40 THE entomologist's record. 



Cn/phoecia recisa, Camb. — A $ was taken with L. uiiibratttn at 

 Weybridge, on April 20th, and two 2 s, with the same ant at 

 "Wellington College, on May 6th. The spiders were underground with 

 the ants. Another J and two young ones were found in the galleries 

 of a F. rufa nest under a heavy stone at Porlock, on April 28th. 

 Kandell Jackson tells me he believes this spider to be the J of Tetiilus 

 arietinus, Thor., of which the ? is unknown, as is the case with the 

 ^ of C. recisa. 



Eransia )nereiis, Camb. — Was found in nests of 7*'. fusca at Rannoch 

 on June 10th and 14th. 



Hahiiia helvcola, E.S.— Two in a nest of L. falitjinosus afc Oxshott, 

 June 1st. 



Micaria ptilicaria, Sund.- — Again with F. sanyuinea at Woking, May 

 €th. 



Harpactes Jiomberifi, Sep. — In nests of F. fusca var. fusco-rnfibarbis 

 and L. nvjer at St. Issey, on April 25th. 



Crustacea. — Plati/arthnis hoffniansei/i/i, Brandt. — In 1909 *'Standen 

 writes — " The nest of Fonnica ftava appears to be the principal 

 habitat of I'latyart/iras, indeed, I can only find one solitary record of 

 its occurring along with any other species, viz., in the nest of Mynnica 

 rubra, where it was observed by Mr. E. E. Lowe, at Newton Ferrers 

 {Webb and Sillem)." This, however, is by no means the case; in 1902^° 

 I record that I have taken it in Britain with F. rufa, F./ttsca, and F. 

 sanyidnea, L. iiavns, L.fidiyinosns, L.niyer, L. )iiiibrati(s, Ciud L. olientts, 

 M. scabrinodis, M. lai'vinodis and M. sulci nod is. I also mention the 

 seventeen species of ants with which Wasmann" recorded ifc. Hogan,^- 

 who first discovered it in Britain, found it with F, rufa, L. fiavus, and 

 L. niyer, at Lulworth Cove. This year I have found it with F. fusca 

 at Box Hill, April 13th and 22nd ; L. fiarus at St. Issey, April 25th ; 

 L. niyer at St. Issey, April 26th, and Porlock, April 27th ; Tetrauioriuiu 

 caesjntuni at St. Issey, April 25th; M. ruyinodis at Porlock, April 28th; 

 L. uiiibratus, L. fuliyiiiosus and F. rufa at Wellington College, May 

 6th ; and M. scabrinodis at Box Hill,' May 7th. In 1910 Crawley^' 

 records it with L. Jiarus and L. niyer from Oxfordshire and Surrey, 

 and gives some interesting experiments which show the ants do not 

 always treat the wood-louse in the same way. On May 8rd I introduced 

 six Platyartltrus from a Myrmica nest at Boxhill, into my L. rJavus nest. 

 The L. /larus '^ s soon killed them all. On April 14th I introduced 

 specimens from Box Hill into my F. fusca nest from Hartlepool. 

 These were not attacked, and bred in this nest, a number of little ones 

 being seen. They lived till September, when the nest was destroyed 

 by having been kept too dry.
