A SUMMER HOLIDAY IN BELGIUM, GERMANY AND SWITZERLAND. 295 



seemed in first rate condition. In the afternoon a terrific thunder- 

 storm wetted me to the skin, although standing under the thickly leaved 

 trees of the wood, and drove me back to the hotel at Virton to change. 



Though a little rain fell early, July 7th was quite a nice day. I 

 walked some distance along the road towards St. Leger to the well- 

 known Vallee des Rabais, which is several kilometres in extent. In 

 the woods to the left of the main road through the Vallee I took a 

 number of male Chrysuphanus vinjanreae, as well as Nordiiiannia ilicis, 

 Brenthis dia, Anfi/nnis paplda, A. ajilaia, Melitaea athalia, a,nd C'ljaniris 

 seiiiiaiyiis (acis), besides being unable to capture Pvli/tjonia c-album, 

 Apatura iris, A. ilia and Liinenitis sibijlla. Later in the day in the 

 same valley I took both sexes of C. hippotlw'e, a fine just-emerged 

 specimen of Hesperia carthami, and an interesting fritillary which I 

 have not yet identified. I think that this valley would prove a very 

 good collecting ground to anyone with plenty of patience, in fact the 

 whole district between St. Leger and Ecouviez on the French frontier 

 would probably repay any one who wanted to have an economical 

 holiday, and who did not mind roughing it a bit. Between these two 

 places no less than 78 species of the European Ehopalocera are to be 

 taken, the best stations to work from being Ethe, Virton and 

 Lamorteau, as well as Habay on the mainline near Marbehan, for the 

 Foret d'Aulier. The Vallee des Kabais, however, is rather an exhaust- 

 ing place to work in a single day on account of the very damp parts, 

 which border the various natural streams flowing down it. To a 

 botanist this valley would no doubt prove a "happy hunting-ground." 



After spending a comfortable night in the train, early on the 

 morning of July 8th, I reached Freiburg in Baden in time for 

 breakfast. To any one who wishes to work the Black Forest district 

 with Freiburg as a centre I can thoroughly recommend the Hotel 

 Pension Bellevue in the Gunterstall Strasse. As soon as possible I 

 caught a train from the Freiburg Wierhe Station for Hinterzarten 

 which was reached after about an hour's run. When I entered the 

 well-known ground to the north of the railway, I found Colias palaeno 

 var. eurupoine, both sexes, and Coenonyuipha tijphon {danm) in abundance, 

 as well as Brenthis selene (2nd brood I presume), and Diacrisia sanio 

 {ntssula} in splendid condition. Unfortunately it came on to rain 

 persistently about the middle of the day, and although it cleared 

 later it spoilt the day. Owing to the previous heavy rains the " moss " 

 was like a quagmire except along the regular path across it. This 

 -made the day's work very exhausting, as one walked up to one's boot- 

 tops in water most of the time, and I was glad to return to Freiburg 

 for dinner feeling very tired though very contented with the day's 

 work. 



On the next day, July 9th, I collected in the Mooswald, an extensive 

 and fine wood, three miles out from Freiburg in a westerly direction, 

 and which must be reached on foot, though one does not regret the 

 tramp. In this wood I took several picked specimens of L. sibylla, very 

 large P. c-albmii, A. adippe, Araschnia leiana var. prorsa, and Brenthis 

 dia with a few B. daphne (going over) and five Apatura iris audi A. ilia. 

 Along the road I took several Sesia stellataruw. The day was a 

 very fine and hot one. 



July 10th found me at Wasen Weiler station, on the line between 

 Freiburg and Alt-Breisach, for a walk up and along the Kaiserstuhl, a
