152 TORTRICINA. 



kinson from larvae found in June at Lytham, Lancashire, feeding 

 on the Meadow Sweet (Spircca Ulmarid). 



3. Lceflingiana, Linn. Alis anticis testaceo flavis ; strigulis ochraceis 

 literaque ^ duplici medio costaB rufescentibus ; posticis griseis. 

 3 Exp. al. 8 lin. 



Head and face testaceous yellow. Eyes black, with a velvety ap- 

 pearance. Palpi : above, beneath and between, same colour as the 

 head, somewhat darker at the sides. Antenna straw-colour above, 

 fuscous beneath ; basal joint beneath, straw- colour. Thorax and 

 patagia testaceous yellow, slightly darker in front. Anterior wings 

 glossy testaceous yellow, with ochreous interrupted wavy streaks and 

 reticulations, and slightly leaden-coloured markings on the costal 

 margin; these latter are very varied in intensity and form, but 

 usually assuming the shape of the Greek letter ^; they are two in 

 number, one situated before, the other beyond, the middle, preceded 

 and succeeded by similar-coloured undefined markings ; these costal 

 markings are more or less produced, in different specimens, towards 

 the dorsal margin. Apical scales of a leaden-brown tinge. Cilia 

 dull straw-colour. Posterior wings pale shining grey, clothed with 

 coarse fuscous scales. Marginal scales fuscous, with luteous bases. 

 Cilia straw-colour. Abdomen pale shining grey, the caudal tuft 

 straw-colour. Exp. al. 8-9 lin. 



A common and variable species, in some of its aspects re- 

 sembling D. contaminana, but distinguishable therefrom by the 

 paler ground-colour of the anterior wings, the less distinct re- 

 ticulation, and by the truncate apical margin. The named 

 varieties are D. ectypana, Lceflingiana, and plumbana. 



D. ectypana (Hub. To. t. 30. f. 190) has the markings of the 

 anterior wings nearly obsolete, but most visible on the costa. 



D. L&flingiana : the typical insect as above described. 



D. plumbana has the markings, as the name implies, of a 

 leaden hue, and are broader and more suffused than in D. Loeflin- 

 giana proper. 



The imago appears from June (Haworth says as early as 

 April) to September, in various parts of the country, but more 

 particularly in the south, and within the metropolitan district. 



The pupa is ferruginous brown, and measures 4 lines. 



The larva feeds on Hornbeam, Oak, &c. It is about 6 lines 

 in length, pale green, with black spots; the sides yellowish. 

 Head and shield black ; the latter pale anteriorly. Before 

 assuming the pupa state it spins a dead-white silken web.
