1 have been successful in separating a number of the adult 

 females from the enveloping skin of the second stage female and 1 

 find they have the following characters : 



Adult female oval to round, the abdominal segments much 

 contracted after oviposition. In dead and dried specimens the pygi- 

 dium stands out as a perfectly transparent zone with radiating lines 

 like a fan. The rudimentary antennae are situated close together 

 and consist of small tubercles surmounted by four comparatively 

 stout spines : these spines vary somewhat in length and stoutness. 

 Farastigmatic glands confined to one solitary gland and in some 

 specimens altogether absent. Abdominal segments without glands 

 or tubercles but with a verrucose surface. Pygidium broadly trian- 

 gular, margin with several somewhat irregularly arranged* lobes 

 situated slightly within the margin on the ventral surface, rarely 

 projecting beyond it, and a number of short spines. The circum- 

 genital glands 27-33 in number are arranged in a somewhat irregular 

 arched group. Tubular spinnerets and other glands wanting. 



My preparations are all from dried material, and it appears from 

 them that there is no regular arrangement of the lobes and spines 

 of the pygidium.

PART OF PLANT ATTACKED. 



All my specimens are on the stems. 



REMARKS. 



This species was first described by Newstead from specimens on 

 Poplar collected in the garden of the Horticultural Society at Giza, 

 Cairo, and sent by Mr. Willcocks. It is not a common scale, but 

 has been collected in three or four widely separated localities Giza, 

 Beni Suef, Mmya, and Aswan. 



Some specimens of Aonidia parlatoroides Newst. ? kindly given 

 us by Mr. Willcocks I find to be synonymous with F. africana Newst. 

 Mr. Willcocks has kindly given me some more of his original material 

 of this species, as I thought the previous specimen might have been 

 misnamed, but I find that it is undoubtedly F. africana Newst. Un- 

 fortunately I have been unable to trace Newstead's description. The 

 specimens were on willow.
