HARDWICKE'S SCIENCE- GO SSIP. 



NOTICES TO CORRESPONDENTS. 



We must remind oar friends, who make use of this column, 

 that the following rules should be strictly adhered to : — 

 First. That perfect specimens be sent. Secondly. That all 

 the information as to habitat, &c, that the inquirer can give 

 should be forwarded with them. Thirdly. To bear in mind 

 that drawings, unless very perfectly executed, are useless, 

 and a tyro is very apt to omit some distinctive characteristic 

 which would enable the examiner to decide the genus and 

 species of the object sent. Lastly. Never to send an object 

 for identification until the inquirer has used his best endea- 

 vours to find out for himself all the information he requires. 

 Questions are very frequently sent, which the slightest effort 

 on the part of the querist, in looking through some elementary 

 treatise, would have given all the knowledge required. 



John Smith (York).— No. I, Donacia serinea, L. (the same 

 as Proteus, Stephens) ; No. 2, Dunacia simplex, F. ; No. 3, 

 Amara trivialis, Gyll. ; No. 4, Amaru plebeia, Gyll. ; No. 5, 

 Pterostichus strenuus, Panz. ; No. 6, Pterostichus vernalis, 

 Gyll. Chrysomela fulgida, Stephens, is the same species as 

 C. graminis, Linnteus, which, of course, is much the older 

 name of the two, and should be used. 



J. B. (Bracken Hill).— The beetle is Niplui hololeuc.us, one 

 of the Ptinidae, now a very common domestic insect in this 

 country. For an account of its swarming, see "The Ento- 

 mologist's Monthly Magazine," vol. ix. p. 119.

 female; No. 5, Bembidium lampros, Hbst.

 nata; 2, Hypnum molluseumj 3, too imperfect for deter- 

 mination ; 4, Hypnum fluitans ; 5, H. resupinatum ; 6, 

 Rhynchostegium ruicifolium ; 7, Dicranum cerriculatnm ; 8, 

 Tortula muralis; 9, Anacalypta Stackeana ; 10, see No. 1;

T. B. (Halstead).— No. 1, Weissia cirrhata; 2, W.mucro- 

 nata. — H. 



J. C. D. (Ripley). — Your moss (No. 2) is Bryum ccespiti- 

 citm, mixed with Hypnum plumositm. No. 1, the flowering 

 plant, is Prunella vulgaris. 



F. S. Sheldon.— Write to the Rev. Thomas Wiltshire, 

 Secretary of Ray Society, 25, Granville Park, Lewisham, 

 S.E.

 pink flower called Lousewort (Pedicularis sylvatica). 



M. D. Beresford.— Your slides will be returned shortly. 

 It is impossible for us to attempt to name plants from a 

 microscopical examination of their pollen-grains, especially 

 foreign plants. No botanist would risk his reputation in 

 attempting such a thing.
