NOTES ON THE FLORA OF EAST SUTHERLANDSHIRE 37 



In summary we may remark that spring and summer are rather 

 alike as to the decidedly desirable insects ; autumn and summer as 

 to the others. The average of the lower types is higher in autumn 

 than in spring, but the arcrage of the higher types is lower in autumn 

 than in spring ; at the same time, the autumn increases the number 

 where the type is lower, and decreases them where the type has 

 heightened. Summer holds the highest types in each group, but 

 rarely in anything beyond small numbers : Macroglossa, Bombus 

 hortorum, L., Andrena, Odynerus, Rhingia campestris, Mg., Empis 

 tessellata, Mesembrina ineridiana, L., and Siphona geniculata, Drymia 

 liamata and Hyetodesia incana. 



The following table gives the percentages of the whole antho- 

 philous fauna seen in the different seasons :

NOTES ON THE FLORA OF EAST 

 SUTHERLANDSHIRE. 



By G. CLARIDGE DRUCE, M.A., F.L.S. 



IN August 1902 I spent a couple of days at Golspie, and 

 explored the sand dunes, shingle, and pretty glen, as well 

 as the fir woods, the home of Moneses, which are situated on 

 low sandy ground, doubtless at one time covered by the sea. 



Thalictrum dunense, Dum., was rather frequent but very dwarfed 

 on the links. 



Ranunculus bulbosus, Z., occurred as a very branching plant on 

 the links.
