[Aug. 1, 1868. 



NOTICES TO CORRESPONDENTS. 



All communications relative to advertisements, post-office 

 orders, and orders for the supply of this Journal should be 

 addressed to the Publisher. All contributions, books, 

 and pamphlets for the Editor should be sent to 192, 

 Piccadilly, London, W. To avoid disappointment, contri- 

 butions should not be received later than the 15th of each 

 month. No notice whatever can be taken of communica- 

 tions which do not contain the name and address of the 

 writer,not necessarily for publication, if desired to be with- 

 held. We do not undertake to answer any queries not 

 specially connected with Natural History, in accordance 

 with our acceptance of that term ; nor can we answer 

 queries which might be solved by the correspondent byan 

 appeal to any elementary book on the subject. We are 

 always prepared to accept queries of a critical nature, and 

 to publish the replies, provided some of our readers, besides 

 the querist, are likely to be interested in them. We 

 cannot undertake to return rejected manuscripts unless 

 sufficient stamps are enclosed to cover the return postage. 

 Neither can we promise to refer to or return any manu- 

 script after one month from the date of its receipt. All 

 microscopical drawings intended for publication should 

 have annexed thereto the powers employed, or the extent 

 of enlargement, indicated in diameters (thus : x 320 

 diameters). Communications intended (or publication 

 should be written on one side of the paper only, and all 

 scientific names, and names of places and individuals, 

 should be as legible as possible. Wherever scientific names 

 or technicalities are employed.it is hoped that the common 

 names will accompany them. Lists or tables are inad- 

 missible under any circumstances. Those of the popular 

 names of British plants and animals are retained and regis- 

 tered for publication when sufficiently complete for that 

 purpose, in whatever form may then be decided upon. 

 Address No. 192, Piccadilly, London, W. 



JLypnum exannulatum. 2. Hypnum revol- 



T. S. — A bug known as Tropicorus rvfipes (Hemiptera — 

 Heteroptera). 



F. F. — A Coleopterous larva. 



J. S. T. — Rastelia lacerata, very common this year. 



K. C— The best Botany for an amateur is Bentham's 

 Handbook, price twelve shillings. 



P. G. M.— We cannot open such a discussion, which from 

 its nature can attain no satisfactory results. 



J. B.— No probability of such a work at present. 



J. M. — A species of clearwing, Sphecia apiformis. 



E. J. W.— Most probably, but we cannot name the insect 

 from its nidus with satisfaction. 



J. L. E. — Leaf galls, not uncommon. 



W. P., T. K.— All the American fossils exchanged. 



R. E. C. — Do you innocently believe that the moths you 

 name are rare ? 



G. C. — Your plant is a species of Anagallis, the specimen is 

 insufficient to determine which. A work "in which all 

 loreign plants are described up to the present time "would 

 be rather a voluminous one. You will find a great number 

 of Dicotyledonous exogens in De Candolle's " Prodromus," of 

 which eighteen octavo volumes are published. 



J. S. — Your insect on oats is Aphis avence. See Curtis's 

 " Farm Insects," p. 499. 



T. G. P.— The American Blight is Aphis (Schizoneura) 

 lanigeru, described by Hausmann in Illiger's Mag., vol. i. 

 p. 440 (1801); see also " Knapp's Journal of a Naturalist,'' 

 " Harris's Insects injurious to Vegetation," p. 242, and the 

 British Museum Catalogue of Homoptera, vol. iv. p. 1,048. 

 This latter catalogue contains the descriptions of a large 

 number of Aphides. 



Silk. — Wanted the address of any firm in the habit of pur- 

 chasing raw silk.— T. G. P., 9, Arlington Villas, Clifton. 



J. W.-We know of no popular work on " Cacti." 



"Constant Subscribers" should have learnt by this 

 time that anonymous communications find their way into 

 the waste-paper basket forthwith. 



A. W. R.— Put your insects into a bottle with bruised 

 laurel-leaves at the bottom, and they will soon die. Of 

 course you can attract insects by sugaring. Dr. Knaggs's 

 papers "on collecting, &c," in the Entomologist's Mtmthly 

 Magazine would just suit you. 



J. C. — No. 1. Cladophora albida ; 2. Ceramium rubrum. 



E. C. B. (Portland.) — Weissia commutata. — R. B. 

 T. R. C.—Funaria hygrometrica.— H. B. 



F. W.— No. 1. Rhynchostegium confertum, with Homulo- 

 thecium sericeum. 2. Tortula ruralis.—R. B. 



J. l&.— Grimmia patens, dwaif form.— it. B. 



E. H.— No. 1. 

 vens. — R. B. 



R. G. A. — Hypnum allied to commutation and falcatum, 

 probably new. Send address to R. B., care of the Editor. 



A. J. (Melrose.) — No. 1. Tortula sp. ? belonging to the 

 fallax group, and probably new. Send address to R. B., care 

 of the Editor. 4. Brachythecium rivulare. — R. B. 



F. R.— The rose mildew, now exceedingly common, is 

 S]>ha;rotheca pannosa. 



H. J. R. — Both ferns are Gymnogramma chcerophylla. — 

 J. G. B.
