170 The Scottish Naturalist. 



Jul}-. Central Europe and Finland. Only a few specimens have occurred 

 in Britain — in Perthshire (Glen Tilt and Rannoch) and Aberdeenshire (Braemar, 

 &c.) It has probably the same habits as pinellus and should be looked for at 

 night. 



[Speculalis H. is somewhat darker, and has the inner-margin narrowly white, 

 and the third portion of the central streak arcuate; permutateUus H.S. is 

 paler, has the inner-margin white, and the third part of the streak sinuate ; 

 luctifereihs H. has in addition a white spot before the tip, and the inner-margin 

 interrupted with white. These species are found on the mountains of Central 

 Europe]. 



2. Central streak undivided. 



MARGAKITELLUS H. — F.-w. acute, yellowish-ferruginous. 

 Central streak dilated and acuminated at the end, reaching 

 nearly to the hind-margin. Cilia unicolorous. Centre of head 

 and thorax white. 9-10 L. 



Var. anglicanus. — F.-w. yellowish-fuscous. 



July, August. Central and Northern Europe. In Britain rather local and 

 commoner in the north than in the south. A common species in the Highlands 

 of Scotland, frequenting damp grassy places in open woods, often in company 

 with Erebia (Ethiops (Blandina). Zeller remarks of the var. that ''the English 

 form is so singular that we might consider it a distinct species." Scottish ex- 

 amples appear to belong to the typical form. 



[The alpine species pyramidellus, Tr., has variegated cilia ; fulgiddlus, H., is 

 cinnamon-coloured, has the inner-margin and a line before the anal angle, white, 

 the central streak touches the hind-margin by two teeth, and is toothed below ; 

 the cilia are variegated, and the hind wings are white; the antennas of the 

 male are serrated.] 



latistrius Hw. — F.-w. elongated acute, greyish-ochreous 

 brown, slightly shining. The white central streak, entire 

 and very slightly dilated beyond the middle, extends to the hind- 

 margin, and is continued in the cilia, where it is obscurely forked. 

 On the hind-margin is a row of more or less distinct black spots. 

 H.-w. pale grey. Antennae of male slightly crenate below the 

 tip. 10-12 L. 



July. A local species. "Western France, Livonia and Britain. In Scotland 

 it is rare, having only been found in Perthshire (once) and in Arran. 



FURCATELiiUS ztt. — F.-w. dark brown. The slender central 

 streak a little dilated beyond the middle, and not reaching the 

 hind-margin, has its lower edge beyond the middle somewhat 

 jagged. Cilia unicolorous, greyish in the male, whitish in the 

 female. H.-w. dark grey in the male, paler and with whitish 

 cilia in the female. 9-10 L.
