 Alps (' Alpenblumen,' p. 89).

 and S, do.) at Bremen. MacLeod observed 2 moths, 3 short-tongued Hymenoptera, 

 3 beetles, and a Neuropterid in Flanders (Bot. Jaarb. Dodonaea, Ghent, vi, 1894, 

 p. 291). 



Burkill records the following for the coast of Yorkshire, all skg. (' Fertlsn. of 

 Spring Fls.'). — 



A. Coleoptera. i. Lathrimaeum atrocephalum (Ty//. ; 2. Tachyporus chryso- 

 melinus L. B. Diptera. Muscidae : 3. Cecidomyia sp. and 3 other small flies.

976. C. oppositifolium L. (Herm. Miiller,' Fertilisation,' p. 247, ' Weit. Beob.,' 

 I, p. 298.) — Hermann Miiller states that the hermaphrodite flowers of this species 

 are protogynous with persistent stigmas. In other respects their mechanism agrees 

 with that of C. alternifolium, though they and the bracts surrounding them are 

 smaller and less conspicuously coloured, besides which automatic self-pollination 

 is easy. Kobus describes the species as andromonoecious, developing numerous 

 purely male flowers when it grows in thick clumps (D. bot. Monatsschr., Arnstadt, i, 

 1883, p. 74). 



Burkill ('Fertlsn. of Spring Fls.') remarks that the species is gynodioecious 

 on the Yorkshire coast, and that female plants are common throughout the whole 

 district. They are readily recognized by their green flowers, for the golden-yellow 

 colour of the hermaphrodite blossoms is almost entirely absent. Female flowers 

 are also smaller than hermaphrodite ones. No trace of pollen is to be found in 

 them : even anthers are almost completely absent, and any which may remain are 

 functionless. 



Visitors. — Herm. Miiller observed 2 beetles (Coccinella bipunctata L. and C. 

 impustulata Z.) and 2 flies (Chlorops scalaris Mg. and Musca domestica L.) seeking 

 the drops of nectar which are distinctly visible. 



Burkill observed the following on the Yorkshire coast. — 



A. Araneida. i. i sp., lying in wait. B. CoUembola. 2. Lepidocyrtus sp. 

 C. Diptera. {a) Muscidae: 3. Lonchoptera sp. ; 4. Sepsis nigripes Mg. [b) Myceto- 

 philidae: 5. Exechia sp. ; 6. Sciara sp. (.:) Syrphidae: 7. Melanostoma quadri- 

 maculata Verrall. (d) Tipulidae : 8. Chironomus sp. D. Hymenoptera. Ichneu- 

 monidae: 9. One small sp. E. Thysanoptera. 10. Thrips sp. 



In Dumfriesshire, an Ichneumonid, 3 Muscids, and a beetle have been recorded 

 (Scott-Elliot, 'Flora of Dumfriesshire,' p. 72).
