Galerucella. | PHYTOPHAGA. 329 
these species, and specimens that I have been accustomed to regard as type 
G. sagittarie certainly have the sutural apical angle slightly produced in 
a point, so that I still feel some doubt as to their distinctness, although 
ordinary specimens of the two species certainly look quite different. 
L. 4-5 mm. 
Marshy places; on Lysimachia vulgaris, Hydrocharis morsus-rane, Hypericum 
quadrangulum, &c.; also on rushes ; local, but not uncommon where it occurs, and 
distributed much as the preceding species; it appears to be rarer or rather more local 
in the north of England, and the only Scotch record is Solway district, Dabton Loch, 
Thornhill, near Dumfries, in numbers (Sharp). : 
G. lineola, F. Oblong, subparallel, rather depressed, of a dull 
yellowish-testaceous colour, with the apex of the joints of the antenne, 
the vertex of head, the scutellum, the meso- and metasternum, and the 
abdomen, except apex, black ; in general appearance it much resembles 
the preceding species, from which it may be at once known by its dull 
and much more closely pubescent thorax, somewhat narrower and more 
parallel elytra, and by having the apical sutural angle of the elytra with- 
out a trace of a prolongation; from the two following species it may be 
distinguished by its more elongate and parallel-sided elytra, and by the 
fact that the epipleure cease a little before apex of elytra; varieties 
occur in which the humeral callosity and an obscure black band on each 
elytron are brownish or blackish, but as a rule the elytra are quite im- 
maculate. L. 4-5 mm. 
The sexual characters are much as in the preceding species. 
On willows, especially Salix viminalis, also on alders and hazels; I used to find it 
abundantly in osier beds near Repton, Burton-on-Trent ; it appears, however, to be 
more local than several of the other species; Greenhithe; Woking ; Brentford ; 
Hastings; Portsmouth district ; Glanvilles Wootton; Exeter; Bristol; Swansea ; 
Wicken Fen; Burwell Fen; Cheshire; Ireland, near Waterford (Power), and 
Armagh (Johnson) ; the only Scotch record is “ Raehills, Rev. W. Little,’’? Murray’s 
Cat., and I feel very doubtful as to the Northumberland specimens, as those at first 
recorded were shown by Mr. Crotch to be G. tenella, and Bold quotes the only ones 
he appears to know of as synonymous with G. lythri, which is apparently synonymous 
with G. calmariensis, L. 
G. calmariensis, L., nec F. (lythri, Gyll.; aquatica, Mill.). 
Smaller than the preceding species, from which it may be known by 
having the epipleure of the elytra continued to apex, and the sutural 
apical angles mucronate ; the punctuation of the elytra also is much 
coarser ; from G. tenella it may be distinguished by its larger size, 
more closely pubescent thorax and darker antenne, and also by the 
deeper punctuation of the elytra; the usual colour is testaceous yellow, 
with the vertex, central line of thorax, scutellum, a well-marked longi- 
tudinal band on each elytron, and the breast and abdomen (except apex) 
black ; the antenne are dark with the base red; the colour, however, is 
variable, the elytral bands being sometimes wanting, in which case, 
however, the humeral callosities usually remain dark; the thorax is
