BUTTERFLIES OF ECLEPENS. 131 



angle of these wings, a conspicuous, round, dark spot, which I have 

 never seen reproduced in either species, though the darkness of the 

 inner margin of malvae would almost conceal it if present, and I have 

 one specimen of H. alveiis var. cirsii, from Berisal, in which it is 

 slightly indicated. The ends of the antennae are of an Indian red 

 colour as in alveus, not of the dark brown of malvae. I feel confident 

 that I have also taken, or seen, Pyrameis atalanta, Coenonyrnpha iphis, 

 and Satyrus cordula in this locality, but as I cannot find any note of 

 them I have not added them to the list. 



With regard to certain of the species mentioned, I may remark 

 that both L. euphemus and L. areas are very large and brilliant (the 

 latter adjective, of course, does not refer to the $ areas), and I have 

 never seen specimens from any other locality which approach the areas 

 of the marshy land at the side of the road leading to La Sarraz from 

 Eclepens station ; both species appear here very late, generally at the 

 end of July. The $ s of Melitaea didyma are very varied, some being 

 very close to var. alpina, and others of a transitional form towards the 

 yellow var. occidentalis. M. parthenie and M. dictynna are remarkable 

 for their brightness, Eugonia polychloros, though rather small, for its 

 abundance. The 5 s of ( 'hrysophanus dorilis are dark, and show very 

 little copper. With regard to Apatura iris ab. vde, my experience 

 differs entirely from Mr. Lowe's, every single example I possess being 

 without a trace of the white band on the underside of the hindwings, 

 though in the transitional forms it is often present, though narrowed, 

 and in some specimens it appears on one wing (both above and below), 

 and not on the other ; among my transitional forms is a ? with very 

 little white*. In addition to the forms of A. ilia mentioned, Mr. 

 Muschamp has also taken ab. astasioides and ab. metis in these woods. 

 I think Mr. Lowe must have mistaken Mr. Fison's remark as to his 

 cleodoxa being the only Swiss specimen he knew of, and that it must 

 have been meant to be restricted to Switzerland north of the Alps, 

 since there are several Swiss specimens of this variety, both in 

 Mr. Fison's collection and my own, taken by him in the Gnsons, near 

 Brusio, on the south side of the Maloja, and I also found it to be the 

 commonest form in the Val Maggia, in Ticino, last year, though the 

 ab. intermedia was by no means scarce there. The specimens of 

 Parna&sius apollo from this locality are not only, as Mr. Lowe points 

 out, of the var. pseudonomion, but are also of an ivory whiteness quite 

 remarkable, and correspond, except in point of size, with the var. 

 sibiriea. Aphantopus hyperanthus appears for the most part in the 

 form vidua. Amongst my specimens of Hipparchia briseis is a $ with 

 the light patch near the costal base of the forewings, which is usually 

 considered a distinguishing mark of prieuri, the underside, however, 

 being normal. (I understand that a similar specimen exists in the 

 collection of M. Marcel Rehfous, the secretary of the Geneva Society.) 

 In both sexes the underside of the hindwings occasionally has the 

 ground colour of a pinkish apricot tinge ; the size of the eye-spots on 

 the upperside of the forewings also varies exceedingly, the middle spot

 transitional specimens,, however, the wnite of the underside hindwings is replaced 

 by a band of beautiful dark blue-grey, instead of the whole area being invaded by 

 the chocolate band. The effect is magnificent and startling. — G. W.
