with, of an darlier appearance of fresh imagos than in the 

 latter part of June. They continue to emerge during July, 

 and even, in some seasons, to the end of August. (There are 

 some Entomologists who look upon V, Urticaj as double- 

 brooded, an opinion which I have not seen confirmed by 

 adequate proof). South and west of London this summer 

 the larvae of V. Urticfe were so numerous that it is no ex- 

 aggeration to say they might have been gathered by thou- 

 sands if wanted. V. Atalanta, which was very scarce last 

 year, has also appeared in its usual numbers. — John li. S.

191. Note on Orgyia antigua. — About ten days ago I 

 found in my garden a cocoon of a female of this moth spun 

 up in a plum-leaf. The young larvae were, singular to say, 

 in the act of escaping from the eggs. This may have been 

 merely an exceptional case, or it may be proved hereafter 

 that a certain part of the eggs deposited in the summer are 

 hatched the same season. — Id. 



192. Colias Edusa at Greenhiihe, Kent. — While beating 

 hedges for Geometrae, at Greenhithe, on the 22nd of July, 

 along a road near Stone Wood, a fine specimen of C. Edusa 

 floated rather languidly past me, enabling me at once to de- 

 cide upon its cognomen. My brother, who was with me, 

 immediately gave chase, but the insect, alter proceeding a 

 short distance along the road with its usual swiftness, passed 

 over into the wood, where we lost it among the trees. — Id» 



193. The '■'' Blown-over''^ Theory. — It was about such a 

 summer as this, some few years ago, that several fine speci- 

 mens of Pieris Daplidice were taken round about Brighton ; 

 and this recals to my mind the " blown-over " theory, and I 

 must confess my opinion is very much altered about it. 

 Last year, in July, I was with a friend on Shoreham Pier; it 

 was a still, hot day, with hardly a breath of air, and now and 

 then the common P. Brassicae and P. Rapae would lazily fly 

 in. The flood-tide set in about 3 p.m., with a gentle breeze, 

 and then came a host of the above-named butterflies, with a 

 few of P. Napi ; there must have been hundreds arrive within 

 a very short space of time ; but what surprised my friend and 

 me was their alighting or settling on the sea with expanded 

 wings, and the ease with which they rose again : we saw the 

 same butterfly settle and rise again as many as four or five
