132 ROBERT NEWSTEAD. 



Aspidiotus oriental is, Newst. 



British East Africa : no data (T. J. Anderson). S. India : Coimbatore, 

 on tamarind fruit, ii . 1 9 1 1 (T. V. R., per E. Ballard), very heavy infestation; 

 Guntur, on egg-fruit, 20.iii.10 (T. V. R., per E. Ballard), heavy infestation. 



A large proportion of the African adult females have the margin of the cephalo- 

 thoracic area chitinised, a character not noted in the type lot, but present also in 

 examples from Southern India. 



The incorporation of the epidermal layer of the fruit in the Coimbatore puparia has 

 given them a distinctly russet-red colour. The three large bilateral squamae in nearly 

 all of the examples examined are almost entirely free from the minute lateral serrations 

 which may be clearly seen in typical examples ; otherwise the structural characters 

 are specifically identical. The puparia of the Guntur females are much more robust 

 than those of the co-types, and bear a striking resemblance to those of A. cydoniae, 

 Comst. 



Aspidiotus (Chrysomphalus) rossi, Mask. 



S. Africa : Modderfontein ; on Eucalyptus sp., 1913 (D. (TEmmerez). 



Aspidiotus (Pseudaonidia) tesseratus, d'Emm. 



Jamaica: on Matyba apetala, Nectandra coriacea, Gr., Trophis racemosa, Urt., 

 1916 (A. H. Ritchie) ; all heavy infestations. 



Aspidiotus (Pseudaonidia) trilobitiformis, Green. 



S. India: Coimbatore, viii.1912 (T. B. Fletcher). Uganda: Kampala, on 

 oleander, 20.vii.15, on mango, 20.vii. 15 (C. C. Gowdey). 



Aspidiotus (Chrysomphalus) triglandulosus, Green. 



S. India : Bangalore : " attached to scabs on Jack leaf," vi. 1912 (T. B. Fletcher). 



Aspidiotus (Selanaspidus) silvaticus, Lind. 



Uganda : Entebbe, on Citrus aurantium, 7.ix.l3 (C. C. Gowdey). 



Female puparium : More or less circular or somewhat deltoid when arrested by the 

 prominent veins of the leaf ; thin and flat. Exuviae central in the circular forms, 

 and submarginal in the deltoid ones. Those on the upper surface of the leaves russet- 

 buff, with broad pale margins and slightly darker exuviae ; on the underside more 

 opaque and brownish buff, with obscure buff-yellow exuviae. Greatest diameter 

 2-2*6 mm. Female adult: Very broadly pyriform ; thoracic constriction slightly 

 less than one-third the entire length of the body ; thoracic tubercle apparently absent. 

 Pygidium roughly triangular in outline ; its margin with two pairs of well developed 

 lobes, the median pair deeply emarginate on both sides ; the curiously forked 

 squamae beyond the usual prominent tooth-like process seem to be characteristic 

 of the species. 



Lindinger's* examples of the puparia were evidently very much smaller, but the 

 structural details given by him (I.e.) of the adult female agree in all essentials. 

 Quite 50 per cent, of the females were attacked by a parasitic fungus.
