ABRENTODES.—CLZODERES. 51 
5. Abrentodes robustus, sp. n. 
Niger, prothorace senescente, polito ; elytris flavo-variegatis, multisulcatis, sulcis duobus ad suturam impunc- 
tatis, sulcis externis crenato-punctatis, interstitiis haud latis. 
Long. 15 millim. 
Hab. Guatemata, Purula (Champion). 
Head and metarostrum scarcely different in the two sexes, the metarostrum rather 
long, deeply impressed along the middle. Prorostrum of the male short, with a series of 
projections on each side, above, like those existing in Rhaphirhynchus; neck of the head 
very abrupt. Thorax highly polished, moderately broad. Elytra rather short, with 
very regular and deep striation; in the first two striee punctures are scarcely evident, in 
the next they are obscure, but in those more external so distinct as to make the strize 
very conspicuously crenate; the third interstice is yellow for nearly half the length 
posteriorly, the fourth is yellow from the base for three-fourths of the length, the fifth 
has a very short streak behind the middle, the seventh a longer streak behind the 
middle, while the eighth is yellow from behind the shoulder for the greater part of the 
length: there are also a few other more vague yellow marks, The under surface is 
polished and shining, the ventral segments depressed along the middle in the male. 
Both the sexes have deep foveoles on the under surface of the head and metarostrum. 
Two specimens. | 
Although closely allied to A. sulcipennis, I have little doubt this is distinct ; it may be 
distinguished by the deeper, broader strize of the elytra, which, too, are more evidently 
punctured.

Cleoderes, Schénherr, Gen. Cure. i. p. 362 (1833) ; Lacordaire, Gen. Col. vii. p. 440. 
This genus includes only a single South-American species in addition to those found 
in our region.

This insect is readily distinguished from the other species of the genus, so far as the 
male sex is concerned, by the front femora being definitely bidentate: the outer tooth is 
shorter than the inner, and is more widely separated from it than is the small tubercle 
that in some individuals of the other species might be accepted as a tooth, ‘The 
outer yellow line is usually present in only an abbreviated form; this character, and 
the fact that the antenne are more slender at the apex than they are in the other 
species, offer the only means, so far as I see, for distinguishing the females, 
Although we have received C. diserrirostris from only one locality, yet, as there are 
about thirty specimens before me, it seems possible the species may be a good one.
