174 MISCELLANEOUS PAPERS. 



As will be noted, specimens of this species have been received at 

 different times since 1880. The material from Crescent City, Fla., 

 was collected by Prof. H. G. Hubbard, and labeled by him as citri. 

 In fact, all of the Hubbard specimens in the Bureau collection are 

 nubifera^ and it thus seems possible that Mr, Hubbard did not see 

 the true Aleyrodes citri at all. 



The material from Cuba, collected by Mr. C. L. Marlatt, and also 

 sent in by Dr, Mel T. Cook, and provisionally referred by the writer 

 to citri, belongs, in fact, to nuhiferd, and our record of citri for Cuba 

 is incorrect. So far as Ave are aware, the insect does not occur on 

 the island at all. As to the origin of nuhifera and the time of its 

 introduction, if from abroad, we have no information. Its affinities 

 are with Oriental species, and it is not improbable that it was intro- 

 duced into Florida along with or about the time of the introduction 

 of citri. 



Recently additional information has been obtained relative to the 

 occurrence of Aleyrodes citri in eastern Asia. The writer, at a meet- 

 ing of the Washington Entomological Society, October 4, 1908, ex- 

 hibited a specimen of Aleyrodes citri from Canton, China, on orange, 

 Avhich had been found in the Bureau collection, Avithout other data. 

 In June, 1008, specimens of lemon leaA^es from Peking, China, infested 

 wdth an aleyrodid were received by the Bureau from Mr. F. N. 

 Meyer. Eggs, puj^a, and one adult were present, and Avith this series 

 of stages it Avas possible to definitely determine the insect as citri. In 

 July of the same A'ear leaA^es of Gardenia from Japan, also infested 

 Avith Aleyrodes citri, Avere receiA^ed through ]Mr. E. M. Ehrhorn, and 

 someAvhat later, in 1908, six lots of material, all infested with 

 Aleyrodes citri, Avere receiA^ed through Mr. E. H. Carnes, four of 

 the sendings being from Nagasaki, Japan, and two from Shanghai, 

 China. Four lots were on orange, one on a citrus plant, and one 

 on an unnamed plant — possibly a Viburnum. The material from 

 Nagasaki had been collected in 1903 ; the balance in 1908. 



In Maskell's collection of Aleyrodidse, recently secured with his 

 coccid collection by Doctor Howard from the New Zealand Institute, 

 Avas found AAdiat is evidentlv the type slide of Maskell's Aleyrodes 

 aurantii, originally described in the New Zealand Transactions (1896), 

 page 431, as a variety of engenia'. Careful comparison of this insect 

 Avith Aleyrodes citri proA^es it to be the same species, and Maskell's 

 name hence becomes a synonym of citri Riley and HoAvard. Maskell's 

 ■ material was from the northwestern Himalayas in India, on Citrus 

 aurantinm. The great similarity of eugenice to citri Avas noted by 

 Mr, Maskell, but he attributed undue importance to the presence of 

 the three radiating patches, Avhich, while occurring in citri, Avere not 

 mentioned in the descrij^tion by Riley and HoAvard.
