456 Mr. C. Fuller 07i some species of 



epidermis many raised " figure of eight " spinnerets, and is marked 

 dorsally with many irregular short lines. 



Second stage 9 naked, resting on a thin pad of papery secretion ; 

 almost flat ; the dorsum rising in the centre in the form of a low 

 cone, and marked with radiating lines. Colour slate-black. 

 Antennjp of 8 joints ; basal short and wide, 2 the longest, 3, 4 and 

 5 sub-equal, 6 and 7 sub-equal, 8 short, rounded, and bearing a few 

 hairs. Lobes spined. Anal ring with 10 long flat hairs. Spiracles 

 not prominent, with small adjacent groups of simple pores. $ 

 puparium yellowish-white ; segmented ; elliptical. Length 005 inch. 



On Melaleuca leucodendron (?). Swan River, W. A. 



Genus Asterolecanium, Signoret. 



(Planchonia. p.n. occ.) 



44. Asterolecaniuni lialicie, sp. n. 



Test of adult 9 light transparent green, fiat, circular ; fringe 

 generally absent, lighter than scale ; diameter 0'06 inch. 



Adult 9 almost circular, light green ; flat above, slightly convex 

 beneath. Mentum dimerous. Tubercles fairly distinct, bearing 

 longish setae, and on the inner margin a single spine. Margin with 

 a row of " figure of eight " sjDinnerets, which is occasionally double, 

 but not regularly so as in A. ventro^isa, Maskell. There is also a 

 single row of multiocular pores round the margin. 



(J puparium smaller than test of o, oval, segmented, light 

 green. 



This species is common on the bark of Hakea ilicifolia, 

 and is occasionally found on an Acacia, Swan River, W. A. 

 Like A. ventrousa, the female rests in a small pit, but it 

 does not cause such an abortive growth of the bark as 

 that species, and in general appearance very much resem- 

 bles A. quercicola, a common species in Sydney and 

 Melbourne on oaks. 



45. Asterolecanium petrophil^, sp. n. 



Test of adult 9 A^-t, yellowish-green, circular, sometimes slightly 

 elongate, fringe white. Length 0"045 inch. Owing to the trans- 

 parency of the test it usually appears dark brown or black, due to 

 the colour of the 9 showing through. 



Adult 9 never entirely filling the test. Antennfe represented by 

 a pair of chitinous buttons. Mentum monomerous. Margin with a 

 single row of " figure of eight " spinnerets and a row of simple 

 pores. Dorsum without markings. Ventrum flat.
