630 RHYNCHOPHORA. 
Three specimens. Very like the Venezuelan S. pictus, Faust, but with the vestiture 
sparser, the fulvous scales condensed into small spots on the apical declivity (and not 
into a large apical patch) and some irregular markings near the shoulders; the elytral 
interstices feebly convex, and each with a row of very short, erect sete (the alternate 
ones being raised and setose in S. pictus). This last-mentioned character separates 
S. fulvopictus from S. planirostris. 
4, Semnorrhynchus fulvifrons, sp. n. 
Very like S. fulvopictus, but narrower, the upper surface dull, alutaceous; the head thickly clothed with 
fulvous scales in front; the rostrum coarsely, rugosely punctate to the tip; the prothorax more sparsely 
and less coarsely punctate, with a very narrow impunctate space down the middle; the elytra with an 
irregular, v-shaped, fulvous mark on each side at the base and several small whitish spots at the 
commencement of the apical declivity, the alternate interstices somewhat raised; the under surface 
alutaceous, shallowly punctate; the femora unidentate. 
Length 3, breadth 12 millim. (¢.) 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
One specimen. 
GASTEROCERCUS. 
Gasterocercus, Laporte et Brullé, Mém. Soc. Hist. Nat. Paris, iv. p. 198 (1828) ; Schénherr, Gen. 
Cure. iv. p. 249, and viii. 1, p. 875 (part.); Lacordaire, Gen. Col. vii. p. 118 (part.). 
The Tropical-American species referred by Schénherr to this genus, the type of 
which is the European G. depressirostris (Fabr.), will probably have to be separated 
sooner or later. G. propugnator, G. scabrirostris, &c. agree, however, in having a 
short, broad, straight, flattened rostrum, a broad, feebly emarginate, prominent 
mesosternum, a short, blunt, antennal club, and large, descending eyes, and they 
can be retained in Gasterocereus for the present. These forms have the anterior legs 
more or less elongated, and their tarsi hairy, in the males, and the anterior femora 
rather sharply unidentate in both sexes. G. plumipes and G. semicircularis, Boh., 
both of which occur in Central America, must be placed elsewhere.

Pearl Is. (Champion).—Brazit }. 
The two specimens (¢ ) referred to this species agree very nearly with one before 
me from Brazil, except in their smaller size; they have the rostrum more rugose 
at the tip than described by Gyllenhal, but this is, no doubt, a male character. 
The short granulate elevation on the first interstice just behind the scutellum is 
conspicuous, ‘The anterior femora have a sharp tooth. The anterior tarsi are 
clothed with long projecting hairs in the male.
