RECORDS OF SOME SCANDINAVIAN WOODLICE. 



By Richard S. Bagnall, F.L.S., F.E.S. 



In June, 1909, I had to visit Norway on business, and took 

 the opportunity of extending my journey to Sweden and Den- 

 mark. Whilst most of my time was devoted to business matters, 

 I spent several happy hours collecting in the neighbourhood of 

 Bergen, Arendal, and Christiania, in Norway ; Gothenburg, 

 Sweden ; and Copenhagen, Denmark, taking a Springtail and 

 two or three Thrips new to science. I casually met with a few 

 Woodlice, and as Trichoniscus roseus, Koch, and Armadillidium 

 nasatum, B.-L., have not before been recorded from Norway or 

 the latter from Denmark, whilst Haplophthalmus mengii, Zadd., 

 Trichoniscus pygmceus, G. 0. Sars, T. roseus, Koch, Philoscia 

 muscorum, Scop., and Porcellio dilatatus, Brandt,* are apparently 

 new to the Swedish fauna, it is necessary to put the following 

 on record. Had I been aware at the time that the Woodlice of 

 Sweden were not well-known, I should have made a special 

 collection in that group. 



Haplophthalmus mengii, Zaddach. — Sweden : One specimen in 

 the public gardens at Gothenburg, June 28th, 1909. An addition 

 to the Swedish fauna. 



H. danicus, B.-Lund. — Norway : One specimen in the Tiaen- 

 havn Botanic Gardens, June 25th, 1909. 



Trichoniscus pusillus, Brandt. — Norway : Common ; Bergen, 

 Stend, Os, Egersund, Fevig, Arendal, Sandviken, and Christiania. 

 Sweden : Gothenburg. Denmark : Near Copenhagen. 



T. roseus, Koch. — Norway : In the hothouse behind the 

 Museum, Bergen, with Armadillidhim nasatum and Porcellio dila- 

 tatus, June 19th, 1909. Sweden : Gothenburg, June 28th, 1909. 

 Apparently new to both these countries. 



* A. M. Norman, Ann. and Mag. Nat. Hist. ser. 7, iii. p. 78, January, 

 1899. I base my remarks upon a table printed in above paper written more 

 than ten years ago. It is quite possible that the Swedish species have 

 received some attention since then.
