Leioptilus tephradactylus, Hb. 

 (Plate 17. fig. 11.) 



Loc. Huddersfield, Scarborough, Sheffield, Hastings, 

 Folkestone, Lynmouth, Lake-district, Witherslack. 



This species occurs in shady places in woods during 

 July. 



It can be separated from lienigianus by the absence 

 of costal spots and its smaller size. 



The larva feeds in May and June on the golden rod 

 [Solidago virgaurea) — when young mining the stems, 

 afterwards eating holes in the leaves; it pupates sus- 

 pended by the tail from its food-plant. 



The ground-colour of the larva is yellowish green ; 

 head shining, pale yellowish brown, with reddish-brown 

 mandibles and a black spot on each cheek ; dorsal stripe 

 whitish, darker towards the centre ; subdorsal line in- 

 terrupted, yellowish ; tubercles whitish, with tufts of 

 pale hairs ; legs yellowish green. Ent. xv. 106.
