Sac of adult female white, elongated, cottony, often in masses. Length, 

 jV of an inch. Adult female elongate oval, convex, distinctly segnientecl; 

 and of a -yellow colour with the anal tubercles brown. Autennse with six 

 joints. Feet normal. Anal ring small, with eight hairs. Anal tubercles 

 short, blunt, angulate on'the sides with three stoui spines on tlie outer margin, 

 a slender one, on the inner, and a fine seta at the tij). Derm with a marginal 

 fringe of stout, rather blunt spines, dorsum not showing any other spines or 

 spinnerets in any imniber. 



Maskell described the type very briefly, and his figures give very little 

 detail. This is amended in his " Coccidse of New Zealand,"' but the figure 

 of the anal tubercles is not correct. Comstock's first report adds very little 

 and his figure of the anal segment is worse. I have not been able to consult 

 Comstock's second report. Maskell described a variety obtained at Manly, 

 New South Wales, u])on K'oizta capitata as E. araucaricp, var. minor, of 

 which he says, " Length about -/(, of an inch ; antennae, six subequal joints 

 as in type; feet, anal ring, and anal tubercles as in ty])e ; marginal spines 

 rather shorter and stronger than in type." 



The foodi)lants bi both are always thickly covered with black smut through 

 the presence of the coccids.

En'orocois husan'fP, n.sp. (Fig. 52). 

 - This fi:;^ speciejs comes from Nimitybelle, New South Wales, upon the 

 twigs and foliage of the "■ Native Blackthorn " {Bi(saiia spinosa). 



Sac of a^ilt female broadly oval, rounded at the extremities, and fitting 

 close against. the bark: the anal oi)ening in a slight depression well up from 

 the edge. Length, | of an inch. Composed of closely -felted fibres with a 

 slight transverse structure; the surface roughened with fine downy hairs, 

 like a bit of tweed cloth. Colour bright -buff or reddish-brown. Clustering" 

 together, they are somewhat irregular in form. 



Adult female ochreous yellow, broadly oval; about -r^ of an inch in length. 

 Antenna' com})osed of eight rather long joints, the first short, broad ; second 

 broad, third longest, fourth and fifth smaller, sixth and seventh rounded on 

 the sides, eighth long roundetl at tip, hairy. Legs long, tarsus about the same 

 length as the tibia ; claw short ; digitules long hairs. Anal ring with eight 

 hairs. Anal tubercles very short, very broad at the base, with two deep 

 curves on the inner margin, so that the upper ])ortion is narrow and roundedi 

 with a terminal seta on either edge. The whole of the epidermis covered 

 with scattered short yellow conical thorn-like sjjines, and thickly clothed 

 with fine hairs. 



This species comes in the Eriococcim eucalypti grou]). but is a much larger 

 coccid, with the spines A\adely scattered, longer eight-jointed antennae and 

 distinctive anal tubercles.
