a little more finely punctured, and near the suture are obsoletely rugose 

 transversely ; in the male the antennae are very long, much longer than 

 the hody, and the general form is narrower than in the female, which 

 has much shorter antennae; 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. 3f-5 mm. 



On birch, willow, alder, hazel, &c. ; somewhat local, bat 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 coxae are con- 

 tiguous at apex, and the posterior pair are widely distant ; the tibiae 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 Mack. 



i. Head and thorax dull, more closely punctured, frontal 



tubercles not distinct ; colour lighter L. CAPRE.F., L. 



ii. Head and thorax shining, less closely punctured, 



frontal tubercles distinct, polished and shining; 



colour darker, the suture at least being nearly 



always black L. BUTCRALIS, Thorns. 



II. Thorax rounded at sides, and not angled ; upper sur- 

 face sanguineous L. CKAT.EGI, Forst. 



(sanguineu, F.) 



Zi. capreee, 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 ; antenna' at base and the 

 knees, tibiae, 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, antennae 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. 4-5| mm. 



Male with the first joint of the tarsi, especially of the posterior pair, 

 strongly dilated, the posterior tibiae curved, and the second to the fourth 

 ventral segments of the abdomen pilose in middle.
