 to the Zoologist : — 



" For eighteen years I possessed four bleached speci- 

 mens only of Tliecla W. Album, having vainly endea 

 voured to procure others, when, in 1827, as elsewhere 

 recorded, I saw the insect at Ripley, not by dozens only, 

 but by scores of thousands ' and although I frequented 

 the same locality for thirteen years subsequently, some- 

 times in the season for a month together, I have not 

 6ince seen a single specimen there ; but in 1833 I 

 caught one specimen at Madingley Wood, near Cam- 

 bridge."
