LÉPIDOPTÉROLOGIE COMPAREE I/I 



identical. And this view is strengthened by an examination 

 of the séries in the British Muséum collection spaciously labelled 

 " Germany ", among which is one from Frey more particularised 

 as from " Bremen ". Superficially, their colour is quite différent 

 from the warm dark brown of the Lancashire moss spécimens, 

 though on the under side the abundant markings of some are 

 suggestive of the best of our southern form, viz., that which is 

 found in Delamere Forest. I notice, also, that the brown colour 

 of the Weesen typical tïphon is altogether more pamphilus-Wke 

 than that of our Yorkshire type, and the heavily eyed transitas 

 ad philoxenus are a much less umber brown. 



The beautiful, bright var. rhodopensis, Elwes, from the Balkans 

 hâve been referred since their discovery on the Rilo Dagh, I believe 

 rightly, to the nearly allied species, of the further East, C. sym- 

 phita. 



The Bionomics of CŒNONYMPHA TIPHON 



The following is an extract from Zeller's account of C. tiphon 

 in its early phases under natural conditions : 



" The larva which lives exposed and rests rather high on the 

 grass-blades, is tolerably easy to observe; still easier to capture with 

 the net; but that nothing concerning it has been made known is, 

 doubtless, because the collectors leave unobserved butterfly larvae, 

 since they obtain the imagos more easily by the net than by 

 breeding. 



I found on June 25th, when the butterflies were flyiîig in 

 great abundance in an open bog, two fairly grown larvae, resting 

 on the long narrow leaves of a bog Carex growing in tufts. They 

 were on such a sod that, although the leaves had been eut, 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 they immediately 

 dropped into the moss on being disturbed, where they remained
