Alfken noticed 2 bees (Andrena gwynana K. 5 and J, skg., and A. parvula K. 5 

 tnd $, do.) at Bremen. MacLeod observed 2 moths, 3 short-tongued Hymenoptera, 

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

 x 291). 



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

 Spring Fls.'). 



A. Coleoptera. 1. Lathrimaeum atrocephalum Gyll. ; 2. Tachyporus chryso- 

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

 C. Hemiptera. 4. One sp. 



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

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

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

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

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

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

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

 :88 3 , p. 74). 



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

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

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

 :olour of the hermaphrodite blossoms is almost entirely absent. Female flowers 

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

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

 unctionless. 



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

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

 he drops of nectar which are distinctly visible. 



Burkill observed the following on the Yorkshire coast. 



A. Araneida. 1. 1 sp., lying in wait. B. Collembola. 2. Lepidocyrtus sp. 

 ^. Diptera. (a) Muscidae : 3. Lonchoptera sp. ; 4. Sepsis nigripes Mg. (b) Mycelo- 

 oh'lidae: 5. Exechia sp. ; 6. Sciara sp. (c) Syrphidae: 7. Melanostoma quadri- 

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

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



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

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