where the Tmpatiens grows, and particularly abundantly in 

 the Black Forest. Herrich-Schaffer has described and 

 figured the different varieties under the name of P, Sey- 

 deniana. 



Grapholitha Vacciniana, Zell., Heyden (E. Z. 1865, 

 p. 101). I found the larvae in great plenty on hedges of 

 barberry {Berheris vulgaris), near Speyer. It generally 

 spins the leaves flatly one upon another and gnaws them 

 much, so that the hedges have often quite a brown appear- 

 ance. At the middle of September the larva quits its abode, 

 and forms a fine, oval, white cocoon, in which to undergo its 

 change to the pupa state. 



The imago appeared in-doors in the middle of April. 

 (1861.) 



Rhopobota n^vana, Hb., Heyden (E. Z. 1865, p. 

 101). I found the larva in June and the beginning of July 

 very abundant in the Black Forest, especially at Baden- 

 Baden, Rippoldsau and Badenweiler on holly {Ilex aqui- 

 folium). It lives beneath a leaf which has been bitten off, 

 which is fastened by a few webs to the upper surface of a 

 green leaf, both which are gnawed by the larva. In a slight 

 whitish cocoon it changes to the pupa state between the 

 leaves, or on the earth. The perfect insect appears at the 

 end of July, or the beginning of August. 



Although the larva has already been described by 

 Treitschke and others, I conceive this additional description 

 to be not altogether superfluous. (1856.)
