NOTES ON SOME RARE TITRIPS FROM SCOTLAND 



37 



yellow, with mid femora much thicker than the fore femora. 

 Wings yellow tinged, with veins 3 and 4 distinctly converging. 

 Size 5 mm. 



I do not know ecalceata, Zett, which also has quite yellow- 

 antenna; and tarsi, but major appears to be abundantly distinct, by 

 reason of its larger size and different wins-venation. 





NOTES ON SOME RARE THRIPS {THYSAN- 

 OPTERA) FROM SCOTLAND. 



By Richard S. BAGNALL F.L.S., F.E.S., Hope Department of 

 Zoology, University Museum, Oxford. 



SINCE the publication of Haliday's Epitome in 1832 no 

 attention whatever has been given by British entomologists 

 to the study of these small but important insects until very 

 recently. Of the species diagnosed by Haliday we recognise 

 thirty-seven, but, since I first took up the group a few years 

 ago numerous discoveries have been made, and the British 

 list now stands at eighty-two species falling into thirty-four 

 genera. I possess a good deal of material from the Clyde 

 and Forth areas of Scotland, and smaller collections from 

 the neighbourhood of Dundee, of Aberdeen, and of Nethy 

 Bridge. 



I trust that this material will be largely increased so that 

 an account of the Scottish species may be attempted in the 

 near future. Thrips are easily collected and preserved, and I 

 should much like to correspond with collectors from all parts 

 of the British Isles. 



The following species, are, in the meantime, worthy of 

 note : 



Sub-order Xerebrantia. Family Thripid.e. 



Amblvthrips erica, Bagnall. 1 -Though the genus and species 

 was diagnosed from material collected at Ravenscar, in Yorkshire, in 

 the autumn of 1910, I have in my possession an example from 

 Colintraive, in the Kyles of Bute, taken in July 1907.
