COYTIERA.—CHORIS. 215 
COYTIERA (p. 126). 
Coytiera fulvipes (p. 126). (Corysthea hégei, Tab. VIL. fig. 3.) 
To the Mexican localities given, add:—Chilpancingo, Tepetlapa, and Soledad, all in 
Guerrero (H. H. Smith), Iguala in Guerrero (Hoge), 
In a single male specimen, obtained at Chilpancingo, the posterior femora are dilated 
into a triangular tooth: the insect in this respect agrees with Huphrytus, although it 
has the prosternum, and also the thorax, differently shaped. The elytra have a more 
or less distinct depression below the base, and they vary in colour from cupreous to 
metallic green or blue. 
The insect figured on Tab. VII. under the name of Corysthea hégei is, as noted on 
p. 154, only a variety of this species. 
3. Coytiera costata. 
Oblong, obscure wncous; the antenne and legs fulvous; thorax very closely and finely punctured; elytra 
geminate-punctate-striate, the interstices longitudinally costate. 
Var, Antenne and legs piceous. 
Length 2 lines. 
Head rather closely punctured, the eyes widely separated, the labrum fulvous; antenne nearly as long as the 
body, filiform, the first joint thickened from the base to the apex, and slightly curved, the second very 
small, the third and fourth joints equal, the following joints slightly longer; thorax transversely 
subquadrate, the sides rounded, equally constricted at the base and apex, the anterior angles slightly 
produced outwards, the surface very closely, evenly, and finely punctured throughout, with or without 
a shallow fovea on each side; scutellum with a few minute punctures; elytra parallel, with seven or 
eight distinctly raised longitudinal coste extending from the base to the apex, the interstices geminate- 
punctate; legs robust, the femora thickened, the tibie bicarinate on each side, clothed with yellowish 
pubescence, the first joint of the posterior tarsi scarcely so long as the following two joints united; claws 
appendiculate ; prosternum slightly narrowed at the middle. 
Hab. Mexico, Chilpancingo and Iguala in Guerrero (Hége). 
Like C. fulvipes, the present species has not the facies of a Coytiera, but it agrees in 
the principal structural characters with that genus. In the single female example 
received, which was obtained at Chilpancingo, the antenne are much shorter than 
in the male (from Iguala), and the terminal joints are much more robust; the elytral 
punctuation is stronger; and the legs are piceous. 
CHORIS. (To follow the genus Coytiera, p. 127.) 
Mevania, Harold, Coleopt. Hefte, xii. p. 82 (1874) (nomen preocc.). 
Choris, Lefévre, Ann. Soc. Ent. Fr. 1877, p. 123. 
The species for which this genus was established are of small size, and prineipally 
distinguished by the transversely-shaped thorax, its rounded margin, and the elongate 
and narrowed prosternum. The Mexican representative described below does not 
agree entirely in its structural characters with Choris, differences being visible in the
