Our object in noticing the present number, which in point of exe- cution exceeds even the two preceding, is to call attention to the ad- mirable figure of Puccinia graminis, or mildew. It is far more com- plete than that so often referred to of Bauer. Among the points elucidated in the present number, is the very interesting one that Asterophora is a mere parasite of the second order, its matrix having perfect sporidia. The author does not seem to have access to many well-known journals, or he would not have published as Sporocyhe Desmazierii a plant altogether unlike that figured under that name in the ' Annales des Sciences Naturelles ;' neither would Sphceria Robertsii, Hook., of which an admirable analysis is given, appear as an undescribed species, Sp. Hugelii, PROCEEDINGS OF LEARNED SOCIETIES. ENTOMOLOGICAL SOCIETY. January 4th, 1841.— The Rev. F. W. Hope, F.R.S., President, in the Chair. The President stated, in reference to Mr. Schomburgk's memoir, read at a previous meeting, that migrations of butterflies to a very great extent had been repeatedly observed in South America, in- stances of which had been recorded in Helme's account of Buenos Ayres. Mr. Westwood corrected an error which had occurred in the printing of a memoir relative to the Pediculus Melittce of Kirby, or Entomological Society, 435 the larva of Meloe, in the Transactions of the Society, in which it had been stated that the specimens which he had found at large and dissected were identical with some reared by the Rev. L. Jenyns from the larva of the Meloe, whereas the latter had been reared from the eggs of that insect. This correction was especially required, because in the volume upon insects in the Cabinet Cyclopaedia it had been suggested by Mr. Shuckard that the two insects were not iden- tical. A memoir was read by Mr. Westwood on the nomenclature of the genus Chlorion of Latreille {Ampulex, Jurine). From a review of Latreille's various works it appears, that although at the first he gave the Sphex lobata, Fabr. as the type of the genus, yet its characters were not derived from that insect, but agree with the Sphex com- pressa, Fabr. Fabricius, however, adopted and characterized the genus Chlorion from the former of these two species, but included in it also Sphex compressa. Jurine, however, finding the latter species not to agree generically with the former, proposed the name of Am- pulex for the Sphex compressa, and figured an European species as an example, which however does not precisely agree with S. compressa. Under these circumstances the author considers that the name of Chlorion ought to be applied to the genus typified by Sphex com" pressa, that the Chlorion of Fabricius requires another name, and that the name Ampulex is strictly synonymous with Chlorion, the same species being the true type of both generic names. In allusion to the employment of synonymical names of genera, Mr. Yarrell stated that a calculation had been made by Messrs. Agassiz and De- CandoUe, by which it appeared that no less than 300 generic names of plants and 800 names of zoological genera required changing, having been previously used in other branches, and it was insisted upon by several members that the inconvenience which would neces- sarily result from the change in such a number of names would far overbalance the occasional slight inconveniences at present felt in cases of such " double emploies," as the French term them. It was further suggested by Mr. Waterhouse, that as Latreille had erred in the first instance in giving as the type of Chlorion an insect which did not accord with the generic characters which he had detailed, we ought to adopt the nomenclature of Fabricius, who had given the real characters of the insect which Latreille had mentioned as its typical species. Anniversary meeting, January 25th, 1 841 . — The Rev. F. W. Hope in the Chair. At this Meeting the ordinary business of the annual meeting took place. W. Sells, G. R. Waterhouse, S. Stevens, and W. Bennett, Esqrs., were elected into the Council in the room of E. Charles worth, W. E. Shuckard, J. F. Stephens, and F. Walker, Esqrs., and W. W. Saunders, Esq., F.L.S., was elected President, W. Yarrell, Esq., Treasurer, and J. O. Westwood, Secretary for the ensuing year. In the address delivered by the Rev. F. W. Hope, after favourably commenting upon the