268 THE entomologist's recokd. 



else was found, though the nest might well have contained an 

 A}U'njateii-Tetra)iH))iiiw colony. Two small spiders taken with this ant 

 on June 11th and 12th are considered by Dr. A. Randell Jackson to be 

 Acortaiic/wniiis sctirrilis, Cbr. This little species, which is new to 

 Britain, is recorded by Wasmann with the same ant from the Rhine- 

 land and Bohemia. The Apliidac, Pcntap/iis waniinalin and VoyJa 

 formicaria were found, and in several nests a large number of 

 Paracli'tuii ciiiiiciforniis. The Ararus, Laelops cqiiitans was observed 

 riding on the ants. riati/arthriis ]ioff'iiianse(i;ii, Beckia albina, and a 

 Proctotrupid not yet named completes the list of myrmecophiles found 

 Avith TetroDioriitiii. In three different nests a number of seeds were 

 found, which Prof. Weise tells me are a Ceiastiuiii sp. ? 



Lasius niger, L. — Common. ] husilla canaliculata occurred in one 

 nest. 



LatiiitH alinms, Forst. — Not uncommon. The A/>hi)lac, Geoica 

 caniosa and Traiiia troi/lvdijtea, and the Coccid Jtiperxia subtcrrauea, 

 occurred in these nests. Fei/eiiiii/idlfia bracln/ptero, Kiefier, an ab- 

 berant <Sciara, with short wings, was found in the galleries of one nest 

 in June. This is its first record for Britain, and only two specimens 

 taken by Mons. Peyerimhoft' in Algeria have hitherto been recorded. 

 Trachtjitrojioda e.rcaiata, Wasm. ? A number of a small Acarii», 

 which appear to me to be this species, occurred in one nest. 



Lanius fiarits, F. — Common. Eggs, larvte, and J , $ , and ^' 

 pup;ie were present in most of the nests. In one very large colony 

 three deiilated $ J were found ; this is very unusual ; indeed, in our 

 paper on the founding of colonies by queen ants, read at the Inter- 

 national Entomological Congress for 1912, Crawley and I state that, 

 " Certainly, we know of no case where more than two females have 

 been found in one nest." This does not apply to virgin females, or 

 deiilated J 2 gathered together after the marriage flight, but in a 

 well-established colony such as the above. A Proctotrupid not yet 

 determined, Beckia albina, and the Aphidae, Tijcheoidcs hirstitiiin, N. S., 

 Tetraneura uhni and Alacrosip/uoii, N. S. (Theobald, MS.), were found 

 at large in neste of this ant, and the Acarus Cillibano coinata, fastened 

 on the larvfe. 



Lasiiis uii.rtiif;, Nyl. — Two colonies of this addition to the island 

 were observed which contained specimens of the Acari, Sphaerolaelaps 

 h(dothipoides and TracJnjiirupoda boatocki. Beckia albina also occurred 

 with this ant. 



Formica fimca, L. — Plentiful. Lai'ge colonies occurred under 

 stones which contained many deillated $ 2 . A number of micro- 

 gynes were present, some of them being deiilated, whilst four or five 

 possessed some wings, and wing-stumps, evidently from last year. 

 Eggs were found in all the nests, and larvje, and ? and sex cocoons in 

 some. Drnsilla canalicidata, a Chalcid, a spider which Dr. Jackson is 

 unable to name at present, and a number of a Laela])s sp. ? (near to L. 

 nu/nnophiliiK, Mich.) were found in these nests. The most interesting 

 discovery, however, was a large number of the larva?, all sizes, of 

 Atemeles enian/inatns, which were always situated on the ants' brood. 

 As soon as the stone over a nest w^as lifted up, the first thing the ants 

 did was to seize these interesting beetle larvae and endeavour to carry 

 them down the galleries into safety, and considerable celerity was 

 required to secure any. The perfect insect is recorded by Joy and
