Maskell. — On Coccidae. 301 



short spine with a tubercular base. Four groups of spin- 

 nerets, each with 6 to 10 orifices. 



Larva subglobular, dark - brown ; length, about x^oin. 

 Abdomen terminated by a minutely - serrated margin, on 

 which are four small subcylindrical lobes. 



Male pupa dark-red, elliptical ; length, about -^^in. The 

 abdominal margin exhibits six lobes and a fringe of broad 

 scaly hairs as in the female. 



The female puparium when overturned is seen to have two 

 longitudinal keels, which form a deepish groove in which the 

 insect lies. 



Hah. In China, on Myrtus, at Amoy, and on Camellia, at 

 Macao: the latter are somewhat smaller than the former. 

 My specimens are from Mr. Koebele. 



All the species of Parlatoria, with the exception of P. 

 zizyphi and P. 'perpusilla, are difficult to difierentiate. The 

 colours of the puparium vary somewhat, and the present 

 form, by its greenness, approaches rather to P. myrtaSf 

 Mask., 1890, than to P. proteus, in which the puparium is 

 light-brownish-yellow ; and in the smallness of the pellicles it 

 also resembles P. myrths. But I have preferred to attach it 

 to P. proteus, on account of the small spine on the margin 

 beyond the lobes, which entirely agrees with my specimen of 

 that species, and also with a figure of it given by Comstock 

 (2nd Cornell Eeport, 1883, plate iv., fig. 3). This spine is 

 wanting in P. myrtus and also in P. pittospori, Mask., 1890, 

 and it is replaced by a small lobe in P. pergandei, Comst., 

 1880. 



It is possible that at a future time P. proteus may be taken 

 as a type, as follows : — 



P. proteus, Curtis, 1843. 



„ var. pergandei, Comstock, 1880. 



„ „ sub-var. camellia}, Comst., 1883. 



„ var. rmjrtus, Maskell, 1890. 



„ var. pittospori, Maskell, 1890. 



„ var. virescens, Maskell, 1896. 



Parlatoria zizyphi, Lucas. 



I have received specimens of this species during the year 

 from Hongkong, on oranges, sent by Mr. Koebele. Evidently 

 the insect is being rapidly spread over the world now by the 

 extension of the fruit trade. 



In connection with this point the following circumstance 

 may be interesting, and also amusing, at least to economic 

 entomologists. In my paper of 1895 I reported that P. zizyphi 

 was found in Western Australia on oranges and lemons im- 

 ported there from Sicily. The fruit sent to me by Mr. Lea was 

 very thickly covered with insects — indeed, dangerously so ;
