ON SOME NEW AND RARE BRITISH COLLEMBOLA 505 



Gk.nus HETEROMURUS Wankel 



Heteromurus nitidus (Tempi). 



I believe that this species, better known to British entomolo- 

 gists as Templetonia C7'ystallina Lubbock, is common and 

 widely distributed. I have often seen it, but have collected 

 and examined specimens on a few occasions only, these being 

 from Winlaton, county Durham; Matfen and Newcastle, 

 Northumberland ; Ayr and Abbotsford, Scotland. 



Heteromurus cavernicolus (Carp.). 



Sinella cavernicola Carpenter, Irish Naturalist, iv., pp. 25-35, 

 pi. 2, 1895 ; Templetonia cavernicola Carpenter, I.e., vi., 

 p. 229, pi. 2, figs. 2-5, 1897. 



Much interest has recently been aroused amongst ento- 

 mologists by the results of Dr. Norman H. Joy's work with 

 the nests of the various birds and mammals, whereby he 

 discovered several new and rare beetles previously unrecorded 

 as British. The most interesting captures were made by 

 searching the underground nests of the common mole, and 

 Dr. Joy kindly submitted to me a few springtails and wood- 

 lice which he had collected in moles' nests near Reading. 

 Amongst these were the little blind woodlouse Fiatya?-thrus, 

 a dweller in ants' nests ; the minute and blind Sminthuri?ms 

 cceciis, and the cave-species Heteroninrus cavernicolt/s, described 

 by Carpenter in 1895, which is also blind. Two other blind 

 springtails, Lepidocyrhis sp., and what I believe to be Pseudo- 

 sinella cave?-!iannn (Moniez), were also present. 



Mr. Evans has recorded both Pseiidosinella cavernarinn and 

 S7niiithurinvs ccecus from an old limestone mine — a sub- 

 terranean quarry — at Moredun Mains, near Gilmerton, a few 

 miles south of Edinburgh, S. avcvs also occurring in the 

 Mitchelstown Cave. Later Mr. Evans found several examples 

 of -5". ccectis in the nest of the common red ant Myrmica rubj-a 

 in the Clyde district, whilst I have seen it in a nest of an im- 

 ported ant Wasmannia atwipunctata in a hothouse in the Kew 

 Gardens, London. In his latest paper Mr. Evans makes
