During the latter part of June and the first fortnight in July 

 the butterfly season is at its height, and we made many excur- 

 sions to the localities above mentioned. The 13th was a lovely 

 sunny day, which we again spent at Finkenkrug. One of the 

 first butterflies captured was a fine specimen of Papilio machaon ; 

 a specimen of Mamestra glaiica was found at rest on a tree-trunk, 

 and almost immediately afterwards we were in the thick of the 

 Melitaeas — at present only M. aurinia and M. cinxia ; while 

 Lyccsna amanda, L. icarus, Chrysophanus hippothoe, and C. alci- 

 phron are abundant. The tree-trunks are now frequently tenanted 

 by Psychid cases — Sterrhopteryx hirsutella, Acaiithopsyche opa- 

 cella, Canephora unicolor, Bacotia sepium, Epichnopteryx pidla, 

 and E. nitidella. A peculiarity about C. unicolor is that only 

 the males select tree-trunks to spin up on ; the female cases are 

 always found spun up amongst herbage. Geometras seem to 

 have tailed off, the only Larentias observed being tristata, ocellata, 

 and sociata. In the meadows, however, Acidalia immorata was 

 fairly common, with occasional A. ornata and A. immutata, S. 

 clathrata and M. murinata. On tree-trunks, A crony eta j) si, A. 

 leporina, A. ahscondita, Momaorion, Sjjhinx jmiastri, and Boarmia 

 consortaria were frequent : one specimen of Drymonia chaonia 

 and two of Lophopteryx camelina beaten out of oak, and D. 

 lacertinaria netted. Larva-beating was almost too trying owing 

 to the heat, and very little worth mentioning obtained. Oak 

 produced Catocala sp)onsa (full-fed), and Zephynis quercus, while 

 Herr Wadzeck was fortunate enough to beat a larva of Arctornis 

 {Laria) l-nigriun from lime. In the afternoon a case of Psyche 

 viciella was found among herbage, several worn specimens of 

 Hemaris bomhyliformis netted, while a grove of old aspens pro- 

 duced the larvse of Trochilium melanoccphalum in plenty. The 

 method of obtaining these latter is fairly simple ; the lower 

 twigs and branches die off in the same manner as do those of firs, 

 and all one has to do is to break off these twigs, and examine 

 the fracture for the fresh galleries of T. melanoccphalum. In 

 this manner we obtained about a dozen larvae in a very short 

 time. The smaller aspens were beat for larvae of Apatura ilia 

 and Limenitis popidi, and a few of each were obtained. 



Sugaring one night at Wusterhausen was very successful, 

 and the following were obtained in numbers : — Acronycta psi, A. 

 menyanthidis, A. auricoma, A. ahscondita, A. rumicis, Agrotis 

 ohscura, A. simulans, A. cinerea, A. exclamationis , A. segctum, A. 

 primulcR, Mamestra leucophaa, M. nehulosa, M. hrassicce, M. alhi-
