HARDWICKE'S SCIENCE-GOSSIP. 



[Oct. 1, 1869. 



NOTICES TO CORRESPONDENTS. 



G. E. C, J. W„ S. J., and B. T.— Books are ineligible for 

 notice in our exchange column. 



L. R. R. — The plant is Corydalis claviculata. 



G. C. — The caterpillar is that of Chterocampa cclerio. 



W. B. L.— Newman's " British Moths." 



J. p.— The mycelium of a fungus. It is often more or less 

 phosphorescent ; boys call it " touchwood," and know of its 

 luminous property. 



M. F. D. — Eggs of the lace- wing fly (Chrysnpa). 



C. W. — See notice of Elm-galls in Science-Gossip for 

 1867, P- 1/. They are produced by aphides. 



H. C. S.— Write to Mr. W. R. Tate, Grove House, Hackney, 

 and he will render any assistance. 



J. R. — It is the bog pimpernel. 



C. S. G. — The puss-moth (Centra vinula). 



F. H. — The swarms of ladybirds have been so fully noticed 

 in all the newspapers, that it is unnecessary for us to enter 

 upon the subject. 



A. T. B.— " Sowerby's English Botany," 3rd edition, vol. ii., 

 p. 137- 



H. E. W. — Undoubtedly we should consider " pepsine " free 

 from the conditions necessary for trichini. 



D. G. W. — There is not likely to be a new edition of the 

 lectures you name. The book " Life on the Globe," by Pro- 

 fessor Phillips, we do not know. There is one with that title 

 by David Page. 



H. W. H. C— No. 1 is Gemellaria loricata. 2. Crista ehur- 

 nea. 3. Ctinda rep tans. 



W. K. — We should recommend you to purchase a storm- 

 glass, rather than "dabble" in making them; especially as 

 makers will take care not to tell everything that is essential 

 to success. 



W. H. L.— For particulars of fly-mould (Sporendonema 

 musca>), see the first number of Sciknce-Gossip, 1865, p. 11. 



J. D. — Dr. Ormerod's " Natural History of British Social 

 Wasps," was published in 1868 by Longmans & Co., we think 

 at half-a-guinea. 



R. A.— Don't use so much balsam. Try a single drop on a 

 slide, then place the " Aregma " on the balsam, in the centre ; 

 in a short time put on the cover. We have mounted hun- 

 dreds of slides of rusts without the least difficulty. 



J. H. — We have no such intention ; nor do we intend 

 pledging ourselves to any special course for the future, ex- 

 cept to do the best we can for all our readers. 



J. R. E. had better address his query to a special Horticul- 

 tural journal. 



A. C. — The larva of either Agrotis exclamationis or Agrotis 

 segetum. — H. G. K. 



E. T. S. — The spider and egg cocoon are of the species 

 Theridion pallens, Bl.— 0. P. C. 



D. H. S. (Worthing). — The specimen sent was composed of 

 the confervoid filaments of a moss in their resting state in 

 dry weather ; on the approach of winter and spring they alter 

 their character, and become green as they grow ; a full ac- 

 count may be found in a paper by Dr. J. Braxton Hicks in 

 Linn. Trans, for 1862. 



R. H. — No 1. Triglochin palustre,L. 2. Listera ovata, R.Br. 

 — B. 



H. W. G. — No. 1. Erigeron Canadensis, L. The flower 

 heads are never yellow strictly speaking. 2 and 3. Not un- 

 common. 4. Oplismenus (Echinochloa) cms galli, oxfrumen- 

 taceus, K. — B. 



F. G. S.— The " Richmond and North Riding Naturalists' 

 Field Club " is in active operation under its excellent presi. 

 dent, Edward Wood, Esq., of Richmond. 



T. Buck (Chelmsford). — It is impossible, without actual ex- 

 perience, to answer your question. It would certainly be best 

 to keep the eggs moderately damp — say in moss. The larva 

 is stated to be full grown in April, so it probably hatches 

 late in the summer or autumn. Young larvse may be seen 

 quite early in the spring ; these have, doubtless, hybernated. 

 You are, of course, aware that the glowworm, both as a 

 larva and perfect insect, is carnivorous, feeding on snails and 

 other mollnsca. In Science Gossip for 1868, p. 73, you will 

 find an article on mounting, &c, Culeoptera, which will pro- 

 bably enable you to preserve "water insects " for examina- 

 tion. But you do not state what water insects. — E. C. R. 



I. G. H. — The small beetle "abundant on the leaves of 

 Zizyphus rugosa on the western ghauts of India," is Platy- 

 pria echidna, Guerin, one of the HispidiB.—E. C. R. 



M. D. B. (Leamington). — Having had experience of the 

 kind of rubbish you send as good slides in exchange, and — 

 charitably believing that you know no better — we decline 

 your offer to " Portland " with thanks. 



St. E. — Mr. Wheldon, Great Queen Street, London, W.C., 

 has a good supply of second-hand books on natural history. 



J. C. D. — No. l. Thuidittni tamariscinum. 2. Bartramia 

 pomiformis. 3. Tortilla muralia. — R. B. 



F. M. C- -The moss is Bryum pseudotriquctrum. — R. B. 



J. D. — The bees sent are Odynerus parietum (male), and 

 Andrena fucata (male). — F. S. 



H. W. H. C. - -No. 4 is Lophocolea bidtntata.— R. B.
