St. Nicholas ; it was in every way a well marked example of the 

 second brood. P. rapa?, several examples were taken on the same day, 

 also identical in appearance with the second brood. 



Anthocharis Belia, common ; I took one fine female in the Saas 

 Valley, with the apical spot light grey, but the mark on the disc deep 

 black. 



Colias Edusa, var. Helice, Visp Valley. 



Polyommatus Dorilis, var. subalpina, Visp Valley. 



Lyccena Baton, Visp and Saas Valleys. L. Icarus, var. Icarinus. 

 L. Corydon, Visp Valley. L. Damon, near Stalden, Visp Valley. L. 

 Sebrus, I cannot quite make up my mind about this insect, the speci- 

 mens caught, which were of both sexes, resemble Sebrus exactly in 

 size, but in colour, and in the width of the black border, the males are 

 very similar to semiargus, much more so than in the type examples of 

 Sebrus in my cabinet ; it may be a small race of semiargus : of course, 

 this latter was abundant. L. Cyllarus, common in one field in the 

 Saas Valley amongst Vicia onobrychioides ; that field could not easily 

 be forgotten, it was gay with flowers, 3Iachaon and Podalirius were 

 abundant, so also were Apollo, Hyale, Athalia, Phoebe, Euphrosyne, and 

 many other butterflies ; every now and then an Ascalaphus, with its 

 straight undeviating flight, passed over head, whilst the dark velvet- 

 looking Erebia Evias flitted over the grass, or a large black-winged 

 Bombus settled on the blossoms. Such was the near scene, but the 

 picture is very incomplete unless we remember that the Monte Eosa 

 range bounds the Valley above, and that downwards we look on the 

 snows of the Bernese Oberland. Amongst the Lycance taken were 

 specimens of JEgon, semiargus, and Arion, all varying on one uniform 

 plan, namely, the posterior half of the wing shaded deeply with black, 

 gradually passing into blue, but the black margin filling quite the half 

 of both upper and lower wings. 



Nemeobius Lucina. 



Vanessa comma, Io, and Antiopa, all worn, and evidently hiber- 

 nated ; larvae of Io were also common at the same time on the nettles. 

 V. urticce was common, and in fine condition. 



Melitcea Cinxia, Visp Valley. 



Aryynnis Dia. 



Erebia Goante, Visp Valley. 



(Eneis Aello was common near Saas-im-Grund, in one stony part 

 of the Valley ; some fell to my lot, but my companion, who was fleeter 

 of foot than myself, caught several. 



Pararye Meycera.
