INJURIOUS INSECTS AND OTHER I,OWER ANIMAI.S. - GENERAIJTIES I719 



4) A. spini ferns (Quaintance) , on Citrus sp. and on roses at Garalt (Java) 

 and on oranges at ]\Iacao (Southern China) ; 5) Aleurolohus marlatti (Quain- 

 tance), on Citrus sp. and Monts sp. at lyahore ; on Ficus sp. in the Ceylon 

 Botanical Garden ; on oranges at Tokyo and at Kumamoto (Japan), etc. ; 

 on an unknown plant in the Buitenzorg Botanical Garden (Java) ; 6) 

 Aleiirothrixus floccosus (Maskell) common in the following localities : West 

 Indies, Florida, Mexico, British Guiana, Brasil, the Argentine, Chili and 

 Paraguay ; not onl}' seen on the orange (Mexico) and on Citrus deciimana 

 and C. Limetta, but also on the sea grape {Coccoloba uvifera), Pliimeria 

 sp., Baccharis genistelloides, Psidium Gitajava, etc. ; 7) A. howardi (Quain- 

 tance) on the same hosts and in the same localities as A. floccosus ;8) A. 

 forteri n. sp., on the orange at Santia.go, Ransagua, San Bernardo (?) 

 (Chili) ; on Schinus dependens at Santiago ; on S. molle in Chili ; on Lippia 

 citriodora and Myrtus at Santiago ; on an unknown Solanum at Villa del 

 Mar (Chili) and on Eiigenia caidiflora at Rio de Janeiro (Brasil) ; 9) Bemisia 

 gi-ffardi (Kotinsk^-) on Citrus spp. in several gardens in Honolulu (Hawai) 

 where it has probably been introduced, most likely from India, where it 

 has been observed on an unknown ho.st plant at Lahore ; 10) Dialeurodes 

 citri (Ashmead), the so-called Citrus white fly, one of the most harmful 

 pests upon citrus plants in Florida (where it has been known since 1880), 

 and in all the States along the Gulf of INIexico ; recorded also from Colorado, 

 Illinois, the Columbia District and California, and also from Mexico, Chili 

 and Brasil ; without doubt this form is of eastern origin, being found in 

 numerous localities in India, Ceylon, Japan and China ; in Florida it occurs 

 not only on Citrus, but also on Melia Azedarach, Gardenia jasminoides, 

 Ligustrum spp., Diospyros Knki, D. virginiana, Syringa sp., Coijea arabica, 

 Fiats nitida, etc. ; 11) D. citrifolii (Morgan), known in North Carolina, 

 Mississippi, Louisiana, California, Florida, Cuba and Mexico ; besides being 

 found -on Citrus spp. it has also once been recorded upon Ficus nitida at 

 Audubon Park, New Orleans ; 12) Paraleyrodes perseae (Quaintance), 

 known onh" in Florida on oranges, Persea americana (avocado), Persea spp. 

 and perhaps also on persimmons [Diospyros spp.) ; 13) Triahurodes jlori- 

 densis (Quaintance) in Florida on Anona squamosa, Persea americana, 

 Psidium Giiajava and on the orange ; but probably its attacks on the 

 latter are of little importance ; 14) T. vitrinellus (Cockerell) on the orange 

 in Mexico, and on oaks in California ; here again the orange is probably 

 not seriously damaged ; 15) Tetraleurodes mori (Quaintance), a species 

 which is indigenous to the eastern United States and is widely spread 

 throughout them, attacking a great many plant ho.sts : (Mulberrj^-tree, 

 Platanus occidentalis, Acer, Cornus, Celtis occidentalis, Diospyros spp., 

 Ilex, Kalmia, etc.) ; recorded from Arizona and Mexico on oranges, where 

 this parasite is a race rather than a variety of T. mori, to which the name 

 of arizonensis (Cockerell) has been given.
