3622 Insects. 



approaches closer, entomologically, to Wales, as I have elsewhere, and 

 at considerable length, taken some pains to prove, (Zool. 898, 1753). 

 Judging indeed from the general character of the insects themselves, 

 and from their paucity, my own observation would tend to connect 

 Devon and Cornwall more immediately with the South of Ireland, 

 where the conditions of insect life are in every respect similar ; re- 

 ceding in every case almost equally from the Welch type, while, inter 

 se, there appears to be, as far as I am able to judge, but little difference. 

 And, in conclusion to this short notice, referring principally to the 

 Coleoptera of Devonshire and Cornwall, I may just add, that return- 

 ing through Somersetshire, I took the opportunity of investigating the 

 sandy coast about Weston-super-Mare; where little however occurred 

 to me beyond the ordinary insects usually abundant in brackish spots, 

 such as Dyschirius salinus, Notaphus ustulatus, Lopha Doris and pu- 

 silla, Ochthebius marinus, Achenium depressum, Atomaria terminata, 

 Corticaria fuscula, &c, which are familiar to every one who has search- 

 ed similar subsaline districts. Passing on from thence into Mon- 

 mouthshire, I located myself at Chepstow, to explore the region of the 

 Wye. At its junction with the Severn, its Fauna is almost identical 

 with that about Weston, but more especially with what I have ob- 

 served in northern Lincolnshire, on the edges of the Humber ; the 

 self-same species occurring in each locality, with the exception how- 

 ever of Pogonus littoralis, which is found abundantly on the Wye, but 

 which I have not remarked on the Humber banks. In other respects 

 they entirely coincide; Dyschirius salinus, Peryphus lunatus and con- 

 cinnus, Philocthus aeneus, Lopha Doris and pusilla, Heterocerus fe- 

 moralis, and another minute species, probably the sericans of Keisen- 

 wetter ; to say nothing of the elegant little Hemipterous insect, the 

 Salda pulchella of Curtis, occurring in equal abundance in both dis- 

 tricts. But, following the Wye from its junction with the Severn up 

 to Chepstow itself, we find that the character of the insects entirely 

 changes. Luxuriant woods here begin to clothe the lofty banks of 

 the river, forming a large item in that lovely scenery for which the 

 Wye has ever been so famous. In the portion of the woods between 

 the ruins of the castle and the estate of Piercefield, I alighted upon a 

 host of rarities, including, amongst many species which I need not re- 

 cord, a fine series of Orsodacna chlorotica (principally on the flowers 

 of the common meadow-sweet), in all its varieties, Cistela castanea, 

 Magdalis Cerasi and aterrima, Ochina Hedera? (abundantly in the old 

 ivy which clusters upon the rocks), Chrysomela laminata, Oomorphus 

 concolor, and several species of Staphylinidae. And further up the
