TO CORKESPONDENTS. 



A few instructions respecting Communications seem to require repetition : 

 it is probable many new subscribers have not seen them. 



1. Notices of Exchange must be forwarded on or before the 24th of the 

 month. 



2. They must contain no irrelevant matter, but simply the names of 

 Duplicates and Desiderata. The generic names to be omitted, unless the 

 same specific name occurs twice. 



3. They must be signed with Name and Address at foot : this informa- 

 tion when given in a separate note or on a separate piece of paper is subject 

 to be mislaid, and thus causes unnecessary trouble. 



4. Eecords of Captures should be sent as early as possible ; but as these 

 are interesting to the general reader as well as to the sender, the same rigid 

 rule of exclusion will not be enforced as in the case of Exchanges. The 

 Editor claims a discretionary power as to admitting late contributions. 



5. All Communications intended for publication must be written clearly, 

 and on one side of the paper only. 



6. Comp)laints of Irregularity in delivery through the trade must be 



addressed lo the Publishers or to your own Bookseller. Irregularity in the 



delivery of subscribers' copies may be addressed to this Office.

W. Luff, jun., and others. — Full information as to all postage is to be 

 found in the ' British Postal Guide,' published quarterly, price Is., to be had 

 of all booksellers and the principal post-masters. The following is an extract: — 



" Pattern S Sample Post — Inland. The Postage is now one halfpenny for 

 every weight of 2 oz. or fraction of that weight ; but the Pattern or Sample 

 Post is restricted to bond fide trade patterns or samp)les of merchandize. 

 Goods sent for sale, or in execution of an order (however small the quantity 

 may be), or any articles sent by one private individual to another which 

 may not actually be patterns or samples, are not admissible. 



" Patterns or Samples, when practicable, must be sent in covers open at 

 the ends, so as to be easy of examination. 



" There must be no writing or printing upon any packet except the 

 address of the person for whom it is intended, the address of the sender, 

 a trade-mark or number, and the price of the articles; * -y- * these 

 particulars may be on labels attached to the samples." 



A trial box of insects, packed strictly in accordance with the Post-Office 

 directions, weighing just under 4 oz., stamped with one penny stamp, and 

 marked on the direction label Samp)les of Insects, has been dtlivered 

 without remark. 



Names of Moths. — I forward per sample post a very common caterpillar ; 

 nearly every thistle in the fields is covered with them, and shall be very 

 much obliged if you will name it for me. I enclose wings of some very 

 common moths I cannot name : the larvae of Nos. 4 and 6 have done great 

 mischief in the garden this year. — James Pickles; 12 & 13, Warehouse Hill, 

 Leeds, September 13, 1870. 



[The caterpillar is Hadena Pisi. The moths are»— 1. Xylophasia poly- 

 odon ; 2. Apamea basilinea ; 3. Anchocelis litura; 4. Mamestra Brassicae ; 

 6. Mania typica ; 6. Melanippe fluctuata. — E. Newman.] 



Management of Hybernating Larvm. — Would any of your correspondents 

 give a few hints as to the best means of keeping Bombyx Rubi and other 

 hybernating larvae over the winter? — J. Hamilton, Secretary to the New- 

 castle-on-Tyne Entomological Society.
