find it at all common. H. liiimuli appeared about the latter end 

 of June, and occurred in every place that I worked at all ; it was 

 the only moth that I took on Little Bernera Island. 



Camptogramma hilineata apparently emerged two or three 

 days before I left, and I did not find it in any numbers until the 

 last few hours of my stay in the Lewis. It appeared to be local, 

 occurring on rocks and in the growth surrounding them, but 

 only in certain places ; one might search for an hour in the 

 heather around the base of rocks without seeing a single speci- 

 men, then suddenly one would find eight or ten together. 

 Possibly it is more generally distributed later in the season. 



Sugaring was a failure ; I do not know if it was from the 

 absence of sugar-loving moths, bad nights, or bad sugar. Who- 

 ever wishes to sugar in that neighbourhood had better bring his 

 own rum. I thought I could buy any form of alcohol easily 

 there, but rum does not appear to be' a very coveted liquor, as it 

 is not retailed out, and I had to buy a bottle. This bottle was 

 sealed and marked "rum," and contained some sort of spirit, but 

 what it really was I do not know, and the moths could not make 

 it out either, I suppose, as they didn't turn up. 



I saw very few species of butterflies. Lycana (Polyommatus) 

 icarus occurred sparingly, the males being much the more 

 common. 



Coeno7iympha davus was abundant on the moors, and gave 

 me a rare chase over the boggy ground. Epinephele ianira was 

 fairly common. The only Vanessid I saw was one Vanessa 

 atalanta. 



Besides the insects above mentioned I took a few dragonflies, 

 which I gave to Mr. Lucas, who, I believe, finds them of some 

 interest. 



Any collector from the South of England coming for the first 

 time to this northern region must, like myself, have noticed 

 many things that were quite new to him. The short night 

 threw me out entirely with regard to time. I would see the sun 

 in the afternoon fairly high in the heavens, and think it must be 

 about 6 o'clock, and then find to my astonishment that it was 

 8 p.m. Evening commenced at about 9.30, and then velleda 

 would fly for an hour or so, after which time it would be dark 

 enough for the small Geometers to show themselves, and I could 

 net these and other moths until 11 p.m. I usually collected 

 until midnight, and on returning home could see the time by my 

 watch, as the whole northern sky had a yellow glow which lit up 

 the surrounding country and made all objects distinctly visible. 

 This twilight was the nearest approach to night, for in an hour 

 the light would shine more strongly in the east, a lark commence 

 to sing, and the morning break. The chief annoyances to 

 collecting were clegs during the day and midges in the evening. 

 Of the two I prefer clegs, as they can easily be seen and only
