Collecting at Luss, Loch Lomond, September, 1891. — When 

 an Entomologist visits a new district, it is with feelings of eagerness 

 and inquisitiveness to know what particular insects are to be obtained 

 in the locality. He may be fortunate enough in obtaining many rare 

 and local species which he had not harboured in his anticipations ; he 

 may also be doomed to disappointment ; but what I have to express 

 in the matter is, that I did not feel at all elated at my success last 

 September, when I visited Luss for the first time. The lateness of 

 the season, and the showery and boisterous weather, may account for 

 the lack in number of the insects.
