452 REV. A. MILES MOSS ON THE BUTTERFLIES OF SWITZERLAND. 
I now find that it is the next species L. argus, and I should have 
been glad of a series. 
Amongst many others of which we have already spoken, and 
which I had no time to pay further attention to, I must not fail in 
conclusion to mention the Coppers. Some twenty of these gaudy 
little creatures were secured on the hill slope by a small rivulet 
between Findeln and Zermatt, and many others seen. Those 
I took were all together, and were all males, and I went away with 
the impression that they were all Polyommatus virgaurae. On 
closer investigation I found that I had undoubtedly got two species. 
Eight or nine were virgaurae, and the rest I have now come to the 
conclusion are not rutilus , but a local Alpine form of hippothoe 
without the purple sheen, which goes by the name of eurybia. 
I had again taken an underside variety, the spots on the hind 
wings on one side only being elongated into narrow radial streaks. 
To deal with the Moths on the present occasion would, I fear, 
make my paper disproportionately long and perhaps tedious. I will 
therefore content myself by merely exhibiting a few of the rarities 
which I took. 
I conclude by confidently recommending both Yillars and 
Zermatt as excellent holiday resorts for the lepidopterist.
