SMINTHUPJDAE. 



Sminthurides Borner. 



Sminthurides Malmgi-eni (Tullberg). 



This species — the only member of its family known to inhabit 



Spitsbergen— was first recorded from the archipelago by Tullberg (1876). It 



was found by the Oxford Expedition at Klaas Billen Bay (one specimen on 



surface of freshwater pool in raised beach near Bruce City, 29th July, 1921) 



and on Bear Island (six specimens under stones near Elassia Lake, 17th June, 



1921). It has apparently not been previously noticed on Bear Island. The 



specimens are referable to the dark violet " type form " of the species, which 



is especially characteristic of Arctic regions, but some of the Bear Island 



examples were red when alive. In the temperate portions of its range — 



Great Britain, Germany, and Switzerland — it is represented by the prettily 



variegated ioxm. elegajitula (Eeuter).
