246 Entomological Notes on a Journey through Part 



The afternoon of Friday proved fine ; and I resolved on 

 ascending Snowdon the next day. Accordingly, about 7 o'clock 

 on the ensuing morning, accompanied by a guide, I started, 

 the summit of the mountain being ten miles distant. There 

 was every appearance of a fine day, in which I was not 

 disappointed. The pretty moth Aplocera caesiata, much 

 faded, frequently flew out from the stone walls which lined 

 the road. I availed myself of such opportunities as pre- 

 sented themselves for collecting ; my guide, who knew the 

 locality, directed me to the spot for Carabus glabratus, of 

 which we took many. Higher up the ascent, and indeed al- 

 most to the summit, I took both the red and black-legged 

 varieties of Helobia Gyllenhal?'/ in considerable abundance, 

 and some few specimens of Helobia Marshalla/wr. Patrobus 

 rufipes was very common ; and I took one within 6 ft. of the 

 extreme summit, i. e. 3500 ft. above the level of the sea. I 

 should not have named this common beetle, but from its hav- 

 ing been described as a littoral [coast] insect. I reached the 

 highest peak of the mountain, called Ywyddra, about mid- 

 day : and, while admiring the magnificent prospect which an 

 almost unclouded sky afforded, I saw a P6nti« flit by ; and, 

 shortly after, a small Geometra, either Harpalyc^ fulvata or 

 Acidali«? bilineata. I was rather too late for Chrysomela 

 cerealis, which, together with Leistus montanus, were taken 

 on this and neighbouring mountains in June. I descended on 

 the Llanberris side of Snowdon, and proceeded, by way of 

 Caernarvon and Bangor, to Holyhead, and on the ensuing 

 morning reached Dublin. 



On the 25th and 27th of July I availed myself of a little 

 leisure, to collect on the sand hills at Port Marnoch, about 

 eight miles from Dublin. Several of the Papilionidae were in 

 abundance; among others, Argynnis Aglaia and Hipparchia 

 Semek were very fine. I scarcely observed a single coleop- 

 terous insect, except Serica brunnea ; both days were dull, 

 with occasional gleams of sunshine. On the flowers of the 

 ragwort (iSenecio Jacobae^«), and close to the sea, I took 

 several species of the genus A'grotis, in excellent condition, 

 viz. valligera, tritici L. and hortorum Steph,^ which, I think, 

 is a variety of the former, and lineolata Haw. Among a 

 dwarf »Salix,a small but beautiful Tortrix, Lozotae^nia cruciana, 

 was in the utmost profusion, but very difficult to secure. 

 Many species of Bombus were also alighting on the various 

 flowers. Pompilus nigra, and Colletes succincta were also 

 frequent. These sand hills are fertile in good insects; and 

 Mr. Tardy, the most active of the few entomologists in Dub- 

 lin, informs me that the larvae of Actebia prae^cox, Miana- 

 literosa, and Phragmatobia fuliginosa are abundant. On the
