ADDITION OF BRYOPHILA PAR TO THE BRITISH FAUNA. 
By Witiram Warren. 
More than twenty years ago I took a pair of a Bryophila at 
Cambridge, which at the time seemed to me to present decided 
points of difference from Glandifera, but both Mr. F. Bond and 
the late G. R. Crotch, who saw them, referred them to that 
species as a variety, and I submitted to their decision. I have 
taken one or two at intervals since; but last year, having captured 
ten, quite fresh, and observing new points of difference, I sent a 
pair to Mr. Barrett, who forwarded them to Professor Zeller. The 
latter, at first, returned them as Glandifera, var. Par, but has 
since, Mr. Barrett informs me, agreed with him that they 
constitute a distinct species. I will therefore now proceed 
to give, as far as mere description can do it, the main points by 
which I think the two species may be differentiated. 
Ist. The lines and markings of B. glandifera are much more 
sharply and distinctly marked than in B. Par, which has, so 
to speak, a more mealy look. 
2nd. Though the lines and markings of the two insects 
are exactly alike, B. Par has all the lines starting as dark spots 
on the costa, and a decided dark line at the base of the cilia of 
both wings, but especially the hinder ones. 
3rd. B. glandifera retains its green tinge after death, which 
continues for years if excluded from light. B. Par, which, when 
fresh and alive, is of a much paler green, often with a beautiful 
pink tinge, fades directly it is killed, or when worn, to a dirty brick. 
colour.
