
Oblong-ovate, nigro-piceous or black, the antenne and tarsi obscurely rufescent ; the sete coarse, rather short, 
and scattered. Rostrum stout, curved, slightly thickened towards the base, and there feebly constricted, 
closely punctate throughout, the punctuation coarse, but becoming finer at the tip. Prothorax a little 
broader than long, somewhat flattened on the disc, widest at the middle, gradually narrowing thence to 
the base, and narrowing and constricted in front; the surface coarsely, closely punctate, except along 
a narrow, smooth, somewhat convex space down the middle and on an irregular sinuous flattened space 
midway between this and the margin, the interspaces between the punctures dull and here and there 
obliquely or sinuously raised, in one specimen faintly granulate, the sete showing a tendency to form two 
fascicles at the apex and two on the middle of the disc. Elytra oblong-ovate, convex, of the same width 
at the base as the prothorax ; coarsely seriate-punctate, the interstices 2-7 each with a series of oblong 
or rounded setigerous tubercles, those at the base of 3 and 5 cariniform, the suture also tuberculate 
beyond the middle. Femora coarsely rugosely punctate. 
Length 5-54, breadth 2-24 millim. (@.) 
Hab. Guatemaua, Capetillo (Champion). 
Two specimens, one in perfectly clean condition. Very like A. penictllatus, but 
more elongate, the prothorax coarsely, closely punctate, except down the middle and 
along a narrow space on either side of it (instead of being sparsely granulate), the sete 
much shorter, and not forming conspicuous fascicles on the prothorax. ‘The narrower 
and more elongate form, the irregularly punctured prothorax, the sides of which are 
less rounded and the disc without prominent fascicles, and the slightly constricted, 
closely punctured rostrum separate this species from A. cirratus(?). A specimen ( ¢ ) 
from San Gerénimo may also belong here ; but it has longer sete, and the elytra are 
here and there minutely granulate, both on the flattened and on the elevated portions 
of the surface. 
24. Anchonus brevipennis, sp.n. (Tab. V. figg. 27, 27 4, 2 .) 
Obovate, black, the antennee and tarsi obscurely rufescent; the sete very short, but coarse, and arranged in © 
fascicles on the more elevated portions of the surface. Rostrum curved, stout, cylindrical, slightly 
constricted at the base, closely seriate-punctate, with the interspaces longitudinally wrinkled, the apical 
portion densely punctured in both sexes. Prothorax about as long as broad, rounded at the sides, 
narrowed and constricted in front and narrowed behind; the surface uneven, closely, coarsely punctate, 
shallowly suleate down the middle, and binodose at the apex and on the middle of the disc. Elytra 
convex, ovate, comparatively short ; seriate-punctate, the interstices 2-6 each with a scattered series of 
prominent, oblong, setigerous tubercles, 7 with small conical elevations. 
Length 4-43, breadth 2-21, millim. (¢ 2.) 
Hab. Mexico (Sal/é).
