Galerucella.'] PHYTOPHACLA. 327 



retained the latter name for A. tanaceti and (xlandica, and havo adopted 

 Crotch's name for the present genus (in the Munich catalogue it is 

 regarded as including Lochmaea) ; thus constituted it contains about 

 eighty species, which are very widely distributed, representatives 

 occurring in Siberia, Madagascar, and the Cape of Good Hope, the 

 Australian region, &c., as well as in the intervening districts ; ten 

 species of Galerucella proper are found in Europe, of which six are 

 inhabitants of Britain ; several authors separate G. viburni as a distinct 

 genus (Trirrhahda, Lee.), on account of the projecting genae and long 

 and stout mandibles; Thomson includes Trirrhabda, Lochmaa, and 

 Galerucella, under one genus, Galeruca, while Horn and others, while 

 accepting either one or two of these genera as separate, abolish the 

 name Galerucella altogether ; the members of the genus Galerucella, as 

 here constituted, may be known by having the anterior coxal cavities 

 open behind, the third joint of the antennae distinctly longer than the 

 fourth, and the body thickly pubescent ; the thorax is finely margined at 

 ba~e, and the epipleurae 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 genre and long and stout 

 mandibles ; femora comparatively thick, with the anterior 

 pair somewhat more slender than the others (s.g. 



Trirrhabda, Lee. ; Pyrrhalta, Joann.) G. VIBUBSI, Pnyk. 



II. Head short, with narrow gense and rather short mandibles ; 

 femora comparatively slender (Galerucella, i. sp.). 



i. Epipleurae of elytra ceasing shortly before apex. 



1. Apical edge of elytra sinuate, so that the sutural 

 angle is produced into a short point ; intermediate coxa) 



plainly separated G. NYMPHJEJE, L. 



2. Sutural apical angle of elytra entirely rounded, or 

 scarcely produced ; intermediate coxaj almost con- 

 tiguous. 



A. Thorax shining, scarcely pubescent G. SAOITTARIJE, Qyll. 



(aqttatica, Fourc.) 



B. Thorax dull, thickly pubescent G. LINEOLA, /'. 



ii. Epipleurae of elytra continued to apex, with the sutural 



apical angle produced. 



1. Size larger, thorax thickly pubescent ; antenna 

 darker ; elytra, as a rule, with a well-defined longi- 

 tudinal daik band on each U. CALMAKIEXSIS, /.. 



2. Size smaller ; thorax scarcely pubescent ; antenna) 

 lighter ; elytra often obscurely infuscate on disc, but 



without a well-defined dark band G. TEXKLI.A, /.. 



O. viburni, Payk. Oblong-oval, convex, dull, clothed with very 

 thick golden grey pubescence, very finely punctured, of a fuscous tes- 

 taceous colour or brownish, with the head, thorax, and a patch near each 

 shoulder lighter, and a spot on the vertex of head, as well as the margins
