SYNOPSIS OF SUB-FAMILIES. 67 



sions recently given by Mr. E. E. Green (Coccidae of 

 Ceylon, pp. 16, 17), adding thereto the subdivision 

 Margarodinx, which, from the absence of mouth-parts 

 in the adult female, I agree with Professor Cockerell 

 (" Tables for the Determination of the Genera of 

 Coccidse," Canad. Ent., vol. xxxi, pp. 273 279) 

 naturally calls for a separate division. I should also 

 add that Mr. Green places the Concha spinse before the 

 Diaspinae ; but it seems to me, although I may be quite 

 wrong, that the insects comprising this sub-family are 

 more naturally placed in the ascending order above the 

 DiaspindS, and I have therefore made this additional 

 deviation from Mr. Green's classification.
