shrubs in small plantation. Many specimens, all taken

This is a North European species, inhabiting Novaya 

 Zemlya, N'orway, Sweden, Finland, Switzerland, France, 

 Scotland, and Ireland. It was first recorded as a British 

 insect as /. sensihilis, Tullberg, in 1899 by Carpenter and 

 Evans.^ Its usual habitat in the Edinburgh district is also 

 rotten wood. The Faroe specimens show the four-toothed 

 mucro {loc. cit., pi. vii. fig. 27) characterising the form 

 /. denticulata, Schaffer, which Agren ^ identifies with Linne's 

 Podtora arborea. This name may therefore replace both 

 /. sensibilis, Tullberg, and /. cleiiticulata, Schaffer, which, 

 despite Agren's diagnoses (loc. cit., pp. 139-142), I still 

 believe to be specifically identical. 



[This species has probably been introduced into the Faroes 

 by the agency of man, as there is hardly any plant indigenous 

 to the islands which can even be called a shrub. I have only 

 seen it under the bark of the dead branch of an imported 

 shrub.] 



Tomocerus tridentiferus (Tullberg) — Thorshavn, under 

 stones in hayfields and on the moors. Numerous specimens. 



This is one of the commonest liritish species of the order, 

 occurring throughout Great Britain and Ireland. It is known 

 to inhabit Scandinavia, Finland, Germauy, Bohemia, the 

 Azores, and both North and South America, but seems to be 

 absent from the Arctic Eegions. 



[Extremely abundant under stones in the Faroes, ibrming 

 a very large part of the food of the small spiders found in 

 this habitat.]
