50 THE ENTOMOLOGIST’S RECORD. 
5.—Full-fed larve of Myelois cribrella may now be found in 
dead thistle stems. They are most partial to those of Cntcus lanceo- 
latus. 
6.—Larve of Gelechia tricolorella should be sought for in spun 
together tips of Stellaria holostea. 
7.—Cases containing larvee of Narycia (Xysmatodoma) melanella are 
to be found by diligently searching the lichen-covered trunks of various 
trees. 
8.—Brephos parthenias flies freely in bright sunshine round the 
tops of birch trees, in which position it is difficult to obtain, but by 
standing in an open space between the trees, it is readily secured, as 
in passing from tree to tree it comes considerably nearer the earth. 
9.—Larve of Bucculatrix cristatella ave to be found on leaves of 
Achillea millefolium. Care must be taken not to shake the plants or the 
larvee will fall to the ground, and then are not easily to be detected. 
Later on, the most beautiful white cocoons may be found spun on the 
leaves and stems of the food-plant. 
10.—Larve of Coleophora lineolea, are now blotching leaves of 
Ballota nigra and Stachys sylvatica. ‘They are also found in gardens 
on a species of Stachys commonly called ‘‘ Lamb’s ear.” 
N.B.—Similar series of ‘‘ Practical Hints ’’ for these months are to 
be found in the preceding volumes. 
YOTES ON COLLECTING, Ete. 
Butterriies oF THE RuonE vattey.—lI have been greatly interested 
by Mr. Wheeler’s articles ‘‘Three seasons among the Swiss butterflies,” 
for the localities he speaks of have been wel] known to me for the last 
fifteen years and more. I think that I was the first to discover 
Polyommatus tolas at Sierre (this was in 1889), and I have since given 
the locality to several friends. For particulars I informed Mr. Fison 
of it, and he afterwards told me that he had taken three specimens 
there. The curious part of the story is that I got three specimens too, 
and no more, and that, both mine and Mr. Fison’s were all taken at 
the ‘‘famous corner,’’ where there is, in fact, only a single bush of 
Colutea. Ihave several times looked elsewhere for this insect but 
though I could find its food-plant, I could never discover the insect 
itself at any other place. Iam glad to find that it does, as I felt sure 
it must, occur, elsewhere. Mr. Wheeler is quite right about the best 
part of the Pfynwald for butterflies, but as regards Apatura ilia I have 
always found it most abundant alongside that long row of poplars just 
on the Sierre side of Pfyn. I once in July found Cyaniris argiolus in 
some abundance on bushes in a meadow near Pfyn, on the Leuk side, 
and I have generally found a few Lycaena arion between the Rhone 
Bridge and Pfyn. I never could find Cupido sebrus at all, I am sorry 
to say. I once got a fine lot of Argynnis daphne and of Chrysophanus 
gordius on the zigzags going up to the Martigny bourg. Mr. Fison 
was kind enough to tell me of this locality for C. gordius, but the 
specimens taken there cannot be compared either for size or colour, 
with those found on the Italian side of the Simplon. If Mr. Wheeler 
should visit the Rhone valley again, [ recommend him to go to Zermatt 
and try the Riffel Alp about mid-July. He will find amongst other | 
things Melitaea var. merope and M. cynthia abundant. Colias palaeno
