HETEROMERA. 



texture and are divaricate at apex; legs long, femora of male strongly 

 thickened. 



O. femorata, F. ( ? calopoides, Germ.). Livid-brown, rather pale, 

 with the forehead, sides of thorax, base of abdomen and a ring before 

 apex of femora dark brown or black-brown ; head considerably produced 

 in front, antennae very long and slender; thorax longer than broad, 

 somewhat narrowed behind, closely punctured except on centre of disc, 

 testaceous with the sides broadly black, the black colour often spreading 

 over the greater part of the disc; scutellum light; elytra long, sub- 

 parallel, divaricate at apex, closely punctured, with three or four raised 

 lines 011 each ; legs long, testaceous with the femora more or less 

 infuscate. L. 12-16 mm. 



Male with the posterior femora much thickened and the posterior 

 tibiae strongly curved. 



On ivy bloom and occasionally on sallows; found both in spring and autumn; 

 local, but not rare in many districts; it is nocturnal in its habits, and sometimes 

 comes to sugar placed on trees to attract moths ; Ripley (Surrey), Mickleham, Darenth

NACERDES, Schmidt. 



This is a moderately large and very widely distributed genus, its range 

 extending from Siberia to Madagascar and Brazil ; the species, however, 

 are chiefly found in temperate climates, and only two or three have been 

 described from the New World ; only one of the fifteen European species 

 is found in Britain ; it is a long reddish insect with a black tip to the 

 elytra, and very strongly resembles certain species of Telephones ; it may 

 be known by the 12 jointed antennae of the male; the eyes are 

 oblique and kidney-shaped; the maxillary palpi have the last joint 

 oblong, obliquely truncate at apex, and about as long as the penultimate; 

 the thorax is slightly narrowed behind, and is much narrower at base 

 than elytra, which are long and subparallel ; the posterior femora of the 

 male are not thickened. 



The larva of N. melanura is described and. figured in two positions (viewed from 

 above and sideways) by Schiodte (xi. p. 540, t. xvi. 1 and 2) ; it is seven or eight 

 times as long as broad, and is much narrower in front than behind, to a slight extent 

 resembling some of the larvse of the Buprestidse ; the head and legs alone are cor- 

 neous, and the colour is white with the last-mentioned parts yellowish, and the clypens, 

 mandibles and palpi pale ferruginous ; the head is large, being nearly as broad as the 

 prothorax, which together with the next four segments is uneven and furnished with 

 a hump or knob on the centre of the dorsal surface ; the legs are moderately long ; 

 the remaining abdominal segments are simple and of different lengths, the last being 

 nurrower and without cerci ; all the segments are setose at the sides ; the " pi seterga " 

 and " posterga," or the membranes joining the segments, arc very evident; the larva 

 lives in dead wood, especially oak, and mines galleries
