22 THE entomologist's record. 



which were attending them. The very long probosis of this plant 

 louse is very remarkable. On October 7th I went down again to try 

 and get specimens for Mr. F. Laing of the British Museum, to whom 

 I am indebted for the identification of many species of Aphididae, and 

 secured a few more which were also attended by the ants. The only 

 other known British locality is Dulwich, where it was taken many 

 years ago by the late F. Walker. 



ACARINA. 



iJroplitella donistliorpii, Hull. — In the Vascnliim for February 

 [7 18 (1921)] , the Kev. J. E. Hull described this new rayrmecophilous 

 mite from specimens taken by myself. These were taken in a nest of 

 A. (C) fiavus at Box Hill on May 1st, 1910, and in plenty with 

 Myrmica Itrrinodia on May 20th in the same locality. These were 

 queried as U. ovatnla, Berl., by Mr. N. D. F. Pearce, and recorded 

 doubtfully as such [Ent. /iVr. 23 170 (1911)]. I found another tube 

 which contained a number of specimens taken in a nest of Mi/rmira 

 srahrinodis v. aahiileti, likewise from Box Hill, on May 20th, 1910. 

 These were also identified as U. dunisthovjiii by Mr. Hull. 



I took the true (/. ovatnla in a fiavus nest at Bradgate Park, 

 Leicestershire, on May 3rd, 1909. These little mites are to be found 

 in the bare galleries of the ants, in nests situated under stones. 



According to Berlese, in his monograph on the Myrmecophilous 

 Acarina, the males of the following three species are unknown to 

 science. As I find I possess males of all of them, it seems as well to 

 record the fact here : — 



(1) SplurrolaiapR holotlnjioideii, Leon. — Mr. Crawley having told me 

 he possessed a <? of this species, I proceeded to examine all my own 

 material. I found two $■ J , one I took in company with many $ J 

 in a nest of A. {C.) unibratua at Wellington College on June 19th, 

 1909, and the other with A. (C.) mij-tns at Box Hill on May 23rd, 

 1913. The femur of the second leg in the <? is armed with a book. 



This curious mite was first recorded as British by me, from a 

 specimen I took in a nest of n»ib>atiis at Bewdley on May 21st, 

 1908 [Knt. Her. 21 20 (1909)] . I remarked— " The mite is the same 

 colour as the ant, and when it moved it looked like the abdomen of an 

 ant walking by itself." I have since taken it with ttnibratus at Woking, 

 Wellington College, Weybridge, and Box Hill ; and with niixtits at 

 Box Hill and Lundy Island. I have kept the species in captivity on 

 numerous occasions. In 1911 I wrote : — " I introduced a number 

 from Box Hill into my uHibratus observation nest, where they lived for 

 a few months. They sit about with the ants and run in and out 

 among them. The ? ^ sometimes appeared to threaten them with 

 their jaws, but never bite them." [FJnt. Rec 23 63 (1911)] . 



(2) Anti'iutojt/ionis uhlnianni, Haller. — This species occurred in 

 great numbers in a nest of ninbratiis at Woking on May 6th, 1911, 

 and again on May 10th. I find that nearly 90% of the material 

 I took then are J <? . I subsequently took it with the same ant at 

 Weybridge, and with )»ut//.s at Box Hill. In my notes for 1911 [Knt. 

 liec. 24 38-9 (1912)] I gave an account of the habits of this mite, and 

 how it is fed, etc. 



(3) Antennop/iorus fureli, Wasmann. — On July 12th, 1907, when at
