NOTICES TO CORRESPONDENTS. 



All communications relative to advertisements, post-office 

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

 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. Wo notice whatever ran be taken of communica- 

 tions which do not contain the name and address of t/ie 

 writer, not necessarily for publication, if desired to he 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 by an 

 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. 



G. R. W. — Probably you might obtain either Canadian En- 

 tomologist or American Entomologist of Triibner & Co., Pater- 

 noster-row, London. 



M. J. G.— No. 2. Part of the moss (Racomitrium). i. Basal 

 portion of Antennularia untennina. 



R. L. C— Burmeister's "Manual of Entomology" (Chur- 

 ton, London, 18361. 



F. E. N.— Certainly not. 



J. W". — We cannot commence the practice of naming foreign 

 plants. 



C. E. O.— Our rule is " one at a time.'' 



T. C. D. — We figured a similar triple pear in our volume for 

 1367, page 62. 



W. H. L. — The true whitebait, according to Dr. Gunther, 

 is a distinct species. Mr. F. Buckland states that much of 

 what is sold as whitebait consists of the fry of several fish. 

 See Land and Water for further particulars. 



J. R. P. — If our correspondents read Gossip properly, they 

 would not repeat queries already, and recently, answered; 

 for "food for tortoise," see page 140. 



G. H. H. — For the very good reason that the Cirripedia 

 are not Molluscs. 



W. K. — The best way of satisfying yourself is to keep tor- 

 toises and watch their habits, which you will find much 

 more instructive and interesting than sending us a string of 

 queries. 



Ruddy Sheldrake in Norfolk. — Dr. L. informs us that 

 the bird alluded to in our last was a veritable " escape." — See 

 ahop. 184. 



J. A. B. — We do not care to introduce the subject. 



J. R.— To print the paper read at your club would be merely 

 to repeat what we have already done. See " Pin-centres and 

 Rose-centres " in our volume for 1866, page 106 ; and nume- 

 rous communications on cowslips, oxlips, and primroses 

 during two or three years. 



F. R. M.— The moths are Trochilium tipuliforme. — H. K. 

 M. H. O. P. — The beetle is Phytonomits Rumicis which 



may he bred from the dock, — C. W. 



W. R. M. — The beetle is Lampyris noctiluca, male. The 

 female is wingless and luminous, and is the common glow- 

 worm. — C. W. 



G. E. Q.— The gnat appears to be Culex pipiens. — C. W. 



J. P.— The insects hatched from eggs found on the bramble 

 are the larvre of some Hemipterous insect (Tree Bug). — C. W. 



W. G. — No aphis left in the box to determine the species. — 

 C. W. 



W. H. — The grass is a very poor, starved specimen of Gly- 

 ceriafluitans. 



T. A. H. — The ferns are Lastrea. dila.tatu and Lastrea Filix- 

 mos, var. interrupta, Moore.— J. G. B. 



J. R. (Hitchin). — Not uncommon malformation of Trifolium 

 repens, the pistil being foliaceous, and the calyx with a ten- 

 dency to become so. — B. 



E.C.J. — No. 1. Polytrichum juniperinum. 2. Campylopus 

 flciuosus. — R. B. 



J. L. — " Honey-dew '' is applied to the extravasation of sap 

 which takes place in hot, dry weather. The same term is also 

 given to the clear honey-like fluid which is ejected by 

 aphides, or plant-lice, from pores at the extremity of their 

 bodies. The Aphis which infests wheat at this season is 

 Aphis arena. Some information is given in Curtis's " Farm 

 Insects " and Westwood's " Introduction to Modern Classifi- 

 cation of Insects." In the latter — " The anal tubercles 

 secrete a saccharine fluid, of which ants are very fond ; and it 

 is this fluid dropped upon the adjacent leaves, or the extrava- 

 sated sap flowing from the wounds caused by the puncture of 

 the insects, which is known under the name of Honey-dew." 

 See also the correspondence in Gardener's Chronicle, July :ird, 

 loth, and 1 7th, l8(i<). Some persons believe that " Honey- 

 dew'' is wholly, and always, caused by aphides.
