Genus Eriococcus. 

 Eriococcus araucariae, Mask., var. minor, var. nov. 



Sac of female elongate-elliptical, snowy-white, of very loose 

 cottony texture ; length about ^in. 



Sac of male of similar colour and form, but smaller and 

 more closely woven ; length about ^yin. 



Adult female brown or yellowish-brown. Normal form 

 elliptical, but shrivelling at gestation. Length about ^in. 

 Antennae of six subequal joints as in type. Feet, anal ring, 

 and anal tubercles as in type. Marginal spines rather 

 shorter and stronger than in the type. 



Adult male unkown. 



Hab. In Australia, on Kunzea sp. Mr. Froggatt sent me 

 specimens from Manly, New South Wales. 



I can detect no character, except size, valid for separation 

 of this form from the type which I reported, in 1878, from 

 Norfolk Island. 



Eriococcus multispinus, var. laevigatus Maskell. N.Z. 

 Trans., 1890, p. 20. 



Mr. Froggatt has sent me specimens of this insect from 

 Oatley, near Sydney, on Epacris longifolia. The species is 

 readily distinguishable on account of the various numerous 

 short, blunt, conical spines scattered on the dorsum. 



Eriococcus pallidus, Maskell. 1884. 



I have received from Mr. T. Kirk, F.L.S., some specimens 

 on Metrosideros robusta (locality not stated) in New Zealand, 

 which on examination prove to have the slender spines and 

 the elongated third joint of the antennae which characterize 

 this species. The marginal spines are normal, but those on 

 the dorsum are scanty and small; and the cottony sac is 

 rather dark-coloured. This form seems therefore to approach 

 the variety on Fagus menziesii (the last of the four mentioned 

 in my paper of 1890, p. 21). 



I find that I have not, in any of my papers, described the 

 larva of this species, and therefore do so now. This stage 

 does not appear to differ appreciably in the different varieties. 

 The larva is pale-red in colour, the form normal of the genus ; 

 length about gV 11 - The antennae have six subequal joints, of 

 which the fourth and fifth are rather the shortest. Feet rather 

 thick ; digitules fine hairs. Anal tubercles short, setiferous. 

 The margin of the body bears a row of rather strong spines. 



The colours of the adult females vary somewhat in the 

 different varieties. The type form is greenish-grey, turning to 

 brown at gestation : others are brown or red.
