retained the latter name for A. tanaceté and elandica, and have adopted 
Crotch’s name for the present genus (in the Munich catalogue it is 
regarded as including Lochmea) ; thus constituted it contains about 
eighty species, which are very widely distributed, representatives 
occurring in Siberia, Madagascar, and the Cape of Good Hope, the 
aiustralian region, &c., as well as in the intervening districts ; ten 
species of G'alerucella proper are found in Europe, of which six are 
inhabitants of Britain; several authors separate G. viburni as a distinct 
genus (Z'rirrhabda, Lec.), on account of the projecting gene and long 
and stout mandibles; Thomson includes Trirrhabda, Lochmea, and 
Galerucella under one genus, Galeruca, while Horn and others, while 
accepting either one or two of these gemera as separate, abolish the 
name (ralerucella altogether ; the members of the genus Galerucella, as 
here constituted, may be known by having the auterior coxal cavities 
open behind, the third joint of the antennze distinctly longer than the 
fourth, and the body thickly pubescent ; the thorax is finely margined at 
base, and the epipleure of the elytra are continued-almost or quite to the 
sutural angle; the legs are glabrous on their external margin, and the 
claws are bifid, or armed with a small sharp tooth ; the colour is usually 
dull testaceous or yellowish, sometimes fuscous brown or almost black. 
The British species may be distinguished as follows:-— 
I. Head rather long, with projecting genz and long and stout 
mandibles ; femora comparatively thick, with the anterior 
pair somewhat more slender than the others (s.g. 
Trirrhabda, Lec.; Pyrrhalta,Joann.) . .... . . G.z VIBURNI, Payk. 
II. Head short, with narrow gene and rather short mandibles ; 
femora comparatively slender (Galerucella, i. sp.). 
i. Epipleura of elytra ceasing shortly before apex. 
1. Apical edge of elytra sinuate, so that the sutural 
angle is produced intoa short point ; intermediate coxze

2. Sutural apical angle of elytra entirely rounded, or 
scarcely produced ; intermediate cox almost con- 
tiguous.
