50 THE entomologist's eecord. 



5. — Full-fed larvae of Myelois cribrella may now be found in 

 dead thistle stems. They are most partial to those of Cnicus lanceo- 

 latus. 



6. — Larvae of Gelechia tricolorella should be sought for in spun 

 together tips of Stellaria holostea. 



7. — Cases containing larvte of Narycia (Xysmatodoma) melanella are 

 to be found by diligently searching the lichen-covered trunks of various 

 trees. 



8. — BrepJws 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. — Larvffi of Biiccnlatrix cristatella are to be found on leaves of 

 Achillea millefolium. Care must be taken not to shake the plants or the 

 larvfB 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, — Larvffi of Coleoplwra lineolea, are now blotching leaves of 

 Ballota nigra and Stachys sylratica. 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.

BuTTEEFLiES OF THE Ehone VALLEY. — I havc been greatly interested 

 by Mr. Wheeler's articles "Three seasons among the Swiss butterflies," 

 for the localities he speaks of have been well known to me for the last 

 fifteen years and more. I think that I was the first to discover 

 Polyo)inimtus 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. I have 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. I am glad to find that it does, as I felt sure 

 it must, occur, elsewhere. Mr. Wheeler is quite right about the best 

 part of thePfynwald 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 aryiolm in 

 some abundance on bushes in a meadow near Pfyn, on the Leuk side, 

 and I have generally found a feAV Lycaena avion between the Rhone 

 Bridge and Pfyn. I never could find Cupido sebnts at all, I am sorry 

 to say. I once got a fine lot of Aryyyinis daphne and of Chrysopjhanus 

 gordius on the zigzags going up to the Martigny bourg. Mr. Fison 

 was kind enough to tell me of this locality for C. yordius, 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 Ehone valley again, I recommend him to go to Zermatt 

 and try the Eiffel Alp about mid-July. He will find amongst other 

 things Melitaea var. merope and M. cyntkia abundant. Colias palaeno
