1653. C. rubra L. This South European species opens its heads at Innsbruck, 

 according to Kerner, about 7-8 a.m., closing them again about 6-7 p.m. 



Visitors. Schletterer and von Dalla Torre (Tyrol) observed 3 bees 1. An- 

 drena albicrus K. 5 and S; 2. Halictus sexnotatus K. $; 3. Prosopis annulata L. 

 $ and S. 



1654. C. aurea Reichb. ( = Hieracium aureum Scop., Leontodon aurea Z.). 

 (Herm. Miiller, ' Alpenblumen,' pp. 462-3.) In this species there are usually over 100 

 florets in the head, which expands in the sunshine to a diameter of 35-60 mm. 

 The anther-cylinder projects as much as 6-7 mm. from the corolla-tube, and in 

 the second stage of anthesis the style extends 5^ mm. further. The stylar 

 branches are 3 mm. long, and curve away from each other, though only in 

 individual cases to such an extent as to render automatic self-pollination possible. 



Visitors. The following were recorded by the observers, and for the localities 

 stated. 



Herm. Miiller (Alps), 2 beetles, 4 flies, 3 Hymenoptera, and 19 Lepidoptera. 

 Loew (Switzerland) (' Beitrage,' p. 58), a Bombyliid (Nemeophila plantaginis Z.), 

 a Noctuid moth (Agrotis ocellina S.-V.), and a butterfly (Argynnis selene S.-V.).

 (Tyrol), 3 bees 1. Bombus mastrucatus Gerst. ; 2. Halictus levis K. ( = H. fulvicornis 

 K.) ; 3. H. smeathmanellus K. 



It is noteworthy that the orange-red florets are chiefly visited by red butterflies 

 (Argynnis, Melitaea, species of Polyommatus). (C/. Senecio abrotanifolius and 

 Hieracium aurantiacum, and the note in Vol. I, p. 144.)
