THERSES.—PSEUDOCHORIS. 213 
Hab. Mexico, Jalapa (Hoge). 
A single specimen, apparently a female. 
2. Therses ochripes. 
Elongate, slightly narrowed posteriorly, black; the head, antenns, thorax, and legs fulvous ; elytra greenish- 
eeneous, extremely finely punctured in rows. 
Length 14 line. 
Head impunctate, the clypeus with a few minute punctures only ; antenne fulvous, about two-thirds the length 
of the body, the third and fourth joints equal, the following joints slightly and gradually thickened ; thorax 
twice as broad as long, the sides rounded near the base, strongly narrowed in front, the anterior and 
posterior margins nearly straight, the surface opaque, impunctate, fulvous ; elytra of a brassy-green colour, 
with rows of minute punctures, which are a little more distinct at the sides, the interstices somewhat silky 
in appearance ; legs entirely fulvous. 
Hab. Mexico, Chilpancingo in Guerrero (Hége). 
PSEUDOCHORIS. 
Elongate, subparallel. Eyes entire. Antenne filiform, the terminal joints but slightly thickened, the second 
joint short, the others nearly equal in length. Thorax transverse, the anterior margin nearly straight, 
the sides moderately rounded, the anterior angles not produced. LElytra punctured in rows. Femora 
unarmed. The first joint of the posterior tarsi as long as the following two joints together. Claws 
appendiculate. Prosternum narrowed between the coxe, its base truncate. The anterior margin of the 
prothoracic episterna concave. 
This new genus is proposed for the reception of an insect having the general 
characters of the Iphimeine, without agreeing entirely with any of the genera of 
that group. The filiform, scarcely thickened antenne and the truncate base of the 
prosternum separate Pseudochoris from Choris; the transverse thorax, entire eyes, and 
much shorter metatarsus of the posterior legs from Euphrytus, to which genus, however, 
Pseudochoris is closely allied. 
1. Pseudochoris fulvicollis. (Tab. XL. fig. 18.) 
Obscure greenish-zneous, the head, antenna, thorax, and legs fulvous ; thorax finely punctured; elytra metallic 
green, strongly punctured, the interstices at the sides obsoletely transversely rugose. 
Var. Thorax and elytra obscure seneous. 
Length 2 lines. 
3g. Head rather closely punctured, with a metallic green gloss; palpi fulvous, the terminal joint robust; 
antenne extending to a little beyond the middle of the elytra, fulvous; thorax about one half broader than 
long, scarcely narrowed in front, the sides evenly and moderately rounded, with anarrow margin, the base 
very slightly produced at the middle and accompanied by a deeply impressed line, the anterior angles some- 
what oblique and thickened, the surface finely and rather closely punctured (especially .at the sides), 
fulvous, with a slight metallic gloss; scutellum metallic green, smooth, not broader than long; elytra 
parallel, with a very shallow depression below the base, metallic green or bronze, rather strongly 
punctured in rows, the punctures on the disc finer and more distant than those at the sides, the lateral 
interstices transversely rugose ; legs fulvous, rather robust; the first joint of the anterior tarsi dilated 
in the male, that of the posterior pair not longer than the following two joints together. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (Hl. H. Smith). 
Some specimens, especially females, have the thorax and elytra eneous, and the
