196 E. E. GREEN. — NOTES ON COCCIDAE. 



positions. Circumgenital glands in five groups : median group with from 3 to 5 

 pores (usual number 4), upper laterals 6 to 9 (average 8), lower laterals 7 to 9 

 (averages). Length averaging 1*25 mm. 



On leaf stalks of Coconut Palm. Silhouette, Seychelles, 



The species is characterized by the exceptionally large inner lobule of the duplex 

 lateral lobes, which equals the median lobes in size. I am not sure if the depression of 

 the female puparium is a normal character, or whether it has been caused by 

 pressure between adjacent leaf stalks. It was noticeable that the flattened examples 

 were grouped at the lower end of the stalk. 



Since the publication (in Trans. Linn. Soc. Lond., xii, part 2, p. 197, 1907) of a 

 list of CocciDAE occurring in the Seychelles, the following species have been identified 

 in collections received from Mr. Dupont :— 



Lecanium mangiferae. Green : on Cinnamon and imported Mango plants. 



Aspidiotus dictyos'permi pinmdifera, Mask. : on Jasminum, Thunbergia, Pandanus 

 and Coconut. 

 Aspidiotus bro7neliae, Newst. : on Pine-apple plants. 

 Aspidiotus ansei, Green : on Cocos nucifera. 

 Ischnaspis filifonnis, Dougl. : on Oil Palm. 

 Gymnaspis grandis, Green : on Lodoicea (Coco de Mer). 

 Parlatoria pergandei, Comst. : on Thunbergia. 

 Lspidosaphes duponti, Green : on Cocos nucifera. 



The list of species recorded from these islands is still a very small one, and the 

 number of genera represented is extraordinarily poor. It includes I eery a (1 sp.), 

 Asterolecaniufn (2), Pseudoeoccus (2), Pulvinaria (2), Ceroplastes (1), Vinsonia (1), 

 Lecanium (7), Chionaspis (1), Hemichionaspis (2), Diaspis (1), Aspidiotus (8), Lepi- 

 dosaphes (4), Ischnaspis (1), Gymnaspis (1) and Parlatoria (!) ; a total of 15 genera 

 and 35 species only. Such widely distributed genera as Orthezia, Antonina, Erio- 

 coccus and Fiorinia, are as yet unrepresented.
