264 RHYNCHOPHORA. 
inserted at about the basal third. Prothorax broad, transverse, much narrowed and constricted in front, 
the sides rounded anteriorly and parallel behind ; closely, finely punctate. Elytra subtriangular, finely 
punctate-striate, the interstices flat and asperato-punctate. Beneath densely punctate. Prosternum 
armed with two moderately long, strongly sinuate spines—which. are curved upward at the tip and 
dilated and concave at the base within,—and with a deep transverse subapical fovea, and a smaller fovea 
on each side of it, the space behind the central oue smooth and tumid. Anterior tibie set with long 
hairs along their inner edge, the anterior tarsi also with long projecting hairs. 
Length 54, breadth 22 millim. (¢.) 
Hab. Guatemata, Tamahu in Vera Paz (Champion). 
One male. Larger and more elongate than G. rectispinis, the prothorax with the 
sides parallel behind and more rounded anteriorly, the elytra with a single transverse 
dark patch at the sides and indications of a faint spot near the apex, the prosternal 
spines of the male narrowly separated at the base and peculiarly-shaped, the anterior 
tibie and tarsi hairy in this sex. G. sinuatispinis has somewhat the facies of G. perus. 
5. Gereeus bipustulatus, sp. n. (Tab. XIV. figg. 23, 234, b, 6.) 
Ovate, black, the antenne and the tips of the tarsi obscure ferruginous; densely clothed above and beneath 
with whitish or brownish-white scales, those on the prothorax radiating from the median line, the elytra 
each with a sharply-defined, transverse, sinuous, black patch at the middle of the disc extending inward 
to the third stria; the prothorax, elytra, and under surface densely, finely punctate. Head finely 
punctate, foveate between the eyes; rostrum rather stout, strongly arcuate, a little shorter than the 
elytra, closely striate-punctate in the ¢, the apical half much smoother in the 9, the antenne inserted 
at about the middle. Prothorax transverse, rounded at the sides anteriorly, much narrowed in front. 
Elytra finely striate. Legs short. 
3. Prosternum shallowly sulcate, and armed with two short conical spines; anterior tibie with a short 
triangular tooth on the inner edge at about the middle. 
Length 33-4,1,, breadth 2-2} millim. (¢ 9.) 
Hab. Mexico (coll. Solari), Jalapa (Hége), Teapa (H. H. Smith); Nicaraeva, 
Chontales (Janson). 
We have received seven specimens of this well-marked species. The vestiture, 
which is usually white or paler beneath, is so dense as to hide the sculpture, and the 
elytra have each a transverse, sinuous, sharply-defined black patch on the outer part of 
the disc at about the middle. The male has short prosternal spines and toothed 
anterior tibie. 
6. Gereus podagrosus, sp.n. (Tab. XIV. figg. 24, 24a, 4, 3.) 
Subrhomboidal, black, the antenne sometimes in part ferruginous, the elytra shining ; thickly clothed above 
and beneath with rather coarse, narrow, flavo-cinereous or cinereous scales, which on the prothorax are 
transversely arranged, the elytra each with two black spots on the outer part of the disc—one, trans- 
verse, just before the middle, the other, oblique, near the apex. Head closely punctate, transversely 
grooved between the eyes ; rostrum arcuate, long and very slender, slightly thickened at the base, finely 
striate-punctate, smoother and longer in the 9, the antenne inserted near the middle in the ¢ , and at. 
about the basal third in the 2. Prothorax transverse, rounded at the sides anteriorly, much narrowed 
in front ; densely punctate, the punctures rounded and separate one from another, Elytra subtriangular, 
narrowly punctate-striate, the interstices flat and asperato-punctate. Beneath closely punctate. 
Prosternum with a smooth tranverse subapical excavation.
