Icerya aegyptiacum, Doug. 



Zanzibar : on young date palm, 15.iv.13 (Dr. W. M. Aders). 



This is the first record of the occurrence of this pest in Zanzibar. The examples 

 were nearly all young females. 



Icerya maxima, Newst. 



Uganda: Ngamba Is., Lake Victoria; on tree trunk, 28.vi.14 (Dr. G. D. H. 

 Carpenter). 



These specimens have a larger number of glands than typical examples ; otherwise 

 the structural characters are specifically identical. Unfortunately the external 

 coverings had almost completely macerated in the preservative, so that nothing can 

 be added regarding these.

Madras Pres. : Megapatam ; on rice, xi . 1914 (T. V. Ramakrishna per E. Ballard). 

 British Guiana: Georgetown; on sugar cane, 27.vii.16 (G. E. Bodkin). 



The distinguishing features of the adult females are : the presence of a pair of dark 

 brown or piceous plates between the 2nd and 3rd free abdominal segments on the 

 venter ; the great length of the transverse coxal sclerite on the anterior legs ; and the long 

 bristles on the segment above the anal lobes. The second-stage females are similar, 

 but the anterior coxal sclerites are slightly longer relatively, as compared with the 

 width of the coxae ; and there is an additional group of long abdominal hairs above 

 the anal lobes.
