NEW AND RARE BRITISH SPIDERS 47 



Bolyphantes expunctus Cb. Three years ago I recorded 

 this species from the neighbourhood of Forres, where it 

 was taken by Mr. J. W. H. Harrison, but the exact 

 habitat was not known. To re-discover it and learn 

 something of its life-history was the main reason why he 

 and I visited that district in August, 1910. We succeeded 

 in locating it in the Altyre pinewoods (famous among 

 lepidopterists as a breeding place of Eitpithecia togata, 

 and with botanists as one of the few habitats of Goodyera 

 refens) where it swarmed on the lichen-covered conifers. 

 On the clean conifers comparatively few were found, and 

 on other trees only stray examples. As far as I could 

 discover it makes no snare of any kind and evidently 

 subsists chiefly on the pine aphis. It comes to maturity 

 about the middle of August, a good many examples being 

 still immature on the 17th. Very nearly 300 adult 

 specimens were taken in a very few minutes. Since then 

 I have learnt from Mr. W. Evans of Edinburgh that he 

 has taken it plentifully on juniper at Aviemore, where it 

 was associated with Dictyna arenicola Cb. 



Oreonetides adipatus C. L. K. Adult female, Killhope 

 Law, August, 191 1. 



Oreonetides firmus Cb. A single adult female occurred 

 in the birch wood on the southern border of Culbin sands. 

 First record for Scotland. 



H i laira frigida Thor. — H. tnontigena L. K. of British authors. 

 By the kindness of Dr. de Lessert of Geneva, I have a 

 pair of Swiss examples of H. montigena L. K., which is 

 quite different from our British spider. After some 

 correspondence with Dr. Kulczynski and Mr. Cambridge 

 I have come to the conclusion that our British spider 

 should be called H. frigida Thor. A single adult female 

 was taken at Lochan Dorb, Inverness-shire, in August. 



*Hilaira nubigena sp. n. Killhope Law. Description, 

 etc., below.
