KKMAHKS. 



This species is extremely common in Lower Egypt, but is not 

 recorded as doing any serious damage. It is not so common in Upper 

 Egypt.

The puparium of the adult female round to broadly pear-shaped, 

 flattish and a transparent white, the sublying yellow female being 

 easily discernible. The pellicles are eccentric, near the margin 

 but within it, yellowish white and transparent. 



I have only two specimens of this scale, and the above description 

 which refers to them, differs from Signoret's description in the shape 

 of the puparium and the position of the pellicles. The microscopic 

 preparations, however, have been identified by Mr. Laing as being 

 typical of Aspidiotus destructor Sign. 



HOST PLANTS. 



On a plant unknown. 



REMARKS. 



The specimen which originally comprised four scales was found 

 by me amongst a number of unidentified species in the collections 

 of the Ministry. It was collected in 1917 in one of the biggest nursery 

 gardens in Cairo on a plant not stated. 



I have visited the nursery in question on three or four occasions 

 but have not found any further specimens of this destructive species^
