exists. The observations referred to already (antea, 

 p. 26) show clearly that complete parthenogenesis 

 occurs with it. 



Its nearest ally is E. umbratica, KL, which agrees 

 with it in the form of the antennse, head and neuration ; 

 but it has the vertex and thorax unpunctured, and 

 wants the red on the thorax. 



European distribution : Sweden, Germany, Holland, 

 France, Switzerland, Tyrol, Hungary, Russia.

Black, shining ; head covered with a microscopic down; the anterior 

 tibis8 in front, the posterior with a broad basal band, calcaria and the 

 half of the metatarsus of the posterior tarsi, white. Wings smoky, 

 hyaline at the apex. 



The has the antennse longer and more thickened towards the apex, 

 the third joint is thickened at the apex. 



Length 2 3 lines. 



Easily known from all the species by the smoky 

 wings, hyaline at the apex. 



Very common, appearing in June and August. The 

 larva is found in July and again in August and Sep- 

 tember on the lower surface of the leaves of the birch, 

 oak, willow and lime. 



The eggs are laid on the under side of the leaf 

 embedded in the epidermis, a hole being left when the 

 larva has left the egg. When young the larva is 

 pale, very shining, and covered with a glistening 

 varnish. The body is very transparent, so that the 

 workings of the internal organs can be seen through