character of the Society's Transactions, he 2 F 2 436 Linnaean Society. suggested the propriety of members taking up the old theses of Liir-< nseus and bringing down the subjects therein treated upon to the present state of the science. The injurious effects of insects upon agricultural and horticultural productions ought also to engage the attention of the members. He would also recommend the formation of committees, taking up and annually reporting upon the entomo- logy of the various geographical districts : and he alluded to the great loss the Society and science had sustained by the deaths of Dr. Goodall, Mr. Vigors, arid Major Gyllenhal. It was announced that the caterpillar of one of the Noctuidce which devours the roots of turnips should be again proposed as the subject of the essay for the prize of ten guineas, offered by the Society ii> conjunction with the Saffron Walden Agricultural Society. The Rev. F. W. Hope also announced his intention of giving a^ prize of £10 for the best essay on the insects which attack apple and pear trees, with the best remedy for their destruction. LINNiEAN SOCIETYr March 2, 1841.— Mr. Forster, V.P., in the Chair. Read a " Note on the Preservation of Specimens of Natural History." By Hyde Clarke, Esq., F.L.S. Mr. Clarke suggests the application of Payne's apparatus for the preservation of animal substances for domestic purposes, to the pre-' servation of objects of Natural History. The ap])aratus consists of an iron cylinder, in which the subject for preparation is placed, and the air-tight cover screwed down. The air is then exhausted by means of an air-pump, and when a sufficient exhaustion has been effected, a cock is opened communicating with a vessel containing the antiseptic fluid, which, on being admitted, thoroughly pene- trates the object to be preserved, impregnating even the marrow of the bones. He adds, that the process is useful not only for the prevention of putrefaction, but also in arresting its progress, the' gases generated during putrefaction being expelled from the re- ceiver along with the air, and their place supplied by the antiseptic . March 16.— Mr. Brown, V.P., in the Chair. Read " On an edible Fungus from Tierra del Fuego, and an allied Chilian species." By the Rev. M. J. Berkeley, M.A., F.L.S. Mr. Berkeley describes these two species as constituting a new genus, w^hich he characterizes as follows : — CYTTARIA. Receptacula carnoso-gelatinosa in stroma commune subglobosum, epider- mide crassiuscula vestitum, aggregata ; basi stipitiformi granulata. Cupula peripherica, primo clausa, gelatina distenta, demum epidermide rupta aperta. Hymenium, margine cxcepto, separable. Asci ampli, demum hberi, paraphysilms immixtis. Felum persistens, demum ruptum, margine plus minus reflexo. Sporidia pallida. Genus BulgaricB affine, sed stromate pulvinato ex variis individuis com- posito Sphceriam concentricam quodammodo referens, et hymenio sepa- rabili valde diversum. Certe ad seviem Pezizarum pertinet, perithecio spurio non obstante. Confer Spliceriam jnoriocarpain, Schum. ad Pezi- Linncean Society, 43? aam rkizopodam a clar. Fn'esio ascriptam.

Hab. in Chili in Fagum obliquam, vere et sestate. The first species is noticed by Mr. Darwin (from whom Mr. Berkeley obtained his specimens of both) at p. '298 of his ' Journal and Remarks,' forming the third vol. of the * Narrative of the Voyages of the Adventure and Beagle' ; and Mr. Berkeley gives from Mr. Darwin's MS. notes a more detailed account of his observations made upon the spot. The second species is referred to in a .post- humous list of the plants collected by Bertero (originally published in the * Mercurio Chileno,' and translated in Silliman's ' North American Journal,' vol. xxiii. p. 78), as forming, perhaps, " a new genus approximating to the Sph^ri/s." A further account of this species also is extracted from Mr. Darwin's notes : it seems to be less eatable, and less frequently eaten than the first, which Mr. Darwin describes as forming a very essential article of fopd for the Fuegian. Read also a ** Letter from Joseph Woods, Esq., F.L.S., to Mr. Kippist, on Crepis biennis and Barkhausia taraxacifolia.'