Leptothorax nylanderi prefers to dwell in shady places in woods 

 and coppices, where it chiefly nests in wood, and under bark, in 

 which it excavates small galleries, and it will sometimes appro- 

 priate the old borings of other insects. Schenck 3 says it occurs in 

 moss on trees and rocks, and Mayr 5 also mentions that it some- 

 times nests in moss. It may be found in fallen boughs, and at the 

 foot of old tree trunks, but it never occurs under stones. 



Saunders took solitary workers by sweeping at Chobham and 

 Wimbledon 14 , and Morley records it as occurring on Linaria 

 vulgaris (Yellow Toad-Flax) in the summer near Ipswich 23 . 



Curtis records that Wing found it under oak-bark at Brixton in 

 April 4 , and there are specimens in the late Frederick Smith's 

 collection taken under bark at Camberwell in March, 1852. I am 

 inclined to think the latter are from the same source, as a specimen 

 in the British Museum labelled " Camberwell " was also taken by 

 Wing. 



Farren-White found a small colony consisting of nine queens and 

 sixteen workers in an old stump at Lee near Blackheath on 

 September 9th, 186 1 20 , Harwood found nests at Bures under 

 poplar-bark 22 , Morley took a specimen under the bark of a dead 

 willow at Ipswich on February 13th, 1894 21 , and he says it is 

 common in the winter beneath aspen and maple bark in that 

 district 23 . In October, 1914, I visited Morley's locality near 

 Claydon and found five or more colonies under bark of poplar. 

 These colonies of about fifty workers and one queen in each, were 

 situated under small bits of very close-fitting bark. 



Parfitt found a colony in August, 1864, in a hollow stick near 

 Exeter 13 , and I discovered a strong colony, situated in a fallen 

 bough in Richmond Park 25 in June, 1907, which contained one 

 deflated female and a number of workers and brood. 



Parfitt records another colony which occurred in a lane leading 

 from Marypole Head, Exeter, to Cowley Bridge, in an old oak 

 stump which had been bored into by some beetle, probably an 

 Anobium, and in those holes the ants had their runs, their nest 

 being in a larger hole 13 .
