Eggs. — Clutch 2 ; oval in shape, slightly more compressed at 

 the smaller end ; texture of shell fine ; surface glossy ; colour 

 whitish or pinkish-white, finely but distinctly spotted with reddish- 

 brown and purplish-brown, the markings, which are moderately 

 disposed, being, of course, thickest on the larger end. Most 

 resemble the eggs of its near ally, P. penicillata. Dimensions in 

 inches — (i) .85 x .6 ; (2) .83 x .6.

Ctenochiton cellulosus, Ckll., n, sp. 

 Waxy scale, 4mm. long, 2 broad, i^^ high; white, with a very 

 faint yellowish tinge ; regularly rounded and without keels ; not 

 at all divided into plates, but very rough — in fact, tuberculate all 

 over — and everywhere dotted with air-cells, which are easily 

 visible with a lens. These air-cells are quite irregularly placed 

 (not in rows), and are irregular in form, from 30 n to 60 ^ 

 diameter. No true fringe, but the scale viewed from above 

 seems to have a short irregular fringe, owing to the lateral 

 tubercles projecting. 



Female insect reddish-brown, shrivelHng to one end of the 

 scale. Margin with a row of short-pointed spines, broad at base, 

 about i2/i long, and very close together. Mouth-parts very 

 small. Anal plates rather irregularly formed, and bearing several 

 stout bristles. Anal ring with six large bristles. 



Femur with trochanter, 150^1* long; tibia, 117; tarsus, 75; 

 claw, 24 }i, bulbous at base, with a curved tip. Tarsal digitules, 

 60 fi. 



Antennae slender, eight-segmented, the segments measuring 

 thus in /x:— (i) 42, (2) 3c. (3) 57, (4) 51, (5) 34, (6) 18, (7) 18, 

 (8) 34. Formula 341 (58) 2 (67). 



Hab. — Myrniong, Victoria, on Melaleuca nodosa. Collected 

 by Mr. J. Lidgett (No. 23). A very distinct species. 

 Rhizococcus lidgetti, Ckll., n. sp. 



Female insects on twigs, very dark purple, naked even when 

 full of young. Boiled in caustic soda, they give a very fine 

 magenta colour ; the female boiled and flattened under a cover 

 glass is 4 mm. long and 25^ broad. Mouth-parts very small. 

 Legs and antennae very pale. Dermal spines numerous, about 

 30 n long. 



Femur with trochanter, 105^1 long; tibia, 78; tarsus, 90; 

 claw, 24 ^, not much curved. 



Antennae seven-segmented, segments measuring in fA. : — (i) 36, 

 (2j 30> (3) 42, (4) 27, (5) 18, (6) 16, (7) 27. Formula 312
