98 THE ENTOMOLOGIST. 



In the ' Entomologist's Annual ' for 1857, Mr. Janson draws 

 special attention to the Myrmecophilous Coleoptera, or ants'- 

 nest beetles of Britain, with instructions for obtaining them, and 

 giving a list of thirty-six species. In the following 'Annual' he 

 gives further notes, and states that ants' nests have contributed, 

 within two years, upwards of twenty species of Coleoptera 

 previously unknown as inhabitants of Britain, and have, more- 

 over, yielded, in comparative plenty, no trifling number which 

 were previously unique, or of the greatest rarity in collections. 

 He also finds fault with certain individuals for ruthlessly 

 destroying the nests, and commends the ants to his readers' 

 sympathy. 



Since 1858 the list of British Myrmecophilous Coleoptera 

 has been largely added to, as may be seen by reading through 

 the Eev. Canon Fowler's 'Coleoptera of the British Isles.' There 

 are, moreover, various species of Aphides and Coccidse attached 

 to ants' nests, with a small sprinkling of others belonging to the 

 Psoci, PhoridfB, and Tineidae, families of the Neuroptera, JJiptera, 

 and Lepidoptera; whilst the Thysanura, Acari, and Onisci have 

 also representatives. 



Formica sanguinea, Latr. — This is, pew excellence, the slave- 

 making ant of our British species. It is local, being found 

 chiefly in the sandy districts of Surrey. In the ' Entomologist's 

 Annual ' for 1868 Mr. F. Smith gives a list of nine other species 

 of ants found in a nest of F. sanguinea on Shirley Common by 

 Mr. Piothney. F. fusca, common ; F. nigra and Jiara, several 

 specimens ; Topi noma erratica, Myrmica ruciinodis, and M. 

 scabrinodis, common ; M. lobicornis, workers very abundant, but 

 only one female ; Leptothorax aceiTorum, all the sexes abundant 

 in August ; L. nylanderi, several specimens. I can find only two 

 species of Coleoptera recorded as being found in the nest of this 

 ant, viz., Dinarda maerkeU, Fries, taken by Messrs. Douglas and 

 Scott near Croydon ; and Hetcerius sesquicornis, Preys. 



Formica rufa, L. — In the nests of this species another ant, 

 Stenamma ivestwoodii, seems only to occur. The species of Cole- 

 optera are numerous: — Aleochara rujicornis, Grav. ; Oxiipoda 

 recondita, Ter. ; 0. for mice ticola, Maerk. ; 0. luemorrhoa, Minn; 

 Thiasophila angulata, Er. ; Dinarda maerkeli, Fries ; Myrmedonia 

 humeralis, Grav.; Notothecta flavipes, Grav.; N. anceps, Er. ; 

 Quedius brevis, Er. ; Leptacinus formicetorum, Maerk. ; Dendro- 

 pliilus pygmceus, Lin.; Myrmetes piceus, Payk.; Monotoma coni- 

 collis, Aube ; M. formicetorum, Thorns.; Ptenidium formicetorum, 

 Ter. ; Ptilium 7nyrmecop]iilinn, All. ; Euplectus signatus, Pieich. ; 

 Batrisus venustus, Eeich. ; Scydnuenus godarti, Latr. ; Neurophes 

 longicollis, Mots. ; Cetonia cenea, Gyll. (larvae) ; Clythra qiiadri- 

 punctata (larvae) ; C. tridentata, Lin. (larvae) ; Coccin<dla labilis, 

 Muls. The following Homoptera occur : — Paracletus cimiciformis, 

 Heyd.; Fordaformicaria, Heyd.; Trama troglodytes, Key d. Also
