176 THE ENTOMOLOGIST. 



thought this might be worthy of notice, as in your * British 

 Moths' you slate the time of the appearance of the moth to 

 be June. — Samuel James Capper ; Huyton Park^ near 

 Liverpool, May 17, 1872. 



Orthosia Ypsilon. — Having reared a considerable number 

 of this insect this year, and being too busy to kill them all as 

 they emerged, I had left some in a large cage together one 

 evening, and on going to see what was out, after dusk, was 

 surprised to see a pair in copula : this has occurred three 

 times since, and 1 have obtained a iew eggs. Is it not 

 unusual for Noctuee to pair so readily in confinement? 

 There was no sponge of sugar or twig of the food-plant in the 

 cage. The eggs are laid under a transparent coating, like 

 those of S. Salicis, but differing in being orange in colour and 

 not white. — Bernard Lockyer. 



Reproduction of Aphides in equable Warm Climates. — 

 Has this subject ever been attended to? In temperate 

 climates, with alternation of seasons warm and cold, it is 

 well known that the viviparous broods of Aphides succeed 

 each other so long as food continues plentiful and the tem- 

 perature permits of it; but the organic mode of reproduction 

 is brought to a stop by the scarcity of food and accession of 

 cold, when sexual individuals appear and eggs are again 

 laid. By means of artificial heat, however, Kyber kept up 

 the viviparous generations of Aphides for four years, when 

 organic reproduction seemed to be as active as at any 

 previous period ; and hence what some consider to be the 

 repetitive prolongation of individual life would seem to be 

 capable of indefinite continuation, as with plants multiplied 

 by layers or cuttings. Under the equable climate of at 

 least some equatorial regions, the conditions artificially 

 applied by Kyber might occur naturally, and I am unaware 

 that any observations have been made on the Aphides under 

 such circumstances. — Edward BIyth. 



Calnsorna SycJiophanta near Penzance. — This rare British 

 beetle was reported to the 'Zoologist' some years ago as 

 having occurred close by Penzance: that specimen was 

 found dead in a pathway. I have just seen a specimen 

 alive, which Mr. Vingoe's son found yesterday near this 

 place, rather less in size than the first, but exactly resembling 

 it. — Edward Ilearle Rodd ; Penzance, July J 1, 1872.
