 At the end of September, 1892, I received some ? scales of an 

 Aspidiotus from Mr. A. T. Gillanders, who had found them on the bark 

 of an oak tree near High Legh, Knutsford, Cheshire. Although they 



differed in colour 

 from the descrip- 

 tions given by the 

 various authors, a

Mr. Gillanders asking him to look for the (^ scales on the leaves of 

 the trees, which he did, and by return of post sent several leaves on

 visited the locality, and procured a quantity of both (^ and $ scales, 

 which, although they occurred on a single tree, were very abundant, 

 both on the leaves and the branches. There was this peculiarity, 

 however, the males were entirely confined to the leaves, and the females 

 to the branches, sometimes many feet away from their partners. This 

 is of importance, and it is quite possible that the females, to a certain 

 extent, may have been overlooked by the various authors who have
