82 THE ENTOMOLOGIST. 



Forest in the autumn (they have been kept out of doors all 

 the winter). As you give, in your ' History of British Moths,' 

 August for their appearance, are they double-brooded ? or is 

 it a freak of nature ? If you will kindly answer this in next 

 month's 'Entomologist,' I shall feel much obliged. — F. 

 Travgmar; 20, Tidy Street, Brighton, April 4, 1872. 



Mr. Merrin gives June for the imago, and August for the 

 larva. 



Rose Beetle. — Is it usual to find specimens of this 

 Coleopterous insect hybernating in the earth ? A few days 

 ago I dug up two in a torjjid state, which revived after being 

 placed for a few hours in a warm room. The fact of such 

 hybernation is probably well known ; but I do not recollect 

 ever meeting with this particular species in such a situation 

 before. — G. Bentleij Corbin. 



It had probably undergone its final change in the ground, 

 which is not unusual. 1 do not think Cetonia ever enters the 

 ground to hybernate. 



Posting Boxes. — Even the most strongly-made boxes 

 (Entom. 102, p. 58) get smashed in their transmission through the 

 post, as most of us know from experience. A very good plan 

 is to cover the boxes with calico or some such material, 

 using glue to secure it. If the boxes have been in use they 

 should be thoroughly cleaned from any greasy matter, or the 

 glue will not hold so well upon them. In the case of a box 

 where the lid and bottom are formed of cork, I cannot speak 

 so positively ; but if a box is wholly formed of wood on the 

 outside it is surprising how much its strength is increased by 

 the plan I have named. — G. B. Corbin; Ringwood. 



Post Boxes. — I would recommend boxes made of some 

 light strong wood, to admit of specimens top and bottom of 

 box, and of such dimensions suitable to allow of a casing of 

 cotton-wool placed round ; then enclose inside a tin case. Haif- 

 a-pound or pound mustard tins might be brought into use, or 

 such cases as Bragg's charcoal biscuits are sold in might 

 be requisitioned: these, with an additional roll of cotton-wool, 

 may be safely adopted. I have used cardboard and leather 

 cases in the same way, and they have carried well. If for a 

 large number of insects, I should say pack well, and enclose 

 inside a much larger box, and send per rail. — J. Bryant; 

 63, Old Broad Street, B.C., March 18, 1872.
