1. L. roboris, Z. This is very scarce in the entire neighbourhood 

 of Stettin. After I had long in vain sought for it, I bred one speci- 

 men from some pupae which, at the beginning of April, 1848, I had 

 collected in the still leafy, small ash-wood, near Hokendorf, on the 

 right bank of the Oder. 1 have no other Pomeranian specimen. 



2. L. Saportella, Dup., is no rarity in thickly-leaved woody places, 

 especially where fir-trees and others are intermixed. The chief loca- 

 lity for this species is the patch of wood in the Polchower ground, 

 where it frequents the lofty oaks, (Quercus pedunculata) . In that 

 place we collected the pupae in the fallen oak-leaves, quite late in Oc- 

 tober, and these furnished us with an abundant harvest of specimens. 

 Kept in a warm room, the perfect insects appeared through the whole 

 of February; only a few remained until March. The period of flight 

 in the open air is with us from the middle of May till June. 1 have 

 not observed the second brood here, but in the Mark I found it at the 

 end of July and beginning of August. It occurs near Stettin in the 

 Falkenwald forest, at Julo, near Eckerberg, but nowhere so abundant 

 as near Polchow. Near Vogelsang, where there are many of these 

 oaks, it does not occur. 



3. L. Amyotella, Dap. Likewise very sparingly on oaks near Stet- 

 tin, but more abundant at a greater distance. I first found it near 

 Eckerberg, in the middle of October, 1848, as pupae, along with other 

 oak-miners, naturally without being able to distinguish them. On the 

 1st of October, 1849, I found they were yet larvae, as most of the spe- 

 cies of Lithocolletis do not assume the pupa form until the middle of 

 that month. Kept in a warm room, where the white glass-pots stood 

 near the double window, the perfect insect appeared from the middle 

 of January to the end of February. The period of flight, in the open 

 air, also occurs somewhat earlier than that of Saportella. The second 

 brood, which appears more abundant than the first, flies from the
