VARIETY OF POLYOMMATUS PHL.EAS. 

 By Walter P. Weston. 



I'OLYOJIMATUS rHI,.l!AS (VARIETv). 



This beautiful variety of Polyoninialus Phlceas, in which 

 the usual spots in the fore wings are replaced by a broad 

 black band extending entirely across the wings, was taken by 

 Mr. A. Marriott, on the 7th of August, 1876, when flying 

 along a piece of waste ground in the neighbourhood of 

 Finchley, Middlesex. The lower wings are marked as usual, 

 and the markings on the under side are entirely normal, 

 without showing the slightest trace of the black band so 

 conspicuous on the upper side. Mr. Marriott informs me 

 that even when on the wing this black band was very 

 perceptible, giving the insect a darker and totally different 

 appearance to the type. My thanks are due to Mr. Marriott 

 for his kindness in allowing me the loan of this insect for the 

 purpose of figuring in the 'Entomologist.'
