Habitat. — Australia. 



On Casuarina cquisetifolia. 



Examples of this species have not been studied. It was very 

 imperfectly described by Maskell. The constriction is indi- 

 cated as similar to that of eucalypti, but in the drawing it is 

 shown as not very sharply defined. It was referred to the 

 genus Targionia by Leonardi, but seems rather to belong to 

 Pseudaonidia.

NEW SPECIES OF PSEUDAONIDIA. 

 PSEUDAONIDIA (SELENASPIDUS) LOUNSBURYI, n. sp. 



Female scale. — Scale of adult female flat, subcircular, 2-2.5 m™- i" 

 longest diameter; yellowish white but dense and opaque; exuviae 

 resinous to brown, covered with a very slight excretion; supplement 

 usually three times diameter of second exuvium ; thin but distinct 

 ventral scale present which adheres to the leaf. 



Male scale. — Similar, oval, 1.5 mm. long; exuvium near anterior end, 

 brown. 



Adult female. — Form oval, nearly 1.5 mm. long; strongly chitinized 

 and brown in the case of old spent specimens ; body divided into two 

 subequal parts by a deep cephalothoracic suture; segments of abdomen 

 indicated by distinct sutures but not marked by lateral incisions except 

 in case of anal plate; a short, stout lateral spine, distinctly annulated 

 in the more hardened specimens, a little anterior to cephalothoracic 

 suture. 



Anal plate. — Similar in general characteristics to articulatus but ex- 

 hibiting important differences; lobes in three pairs, not very large, oval
