MYRMICA. 125 



male and female pupae in a colony under a stone on a mountain 

 at Rannoch on June 14th, 1911, and also in another situated under 

 a piece of timber on the sandy bank of the Nethy, at Nethy Bridge 

 on June 21st, 1911, which I took home with some of their workers, 

 and from which the winged forms emerged in July 32 . 



Wasmann 17 records finding, in August, 1891, in a colony of this 

 species at Arlbergpass at a height of 1800 metres, an individual 

 in which the shape of the thorax and size of the body was that of a 

 worker, the gaster however being as well developed as that of a 

 fertilized female, and there did not appear to be any other queen, 

 or female, in the nest. 



The following myrmecophiles have occurred with this species in 

 Britain : 



Coleoptera : Atemeles emarginatus Pk., and Drusilla canaliculata 

 F. 34 . 



Collembola : Cyphodeirus ( = Beckia) albinos Nic. 



Crustacea : Platyartlirus hoffmanseggi Brandt.