^ Mr. Woods is of opinion that the plant described by Sir James Smith in the ' English Flora' and ' English Botany,' by Sir W. J. Hooker in the * British Flora,' by Mr, Babington in the Society's * Transactions,' vol. xvii. p. 456, and by Mr. Mackay in his ' Irish Flora,' as Crepis biennis, is in reality Barkhausia taraxacifolia, di- stinguished especially by the long beak of its achenia, while those of Crepis biennis are, in the words of Gaudin, ** neutiquam attenuata." The stem of Crepis biennis is also less branched and more leafy than that of Barkhausia taraxacifolia, the latter rarely producing a leaf except where there is a branch. Mr. Woods adds, that it is almost certain that we have the two species in England, though the dif- ference has not been noticed. Crepis biennis grows in Kent and Surrey. In a " Note" appended to Mr. Woods's letter, Mr. Kippist states that the authentic Linnean specimens of Crepis biennis from Scania, although too young to have ripe seeds, appear to confirm Mr. Woods's idea, the pappus being quite sessile even in those most advanced, and the stem moderately branched in the upper part, and very leafy below. The two specimens in the Smithian Herbarium, one from Mr. Crowe's garden and the other from Mr. Rose's Herbarium, have the stem much branched, and the pappus apparently sessile, but the achenia are immature. The only developed specimen in Mr. Winch's herbarium is from Dartford in Kent, and has the pappus very decidedly stalked, the stem much branched in the upper part, and only a few scattered leaves in the lower, a branch being produced from the axilla of each cauljne leaf with the exception of one or two of the lowermost, 438 Linnaan Society. Other specimens, gathered near Cobham and Ramsgate, in the same county, and near Moulsey in Surrey, agree with Mr. Winch's plant in their stalked pappus and branched stem, and probably therefore belong to Barkhausia taraxacifolia. The only British specimens in the Society's possession that Mr. Kippist believes to be referrible with certainty to Crepis biennis are two in the Hortus Siccus of Mr. Woodward, with ripe achenia and perfectly sessile pappus; the habitats of the plants are not given, but in all probability they were gathered either in Suffolk or Norfolk. Read also an " Extract from a Letter to John Miers, Esq., F.L.S., from George Gardner, Esq.," dated Rio de Janeiro, Dec. 16, 1840, in which Mr. Gardner gives some account of his journeys in the in- terior of Brazil, and of the collections made by him subsequent to May last. April 6.— Mr. Forster, V.P., in the Chair. Read, an Extract of a Letter from J. Bumham, Esq., to Hyde Clarke, Esq., F.L.S., on a supposed new British Juncus. Read also the commencement of " An Appendix or Supplement to a Treatise on the (Estri and Cnterebra of various Animals." By Bracy Clark, Esq., F.L.S., Corresp. Memb. of the French Institute. April 20.— Mr. Brown, V.P., in the Chair. His Grace the Duke of Northumberland, F.L.S., sent for exhibi- tion a specimen of the fruit of Chrysophyllum monopyrenum, Sw., from his living collection at Syon House. W. Felkin, Esq., F.L.S., sent for exhibition specimens of Sea- Island Cotton grown in a cotton-mill situate in the centre of Man- chester, accompanied by a Notice of the circumstances under which the experiment was made. The details have been given in the Transactions of the British Association. Read the conclusion of Mr. Bracy Clark's "Appendix or Supple- ment to a Treatise on the (Estri and Cuter ehrce of various Animals." The first memoir to which this paper is intended as an Appendix appeared in the third volume of the Linnsean Transactions, published in 1796. This memoir was republished by the author with consi- derable additions in 1815, and a Supplement was added in the fol- lowing year. Since that period much has been published on the sub- ject, and Mr. Clark is desirous in consequence of making some ad- ditions and corrections to his former publications. After adding to and modifying some of the passages contained in them, he examines the validity of several species of the genus (Estrus proposed by writers. He suspects CE, Trompe of Modeer and (E, ericetorum of Leach to be severally the males of (E. Tarandi and (E. Bovis. He believes CR. Pecorum of Fabricius to be only a dark- coloured variety of (E. nasalis, L. {(E. veterinus, B. CI.) ; and is sa- tisfied by an examination of the original specimen, that Dr. Leach's (E Clarkii is nothing more than a very light- coloured variety of the same species. He also regards (7
