MYRMECOPHILOUS NOTES FOR 1921. 



J'/iyllniiii/za pupfe ; one on April 10th, and the other on September 

 20th. 



Braconid.e. 



BlaciiH iiia)iiillanas,R\ithe. — Mr. Hallett sent me a S of this l^racon, 

 which he had taken at Porthcawl, Glamorgan, on May 16th, 1921, in 

 company with ^ ^ of A. {]>.) ni/jer. The shape, colour, and general 

 appearance of the body and legs are very like the ant. The ^ of this 

 insect was unknown to science. 



PrOCTOTRYPID/'E. 



Helotioi an<»iialipeA, Pz. — Mr. Hallett took a t? of this Proctotrypid 

 in company with LA'ptothorax acervoritm at Candleston, near Porthcawl, 

 ill July, 1916. The insect in question is superficially so like a J of 

 the ant, that it was not until he was setting it together with ^ ^ oi 

 the Leptotliorax, he discovered it was not an ant. This and the 

 previous species were kindly identified by Mr. Morley. 



Ceraphnn sp. ? — I captured a specimen of a species of Ceraj>hon in 

 a nest of F. mfa at Westerhain on September 5th, 1921, which I 

 believe to be new to Britain ; at any rate I have not taken it before. 



Heteroptera. 



Piezostcthiis formicetorum, Boh. — This curious little myrmecophilous 

 bug was discovered by Harwood in a nest of Foniiica mfa in the 

 Limpsfield Woods, Kent, in some numbers, both nymphs and adults 

 being present. He showed me this nest on September 17th, when I 

 secured a few nymphs. This capture is of considerable interest, as 

 the bug has never been found in England before. It was first recorded 

 for Britain in 1872 from Aberdeenshire where it was taken in rufa 

 nests at Glen Lui (Hislop) and Bnemar (B. White). After this it 

 was not found again until 1907 when I turned it up in infa 

 nests at Rannoch, Perthshire. In May, 1909, 1 took it at Nethy 

 Bridge; and again at Hannoch in June, 1911, when it occurred in 

 some numbers in one mfa nest, both nymphs and adults being 

 present. In July, 1915, J. J. F. X. King found it with its usual host 

 at Bridge of Gairn, Aberdeen. 



Aphidid^e. 



Tetiant'iira nhiti, Geofi'. — This species occurred in some numbers in 

 a nest of A. {('.) flovus in my garden at Putney on March 25th. My 

 previous captures of this Aphid are as follows : in nests of — Mi/niiica 

 riuiinodis Loch Arher 31-iv-08 ; A. {(J.) «//eH('s Whitsand Bay 16-iv-09; 

 A. {€'.) /Ud'us, Myrmica seabrijiodis and Formica fiisca Bradgate Park 

 ;-3-v-09 ; A. [( '.) flariiH Darenth Wood 6-vi-09 ; Tetramnriuin caespitnui 

 St. Issey 25-iv-ll ; A. (('.) flanis Isle of P^igg 18-ix-ll ; and A. (C.) 

 //rtc/^sLundy Island 9-vi-13. Mr. Laing tells me he has kept a special 

 lookout for it, but has only found it on elm at Newlands Corner in 

 Surrey. I imagine however that he has not looked for it in Ants' nests. 

 It is very curious that a species which is associated with the elm should 

 occur in ants' nests on Lundy Island, and the Isle of Eigg, where elm 

 trees are not to be found ! There is much yet to be learnt about the 

 life history of most of the myrmecophilous Aphididae. 



('To be concluded.)
