THE OCCURRENCE OF ANABOLIA NERVOSA IN JUNE 23 



made for favoured localities : these do not affect the general 

 question. 



Two instances came under notice in the Aviemore 

 district in the summer of 1896. 



In the early part of July, Eminelesia minor at a was fly- 

 ing in worn examples on the slopes of the Cairngorms, and 

 the species seemed to be getting over. But just before I 

 left the district at the end of the month, it began to appear 

 in profusion and perfection at a locality much lower down, 

 not far from Loch-an-Eilan. This is doubtless the locality 

 referred to by Tunaley (" Proc. South Lon. Ent. and Nat. 

 Hist. Soc.," 1897, p. 5), who visited the district that summer 

 from the 29th July. 



The other species was Erebia cethiops. Tunaley (pp. cit. 

 p. 4) says, with regard to this species: "After the 2ist of 

 August the insect was passe in the lower glades, although it 

 was taken on the higher slopes until the 8th of September. 

 Indeed, one could have divided the locality into a series of 

 ascending zones corresponding with the appearance of 

 successive broods extended over a period of six weeks." 

 This seems to give an entirely misleading idea of the 

 sequence of emergence. E. cethiops appeared at one of the 

 highest points of its occurrence near Aviemore as early as 

 2nd July, certainly very much earlier than it did in some of 

 the lower glades there, and also, I am informed, very much 

 earlier than it did near Forres, about sea-level. The term 

 " higher slopes," used in speaking of the Aviemore district, 

 might be misconstrued : E. cethiops is not an inhabitant of 

 the higher slopes of the hills at all, although Dr. Buchanan 

 White's maximum of about 800 feet is, without doubt, some- 

 times exceeded. 



Regarding autumnal insects, a good illustration is given 

 by King ("Trans. Nat. Hist. Soc. of Glasgow," 1886, p. 362), 

 who has recorded a Trichopteron, Halesus auricollis, Pict, 

 from the higher part of Glen Tromie, on 2 7th July. This 

 species is a strictly autumnal one in the lowlands, and has 

 never come under my own notice earlier than September. 



Further instances could be added without difficulty, but, 

 in the absence of written notes regarding them, I refrain 

 from doing so. It may be more useful to give some
