MYRMECOPHILOUS NOTES. 61 



at Weybridge, Oxshott, and Darenth Wood before. On October 1st 

 I found J s hovering over a rufa nest at Weybridge. 



Melichia ludens, Wahl. — I captured a J of this species on May 2-lth 

 in the nest of L. fulitjiniiKitH at i)arenth Wood, where I discovered the 

 species new to Britain last year, when I took a 2 . 



I'hora rata, Wood. — On the morning of January 8th, 1910, 1 noticed 

 a, small fly in my cxsecta nest, which was running and flying swiftly 

 about. When it met an ant it shot quickly away. An e.vsecta $ , which 

 had just died, was being carried about by another ^ . It is probable 

 that it had bred out of the dead ant. It may be remembered that I bred 

 specimens of this fly, which came out as larvte, from a beetle, Clerus 

 forinicarins, which I had captured alive in Sherwood Forest. 



Plinia aecjualis, Wood. — This species was again common at Darenth 

 in the fidiijinosua nest, on April 2nd. 



Phora ciliata, Zett. {inaequalis, Wood). — This species was captured 

 in the same nest as the above species. I found it with the same ant 

 in numbers right in the nest in a hollow post, at Wellington College, 

 in 1906. 



Heteroptera. — Pilophoras perple.vns, D. and Sc. — A young larva of 

 this bug was found in a nest of F. sani/uinea, at W^oking, on May 9th, 

 1909, and several adults Avere beaten from pines in company with L. 

 ni(ier on .July 80th, 1910, in the same locality. 



Braconid.e. — Kujilioius bistii/iiiaticns, Morley. — Females were ob- 

 served on October 1st hovering over a rufa nest at Weybridge. 



Chasnwdon ajiterun, Nees. — I captured a specimen in a fiili'jiiiosus 

 nest at Darenth Wood, on October 27th. 



Proctotrupid.e. — Tricliopria foriiiicaria, Kief. — This species, which 

 is new to science, Avas found in a nest of F. fiisca, under a stone, at 

 Box Hill, on May 20th. 



Ambli/aspix scnteUaris, Kief., var. Injalniiis, Kief., and Jh'lijta ftircata, 

 Kief., var. formicaria, Kief. — These two insects, which are both new 

 varieties, were taken in the fiiligiumus nest at Darenth Wood, on 

 October 27th. I must again thank Prof. Dr. T. T. Kieft'er for kindly 

 naming my specimens for me. 



CoLLEMBOLA. — (_' tjphodeims {Bechia) albinos, Nicol. — This little 

 creature occurred in great numbers in my rufa nest, and as many as 

 six and seven would often be on one ant at a time. I have never seen 

 them on the ants before. It also occurred in my exsecta nest, and on 

 December 8th, Crawley and I found it in a L. umbratus nest at 

 Weybridge. 



^LYRiAPOBA.^I'oli/.veniia laf/tints, L. — I captured several specimens 

 of this curious little species in my F. rufa nest on November 

 11th. I have frequently seen it in great numbers with this ant at 

 Weybridge, where my nest came from. Bagnall tells me he has taken 

 it with F. rufa and F. fiisca in Norviay, and Randell-Jackson writes 

 to me that he has found it with F. rufa at Burnham Beeches, on May 

 30th, 1908, and has on several occasions found it with the same ant 

 in different localities, always in some numbers. It is figured in the 

 Cambridge Natural History," where it is stated it defends itself by 

 means of the long and stiff bristles with Avhich it is provided. The 

 yellow tuft of hairs at the end of the body have a rather Myrmeco-
