FoHMiCA Ni&RA has similar babits to the preceding. 

 The following species are found: — Othius myrmecophilus, Kies. ; Astilbus 

 canaliculatus, F. ; and Claviger foveolatus, Miill. 



Formica sanguinea makes a nest somewhat in the same manner 

 as Formica rufa. 



With it are found Dinarda dentata and Hetarius ferrugmeus. 



With Mtrmica scabeinodis, ruginodis, and l^vinodis found 

 in old stumps and jander stones, Atemeles emarginatus occurs, and 

 with the last-named ant the other s,\iQc\e^, paradoxus, has been taken. 

 Lamprinus saginatus, Gr., is also said to occur with these ants. 



The very rare 3Iyrmedonia pUcata occurs with the rare ant, Tapinoma erkatica, 

 ■which I believe is only to be found at Bournemouth.* 



The very rare Bythinus glabratus is recorded in the Rev. Canon Fowler's 

 " Coleoptera of the- British Islands" as having been taken with a small yellow 

 Mgrmica in company with Trichonyx Mcerkeli. Trichonyx sulcicollis is also found 

 with ants. 



It will be noticed that many species of Coleoptera, other than those of true 

 Myrmecophilous habits, are found in company with ants, such as Homalota analis, 

 Gr., Xantholinus linearis, 01., and Exomias brunnipes, Ol., which are always 

 turning up. 



I cannot understand how it is that the ants tolerate their presence, 

 as I have frequently tried the experiment of introducing other species 

 into a nest, and they have invariably been attacked and dragged down 

 into the interior, even such large species as Ocypus olens, Creopliilus 

 maxillosus, or Pterostichus striola. 



In conclusion, I hope this paper may prove of use to some of my 

 fellow workers. 



The following is a list of the localities where I have worked for 

 ants'-nest beetles : — Sevenoaks, Weybridge, Tilgate Forest, New 

 Forest, Parkhurst Forest, I. of W., Blackgang, I. of W. ; Hastings 

 district : Bexhill, St. Helen's Wood, Guestling Wood. 



In connection with the foregoing notes, I have consulted the following writers 

 on the subject : —

Mag., XX, p. 40 (1883).

Britain. Ent. Ann., 1857, pp. 85—96. 



* Tapinoma erratiea occurs on the Surrey Commons— Woking, Chobham, &c., and also at 

 Crohimhurst, and Addington, near Croydon. — E. S.
