50 RHYNCHOPHORA. 
Prorostrum of male not armed above with any definite prominences, and with only 
obscure traces of divergent carine; metarostrum sulcate ; head rather long and narrow ; 
antenne moderately long. ‘Thorax highly polished; not at all flat, moderately large, 
without ruge or sculpture. Elytra with three rather deep strie having scarcely 
any trace of sculpture next the suture, outside this with a fourth stria, which is quite 
shallow in the middle, and there very distinctly punctate, outside this with another 
groove still more broadly interrupted in the middle; marked with yellow longitu- 
dinally, in a somewhat vague and apparently variable manner; without any trace of 
tooth at the apex. Base of the abdomen of the male extremely slightly depressed along 
the middle. Under surface of the metarostrum with a few serial foveoles in each sex. 
We have received one example only from each locality. ‘They indicate that this 
very obscure species is more than usually variable. The resemblance to fhaphi- 
rhynchus in the male rostrum and form of the antenne is quite evident, though the 
general facies is more that of some of the “ Brenthides vrais” than is the case with 
A, auratus. 
4, Abrentodes sulcipennis, sp. n. (Tab. II. fig. 16, ¢.) 
Nitidus, niger, prothorace vix subsnescente; elytris flavo-lineatis, multisulcatis, sulcis haud perspicue punc- 
tatis. 
Long. 8-15 millim. 
Hab. Guatemata, Cerro Zunil (Champion). 
Antenne rather short, the outer half or more well set with sete. Prorostrum very 
polished, rather stout, quite straight; metarostrum and head highly polished, the 
former quite short, with a deep depression. ‘Thorax rather short and broad, much 
rounded at the sides, very highly polished. Elytra with numerous deep and regular 
strie, which are not distinctly punctate, though, viewed a little obliquely laterally, 
the interstices are seen to be crenate; they are marked with elongate yellow marks, 
the interstices on which these are placed being considerably broader than the others ; 
the third interstice is yellow for only one-third or less of the length, the part so_ 
coloured being that before the apex; the fourth interstice is yellow from the base to 
beyond the middle, where it forms a splice, or overlap, with the yellow of the third 
interstice; the fifth interstice is yellow only at the basal margin, the eighth has a long 
streak from the shoulder to behind the middle, and there is avery short yellow mark on 
the seventh just where the yellow of the eighth interstice ends. Apex of metasternum 
with a well-marked round fovea. Underside of the head and metarostrum with a few 
large foveoles. 
Three specimens. 
Although similar to A. pusillus, this species may be readily distinguished by the 
sculpture of the elytra. The prorostrum in the male is short, and has a few minute 
asperities on each side on the upper surface.
