rubi — two or three specimens at rarious places ; on the Bella Tola at about 6,500 ft. 

 Folyommatus virgaurece — males very common in the valley at Yissoye, also in the 

 Turtman Thai and near Zinal, but I only saw a single female ; one male from Vis- 

 soy e is remarkable for being of a yellow colour above : P. Hippothoe, var. Eurybia — 

 this alpine form of Hippothoe, from which it diffei-s in the duller colours of the male, 

 and in the female being almost unicolorous brown above, and greyer beneath ; occun-ed 

 sparingly at Evolena, more commonly at Yissoye, where it occurred with P. virgaurecB, 

 and also on the St. Gothard route, between Andermatt and Amsteg : P. Dorilis, var. 

 suhalpina — two specimens, one at Evolena, the other on the Bella Tola; of the alpine 

 form of Dorilis, which differs from the type in being unicolorous above, and with no 

 redness beneath. Lycmna argyrotoxus {JEgon) — this blue swarmed in the lower part 

 of the Val d'Arolla, rising in crowds from the muddy water in the roads, &c. P. 

 Argus — I secured two specimens from amongst the crowds of the last, and doubtless 

 passed over many more ; will somebody explain why, in two such closely allied species, 

 one {Mgon) should possess, the other (P. Argus) want, the " hornstachel " on the 

 fore tibise : P. Eumedon — rather common at Evolena, and one on the Furka. L. 

 Escheri — two specimens, one in the upper part of the Yal d'Anniviers, coming down 

 from the Col du Torrent, and another at Evolena : L. Corydon — Evolena, Zinal, &c., 

 and one, remarkable for the brightness of its blue, which approaches that of Bellargus 

 {Adonis), at about 6,500 ft. on the Bella Tola : L. Hylas — several at Vissoye, and also 

 occurred at Evolena and in the Val d'Arolla, but only one female : L. Damon— ot\\j 

 one, a male, above Evolena: L. minima {Alsus) — very common ; 1 was surprised to 

 see our little "Bedford blue," so local an insect in England, in the Alps at elevations 

 of 6-7,000 ft., as at Arolla and on the Col du Torrent; also on the Eurka : L. semi- 

 argus (Acis)- — common at Evolena, Vissoye, Arolla, &c. : L. Alcon — rather common 

 at Evolena, and one at Vissoye : L. Arion — occurred at every place we visited. 

 Lionenitis popuU — a single specimen of this fine species in the river-valley at Vissoye 

 sitting on the poplars, and safely secured by Sclatcr. Melitaa Cynthia — Sclater se- 

 cured a single male of this species on the Eurka ; we were pi-obably too early for it 

 elsewhere : M. Aurinia, var. Merope — a single specimen at Arolla, one in the Turtman 

 Thai, and a fine series from the Eurka: 31. cinxia — Vissoye, Evolena, &c., common: 

 M. Phoebe — Evolena, Val d'Arolla, and common about Vissoye and at Sierre. M. 

 didyma — common at Vissoye and Sierre : M. Dicfynna — fairly common at Evolena, 

 Yissoye, Arolla, &c. : M. Athalia — common, Evolena, Yissoye, Arolla, &c. : {M. Par- 

 thenie — one at Lausanne). Argynnis Pales — one at Arolla, and tolerably numerous 

 at high elevations (7-8,000 ft.) on the Col du Torrent and Bella Tola ; also occurred 

 on the Eurka, and between Andermatt and Amsteg ; we did not see the var. Arsilache : 

 A. Dia — one at Sierre : A. Amathnsia — fairly common at Vissoye and Evolena,in damp 

 places along the valleys : A. Ino — with the last : A. Lathonia — one near Vissoye : A. 

 Niobe, var. Eris — one at Vissoye, others on the St. Gothard route ; we did not see 

 Paphia or Adippe : A. Aglaia — rather common. Erebia Epiphron (the form heJamus ?) 

 — sparingly in the higher parts of the Yals d'Herens and d'Anniviers ; also on the 

 Bella Tola, Eurka, and the St. Gothard route : E. Ceto — very common in the valley 

 at Evolena, and a few elsewhere : E. Stygne — this species also abounded at Evolena, 

 but occurred higher than the last, frequenting, not the meadows near the river, but 

 the rocky slopes at the side of the valley ; also sparingly at Arolla, Zinal, in the Val 

 d'Anniviers, and on the St. Gothard; nearly every specimen is a male : E. glacialis,
