90 ANNALS OF SCOTTISH NATURAL HISTORY 



proposed list. In these circumstances it may be well to 

 record now the more interesting of my recent captures ; 

 perhaps help from unexpected quarters may thereby be 

 evoked. In the case of the Micros (to which unfortunately 

 few collectors pay any heed) I have given a pretty full 

 record, but as regards the Macros, only the less common 

 (that is, in my experience) are mentioned. 



A number of the species included in the following 

 memoranda have not, so far as I know, been previously 

 recorded for the district, a few of them apparently not for 

 any part of Scotland, but I have not yet been able to look 

 so thoroughly into the scattered literature as to feel justified 

 in making positive statements in this respect. 



Whatever difficulties may attend the collecting of Micro- 

 Lepidoptera, they are as nothing compared to the difficulty of 

 naming them ; and I shall not readily forget the pleasure I 

 experienced when Mr. Charles G. Barrett, F.E.S., consented 

 to name specimens for me. I scarcely like to think of the 

 extent to which I have already taken advantage of his able 

 and ready assistance ; but when I state that specimens of all 

 the Micros and also of most of the smaller Geometers here 

 recorded have passed through his hands, some idea of my 

 indebtedness to him may be formed. He has earned my 

 warmest gratitude, and, I need scarcely say, he has it. 



In the matter of arrangement and nomenclature I have 

 followed South's list, 1 that being, I understand, the one at 

 present favoured by the Editors of the " Annals." Where 

 the specific name adopted in that list displaces a familiar 

 " Doubleday's list " one, the latter is given within brackets. 

 The explicit adoption of the nomenclature of a particular list 

 seems, in the case of papers like this, to do away with the 

 necessity for writing the " authority " after each name ; at 

 any rate, I gladly avail myself of this view as an excuse for 

 leaving them out on the present occasion. 



Although scarcely falling within the title of my paper, I 

 have availed myself of the opportunity to record a few in- 

 teresting captures made, during April and May 1896, in the 

 neighbourhood of Aberfoyle in the upper section of the 



1 "The Entomologist" synonymic list of British Lepidoptera, by Richard 

 South (London, 1884).
