1754 Insects. 



the species I then collected might be coincident with the Welch ones. 

 Still, judging from their extraordinary want of similarity to those 

 which I had been accustomed to observe on the north coast of Devon- 

 shire and Cornwall, and the occurrence of a few remarkable species 

 which I knew to be common throughout the south of Wales ; I was 

 inclined to believe, that, in spite of the immense difference between 

 the distances of the two shores, (the one being about thirty miles in a 

 direct line, the other only fourteen), they partook more of the charac- 

 ter of the Welch Coleoptera than of those, as we should have naturally 

 supposed, of the nearest coast; in which conjecture I have since 

 found that I was not mistaken. The following species, which I took 

 at Lundy, occurred profusely at Tenby and in its immediate vicinity : 

 Dromius foveolus, Haliplus lineato-collis, Hydroporus nigrita and 

 jugularis, Parnus prolefericornis, Laccobius minutus and globosus, 

 Cercyon stercorarium, Aphodius ater, Rhinonchus pericarpius, Sitona 

 puncticollis, Thyamis tabida, Cteniopus sulphureus, Aleochara fus- 

 cipes and nitida, Philonthus lituratus, Xantholinus glabratus and 

 linearis. At Carmathen also many species were particularly abundant, 

 which were in equal profusion at Lundy. J might mention, amongst 

 others, as characteristic, Argutor erythropus, Trechus minutus, Har- 

 palus aeneus, Helephorus griseus, Limnebius truncatellus, Otiorhyn- 

 chus ligneus, Apion violaceum, Raphirus semiobscurus, Oxytelus de- 

 pressus, Staphylinus aeneocephalus, &c. There are a few of these 

 which T could lay more particular stress upon, because they are re- 

 markably local, and seem to point especially to some peculiar (though 

 in the present instance, obscure) similarity in the places which pro- 

 duce them. 



Thus, the beautiful Cteniopus sulphureus, I have in vain searched 

 for on the north coasts of Devonshire and Cornwall, though abound- 

 ing with the identical kind of flowers in which they occur so profusely 

 in Lundy Island and Wales. At Tenby they may be found on the 

 umbelliferous plants which are scattered sparingly over the sand-hills 

 facing the sea. In Lundy they were in the greatest profusion, and, 

 though confined in so small an island, it was really curious even there 

 to remark their excessive partiality to a single spot. Confining them- 

 selves to a most minute area in the south-eastern part of the island, 

 they were contented to remain there and were never observed to 

 roam. In the sunshine, indeed, they might be seen occasionally on 

 the wing, but they were merely passing from flower to flower and wan- 

 dered not from their prescribed sphere. It was rare, however, to find 

 them on the wing at all, for they were usually buried deep in the
