478 BRITISH LEPIDOPTERA. 



whilst Borkhausen records it from the forest near Darmstadt. Double- 

 day notes it as abounding in moist meadows near Monk's Wood, 

 and Barrett that it occurs in Shropshire, in some rough fields on the 

 top of Wenlock Edge. It abounds on the slopes of the pine woods at 

 the summit of the Mendel Pass, and we have taken it on the slopes 

 below the glacier La Meije, opposite La Grave, in Dauphine, and on 

 the rocky slopes above Lac Bourget in Savoy. Above Gresy-sur- 

 Aix (near Aix-les-Bains) it occurs in a saintfoin meadow, and at 

 Courmayeur (Piedmont), in a hollow below the pine woods on Mont 

 Courmet, so that its habitats are varied enough. Zeller gives as its 

 habitat at Glogau, open places amongst birch and fir woods, on 

 hillocky ground, where flowers are numerous ; Peyerimhoff notes 

 it in the wood clearings, both in the mountains and plains of Alsace, 

 whilst Demaison says that A. lonicerae is found, in the woods about 

 Kheims, A. trifolii being confined to a marshy habitat. 



Time of appearance.— The time of appearance varies according to 

 the season, from mid-June in 1893 to late July in 1888. Maddison 

 notes it as appearing usually in July and August at Filey, Porritt in 

 July, 1870, also at Filey, Lowe in August at Dorchester, Raynor 

 in August at Swanage, and Bostock in June, 1887, at the Land's End. 

 On July 16th, 1897, at Filey, freshly-emerged imagines were drying 

 their wings ; at the same time, there were numbers of pupse spun up 

 on the grass-stems, and a few still in the larval stage ; the pupae were 

 very abundant, but confined to a comparatively small area (Maddison). 

 Generally the larvse have all pupated in the York district by June 

 15th-20th, and the imagines appear on the wing from the end of the 

 month to the second week in July (S. Walker). The following are 

 actual dates of capture : June 16th, 1860, larvffi only, a late year,
