PLEBEIUS ARGUS. 239 



Hill (Trimen), on the chalk downs of the Maidstone district (Goodwin), 

 and Eynsford (Battley), and in a rough field at Kingsdown (Cardew). It 

 is recorded on a grassy slope close to the sea, near Swanage, where it 

 occurs with Agriades coridon, Aricia astrarche, Polyommatus icarus, 

 Hipparchia semele, Pararge megaera, and hundreds of Thymelicus acteon, 

 whilst it is also very abundant all over the Lizard promontory, much 

 more so than Polyom matus icarus (Eiding). It swarms in the Isle of 

 Portland, away from heath, amongst long grass on which it usually 

 passes the night (Kichardson). It occurs on the chalk near Chichester 

 (Sperring), and also at Guildford, but is much more abundant on the 

 grassy heaths at Witley (Champion). It abounds on the wild heaths 

 on the outskirts of the New Forest, and, indeed, on heaths throughout 

 the whole county of Hants, an extension, as it were, of those heaths in 

 Surrey, oh the Bagshot Sand, on which it is also so abundant. It is 

 to be found in great numbers on the heaths at Lyndhurst, at Oxshott, 

 Woking, Newbury, as well as the heaths of the Isle of Purbeck. It 

 also occurs on heaths in the King's Lynn district (Atmore), on a 

 breezy heath towards Broadwater Forest near Tunbridge Wells 

 (Tremayne); it swarmed in the middle of June 1868, near Tunbridge, 

 occurring in thousands (Cox); is common among Erica cinerea at 

 Woolacombe (Longstaff); abundant on the common on the east side of 

 the road at Ripley (Turner); also on the Gaddon Down heath near 

 Cullompton (Angus); on a common near Storrington (Bird), etc. 

 Ellis also records it as occurring among the heather and gorse on 

 Bidston Hill, and Day, that it swarms on the sandhills at Abersoch ; 

 on June 11th, 1893, at Abersoch, it swarmed on the heaths and sand- 

 hills, where the specimens are much larger than in Delamere Forest, 

 or on the Lancashire mosses. It is noted as plentiful in the open boggy 

 places of W 7 oolmer Forest (Barrett), local in marshy places in the 

 Isle of Wight (Pristo), whilst the beautiful local race masseyi is found 

 in the wet mosses of Witherslack, that cross the borders of North Lan- 

 cashire and Westmorland ; Massey says that the insect flies only in the 

 wettest part of the mosses. It may be here noted that Teich records 

 it as a " moorland " insect in the Riga district, but its habitats abroad 

 are even more varied than in Britain, and Nolcken says, that it occurs 

 generally in the Baltic Provinces on heaths and in wood-clearings. 

 In Belgium it is widely distributed but locally abundant, occurring 

 commonly in wood -clearings at Beez, and in waste places near 

 Hannut, etc. In Germany, it occurs from sea-level to the tree-limit, 

 haunting clearings, heaths, meadows in woods, and mountain -meadows 

 (Speyer). The choice of heaths appears to be as frequent in Germany 

 as in Britain ; thus we find it recorded as being everywhere frequent 

 in Pomerania where Calluna vulgaris grows, on the outskirts of open 

 pinewoods at Warsaw, Carolinenhorst, etc., by roadsides at Nemitz, 

 etc. (Hering), everywhere choosing dry situations, e.g., sunny clearings 

 on the edge of pinew T oods, or sunny meadow slopes (Spormann); in 

 Mecklenburg, it prefers the dry, sandy, w 7 arm heaths of the Buchholz, at 

 Schwerin, although found singly on the neighbouring marshy districts, 

 w 7 hilst at Parchim it also haunts the heaths (Gillmer) ; it is abundant 

 on the heath and sandy district between Schwerin and Ludwigslust, 

 and in a similar situation in the forest of Mestlin, but occurs not 

 rarely on the moss near Tarzow (Schmidt); it is also very common on 

 the Wesloe moss at Liibeck,as also on the heath at Paling (Tessmann).
