median division, though the lobes are closely approximated. Leonardi (" Saggio di 

 Sistematica delle Fioriniae ") figures a form that is nearer to my figure a. Fuller 

 (" Notes and Descriptions of some Species of Western Australian Coccidae ") 

 describes — as F. acaciae var. hihha — a form with "two lobes, closely adjacent and 

 at first sight appearing as one semi-circular lobe." In some examples the lobes are 

 widely divergent (see fig. 9, c). In others {g) they are small and almost obsolescent.

Asterolecanium hilli, sp. nov. 



Puparium of female yellow. Elongate, slightly convex above, bluntly pointed at 

 posterior extremity, with a slight median longitudinal carina which is obsolescent 

 in some examples. Marginal fringe short and inconspicuous, often fragmentary. 

 Average length 2 mm. Breadth 0-75 mm. 



Fig. 10. Asterolecanium hilli, sp. n. ; a, adxilt female, X 80 ; b, posterior 

 extremity, X 280 ; c, marginal pores, X 500. 



Adult female at first elongate, the posterior extremity bluntly pointed ; 

 afterwards the body becomes greatlv contracted and transversely wrinkled across 

 the base of the abdomen (fig. 10, a). Frons strongly produced in front of the rostrum, 

 which, in the later stages, assumes a central position, the rudimentary antennae 

 remaining near the anterior extremity. Spiracles placed close to the margin.
