entirely lacking, and are not even marked by the usual black 

 lines. Half of nervure six is missing in fig. 10. 



Variations of the lower wing. — The central spot and lower spot 

 in the yellow band are absent in fig. 6. The same specimen 

 shows also the row of crescents round the hind margin greatly 

 reduced in size, and brownish yellow instead of clear whitish 

 yellow. Figure 7 shows a variation often present in ab. virgata. 

 The central yellow fascia is continued almost to the base of the 

 wing by an irregular oblong patch. A similar extension of the 

 corresponding band on the under side is not infrequently found 

 on the same specimens. It occurs also when the upper side does 

 not correspond (see fig. 9). 



Variations of the under side. — Black bands are sometimes 

 found near the inner margin and costa, corresponding to those 

 on the upper side. The pale yellow fascia on the under wing is 

 often powdered with black scales. In fig. 8 it lacks the outer 

 black line. This variety illustrates a tendency common to many 

 continental members of this genus, in which the black markings 

 are restricted to the basal portion of the under wing. 



Variation of the antennce. — I have a specimen (not figured) in 

 which the antennae are noticeably shorter than usual. 



Pathological aberrations. — In fig. 2 the costa is straight on 

 one side and curved on the other. Figure 10 is that of a specimen 

 which I watched emerging from the pupa. The wings lack scales 

 over most of their area, but the fringes are all perfect. 



ENTOMOLOGICAL NOTES FEOM SWITZEELAND. 

 By Gerard H. Gurney. 



The following short notes on my captures in Switzerland last 

 summer were roughly jotted down in my note-book everyday, 

 and may, perhaps, be of interest to others who were also able to 

 spend a few weeks in that wonderful countrj'. During an all too 

 short six weeks, spent mostly in, and near, the Ehone Valley, I 

 identified one hundred and twelve species of butterflies, irre- 

 spective of the moths, which, out of a possible one hundred and 

 eighty-eight, is a large percentage. 



I arrived at Aigle, at the entrance, or beginning rather, of 

 the Ehone Valley, on Saturday, June 24th, and stayed at the 

 Grand Hotel, about a mile from the town, at the side of the valley 

 of the "Grand Eau," which proved to be a capital collecting 

 ground. 



The weather for a week previous to our arrival had been fine 

 and hot, but the very day I got there it clouded over, and the next 

 two days were wet and dull — rather a damper to one's enthusiasm 

 on first getting out. However, Tuesday the 27th broke fine and
