130 ROBERT NEWSTEAD. 



The derm cells in these examples from East Africa appear somewhat larger and less 

 oval than I have seen in other specimens from Africa ; possibly due to the age of the 

 individuals. 



Lecanium (Saissetia) cuneiformis, Leon. 

 British East Africa : Mua Hills ; on Acocanthera sp., i. 1914 (T. J. Anderson). 



Lecanium (Saissetia) hemisphaericum, Targ. 



British East Africa: Limosa, ii . 1 9 1 4 (T. J. Anderson). Uganda: Nagunga, 

 on Aristolochia, 20 . ix . 15 ; Entebbe, on Adianium, 10 . ii . 14 — curiously stunted forms, 

 such as are not infrequent on the stems of Adianium ; Mabira, on coffee, 29.vii.13 

 (C. C. Gowdey). 



Lecanium (Coccus) hesperidum, Linn. 



British East Africa : near Mombasa, on banana, i . 1914 ; Mua Hills, on lemon r 

 i.1914 (T. J. Anderson). 



Lecanium (Saissetia) nigrum, Nietn. 



S. India: Coimbatore ; on Lawsonia alba, iv.1910, and on cotton, very heavy 

 infestation, viii.1910 (T. V. R., per E. Ballard). Uganda: Mwera ; on coffee, 

 29.vii.13 (C. C. Gowdey). British East Africa: Government Farm, Kabete; 

 on ornamental shrub, i . 1914 (T. J. Anderson). 



Lecanium (Eulecanium) somereni, Newst. 



Uganda : Nagunga ; on Eryihrina excelsa, 20.ix.15 (C. C. Gowdey). 

 The specimens are of an unusually dark colour and heavily parasitised. 



Lecanium (Eucalymnatus) tessel latum, Sign. 



British Guiana: Botanic Gardens, Georgetown; on Malacca apple, 28.vii.15 

 (R. Ward, per G. E. Bodkin) ; associated with Lecanium wardi, sp. n. 



These examples show a considerable variation in the arrangement of the plates 

 which form the tessellated pattern of the dorsum. Some agree with Signoret"s 

 description (the first I have seen) ; others (two) with the var. perforatum, Newst., 

 though these are not quite typical. 



Lecanium (Coccus) viride, Green. 



British Guiana : Onderneeming, Essequibo, 60; on Liberian coffee, 29.vii.13 

 (G. E. Bodkin). South Africa : 1914 (D. d'Emmerez) ; all immature $$, differing 

 from typical examples of L. viride only in that some have eight instead of seven 

 segments to the antennae. 



Hemilecanium imbricans, Green. 



S. India : Southern Mysore ; on Cedrela tana, heavy infestation, xi . 1903 (2jL 

 Ballard). 



Aspidiotus (Chrysomphalus) aurantii, Mask. 



British East Africa: Kabete; on orange tree, 7 . i . 1 4 (T. J. Anderson). 

 Southern Khodesia : Mt. Chirinda, Melsetter (C. F. M. Synnerton) — very heavily
