of plum and apple trees. In the first leaflet (No 308) the damage 

 caused by several species of Plum Aphides {Aphis priini, Hyalop- 

 terus pruni, and Phorodon hiiimili) is described, the life-history of 

 the insects is summarised, and methods, such as lime, sulphur, and 

 nicotine washes, are suggested for keeping the pests under control. 

 The second leaflet (No. 319) describes Apple Capsids {Plesiocorts 

 rugicollis) as among the most dangerous pests of the apple. In 

 natural conditions this species is widely distributed throughout the 

 country on willows and sallows, but its invasion of orchards is still 

 limited in extent. The piercing of the outer layers of twigs, leaves, 

 and fruit by the bugs in their efforts to reach the plant sap within, 

 causes local damages which may checlc the growth of the leaves, 

 kill the young twigs, and reduce as well as render unfit for market 

 the fruit crop. A nicotine spray applied a week before the opening 

 of the blossom is the surest remedy. 



Lepidoptera of Rannoch. Rev. J. W. Metcalfe gives an 

 account of the Lepidoptera of Rannoch as he found them during a 

 month's sojourn in June and July 19 18, The captures are discussed 

 according to their local habitats heather-moor, meadow, black 

 wood, foothills, birch wood, or mountain-side so that the paper is a 

 useful guide to the possibilities of the Rannoch area. {Entomologist^ 

 December 1918, p. 262.) 



In the Entomologist for April and May 1919 (pp. S3-88 and 106- 

 112) J. J. Lister, F.R.S., F.E.S., writes "On some North-Country 

 Species and Forms of Lepidoptera." The Scottish locality selected 

 for investigation was Loch Rannoch and its immediate neighbour- 

 hood. The visit extended from 4th July to 12th July, and the 

 article gives details of the capture of Cxnonyviplia tiphon var. 

 laidion, Bork., in two or three localities around the loch at an 

 elevation of about 1700 feet above sea-level. Erebia epiphron, 

 A?-icia mcdon var. artaxerxes, Polyommatus icams (interesting forms 

 of the female), Argyn?iis aglaia, and Brenthis sekne were also taken, 

 and a specimen of Euvanessa aiitiopa reported to have been seen at 

 Kinloch Rannoch on 6th July. Several species of Geometrid 

 Moths are recorded, but nothing of outstanding importance is 

 included. 



Nyssia lapponaria in Inverness-shire. In the Entomolodst 



o 



for June 1919 (p. 141) R. A. S. Redmayne, M.B.. records the 

 capture, on 21st April, of four males of this species of moth at 

 Invergarry. According to the author of this note (and also so far 

 as our own information goes) the species has hitherto been recorded 

 only from the county of Perthshire.
