Aran, lunatus Clerck:, which Sundevall (loc. cit.) and Westring 

 (Forteckn. etc., p. 39) would refer to this species , is assuredly nothing 

 else than a lighter form of the following, as both Walckenaer and 

 C. Koch have supposed. (Vid. inf.). 



The original country of Th. tepidariorum is not as yet with 

 certainty known. In the north of Europe it appears everywhere to 

 have been imported from a warmer climate. Most of the writers 

 who mention it (for instance, C. Koch, Blackwall, Seidel, Bockh), 

 have only found it in hothouses, not in the open air. Sundevall 

 met with in on board a ship, in which he in 1827 — 28 made a voyage 

 to India; that ship had the previous year returned from Lisbon, 

 and he accordingly concludes that the species belongs to southern 

 Europe: he adds however, that it bore the tropical climate admirably 

 for more than a year, and left an innumerable progeny (loc. cit., p. 

 53). C. Koch and Blackwall look upon it as an originally exotic 

 species , and that is also my opinion : I possess in fact several speci- 

 mens of 77t. tepidariorum from S. Paolo in Brasil, and according 

 to Cambridge ') it is also met with in Ceylon. — Here in Upsala 

 it is only to be found in hothouses, but in Goteborg I have several 

 times captured it in the hollows and angles of the outer house- 

 walls in a street, Stora Hamn-gatan, where Westring also found 

 it. Nordmann also, who in Finnland saw it only in hothouses, has 

 once met with it in the open air in the south of Kussia, not far 

 from Ekarinoslaw 2 ).
