The male of this elegant species was unknown to Nylander when 

 he described the worker and female in 1846 1 , and Smith states, in 

 1855 5 , that it is described by himself for the first time, although he 

 quotes Curtis' paper in which the latter described the male, as well 

 as the female and worker, from a colony under a stone on a heath 

 near Bournemouth, under the name of Myrmica perelegans 3 . 



M. sulcinodis chiefly nests under stones, its colonies being only 

 of moderate size, and its habits appear to be intermediate between 

 those of M. ruginodis and M . scabrinodis. 



Farren-White points out that it has been said to raise a mound 

 like the turf dwellings of Donisthorpea flava, but according to his 

 experience its nest is but very slightly elevated above the surface 

 of the soil 16 . 



Nylander 2 and Mayr 4 both give mountains for its habitat ; and 

 Forel 9 and Andre 13 affirm that it is exclusively an alpine species. 

 The former observer says that it ranges to nearly as high an 

 altitude as does Formica fusca, and is abundant in the highest 

 parts of the Engadine, nesting under stones on high pastures up 

 to the region of the fir trees 9 . 



On May 23rd and 25th, 1914, Dr. Chapman found workers 

 attending the larvae of the " Blue Butterfly " (Polyommatus 

 eros Ochs.), at Le Lautaret at an elevation of 7000 ft. odd. 



Its habits are certainly different in the British Isles it is true 

 that I have found it under stones on mountains at Rannoch 32 and 

 Braemar 28 , though only at a moderate height, but it is more 

 abundant down south, on heaths and commons, such as at Woking, 

 Bournemouth, and in the New Forest. The sexes swarm in August 

 and September ; Saunders records finding an isolated female, the 

 only time he ever met with this sex, running on the ground at 

 Chobham in August, 1885 14 , and I took dealated females in sand- 

 pits in the New Forest on May 21st and June 7th, 1908. I found
