RHINOTMETUS.—PHYSIMERUS. 321 
Head produced in front, finely granulate, sparingly pubescent, the frontal tubercles obsolete, the clypéus -with 
a distinct central ridge; the antenns long, entirely fulvous, joints 1-10 (the second excepted) of nearly 
equal length, the apical one more elongate and pointed ; thorax subquadrate, the sides straight, obsoletely 
angulate before the middle, and slightly narrowed in front, the surface pale fulvous, clothed with silvery- 
grey pubescence, not visibly sculptured; scutellum very small; elytra broader than the thorax at the 
base, and darker in colour, punctate-striate, the punctures not very closely placed, the interstices slightly 
costate ; below and the legs pale fulvous. 
Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). 
Allied to R. canescens, but smaller, and with the pubescence silvery instead of 
golden-yellow. One specimen. | 
7. Rhinotmetus minutus. 
Narrowly elongate, fulvous; the entenne with thickened terminal joints; thorax finely rugose, scarcely 
pubescent ; elytra shining, sparingly pubescent, punctate-striate anteriorly only. 
Length 13 line. . 
Head finely rugose, not longer than broad, the frontal elevations indistinct ; antennee fulvous, scarcely extending 
to the middle of the elytra, all the joints of nearly equal length, the fifth and following ones gradually (the 
terminal joints rather considerably) thickened; thorax a little longer than broad, slightly constricted 
_ behind, the sides subangulate before the middle, the anterior angles tuberculiform, the surface rather 
flat, finely rugose, dark fulvous, sparingly clothed with very short yellowish pubescence; elytra with a 
distinct. depression below the base, punctate-striate to the middle, the punctures indistinct beyond, the 
surface shining, fulvous, very sparingly covered with yellowish hairs ; legs fulvous, the tarsi nearly black ; 
claws appendiculate. . 
Hab. Mexico, Orizaba (Sallé, H. H.. Smith). 
_ A small and narrow species, distinguished by the non-produced head, the thickened 
antenne, and the shining and only anteriorly punctured elytra. Notwithstanding the. 
appendiculate claws, R. minutus seems to me to belong to the present genus. Two 
specimens. | 
PHYSIMERUS (p. 459). 
Physimerus pygmeus (p. 462). 
To the locality given, add:—Mexico, Atoyac in Vera Cruz, Teapa in Tabasco 
(i. H. Smith). 
Some of the Mexican specimens are paler than those obtained in Chiriqui; wae 
have the elytral spots scarcely perceptible, and the antennz almost entirely pale. 
14. Physimerus elongatulus. 
Obscure fulvous, opaque, pubescent; thorax broader than long; elytra finely punctate-striate, the suture 
obscure fuscous; the posterior femora with an obscure spot at the apex. 
Length 14 line. oO 
Head not visibly punctured, clothed with greyish pubescence; palpi with the penultimate joint slightly 
thickened ; antenne nearly two thirds the length of the body, entirely fulvous, the second joint thicker 
but scarcely shorter than the following one, the fourth and fifth joints a little longer, the others very 
gradually thickened and shorter; thorax about one half broader than long, the sides straight, the surface 
somewhat depressed on the disc, closely covered with short yellowish pubescence, entirely obscuring the
