228 THE SCOTTISH NATURALIST 



May, who, ably seconded by Mrs Wilson and Mrs Baigrie, 

 have rendered special service ; J. Mowat, Isle of May ; 

 Miss L. J. Rintoul and Miss Evelyn V. Baxter, Isle of 

 May ; J. Moore, St Abb's Head ; D. Stewart, D. Budge, 

 and A. M'Millan, Barnsness ; J. M. Campbell, Bass Rock ; J. 

 Johnstone, D. M'Donald, and G. Miller, Fidra ; W. Begg, 

 Inchkeith ; T. Wilson and H. G. Kelcey, North Carr Light- 

 ship ; C. M'Connick, Bell Rock ; D. A. Mowat, Killantringan ; 

 R. Clyne, Butt of Lewis ; W. Eagle Clarke, Auskerry and 

 Fair Isle ; C. M'Eachern, North Unst. Besides those caught 

 at the lighthouse on the Isle of May, many specimens have 

 been taken at the engine-house and adjoining buildings ; 

 these, however, do not strictly come within the scope of this 

 report, and will be dealt with in a paper on the fauna of the 

 island in general. In respect of these latter specimens, 

 acknowledgments are due to J. M'Kenzie, H. M'Innes, 

 W. Mouat, M. Cunningham, and last but not least my 

 friends, Mr and Mrs Ross, whose hospitality I have so often 

 enjoyed. 



For help in the identification of a number of the Trichop- 

 tera and Diptera respectively, I have to thank Mr Morton 

 and Mr Grimshaw.

Lepidoptera. 



Vanessa urticce, L. (Tortoiseshell). 



Isle of May : a female (?) of this butterfly was taken at the 

 lantern on the night of 27th May 191 2. Other examples have 

 occurred in this lighthouse, and also in that on the Bass Rock and 

 Fidra Island, but not, I understand, at the lantern. Early in April 

 1910 a Red Admiral (V. atalantd) was caught in Mr Ross's house, 

 Isle of May ; that, however, is some distance from the lighthouse. 



Lycczna z'cart/s, Rott. (a/exis, Hb.). 



St Abb's Head : a female of the Common Blue Butterfly was 

 taken at the lantern on the night of 1st July 19 14 by Mr J. Moore, 

 lightkeeper, from whom I got it next day. Its coming to the light 

 is a fact of considerable interest.
