Fig. 1.—Diaspis cinnamomi, Newst. var. mangifere, Newst.; a, outline of female ; 
b, margin of pygidium of adult female. 
This variety differs from typical examples of Diaspis cinnamom/, Newst., in 
the following particulars :—The anterior lateral groups of cireumgenital glands 
are much more numerous (26-29); the cephalothoracic area is considerably 
broader than the widest abdominal segment, and the median lobes are non-serrated. 
The puparia of the females are typical, and may be distinguished by the median 
black stripe in the larval pellicle.
