56 ANNALS OF SCOTTISH NATURAL HISTORY 



Mr. Barrett, I see, writes as if this moth were not known to occur 

 in any county of the mainland of Scotland but Perth. I can 

 myself vouch for its occurrence in Inverness-shire, having found the 

 larva near Dalwhinnie in 1892 ; and there is a record of its 

 occurrence near Braemar in Aberdeenshire in 1873 m tne "Scottish 

 Naturalist," vol. ii. p. 162. In Buchanan-White's " Lepidoptera of 

 Scotland" it is noted as occurring in both "Tay" and "Dee." 

 My chief object, however, in sending this note is to give what I do 

 not find mentioned in any account of the moth I have seen, namely, 

 the name of the " moss " in which the lame and pupae are found. 

 The plant is the Rhacomitrhtm lanuginosiim of Bridel ( = Grimmia 

 hypnoides, Lindb.), a true moss, which grows in great profusion on 

 the higher ridges and slopes of the Grampians and Cairngorms. 

 Its broad, hoary cushions are favourite nesting sites with that most 

 interesting bird the Dotterel. WILLIAM EVANS, Edinburgh. 



Limnophilus borealis, Zett., and L. nigrieeps, Zetf., from Glen 

 Tilt. I am indebted to Mr. William Evans for a fine specimen of 

 Limnophilus borealis taken by him near Fenderbridge, Glen Tilt 

 (East Perth). This species is exclusively northern in Scotland, and it 

 seems to be decidedly local. Mr. M'Lachlan has kindly given me 

 the following localities : Strathglass (Buchanan-White, 1869) and 

 Strathnaver (Trail, i2th August 1873). Mr. King has also taken it 

 somewhere between the Tummel and Glen Lyon. Abroad, its 

 distribution is mainly boreal, and it is common in Northern Scandi- 

 navia. This year (1898) it was taken for the first time in the Valle'e 

 de Joux, Switzerland. From the same locality as L. borealis, Mr. 

 Evans has given me an example of L. nigriceps, Zett, a species which 

 is also somewhat local both in this country and on the Continent.

On the occurrence of Boreophausia inermis (Kroyer) and 

 Thysanoessa longieaudata (Kroyer) in the Firth of Forth. Some 

 time ago I examined several unnamed Crustaceans belonging to the 

 Euphausiidae that had been collected in the Firth of Forth at various 

 times between 1891 and 1894. They were found to comprise 

 representatives of four different species, the names of which are as 

 follows : Boreophausia raschi (M. Sars), Thysanoessa negleeta (Kroyer), 

 Boreophausia inermis (Kroyer), and Thysanoessa longieaudata 

 (Kroyer). Though the first and second have already been recorded, 

 the other two appear to be additions to the Crustacean fauna of the 

 Forth. The specimens of Boreophausia inermis were collected in 

 1892 and 1894, and those of Thysanoessa longieaudata in 1891. 

 Boreophausia inermis differs from B. raschi in having the rostrum 

 narrow instead of triangular, and in having a spine over the base of 

 the telson ; B. raschi having no such spine. Thysanoessa longieaudata 

 may also be distinguished from its near ally T. neglecta by not
