Maskell. — On Coccididse. 25 



visible, setiferous, very small. Antennse of six subequai 

 joints : feet normal. On the margin is a row of jBigure-of-S 

 spinnerets, from which spring curling, white, glassy tubes. 



Adult male very small, yellow : length about Jjyin. The 

 thorax is rather thick, the abdomen tapering to the spike, 

 which is slightly curved, and about as long as the abdomen. 

 AntennaB of ten joints, of which the first two are short and 

 thick, the rest long, slender, and hairy : on the last joint are 

 four knobbed hairs. Dorsal eyes, four ; ventral eyes, two : 

 ocelli, two. Wings delicate, iridescent. 



Hab. In Australia, on Stijplidia ricliel and Leptospermicm 

 juniperinum : specimens from Mr. French. 



This insect is closely aUied to the New Zealand species P. 

 epacridis, and it is noticeable that both affect plants of the Epac- 

 rid order — Styphelia and Lcucopogon. The differences between 

 them are microscopic; perhaps the most noticeable is the 

 extreme smallness of the anal tubercles in the Austrahau 

 species. But the dark thougli translucent test of P. epacridis 

 is not Hkely to be mistaken for that of P. stijphdice. The 

 male just described is the only one yet observed in the genus : 

 it does not seem to present any very peculiar characters, but 

 is remarkable for its extremely small size.
