Loew (Silesia) saw a wasp, Vespa media Retz. 5, skg. ('Beitrage,' p. 33); 

 ind Warnstorf (Brandenburg) numerous bees and humble-bees. MacLeod (Flanders) 

 aoticed 5 long-tongued bees, 4 short-tongued bees, 2 wasps, an ant, 3 hover-flies, 

 ; other flies, 5 beetles, and a few Lepidoptera (Bot. Jaarb. Dodonaea, Ghent, vi, 1894, 

 ). 317). Plateau (Belgium) saw Apis, Bombus hypnorum Z., B. lapidarius Z. ; and 

 .lso numerous moths, e. g. Scoliopterys libatrix Z. 



In Dumfriesshire, Apis (common), 3 humble-bees, and 2 hover-flies were 

 ecorded (Scott-Elliot, ' Flora of Dumfriesshire,' p. 55).

Visitors. Alf ken observed the following bees at Bremen : all skg. and po-cltg. 

 1. Apis mellifica Z. , freq.; 2. Bombus jonellus K. 5; 3. B. lucorum L. 5; 

 .. B. muscorum F. 5; 5. Podalirius acervorum Z. 5. 



842. R. saxatilis L. Hermann Mtiller (' Alpenblumen,' pp. 215-16) describes 

 ie white flowers of this species as protogynous, with persistent stigmas. The 

 .amens are about 40 in number. When the flowers open the stigmas are already 

 laiure : the outer stamens now become erect, and their anthers dehisce, while the 

 iner ones remain curved inwards, so that the stigmas are for a time protected 

 gainst automatic self-pollination. As the petals incline together above the nectar- 

 icreting receptacle only a small passage of access is left. Visitors at first effect 

 ross-pollination, subsequently self-pollination as well. The latter always takes place 

 utomatically should insect-visits fail (Mtiller, Warming). 



Visitors. Herm. Miiller observed 3 bees and an Empid in Switzerland.
