Notes on the British Myrmecophilous fauna (excluding Coleoptera). 



By HORACE DONISTHOEPE, F.Z.S., F.E.S. 

 {Concluded froui p. 40). 



Myeiapoda. — Wasmann [Inc. cit., p. 192) states, that one often 

 finds, in the ant-hills of FoDiiica rnfa, etc., in ants' nests under stones, 

 and under bark with LasiuH briDDunis, species of Myriapoda, though he 

 doubts if they belong to the true " lodgers." 



Bhnijidus iiuttulatiis, Gervais {^Jidim pulchellus, Leach). — I often 

 find this species in the nests of Formica riifa. It was very abundant 

 in a nest of LasiusfuUi/ino.sus at Oxshott. Mr. F. G. Sinclair, who 

 kindly named the specimens for me, writes as follows : — " I think the 

 reason of their frequenting the ants' nests is very likely the quality of 

 the earth they get there for making their nests. They make regular 

 receptacles for their eggs, built up of little balls of earth that they 

 moisten with their saliva and roll up between their front legs, and it 

 is not every soil that is suitable for this process." 



Arachxoidea. — PsEUDoscoRPioNiNA. — Ohristiwi niiiscoruDi, Leach. — 

 I have taken this Chelifer several times in the nests of Formica rufa 

 at ^Yeybridge and Oxshott. 



Chthoiiiua rai/i, L. Koch. — I have taken this species in the nest of 

 Lasim ftdviinosus at Oxshott. 



ChtJioniii!^ haJmii, C.L.K. — I have taken this species in the nest 

 of Lamis fidi(jinoxus at Oxshott. Wasmann {Lac. cit., p. 193) remarks 

 that one often finds species of the genus Chelifer in ants' nests. 



Akaneina. — T/njrensthemti.s hiarata, Cambridge. ^ — I took a $ of this 

 small spider in April, 1900, in the nest of Fomrica rnfa in Guestling 

 Wood, near Hastings. It had not been found in Britain before. 1 

 have since found it in numbers (both sexes) in the nests of Forxiica 

 rufa at Weybridge, Oxshott, and the Blean Woods. Wasmann (loc. 

 cit., p. 193) gives its normal hosts as F. nifa and 7''. jirateiifii.s. It is 

 found in the heart of the nest. On April 26th, 1901, I brought up 

 from Oxshott six specimens of this spider from a nest of F. rnfa, and 

 introduced them into my " observation nest." They at once entered 

 the galleries, the ants paying no attention to them. I did not see any 

 of them again till June 23rd, A\hen a ? came uj) accompanied by a 

 number of young ones, so they must have bred in my nest. After 

 this specimens were observed on June 25th, 27th, 30th, July 18th, 

 21st and 27th. On September 19th quite a number were walking 

 about in my nest. The last specimen observed was on November 26th. 

 When they meet an ant they spring with great quickness to one side. 



Tetrilns arictinns, Thor. — The Rev. 0. P. Cambridge {Fnt. Record, 

 1900, p. 163) writes : " I have received from Mr. Donisthorpe an adult 

 and an immature cT of a most remarkable spider of the family
