wings appears darker; a fine blackish line precedes the 

 ashy-grey cilia. The underside is nearly of the colour of 

 the upper side. 



In one specimen there is a faint trace of a darker transverse 

 line at three fourths of the length of the wing. 



Five males, taken the beginning of August, at St. Moritz, 

 in the Engadine. (1851.) 



Ennychia cingulalis, Hiibner, Heyden (E. Z. 1861, 

 p. 31). The larva occurs in the middle of September in a 

 wood at Mombach near Mayence, on Salvia pratensis. It 

 generally lives under the leaves which lie flat on the ground, 

 which it gnaws from the under side as far as the upper 

 epidermis, whereby transparent spots appear on the upper 

 side of the leaves. Its web, into which it escapes when dis- 

 turbed, is generally found near one of the Salvia leaves 

 amongst moss and dead leaves; in its neighbourhood there 

 are always rather large heaps of black excrement. 



Rarely the larva, which is not very active, is found on a 

 higher leaf, which is then rather spun together. 



The larva winters in a rather large grey-brown, papery 

 cocoon, and changes to the pupa state in spring. The perfect 

 insect appears at the end of May and beginning of June. 

 (1857.)

 The larva occurs near Frankfort, the middle of October, on 

 Eupatorium Cannabinuni, between tubularly united leaves. 

 It winters in a large, thin, oval, flat, white cocoon, and 

 changes in April to the pupa state. The imago appears at 

 the end of May. (1829.)
