This species, which is well known on the Continent, has occurred in 
France, Switzerland, Germany, Hungary, Sweden, Lapland and Russia. This 
is its first record in Britain. The structure of the palpi and epigyne easily dis- 
tinguish it from all its congeners. The abdominal pattern, whilst resembling 
that of the two common species, is sufficiently distinct to render the species 
recognisable to the naked eye. See figure in Bésenberg, loc. cit. The present 
species is adult in June, and presumably July, whilst the others are in this 
country rather sharply autumnal animals. Z. Stremii occurred commonly on 
the trunks of pines in certain spots in the Black Wood of Rannoch. The 
webs, which resembled those of our common species in having a free radius, 
were spun on the trunks of the trees from a foot or two above the ground to 
a height of at least seven or eight feet. Only three adult males were found 
and nearly a score of adult females. A great number of both sexes were 
immature individuals of different sizes. The species was very local in the 
wood, the best place being a clump of young pines growing in a swamp close 
to the road, almost opposite the sixth milestone from Kinloch Rannoch.
