The following are recorded by the observers, and for the localities stated. — 



Knuth (Gliicksburg), the humble-bee Bombus sylvarum Z. 5, skg. Loew 

 (Brandenburg), the hover-fly Melithreptus scriptus Z., skg. (' Beitrage,' p. 41): 

 (Berlin Botanic Garden), the Muscid Lucilia caesar Z., and the Syrphid Syritta 

 l)ipiens Z. MacLeod (Flanders), the honey-bee, 6 Syrphids, 2 Muscids, 5 

 Lepidoptera, and a Neuropterid (Bot. Jaarb. Dodonaea, Ghent, v, 1893, p. 364, vi, 

 1894, p. 371). H. de Vries (Netherlands), the humble-bee Bombus agrorum F. 5 

 (Ned. Kruidk. Arch., Nijmegen, 2 Ser., 2 Dee), 1875). E. D. Marquard (Cornwall), 

 2 bees — Andrena fulvicrus K., and A. pilipes Rossi. Scott-Elliot (Dumfriesshire), 

 2 humble-bees, 5 hover-flies, several Muscids, 3 Lepidoptera, and several beetles 

 (' Flora of Dumfriesshire,' p. 135). 



2229. M. gentilis L. (Schulz, 'Beitrage,' II, pp. 126-7; Kirchner, 'Flora v. 

 Stuttgart,' p. 609; Mowes, Bot. Jahrb., Leipzig, iv, 1883, pp. 189 et seq.) — In this 

 species Mowes found the same difference in the respective sizes of hermaphrodite and 

 female (gynodioecious) flowers as in the two preceding ones. As these, however, are 

 sterile, he does not consider M. gentilis a species, but a hybrid between M. aquaticaZ. 

 and M. arvensis Z. Schulz says that the female form sometimes predominates (e. g. 

 in Thuringia), or is even the only one present. He also states that flowers with normal 

 stamens are occasionally to be found. 



2230. M. rotundifolia Huds. — Schulz ('Beitrage,' II, p. 195) says that this 

 species occurs gynomonoeciously and gynodioeciously with protandrous herma- 

 phrodite flowers. 



2231. M. sylvestris L. (Herm. Miiller, ' Alpenblumen,' p. 325; Schulz,
