PARLATOEIA PERGANDII. 145 



the third and fourth lobes, and those beyond, are 

 deeply fringed and broadly palmate. The plates on 

 the succeeding segments are narrow, and gradually 

 diminish from the deeply fringed to the bluntly dentate 

 or tuberculate form There is a spine at the base of 

 each lobe on the outer margin, and a fifth just beyond. 

 Marginal pores, very large, do not differ in character 

 from those of P. proteus. 



Puparium of the male similar to that of P. proteus. 

 Smoky brown or purplish brown behind the exuviae ; 

 posterior half greyish. Cabinet specimens pale ochre - 

 ous or straw-coloured. Larval exuviae dull yellow or 

 dark orange-yellow, with black or dusky centres. 



Long. 1 mm. 



Prof. Comstock describes the male as purplish in 

 colour, with the disc of the thorax nearly colourless, 

 with the exception of some irregular purplish spots, 

 and the sutures which are brownish ; the eyes are 

 large and very dark. 



Habitat. Exceedingly common on imported oranges 

 in this country, but I have never met with it on culti- 

 vated plants. 



Distribution. A common orange pest throughout 

 the south-west of the United States, in the West 

 Indies, and the Mediterranean area. But Mr. Maskell 

 does not record it from Australia or New Zealand.
