HARDWICKE'S SCIEN CE- GOS SIP. 



NOTICES TO CORRESPONDENTS. 



H. Allinghaji.— Your specimen is the Centuary (En/fhrca 

 centaurea). The book vou mention is a gpood one, but not 

 equal to Dr. Hooker's student's " Flora of tlie British Islands," 

 at the same price. 



W. HowcHiN.— The back of the leaf sent is covered with 

 " Oak-spangles," a gall produced by a species of Cynips. 



C. BucKNAi.i..— You cnnot do better than procure Dr. 

 Hooker's " British Flora." Cooke's " Hand-book of British 

 Fungi," published in two vols. (Macmillan, London), is 

 the best and cheapest book on that subject yet published. 

 Price, a guinea. 



TnoMAS Wir.LiAMS.— Your letter came to us marked 

 " Received open at General Post-Office." It contained 

 nothing but the note, and the envelope was unstamped. 



Maberley will hear of rare butterflies by applying to Mr. 

 John Purdue, Ridgeway, Plympton, Devon. 



Frank Allen.— Walker's " Insecta,"and Steiihens' works 

 are the only books we know of that treat the subject fully. 

 Wood, in his " Insects at Home," treats on the more common 

 dipterous insects. 



John Dawsov.— Many thanks for the specimens of Isoctes 

 hystrix, which reached us in safety. 



E. Clarke.— The leaf of the Potamogeton had on it the 

 young of the Lymnea. 



G. R. Wynne.— It is not unusual for the leaves of the 

 Horseradish to assume a pinnate form under the circum- 

 stances you name. It may be due to the raiiid growth of the 

 leaf. (See Masters' " Vegetable Teratology.") 



'VT.'W.— \t\% Puccinia malvacearum, not found in Britain 

 till during the present year.— M. C. C. 



H. W. 1.— Mr. Hobkirk's "Synopsis of British Mosses" 

 may be had of Hardwicke, 192, Piccadilly. Accept our thanks 

 for seeds oi Angelonia. 



Erratum.— In Mr. J. O. Harper's "Exchange" of last 

 month, the word " larva " appeared instead of " hair.'' Those 

 interested will please note the correction. 



H. Marshall Warp.— The minute yellow dots on hop 

 leaves are apparently lujnUine, from the strobiles of the hop. 

 J. HoncsoN. — 1. Not quartz but calc-spar,as maybe told 

 by the rhombic cleavage of the mass ; -2. Iron pyrites, with 

 radiated structure; 3. Yellow cubes of fluorspar {Calcic 

 ftunte). 



M. U. T.— You will find teratological subjects treated in 

 the new edition of Cooke's " Manual of Botanic Terms." 

 (London : Hardwicke.) 



E. C. J.— Oa Solidopro is Puccinia virgaurece ; on Anagn/lis 

 not a fungus, — only diseased tissue. 



R. V. Trllan.— The lichens are— 1. Verrucaria rhieren ;— 2. 

 destroyed in transit, but looks like Ptinnaria nehulosa. 



E. W.— The Caterpillar is that of the Golden Sallow-moth 

 (Xant/iia fulvago). 



H. J. McGiLL.— All the Caryop/iyllaceiE, of which the 

 Lychnis is a member, are liable to the modification you 

 mention. 



S. T. P.— The objects on Oak-leaf are not fungi, but 

 " Button-galls," formed by an insect a species of Cynips. 

 See " Half hours in the Green Lanes." (London : Hardwicke.) 

 Rkv. S. a. Bremnan. — The drawing represents the cater- 

 pillar of the Pepper Moth {Amji/iydnnis Oirfuliiriii), a common 

 species. This twig like form of caterpillar is common to a 

 very large number of species of moths of the family Gcodic- 

 ti-idrB. They do not make the trees Jipon which they feed 

 unhealthy.- C. G. B. 



J. P. Gre ELY. —These eggs appear to be those of the 

 common Drinker Moth {Odtinestis potatoria), but infertile and 

 shrivelled.— C. G. B. 



E. H. S. — There is a most exhaustive paper called " Con-- 

 tributions to the Klnra of Berkshire," by Mr. James Britten^ 

 F.L.S., of the British Museum, pablished by the local society] 



John Turner. — Mr. Grattann is now publishing such a 

 work as you mention in monthly parts. — Address, "Bazaar " 

 Office, Wellington-street, London. 



C. V. Green. — Your specimen is the Nodding Bur-Mari- 

 gold (Bidens vernuu), a member of the Compusito'. 



W. B. G.— The objects on the fern are the Scale-insects, 

 aspec'es of Cori-iis, of which the body of the female becomes 

 a sort of cocoon under which the eggs are hatched. 



C. C. — It is difficult to decide from so small a specimen, 

 but it looks like the Lower Chalk more than anything else. 



E. L.— We should feel obliged by your sending us a spe- 

 cimen.
