point there is a small group of Scots firs, amongst which the 
golden-crested wren was observed. 
On 4th June, 1904, an excursion to Luss took place for the 
purpose of visiting the islands, on which occasion the party 
divided, thus being enabled to take in the three islands of 
Inchmoan, Inchconnachan, and Inchtavannach. On the island 
of Inchconnachan nests of the redstart and _ redbreasted 
merganser were found, and the capercaillie was also observed. 
The wood-wren and willow-wren were also seen on this island, 
the latter considerably outnumbering the former. At _ this 
excursion a full list of the Diptera observed on all three islands 
was compiled by members of the entomological section, and is 
here given as a contribution to the insect-fauna of the Loch 
Lomond islands.
