ON SOME NEW AND RARE BRITISH COLLEMBOLA 509 



Bourletiella bilineata (Bourl). 



On heather and heath, Greater Cambrae, CoHntraive in the 

 Kyles of Bute; Nethy Bridge, Inverness-shire; Ahiwick, 

 Haydon Bridge, and Corbridge, Northumberland ; and 

 Gibside, county Durham. I have this September found it in 

 numbers on the banks of Loch Lomond at Rowardennan. 



Bourletiella novemlineata (TuUb.), van tnsjg/iis (Rent.) 



By beating sedges, etc., and on the surface of brackish 

 water, Greater Cumbrae; Whitley Bay, Northumberland; and 

 Greatham, county Durham. 



I find pleasure in being able to record this species from 

 England. 



Genus SPYROTHECA Burner 



Spyrotheca Lubbocki (Tullberg), 1872, 



Stninthurus Lubbocki Tullberg, Sveriges Podurider, p. 38, 

 1872 ; Sfnint/uims pofipei 'R.euiQv, Abhandl. Naturw. Ver., 

 Bd. 9, Heft 2, 18, Bremen, 1885. 



This fine species is figured by Schott in his "Zur Systematik 

 und Verbreitung palaearctischer Collembola " (pi. in, figs. 

 1-4)*, and is recorded from Sweden, Finland, and Germany. 

 In July, 1907, I took a single example by beating heather on 

 the hills above Colintrave in the Kyles of Bute, Scotland, 

 which, so far as I am aware, is the only British example 

 known.
