CARL VON HEYDEN. 19 



The pupa is not enclosed in a cocoon, but is fastened by 

 some web attached to the last segment to a leaf or stem, and 

 the imago appears in the middle of June. (1858.) 



Gelechia Hippophaella, Schrank, Heyden (E. Z. 

 1865, p. 379). I found the larvae at Ragatz on Sippophae 

 Rhamnoides in the middle of August, 1851, and in the 

 middle of September, 1862. The perfect insects appeared in 

 the middle of September, and in the first half of October. 

 (1851.) 



Gelechia pinguinella, Tr., Heyden (E. Z. 1860, 

 p. 120). The larva is in this neighbourhood very abundant 

 in May on poplars (^Populus nigra and pyraviidalis) 

 between united leaves. It changes to the pupa state in the 

 middle of June, generally gregariously under loose bark, 

 beneath a grey web. The perfect insect appears in the 

 middle of July. One finds it abundantly on the trunks of 

 the poplars, running about quickly. (1822.) 



Gelechia acuminatella, Sircom, Heyden (E.Z. 1862, 

 p. 360) {G. palustrella, Heyden olim). I found the larvae 

 in October in meadows at Offenbach. It mines large 

 irregular spaces along the mid-rib of the leaves of Carduus 

 palustriSf and changes to pupa in an oval earth-cocoon, 

 from which the perfect insect makes its appearance at the 

 end of April. (1840.) 



Gelechia Brahmiella, n. sp., Heyden (E. Z. 1862, 

 ry. 175).
