84 THE entomologist's recoed. 



found at the foot of trees inhabited by L.fidiiiinoaua, and he goes ovs 

 to demonstrate that the J L. fidiginosns has founded her colony in the 

 L. iwibratas nest. Crawley has recently recorded that he found ^ s of 

 L. ujiibratHs in company with L. fulif/inosiis. 



In the Ent. Record, 1897, p. 246, I recorded that I found a large 

 nest of L. fidiginosuii in the hollow of a tree at Lymington, and that 

 Lasius tl((vus was living with it, both species coming in and going out 

 together. I am now convinced that the species was reallj^ L. uuibratus, 

 I was not so well acquainted with our ants at that time, and I remember 

 distinctly thinking how large the L. ^lariis ^ s were. Dr. Joy has 

 shown me a large nest of L. nmbratua at Wellington College, in the 

 heart of a district thickly populated with L. faluiinosus nests. 



The following observations should have appeared in my Myrmeco- 

 philous notes for 1909 : — 



PsEUDOscoRPiONiN^. — Chemes scorpioides, Herm. — In May last this 

 species was found in the greatest profusion in F. mfa nests at Buddon 

 Wood, Leicestershire. Mr. Wallace Kew, who kindly identified them 

 for me, told me there were $ s, $ s, and $ s carrying eggs externally,, 

 present. They occurred in the nests, literally in thousands, especially 

 at the very bottom of the nest. Every handful of the debris of the 

 nests placed on paper was seen to be swarming with the Chelifers. 

 The ants paid no attention to them. It has been recorded with the 

 same ant in Denmark by Hansen. I have taken it sparingly with F. rufa 

 at Weybridge {Ent. Bee, 1907, p. 255), and have introduced specimens 

 into my observation-nests. The ants treated them with indifference.. 

 When a F. rufa ^ was forced to take hold of a Chelifer, it dropped it at 

 once. I think it is quite clear that this species, at least, cannot be said 

 to have " nothing to do with ants." Ideoronciiscambridf/ii, L. Koch. — 

 Several specimens Avere found in nests of L. jinvus at Virtuous Lady 

 Mine, in Devonshire, in April. Chthonius rayi, L. Koch, occurred in 

 a nest of F. mfa in Parkhurst Forest, Isle of Wight, in April. I have 

 taken this common species before with L. fulujinoaiis at Oxshott. 



PEOCTOTRYPiDiE. — Farai/ri/on mijrwecuphilus, n. s. — My friend, Mr. 

 F. Bouskell, and I found this little apterous species in a nest of 

 Lasius flavus in Bradgate Park, Leicestershire, on May 8rd last^ 

 Teleas inyrniecobius, n. s. ^ and Hoplocirijon Dnjniiecobius, n. s. 2 . — 

 I took these two specimens in a nest of Lasius fulii/inosus at Darenth 

 Wood on September 24th. Dr. Kiefi'er, who proposes these names for 

 the three above new insects, tells me that he gives the same specific 

 name to the last two because he believes that the genera Hoploijnjon 

 and Teleas are not distinct, and that these are possibly, therefore, 3 

 and $ of the same species. 



AcARiNA. — Vroplitdla minutissima, Berl., occurred in nests of Lasius: 

 niger at Box Hill in May. iJrotrachytes forwicarius, Lubb., with 

 L. flavus at Sandown, Isle of Wight, in April. Trachyuropoda cocciiiea 

 var, sinuata, Berl., with L. niyer at Cothill, near Oxford, in June. 

 Mr. N. D. F. Pearce tells me he considers this to be the same species as 

 T. excavata, Wasm. Laelaps laevis, Mich. ? — I took this specimen with 

 F. exsecta at Aviemore in May. Mr. Pearce writes that it is very large, 

 1200fi, and the hairs seem too pronounced for L. laevis. It is probably 

 new. Laelaps ooi)hilus,\N?iSi'n.- — I took a $ Forwica ru/ibarbis va,Y. fusco- 

 rufibarbis at Sandown, Isle of Wight, on April 24th last, with a number 

 of this little mite on her body. As this little species lives amongst the
