THE ENTOMOLOGIST. 316 



Stragglers had been repeatedly met with in the neighbourhood, 

 especially by my relative the Rev. Wm. Bree, to whom we 

 are indebted for our knowledge of this locality, and who 

 showed me places some distance off where he had seen it. It 

 is a curious fact that Pamphila Comma used to be abundant 

 in the same fields as L. Arion ; and, as far as my knowledge 

 and experience goes, the species absolutely disappeared in 

 the same season as Arion, and has not since appeared. Last 

 time I was at Barnwell Wold the Arion fields were being 

 "improved" by surface-burning, so I doubt your corre- 

 spondent's ever finding it in that locality. My only hope is 

 that, like most gregarious insects, Arion may only have 

 removed its head-quarters, and be still existing a few miles 

 off in similar localities, of which there are plenty, in the 

 neighbourhood, I have observed a considerable difference in 

 the Barnwell Wold specimens and their West of England 

 brethren, the Barnwell Wold specimens being rather larger, 

 with larger and less defined black spots, the wings more 

 suffused with black, and the ground colour not so bright a 

 blue. — Thos. H. Briggs ; 6, Old Buildings, Lincoln's Inn, 

 January 17, 1873, 



Artijicially-veined Specimen of Pie lis Rapce. — It may inte- 

 rest your correspondent, Mr. C. S. Gregson (Entom. vi. 286), 

 to learn that I once possessed a continental specimen of the 

 above insect with the veins of the hind wings coloured green in 

 the manner described. Being at the time doubtful whether the 

 peculiar markings were natural or artificial, I took the speci- 

 men to the British Museum, where my friend, Mr. A, G. 

 Butler, examined it with a lens, and at once pronounced the 

 green veinings to be artificial, and to have been produced by 

 the running of liquid containing colouring matter in solution 

 along the natural wing-veins. — R. Meldola. 



[1 have altered the generic name from Synchloe to Pieris, 

 in accordance with ordinary nomenclature. — E. NewmaiiJ] 



Pieris Brassicce icith Green ]Ving-rays, — Three years ago 

 I took four specimens marked with green, very much the 

 same markings as Mr. Gregson's specimen (Entom vi. 286) ; 

 they are four females. The males I took the same year have 

 no markings. It was my friend, Mr, Leather, who first 

 noticed the markings. Being at that time only a beginner, I 

 did not think the green was unusual. — James Powall i IVal- 

 lasay, Birkenhead.
