46 PHYTOPHAGA.—SUPPLEMENT. 
tured, the interstices not costate at the apex ; femora robust and incrassate, the intermediate and posterior 
_ tibiee strongly curved. 
Length 4 lines. 
Hab. Mexico, Tapachula in Chiapas (Hége); GuatemMaLa, Zapote (Champion). 
Although there are but two specimens of this species, I am obliged to separate them 
from C. curvipes. They resemble the latter in the incrassate femora and curved tibie, 
but differ in the almost impunctate and smooth thorax, and in the punctuation of © 
the elytra. The head in C. nitidicollis is rather closely punctured on each side; the — 
antenne are coloured as in the allied species, but they have the third and fourth 
joints short and equal (in C. curvipes the fourth joint is longer than the third, and 
both are more slender); the thorax is scarcely constricted at the sides, and has several 
transverse shallow depressions (the transverse rugosities or strigee are entirely absent, 
and very fine punctures are visible only under a strong lens); the elytra are rather 
closely and finely punctured, the punctures here and there arranged in lines, and the 
interstices are not costate, but at the extreme apex they are irregularly rugose; the 
legs resemble those of C. curvipes ; and the prosternum is just visible. 
The specimen from Tapachula seems to be a female with shorter posterior femora ; 
it has the thorax rather more distinctly punctured, but resembles in other respects the 
Guatemalan insect. 
8 (c). Crioceris championi. 
Metallic green ; antenne dark blue; thorax short, almost imperceptibly wrinkled ; elytra distinctly depressed 
below the base, each with a deep lateral fovea, the surface extremely finely punctured, the punctuation 
semi-regular ; femora short, the tibie slightly curved. 
Length 4-5 lines. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
It will only be necessary to point out the differences between this and the preceding 
closely allied species. C. championi is of the same brilliant metallic green colour, but 
differs thus:—The thorax is very short and extremely finely wrinkled (the wrinkling 
only visible under a strong lens); the elytra have a distinct depression below the base 
(which is not visible in the allied species), the lateral fovea is deep and distinct, the 
punctuation is very fine and scarcely arranged in rows, and the interstices are flat, 
without coste or rugosities, but with traces of pubescence; and, lastly, the femora are 
short and but slightly thickened, and the posterior tibie are scarcely curved. The 
prosternum is invisible between the coxe. The male of C. curvipes has strongly 
incrassate and longer posterior femora; in the corresponding sex of C. championi the 
femora do not extend beyond the second abdominal segment.- The abdomen in the 
Jatter has small white tufts, 
Crioceris gemmans (p. 16). 
To the locality Mexico, add:—San Andres, Cordova, Orizaba, Playa Vicente, Sante- 
comapan (Sallé), Atoyac in Vera Cruz (H. H. Smith).
