﻿54 [August, 



out from the dry moss. I also found here the curious case-bearer, 

 whose case consists of an old hollow piece of stem, in which it can turn 

 round with the greatest ease, and use the hind end of its case as the 

 front. As no Calluna grows here, the larva, if that be its principal 

 food, must also eat other plants. In order to see to what kind of plant 

 it would betake itself, I watched it whilst it was crawling about on the 

 ground amongst the plants and their fragments ; it moved with a hur- 

 ried, tremulous, almost nervous motion of the thin anterior portion of 

 the body. But it did not appear to be seeking any nourishment, 

 so I could form no conclusion as to its food plant, and I allowed it to 

 retain its liberty. 



Before sunset it became calm, but cold; hence the Lepidoptera 

 came out now readily, but flew dull and heavily. Not unfrequently 

 Nyctegretis achatinella got up from amongst Artemisia campestris, but the 

 specimens were bad ; also from the same plant, beautiful specimens of 

 Conchylis Kindermanniana, the $ of which flies as readily as the £. 

 Amongst these were two beautiful males of the second brood of Con- 

 chylis Richterana. Specimens of Coleopliora vibicigerella were wasted. 

 Three plumes occurred here ; pilosellce — not uncommon ; tristis — less 

 frequently ; and of obscurus only one specimen ; they were easy to see 

 and to catch in the twilight. Amongst several Anerastia lotella which 

 started from the grass stems, one $ was still in good condition. I also 

 found one worn female of Melissoblaptes bipunctanus low down amongst 

 the Artemisia. Amongst the abundant Gelechia terrella on the slope 

 of the canal, I took two Gelechia lutatella, which I recognised immedi- 

 ately by their whitish anterior legs. I sought for them here, as I knew 

 the species occurred here, having previously observed the rolled leaf of 

 the Agropyrum repens which grows in plenty at the spot. I also took 

 here a good specimen of Botys frumentalis. 



After the sun was gone down, the insect world appeared as though 

 dead, and I had to beat about a good deal in order to induce anything 

 to fly. Gr ambus alpinellus, however, along with two specimens of 

 Homceosoma nimbella, without heeding the cold air, visited the blossoms 

 of Jasione montana. 



As I returned homewards along the dry grassy border of the road, 

 where there were much Achillea millefolium and only a little Artemisia, 

 there flew up in the dark two Conchylis dipoltella, which I had not 

 before found near Meseritz; they had quite the flight and the appearance 

 of Conchylis Kindermanniana, for which indeed I took the first specimen 

 when on the wing.
