THE VICTORIAN NATURALIST. 15 



Adult female after boiling transparent ; five groups of circum- 

 genital glands, median of 7 to 8, anterior laterals 15 to 16, 

 posterior laterals 14 to 16, the anterior lateral group often 

 elongated; very many dorsal glands of the type of those of 

 Parlatoria zizyplius, but shorter ; four pairs of lobes ; median 

 lobes fairly large but short, truncate, shaped like the end of an 

 axe-blade, broader than long, separated by a rather wide interval, 

 but the margin not depressed between them. At the outer side 

 of each median lobe is a long spine, nearly twice as long as the 

 lobe, then comes a very short pointed squame ; next, and 

 separated by a wide interval from the median lobe, comes the 

 second lobe, which is divided into two separate lobules, the first 

 large and rounded, the second also rounded, but smaller and 

 narrower ; at the second lobule of the second lobe is another long 

 spine, then a pointed squame, bifurcate at the end ; then after an 

 interval comes the third lobe, completely divided into two 

 separate rather small lobules ; then a long spine and a pointed 

 squame, then a more or less rudimentary fourth lobe, the lobules 

 of which are bluntly pointed. 



Hah. — Massed on bark of Eucalyptus rostrata, Schlecht, and 

 E. goniocalyx, F. v. Muell., Myrniong, Victoria, Australia 

 (James Lidgett). 



The female scales of M. lidgetti are exactly like those of 

 M. casuarinas, which I have from Mr. Maskell. The female of 

 casuarince, however, is very easily known from lidgetti by the 

 depression between the median lobes, which are broad, little 

 produced, and strongly crenulate. 



2. — A New Pulvinaria. 

 Pulvinaria paradelpha, Ckll. and Lidgett, n, sp. 



Female (shrivelled) about 4 millim. long, oval, rather pale brown. 

 Ovisac white, broad and flat, of rather a leathery consistency, 

 nearly parallel-sided, about 10 millim. long, and 4 broad. Margin 

 of female almost spineless, the spines few and minute. Spines of 

 lateral incisions in threes, the middle one about twice as long as 

 the others, all of about equal thickness throughout, not bulbous 

 or clubbed at end as in P. thompsoni. Skin with fairly numerous 

 round glands, some large, others small. Antennae 8-segmented, 3 

 longest, and longer than 4 and 5 together. Formula 3 (281) (45) 

 (67). Legs fairly stout, tarsus about two-thirds length of tibia ; 

 claw short and strongly hooked ; tarsal digitules slender ; claw 

 digitules gready expanded, with very broad ends. Mouth parts 

 small. 



Male scale glassy, translucent, with a flat dorsal area crossed by 

 two or three sutures ; and seven or eight sutures on each side, 

 runnii g from the sides of the dorsal area to the margin.
