a little more finely punctured, and near the suture are obsoletely rugose 
transversely ; in the male the antennz are very long, much longer than 
the body, and the general form is narrower than in the female, which 
has much shorter antenne; the head also is broader in the male, and the 
fifth ventral segment of the abdomen is impressed with a fovea in the 
middle. L. 33-5 mm. 
On birch, willow, alder, hazel, &c.; somewhat local, but generally distributed 
throughout the greater part of England ; Scotland, common as far north as the 
Moray district ; it probably occurs commonly in Ireland; it is spread over Europe and 
the northern half of Asia.

This genus seems quite distinct from Adimonia from the fact 
that the anterior coxal cavities are open behind, whereas in the latter 
genus they are closed; from Galerucella it may be known by the 
glabrous upper surface of its members ; the intermediate coxe are con- 
tiguous at apex, and the posterior pair are widely distant ; the tibiz are 
simple and the claws of the tarsi dentate ; of the eight European species 
three are found in Britain; they may be distinguished as follows :— 
I. Thorax produced into a more or less distinct angle in 
middle of sides; upper surface dirty testaceous, fus- 
cous, or black. 
i. Head and thorax dull, more closely punctured, frontal 
tubercles not distinct ; colour lighter . . L. CAPRER, L. 
ii. Head and thorax shining, less closely punctured, 
frontal tubercles distinct, polished and shining; 
colour darker, the suture at least iia iad 
always black. . . . . L.sururatis, Thoms. 
II. Thorax rounded at sides, dl not angled ; ; upper sur-

(sanguinea, F.) 
ZL. caprese, L. Oblong, rather convex, black, with the thorax and 
elytra yellowish-testaceous or fusco-testaceous, the former being marked 
with black, and sometimes entirely dark; antenne at base and the 
knees, tibia, and tarsi usually more or less testaceous; upper surface 
very scantily pubescent, rather shining ; forehead closely and finely and 
somewhat rugosely punctured behind, with the frontal tubercles not 
distinct, antennz moderately long, with the third joint more than twice 
as long as the second ; thorax transverse, angled in middle of sides, 
with a central furrow and a broad fovea on each side, strongly and 
coarsely punctured; elytra broader at base than thorax, slightly widened 
behind, with the shoulders rounded, and with rather strong and almost 
smooth humeral callosities, rather closely, coarsely, and ‘deeply punc- 
tured; legs rather stout. L. 4-55 mm. 
Male with the first joint of the tarsi, especially of the posterior pair, 
strongly dilated, the posterior tibie curved, and the second to the fourth 
ventral segments of the abdomen pilose in middle.
