CARL VON HEYDEN. 13 



wing-sheaths. In June, I visited the locality where I had 

 found the cases, but could find none, since, doubtless, in 

 order to undergo their transformation, they had concealed 

 themselves amongst the stones. 



That the larva does not feed on Parietaria officinalis is 

 certain, as this plant does not occur in the neighbourhood. 



My imago agrees quite well with Herrich-SchafFer's de- 

 scription and figure, but it varies much in the size of the 

 dark spots on the anterior wings. In the living specimens 

 the abdomen is yellow. The females I had pinned, before 

 dying deposited eggs with much wool. (1860.) 



Note (E. Z., 1865, p. 106).— The described Tinea is the 

 Parieta7nella of Bruand. The Tinea nigripunctella of 

 Haworth is a different species, hitherto only found in 

 England. 



Tinea argentimaculella, Stainton, Heyden (E. Z. 

 1863, p. 106). I found the larva, at the beginning of June, 

 on walls at Jugenheim, on the Bergstrasse. It lives on 

 mealy, grey-green lichen dust, in delicate, tubular, rounded, 

 serpentine galleries, often an inch in length, which lie on the 

 stones, are of the colour of the lichen, and are covered with 

 its mealy substance. The above-mentioned lichen dust is the 

 young form of a Cladonia, 



In the middle of June it severs a little piece from the 

 end of its tube, rather larger than a millet-grain, and rather 

 pointed at one end, in order to undergo its transformation ; 

 and in this it changes to the pupa state in a rather firm 

 paper-like cocoon. 



The moth made its appearance at the end of June and 

 beginning of July. (1862.)
