86 THE RCOTTISH NATURALIST 



A second outstanding feature was the extraordinary 

 abundance of the larva of Nyssia zonaria, Schiff., on the 

 sandhills lying on the western coast near Daliburgh. This 

 occurrence in myriads was notified by me in the 1910 volume 

 of this journal (pp. 215-217), and it is perhaps sufficient in 

 this place to emphasise the fact that it was almost impossible 

 to sit down to rest without crushing an unpleasantly large 

 number of these fine caterpillars. 



Lastly, while investigating a corrie on the eastern coast 

 of the island, viz. that bearing the name of Bealach an 

 Easain, on the 25th June, I was astonished to find hundreds, 

 perhaps thousands, of pupae of the Currant Moth, Abraxas 

 grossiUariata^ L., lying in the crevices of the rocks. In 

 Barrett's Lepidoptera of the British Islafids, vol, vii., 

 p. 262, this peculiarity of habitat in the Hebrides is thus 

 alluded to : "I am further informed by Mr A, F. Griffiths 

 that in the Hebrides the larvae of this species feed, in 

 multitudes, upon heather {Callima vitlgaris), and that the 

 moths, of ordinary colour and markings, may be seen sitting, 

 side by side, in hundreds on the rocks close above." I 

 collected a number of the pupa;, from which the moths 

 emerged after my return to Edinburgh. There is nothing 

 peculiar in their colour and markings, but their size is 

 somewhat below the average, measuring in expanse of wing 

 only from 32 to 35 millimetres (one inch and a quarter to 

 one inch and three-eighths). 



In order to avoid a repetition of names (with Gaelic 

 spelling !) I append a list of localities investigated, with dates, 

 and in the list of species shall refer to these merely by 

 their numbers : 



1. Slopes of Beinn Ruigh Choinnich, from 100-700 feet 



June 14th. 



2. Roadside, Lochboisdale to Daliburgh 15th. 



3. Sandhills on coast, W. of Daliburgh 15th. 



4. Roadside, Lochboisdale to Daliburgh ; also Loch nan 



Geadh and Loch Chilleirivagh, 2 miles from Lochboisdale 

 Pier (on roadside) i6th. 



5. Slopes of Triuirebheinn, 100-1168 feet 17th. 



6. Sandhills on coast, W. of Daliburgh i8th.
