ON SOME NEW AND RARE BRITISH COLLEMBOLA 507 



Genus SMINTHURINUS Borner 



Sminthurinus csecus (TnWh.) forma principalis. 



The type form of this species, hitherto unrecorded from our 

 islands, occurs not uncommonly under flower pots in a house 

 at Hylton, near Sunderland, and examples sent me by Dr. 

 Norman H. Joy collected by him from moles' nests in 

 Ayrshire would also appear to be referable to the type 

 form. 



I have taken the var. attemiatus Carpenter and Evans, in 

 hot-houses in Glasgow, London, Newcastle, Alnwick, Wylam- 

 on-Tyne, and Winlaton ; these English records being the first. 



Sminthurinus niger(Lubb.) 



In greenhouses, Newcastle and Wylam, and a solitary 

 specimen in an old garden at Ayr. 



Sminthurinus aureus (Lubb.) 



Apparently common tliroughout the year amongst dead 

 beech leaves, Gibside. 



Sminthurinus igniceps (Renter). 



A few examples from the Botanical Gardens, Glasgow, and 

 from a hot-house in Leazes Park, Newcastle-upon-Tyne, 

 these latter making another addition to the English fauna. 



Sminthurinus bifiavopunctatus (Collinge and Shoe- 

 botham, 1909). 



Sniintlwrjis biflavopunctaius Collinge and Shoebotham, 

 Journal of Economic Biology, iv., no. i, p. 9, pi. in, 

 figs. 1-7, 1909. 



A hot-house species, which from its relationship to S. 

 igniceps would seem to be referable, under our present classi- 

 fication, to the genus SniintJuirinus. Nearly two years ago I 

 found S. hiflavopnnctatus commonly in hot-houses of the 

 Botanical Gardens, Glasgow, and have since seen it in
