Exhibitions. 

 Mv. Janson exhibited, on the part of Mr. H. Squire, a box of Coleoptera, collected 

 by him during a visit which he had just made to the Shetland Isles, and vemarlied, that 

 considering the period of the year at which this trip was undertaken, his short stay of 

 a week only, and the limited district which he had investigated (for the unpropitious 

 state of the weather had precluded him from extending his excursions beyond three 

 miles from Lerwick) the series now before the Meeting must be looked upon as highly 

 satisfactory. The number of species amounts to one hundred and twenty-live, and, 

 although the major portion of them are forms familiar to every London entomologist, 

 still there are among them several to which he would direct the attention of the 

 Meetii5g. 



The first of these is apparently a species altogether new to the British list, the 

 veritable Nebria (Carabus) nivalis of Paykull, which Drs. Kraatz and Schaum have 

 recently shown is not identical with N. Gyllenhalli, Schomh., as had been generally 

 supposed. The specimens now under consideration differ from N. Gyllenhalli (the 

 ci-devant nivalis of British collections) in having a smaller thorax, which is more 

 narrowed posteriorly; the striae on the elytra are much shallowed, and the impressed 

 points or punctures much more evident; and, moreover, the femora are black, the tibiae 

 and tarsi alone being red. 



The second is a Patrobus which does not entirely correspond with the P. excavatus, 

 Payk., Dawson, differing in having the thorax shorter and more rounded at the sides 

 and its sculpture coarser; it appears to agree with an insect taken by Mr. Murray in 

 the Clova Mountains, by the Rev. Hamlet Clark in North Wales, and by Dr. Power 

 in Lancashire. Mr. Squire, who has compared it with continental specimens of 

 P. lapponicus, Chand., in the national collection, refers it to that species. 



The third is a species of Hydroporus manifestly differing from any at present in our 

 list, and which the Rev. Hamlet Clark considers will, in all probability, prove to be 

 the H. Lapponum of Gyllenhal, 



Fourthly, Hydroporus halensis. 



Fifthly, Oiiorhynchus maurus. 



And lastly, an Omalium, which is scarcely referrible to any of the recorded species, 



Mr. Stevens exhibited a specimen of Pieris Daplidice, taken by Mr. Spencer, near 

 the South Foreland lighthouse, on the Oth of August last. 



The Rev. Hamlet Clark exhibited a box of Coleoptera, recently taken by Dr. Power 

 in Lancashire, containing an extensive series of Bembidia, and numerous rare 

 Staphylinidae, &c. ; also a singular monstrosity of Bembidium concinnum, having 2^ 

 tarsi on one of the fore legs ; a specimen of Euryporus picipes, taken at Preston Marsh 

 by Mr. Graham ; and Hydroporus ferrugineus, also from Lancashire, being a new- 

 locality for that rare species. He also exhibited a specimen of Opilus nnivittatus, 

 Rossi, a species hitherto considered peculiar to Italy, which had been sent alive in a 

 pill-box to Mr. Baly, by a lady residing at Malvern, 



Mr. Stevens exhibited a small box of insects, sent by Mr. Shield from Monte 

 Video, containing, amongst other minute Coleoptera and Lepidoptera, a singular 

 species allied to Claviger, found in ants' nests, and a Lithocolletis closely allied to 

 L. lautella of Europe. 



Mr. Douglas exhibited an apparently new s|)ecies of Colcophora, found amongst 

 Atriplex, at Scaford, in Sussex ; also a small Heterocerus, and a Bryaxis, of which he
