38 THE entomologist's record. 



in a nest of 1^ . fnna at Box Hill, on April 4th. I have'-'' recorded it with 

 ants last year. 



AcARi. — Trach\jnrnj)oda laiiiinoaa, C. and B., occurred in nests of 

 F. fiisca at Poriock, on April 28th. 



Trachijiiruiioda icasinannia iia, BevL — Several specimens (<? s) were 

 found in a nest of L. miibratiis at Wellington College, on May 6th. 

 This is its first record for Britain. Berlese^" records it as taken by 

 Wasmann in Luxemburg in nests of L. mixtiis, and remarks that he 

 is not acquainted with the male. 



Umpliti'lla )iiiiiiitissiiiia, Berl., occurred in plenty in my L. uinbyatus 

 nest from Weybridge. 



VroilisceUa jihiloctena, .Janet. — 1 recorded*^ this new species to 

 Britainas rropoilaphiloctena, Trouessart (itisonly a question of synonym 

 not an error, see Berlese loc. cit., p. '642), in my L. nmbratus nest from 

 Weybridge. The specimens were fastened to the strigils of the ants as 

 figured by"^ Janet. It also occurred at large in the 7>. tDnbratus nest 

 at Wellington College and in my Weybridge L. iiwbratiis nest. 



Uropotla oralis, Kram. — Specimens were found on ants in the 

 L. u))ibratiis nest at Weybridge on April 4th, and on the same ant at 

 Woking on May 10th. These mites are fastened to the femora of the 

 ants, Janet {loc. cit.) only records them on the second leg, but I have- 

 found them on all three. 



Laclaps )in/niiecopJiiliis, Berl., occurred at St. Issey, in Cornwall, in 

 nests of F. fusca var. fusco-mfibarbis, and with M. lacvinndis on the 

 Isle of Eigg, on September 17th. 



Laelaps ciincifcr, Mich. — In nests of F\ fiiRca on April 27th, at 

 Poriock, and with L. iinibratiis and L. fitli(/inosits at Wellington College, 

 on May 6th. 



Cilihann comata, Berl., occurred on the small larvae in a nest of 

 L. nif/er and on the large larvpe in nests of L. flavus at Box Hill, on 

 May 7th. I also found specimens on the abdomen of the ants, as 

 figured by^^ Janet, in L. lonbratns nests at Woking, May 10th, and 

 Weybridge, July 22nd. 



Antennaphonis uhhimuni, Hal. — I found this species (of which 

 only two specimens had been taken in Britain before by MichaeP* at 

 the Land's End) in numbers, on the ants in nests of L. itnibratns at 

 Woking, on May 5fch, and Weybridge, on July 22nd. In Antcunophonis 

 ijraniUs, with L. fiiliiiinnsun, the mites are nearly always only to be- 

 found on the chin of the ant, but with this species they are frequently 

 on the abdomen as well as the head, as figured by Janet.*^ In A. (jrandis 

 the mite is fed by scraping the mouth of the ant on which it is with 

 its front legs, when the ant lets out a drop of fluid, which the mite 

 sucks up. In this species the mite is often fed by other ants besides 

 the one on which it may be. On May 11th I introduced ^ s of L. 

 Kiiihratiis from Woking, which had specimens of the AntennopJiorua on 

 them, into my umbratiis nest from Weybridge. I expected that the
