262 THE SCOTTISH NATURALIST 



the sea braes west of Elie, Fife, on ioth August, but my son saw 

 one on the sandhills behind Gullane, on 29th July, and others, I 

 understand, were seen about the same date on that part of the 

 Haddingtonshire coast. — -William Evans, Edinburgh. 



Some Lepidoptera and other Insects from St Kilda. — 



In a miscellaneous collection of terrestrial invertebrates, made by 

 Mr Eagle Clarke at St Kilda in the autumns of 1910 and 191 1, I 

 find the following Lepidoptera represented, each by one example : — 



Agrotis lucernea, L., September 191 1. 

 Triphcena pronabct) L., „ 19 10. 



Apamea genii n a, Hub. , , , 1 9 1 1 . 



Hydrcecia micacea, Esp., ,, 19 10. 



Coremia didymata, L., ,, 191 1. 



None of these moths would appear to have been previously recorded 

 from St Kilda. 



There is also a specimen (male), taken in September 19 10, of 

 the Trichopteron Stenophylax permistus, M'Lach. {concentricus, M'L. 

 nee Zett), a Caddis-fly not previously on the St Kilda list. Mr K. 

 J. Morton, to whom I have shown this specimen, has confirmed 

 my identification. 



The collection contains a number of examples of the small 

 brown Ant, My r mica rubra, race ruginodis, and of the common 

 Earwig, Forficula auricularia, both of which have, however, been 

 already recorded from the island. For previous lists of insects from 

 St Kilda, the Ann. Scot. Nat. Hist, for 1906- 1908 should be 

 consulted. — William Evans, Edinburgh. 



Docophorus melanocephalus, N., a straggler on the Knot 

 in Shetland. — During the last half of August (191 2), a great flock 

 of Knots (Tringa canutus) made their appearance near Sullom, 

 N. Mavine, and a number passed through the writer's hands for 

 examination. From these birds over 500 Mallophaga, representing 

 4 genera and 7 species, were taken. One of them, D. melanocephalus 

 (1 $ and 2 ? $ ), is interesting from the fact that its usual hosts are 

 members of the genus Sterna (Terns). In Shetland the Docophorus 

 occurs sparingly on S. fluviatilis and S. macrura, but it seems 

 unlikely that the transference from one host to the other was effected 

 here. More probably this took place in the Knots' summer quarters, 

 where they may have been breeding in company with Terns. 

 The original host was probably S, macrura. — James Waterston, 

 Ollaberry, Shetland.
