clxii Pomeranian Species 



period of flight of the spring brood is the beginning of May, partly 

 even in April. The time of the summer brood has escaped me. 



It is by no means rare round Stettin, among the scattered alders of 

 the extensive meadows by the Oder ; on the alders along the ditches 

 and streams at Eckerberg, at Polchow, Falkenwald, Julo, Vogelsang, 

 Hokendorf, &c. ; indeed it is the commonest species near Stettin. It 

 also occurs at Ueckermtinde. 



15. L. Heegeriella, Z. A species hardly any rarer near Stettin 

 than L. alniella. I was much surprized when I repeatedly bred this 

 species, (at least it appears to me from Zeller's Monograph, that it 

 must be this species). I first found the pupae of the spring brood near 

 Eckerberg, in the autumn of 1848, and obtained the Lithocolletides 

 therefrom in the February, March and April of the following year. 

 About the middle of October, 1849, I found the pupae on oaks at 

 Eckerberg, Polchow, Falkenwald and Julo ; I never met with it at 

 Vogelsang, nor on that side of the Oder. It likewise occurs at Uec- 

 kermtinde, and everywhere frequents oaks, both old and young trees. 

 The period of flight is in the second half of May, especially at the end 

 of that month. The second brood appears together with Cramerella, 

 Amyotella, &c, in the last ten days of August, but is not so plentiful 

 as the first. 



16. L. Cramerella, Fabr., is very common in Pomerania upon oaks, 

 more especially on large trees, from the lower branches of which I 

 collected it; at Falkenwald and Vogelsang it is common; at Polchow 

 scarcer ; at Eckerberg and Julo only singly. In the room I obtained 

 the moth from the beginning of January to the end of February. It 

 occurs at Ueckermtinde also. 



17. L. tenella, Z., also occurs near Stettin, but is very scarce 

 on oaks. 



18. L. emberizaepennella, Bouche, mines the leaves of Lonicera 

 Caprifolium. I found it already in pupa towards the middle of Sep- 

 tember, thus very early in comparison with the other species ; I col- 

 lected it principally in the Polchower ground : it is abundant there, 

 and in the leafy wood near Vogelsang, in moist places, where alone 

 the plant grows. The leaf of the Lonicera is very soft and tender ; 

 the mined abode, which in this species is very large, cannot therefore 

 be made firm by a single fold of the epidermis, as in the oak-miners. 

 The epidermis of the abode, which runs along the mid-rib, is placed 

 by the larva in many strong folds, by which, though in itself of a very 

 delicate blue- green, it appears wrinkled and whitish green. The en- 

 tire leaf gets thereby much bent, and principally from this, one easily
