ENTOMOLOGICAL EXCURSION. 53 ' 



ascended the mountain at the back of the inn. Under stones 

 we found beautiful green varieties of Notiophilus quadripunc- 

 tatus, Omaseus orinonmm, nigrita, rotundicoUis (Steph. MS.), 

 Patrobns rvfipes, and a few other Carabidce. We also ob- 

 served the beautiful little plant Pinguicula vulgaris, growing in 

 great abundance on the wet and boggy parts of the mountain. 

 Having reached the summit, we saw the whole mass of the 

 Snowdon mountains in unclouded majesty before us. The air 

 was slightly hazy ; but not sufficiently so to interfere in the least 

 with the magnificence of the outline. As we descended, we 

 observed a belt of clouds passing between us and Snowdon, 

 a thousand, or perhaps fifteen hundred feet below the highest 

 peak. On our return to the inn we found a botanical friend^ 

 of ours, who, with a party of his relations, had arrived during 

 our absence ; and with whom we immediately fixed on ascending 

 Snowdon the following morning. In the evening, we took 

 several Phryganece flying about the river; and among them 

 the beautiful Philopotomus scopulorum, and a large Perla 

 apparently marginata. 



9th. The party who had arrived last evening kindly gave 

 us seats in their carriage from Capel Curig to the pass of 

 Llanberris. We three naturalists then commenced the ascent on 

 foot, accompanied by a guide named David Jones, an incipient 

 insect-collector of great promise. In the first quarter of an 

 hour, we had taken Carabus glabratus and arvensis, Steropus 

 JEthiops, Helobia Marshallana and Gyllenhalii, Elater 

 cupreus and jiectiniconiis (the former is in great abundance, 

 both sexes of each), Telephorus JEthiops, a Byrrhus appa- 

 rently undescribed,"^ and several other insects we had neither 

 of us before taken. 



We now found, by the masses of clouds which rolled in 

 grand and billowy succession down the mountain-side, that 

 we might shortly expect rain : and scarcely had we arrived at 

 this conclusion, when rain, hail, and snow, or a compound of 

 the three, began to fall around us in torrents, and very speedily
