 mology in the University of Cambridge. 



In Jul)- of last year a party of zoologists from Cambridge 

 spent about three weeks in the Outer Hebrides. Mr F. 

 Balfour- Browne, the originator of the expedition, has pub- 

 lished the results of his study of the Aquatic Coleoptera 

 in the current volume of the Scottish Naturalist (January, 

 March, April, and May 191 5). He describes the localities 

 visited {op. cit., p. 14 sgq.), which were the undulating, peat- 

 covered district round Barvas in the north of Lewis, and 

 the more mountainous neighbourhood of Tarbert, Harris, 

 in the south of the island. The bulk of the insects mentioned 

 here were found in the northern locality. 



In addition to the Aquatic Coleoptera, a number of other 

 beetles were collected by Mr G. B. Hony, but as that gentle- 

 man is serving at the front he has been unable to determine 

 the material. A series of Diptera was obtained by Mr C. G. 

 Lamb, who has sent records of the species to Mr Grimshaw 

 for publication in connection with his paper on Hebridean 

 flies. The remainder of the insect- material consists of 

 Lepidoptera, Hymenoptera, Neuroptera (s.l.), and Siphon- 

 aptera, all of which have been determined, as given belov/, 

 by specialists, to whom my best thanks are due for their 

 kind help. 



Lepidoptera. — These have been determined by ]\Ir P. A. 

 Buxton, who has furnished me with the following list (the material 

 was mostly collected by G. B. Hony) : — Pieris brassiccc, Epinephele 

 j?/?iina {jaiiira), Polxoiuniatits icnrus^ Ncmeophila plafttaginis, 

 Agrotis vestigialis, A. porphyrea {sirigula), Xylophasia monoglypha 

 (black forms, intermediates of several shades, and type forms were 

 all fairly common), Charivas gravii?ns, PInsia gamma, Camffo- 

 gramma hilineafa (the only specimen is rather dark and rather
