26o LEPIDOPTERA. 



In the Entovwlogists' Monthly Magazine for 1865 and 1869, 

 Professor Zeller is quoted. " This species is common on all 

 the bogs and peaty places of the Mark Brandenburg, of 

 Silesia (at Glogau), and of the province of Posen. The 

 larva, which lives exposed, and rests rather high on the 

 grass-leaves, is tolerably easy to observe, but easier to 

 capture " (sweep up) " with the net. On June 25th, when 

 the butterflies were already flying in abundance, I found in 

 an open bog two tolerably grown larvse resting on the long 

 narrow leaves of a bog Carcx growing in tufts. They were 

 on such a sod that, although the leaves required to be cut, it 

 could easily be kept fresh, and they fed on it for more than 

 three weeks. They fed by day resting on the leaves, yet 

 immediately dropped into the moss on being disturbed, where 

 they remained, lying rolled up, for some time." " It is 

 possible that with us the larva may feed on Bhyncliospora, 

 but this plant I have as yet found on only one peat-swamp, 

 which I have never visited in summer, while the butterfly 

 occurs in all our peaty moors and meadows ; so I imagine 

 that the larvae will feed freely on Carcx, and will not die of 

 hunger if supplied with any of the sharp grasses that grow on 

 moors." 



Pupa bright green with brown streaks on the edges and 

 centre of the wing-covers and at the tip of the tail (Buckler). 

 Professor Zeller describes it " pale green, more transparent on 

 the thoracic shield than on the wing-cases ; abdomen more 

 whitish and quite opaque ; the dorsal margin of the wing- 

 cases is bounded by a fine whitish line, and outside this by a 

 still finer brown line. Suspended freely by the tail to a stem 

 or leaf of the food plant, high up. 



The butterfly is rather lively and active, frequenting boggy 

 and swampy places, but also delighting in rough breezy hill- 

 sides, especially their damp hollows, resting near the ground 

 among the grasses, and delighting to dance up and down 

 about them, but flying with some vigour when alarmed.
