MEGANOSTOMA. 219 



accounts were published of its having been taken in company 

 with E. hyale and E. kirbyi between Brighton and Lewes ; 

 near York ; near Ipswich ; and in the West of England, near 

 the confluence of the Avon and the Severn, in August and 

 September. Dr. Scudder thinks that the Butterfly might have 

 been introduced into England, maintained itself for a few 

 years, and then died out again ; but it is more probable that 

 the first reputed British specimens were American, and that 

 when attention was called to the subject, specimens of one or 

 other of our British species were mistaken for it. Similar 

 errors constantly occur even at the present day, (an instance is 

 mentioned in the " Entomologist's Monthly Magazine " for 

 July, 1895, of a specimen of Pontia dapUdice being found in 

 an old Staffordshire collection labelled " sinapis,") and such 

 errors must have been far more common fifty or sixty years 

 ago when there were hardly any books on Natural History, 

 even on British Butterflies, than now, when they are plentiful. 

 It is not likely that a Butterfly, said fifty or sixty years ago to 

 have been taken in all parts of the country, should have dis- 

 appeared so utterly that not a single specinien has been heard 

 of since. Besides, it is positively asserted by the Rev. W. T. 

 Bree, in " Loudon's Magazine of Natural History " for May, 

 1832 (vol. V. p. T^n^ note), that the so-called specimens of 

 E. europome^ said to have been taken between Brighton and 

 Lewes, were only E. kirbyi.
