REMARKS. 



This species is fairly common and widely distributed. It is most 

 often found on Oleander, but curiously enough is not found on any 

 species of Citrus. This may be because the lemon the species that 

 it favours most is very little grown in this country. It is very fre- 

 quently found on lemons imported from Cyprus and other Medi- 

 terranean countries.

Bosaceaa Prunus armeniaca (Apricot), Rosa sp. (Rose). 



PART OP PLANT ATTACKED.

REMARKS. 



This species has only been collected at Alexandria. Microscopic 

 preparation of my specimens agree with Green's description of Diaspis 

 amygdali Tryon (loc. cit.) rather than with Newstead's Diaspis pentago- 

 na T.T., but according to Femald D. amygdali Tryon is a synonym 

 of D. pentagona T.T. and so I have adopted the latter name.
