Just over the waterfall at the back of this Alp Erehia yoryc loved 

 to disport itself, settling in the blazing sun on the hot rocks above the 

 stream with its wings rather more than half open and head upwards, 

 so that the full rays would shine direct upon it ; this species, though 

 often difficult to take, was not rare, but it did not frequent the Alp to 

 any extent, though I took it all over the district near the streams 

 among the rocky and broken ground. On the Bortel Alp and the 

 mountain slopes E. lappona was the commonest of the genus, next to 

 this came einphrou in the higher altitudes, but in the lower districts 

 ligea was far away the most frequent of the group ; of nielampus I 

 only took a couple of specimens, and tyndarus, though in excellent 

 condition, w^as not as common as I should have expected. I captured 

 a nice series of mnestra, bvxt goante was quite rare, but perhaps late 

 in the season as it was, the species was just beginning to emerge, as a 

 week and a fortnight later I found it plentifully at Macugnaga, and 

 also at Saas Fee ; ceto was probably going over, as only a short series 

 fell to my net, whilst of stygne I only took a single specimen with an 

 excessively black under- side. 



There are one or two points of interest that I noted in the 

 Erehias — there was quite a high per centage of gorge without any 

 spots at all on the upper surface, and this was usually repeated below 

 as well ; ligea and its var. adyte occurred somewhat indiscriminately 

 together ; epiphron also had a strong tendency to develop spotless 

 aberrations, and I took some specimens without any spots whatever ; 

 of the one species that I especially wanted, viz., gJaciaiis, I did not see a 

 single example, and I learned from other entomologists in the hotel 

 that it had scarcely been seen at all this season. 



Ccenonympha arcania was very common in its form dartviniana, 

 the specimens being of an unusually bright fulvous. Lithosia liiri- 

 deola I found both at rest and on the wing, evidently recently emerged, 

 whilst Emydia crlbruni v. ptmctigera was also taken at rest. Macro- 

 glossa steUatarum was busy as usual in the hot sun, whilst in the 

 valleys I fovmd Anthrocera lonicerx and transalpina fairly abundant, 

 filipendulx was rare, and I took a couple of examples of carnioUca v. 

 hedysari. The only species of Ino that I saw or took was a pair of 

 statices v. heydenreichii. 



Anthrocera achilleas was not uncommon near the haunts of P. 

 lycidas, whilst hign on the way to the Bortel Alp some beautifully blue
