Phytodecta. | PHYTOPHAGA, 311 
each half is furnished with from six to eight small prominences 
terminating in a seta directed backwards; these appear sometimes to be 
more or less confluent ; the stigmata are small and black. 
About thirty species are contained in the genus, which are chiefly 
confined to the colder portions of the Northern Hemisphere ; only two 
or three, however, have been found in North America; fourteen species 
inhabit Europe, of which five have been recognized as British, but one 
of these, P. afinds, requires further confirmation ; they may be separated 
as follows :— 
I. All the tibie strongly produced into a tooth at apex; 
thorax with a setose tovea at the posterior angles ; elytra 
with fine rows of punctures. (Phytodecta, i. sp.)

II. Anterior tibia not, or scarcely, produced into a tooth at 
apex; thorax with a setose fovea at all the angles; elytra 
with coarse rows of punctures (s.g. Spartophila, Chev.). 
i. Dise of thorax finely punctured ; form shorter, ovate ;

(ditura, F.) 
ii. Dise of thorax coarsely and unevenly punctured ; form 
longer, oblong-oval; sizelarger. . . . . . . . . P. panuipa, LZ. 
P. rufipes, De G. ( fulvipes, Duft.). Oval, convex, shining, upper 
surface red, with the hinder part of head, a bilobed or trilobed, some- 
times oblong, spot at base of thorax, the scutellum and five spots on 
each (which are variable and sometimes partly absent), black; head 
diffusely and rather strongly punctured ; antenne red with apex pitchy, 
short and somewhat thickened towards apex; thorax very transverse 
with sides slightly rounded, almost smooth on dise, coarsely punctured 
at sides, anterior angles acutely produced; elytra with very regular 
fine rows of punctures, interstices finely punctured; under-side black ; 
legs red, femora often more or less infuseate. L. 51-61 mm. 
A variety occurs in which the two hinder black spots on the elytra 
are wanting; this is the C. sexpunctata of Fabricius. 
On hazels, aspens, sallows, &c., in woods; local, but not uncommon where it 
occurs ; London district, Darenth Wood, West Wickham, Claygate, &c.; Brandon, 
Suffolk ; Lords Wood, Southampton; Knowle, near Birmingham ; Bewdley Forest ; 
Burnt Wood, Staffordshire ; Bretby Wood, near Repton ; Langworth Wood, Lincoln ; 
Cumberland ; Scotland, very rare, Solway district, ‘‘ Raehills, Rev. W. Little,”’ 
Murray’s Cat. 
P. viminalis, L. Very like the preceding, but easily distinguished 
by having the head and legs entirely black, and the sculpture of the 
elytra evidently less fine; the anterior angles of the thorax are more 
obtusely produced, and the sides are less rounded, and the black spot 
at the base is, as a rule, less divided ; the spots on the elytra are very 
variable ; in the European catalogue there are eight named varieties 
mentioned. L. 51-7 mm,
