22 THE SCOTTISH NATURALIST 



Trec/ius minntus, F., race obtusiis, Er. — ^Tvvo. 



Hydropoms eryfhrocephahis, L. — Twelve. 



Hydroponis pubescens, Gyll. — One. 



Agabus bipustulatus, L. — Thirty-one. 



Gyrinus natator, Scop. — Seventeen ; from peat-pools on moor. 



Hydrobiiis fuscipes, L., race picicri/s, Sharp. — Nineteen. I am 

 not aware of any record of this species from either Orkney or 

 Shetland. 



Honialota ci/rrax, Kr. — Two. The same remark applies to this. 



Quedius mesomelmus. Marsh. — Two. It is possible that this is 

 the same as Q.fulgidus of Blackburn and Lilley's Shetland list. 



Ocypns okiis, Mlill. — Four examples. 



Philonthus decoriis, Grav. — One. 



Oxvfeliis laqueaius, Marsh. — One, var. with dark elytra. Not 

 recorded from either Orkney or Shetland so far as I have seen, and 

 the same remark applies to the next two species. 



Choleva morio, F. — Four, all males. 



Chokva chrysoincloides, Panz. — Six {2 $ , 4 ? )• 



Aphodius contaDiinatus., Herbst. — Thirteen. 



Otiorrhynchits maurus, Gyll. — One specimen. This is a 

 mountain insect on the mainland of Scotland. 



I may add that on 2nd September 191 3, Mr Clarke saw 

 immense numbers of Chrysomela fastuosa, L., specimens of 

 which he has shown to me, between Stromness and Stennis. 

 They were scattered along the roadsides for miles. The 

 species, however, had already been recorded from Orkney. 



The Generic Names of the S"wallows and Divers. — 



British ornithological opinion has been divided of late regarding the 

 correct generic names for the Swallows and Divers— should it be 

 Hirundo or Chelidon for the former, and for the latter Colyvibiis or 

 Fodiceps? In The Auk for October (p. 525) is an expression of 

 American opinion on the subject, wherein it is declared that the 

 type of Hirtmdo is rustica and that of Colymbus is arcticus, and 

 the nomenclature of the A.O.U. List of American Birds is to be 

 altered accordingly. This finding confirms the opinion of the 

 Authors of the B.O.U. List of B)-itish Birds on these vexed 

 questions in nomenclature.
