Fig. 1. — Diaspis cinnamomi, Newst. var. mancjiferce, Newst. ; a, outline of female ; 

 b, margin of pygidium of adult female. 



This variety differs from typical examples of Diaspis cinnamomi^ Newst., in 

 the following particulars : — The anterior lateral groups of circumgenital 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.
