22 the entomologist's record. 



which sheltered a colony of A. (D.) alien us. On digging into this 

 nest, six deaiated mixtus 2 2 were found to have already established 

 themselves in it. 



The colony founding of all the British species of Acanthomyops is 

 now well known, and thoroughly established (see British Ants, pp. 

 185, 196-99, 208-10, 215-16, 221-22, 230-33, 239-40). It would 

 therefore seem unnecessary to keep on recording instances in support 

 of facts already well-known ; but a recent publication by Mons. 

 R. Stumper — " Zur Kolonie-griindung von Lasius fuliginosns " [Arch. 

 Naturg. 85 189 (1920)] , however, proves that it is still advisable to do 

 so. He found in the summer of 1917 two isolated fuliginosns 5 J in 

 cells, but with no brood, and a third in a cell under a stone which 

 covered a nest of A. ifi.) mixtus, but not communicating with it. He 

 therefore considers that further investigation is necessary. He 

 mentions the discovery of de Lannoy, and what Emery, Forel, and 

 Wasmann had to say about it, but totally ignores the extensive and 

 conclusive experiments carried out by Crawley and myself, besides the 

 various other records published since our earlier papers, and my book ! 

 I propose to republish the whole of the facts on the colony -founding 

 of this ant in a future paper; and possibly in some continental 

 publication. 



Formica rufa, L. — This ant was very forward in the south in 1920 ; 

 on February 18th the colonies at Weybridge were in full activity, 

 building up their nests, going from one to another, carrying their 

 fellows, and massing in numbers on the nests in the sun ; deaiated 2 2 

 occur in fair numbers with the £ $ outside the nests. 



On March 21st at Oxshott 1 found a winged rufa 2 out at some 

 distance from her nest ; this is the earliest date on record for either of 

 the winged sexes of this species : April 17th being the earliest former 

 record [see Brit. Ants p. 255] . 



Prenolepis (Nylanderia) longicornis, Latr. — On October 12th this 

 cosmopolitan species was found to be abundant in one of the hot- 

 houses at the Botanic Gardens, Regent's Park. The $ £ were 

 running about on all the plants and pots, both in and around a large 

 pond in the hot-house. This is the first record for the species in these 

 gardens. 



Coleoptera. 



Atemeles emarginatns var. niyricollis, Kr. — A specimen of this variety 

 was found in a nest of Formica fusca at Box Hill under a stone on 

 May 4th. As far as I am aware this is only the second time that it 

 has been taken in Britain. 



Myrmedonia funesta, Gr. — A specimen was taken running on the 

 ground near an old ash tree at Long Ashton in Somerset, around 

 which a number of A. (D.) fuliginosns % % were crawling. This is I 

 believe only the third record for Somersetshire, of this insect. 



Cldviyer testaceus, Preys. — This species occurred in abundance in 

 nests of A. (C.) flavus under stones at Box Hill on May 4th, many 

 specimens being in cop ; and also with the same ant at Mother Ivy's 

 Bay, N. Cornwall, on July 7th. My friend Mr. Keys tells me he has 

 always found Claviger to be very rare in Cornwall.
