October 'drd. — Mr. L. W. Newman, F.E.S, exhibited slate-grey 

 males of Agriades thetis {admi.isj and one showing a curious mixture of 

 the two colours slate-grey and brilliant blue. The grey form has 

 occurred before, but the mixed specimen is unique; all were found at 

 one spot. The structure of these grey insects is extremely delicate, 

 and to secure perfect specimens they must be taken drying their wings; 

 otherwise they are invariably badly damaged. Mr. Newman also 

 exhibited Agriades coridnn. vars. rugstuufnsis, inaequalis, and iiiipar, five 

 having left side small wings and seven right side small wings, several 

 females with blue streaks and also two with tawny streaks on the
