of the female are 7- or S-jointed. The claw is usually without a 

 denticle. The male carries two caudal filaments only. 



Ps. galiani , Green. On Bihes sa)i(iiiiiu)li'nfa, CcanDtlum sp., [.ahiiniiim, 

 and upon sprouting potato tubers. A somewhat troublesome 

 pest in the garden. Adult female purplish grey, thickly 

 coated with white meal. Margin of the body with a fringe 

 of short, white, Avaxy tassels, the four hindermost tassels 

 much longer than the others. 



Ps. hiherniciDi (Newstead). Kecorded, by Prof. Newstead, from "the 

 crowns of various grasses and of the sea-pink {Aniieria vnl- 

 f/aris)." I have taken the species under the loose bark of 

 fallen branches of oak lying on grass in pasture land. The 

 insects had apparently crept into this shelter for the purpose 

 of oviposition and had constructed their ovisacs there. Mature 

 females purplish grey, thinly dusted with mealy powder ; 

 posterior extremity with four short waxy tassels. 



Ps. newsteadi, Green. Under the bud scales and in crevices of the 

 bark of beech trees. Mature female pale brownish ochreous; 

 dorsum thickly and evenly dusted with mealy powder ; 

 abdominal segments with short waxy tassels. 



Ps. pahtdinus, Green. On the foliage of various herbaceous plants. 

 The early adult females weave tent-like shelters in the angles 

 of the more prominent veins on the undersurface of the 

 leaves. Adult female brownish pink, masked by a thin 

 coating of white mealy power. Posterior extremity with four 

 short waxy tassels. 



Ps. pidverariiis (Newstead). Concealed between the leaf-sheath and 

 the flowering stems of various grasses. Mature female 

 narrow and elongate ; pinkish purple ; posterior extremity 

 with one (or two) pairs of short waxy tassels. 



Ps. sphorpii, Green. In nests of the ant Formica picea, and amongst 

 the sphagnum moss surrounding the nests. Adult female 

 pinkish, thinly dusted with mealy secretion. No waxy tassela 

 were observed on the material examined ; but, from the posi- 

 tion and character of the ceriferous organs on the insect, it 

 is probable that fresh examples would exhibit short tassels 

 on the frontal and posterior margins. 



Ps. ivalkeri (Newstead). On various grasses. The insects take up 

 their position on the upper surface of the blades of the grass. 

 At the slightest disturbance they detach themselves and fall 

 to the ground where they quickly creep into shelter. Mature 

 female densely covered with mealy secretion. This species 

 is recognisable by the unusually long and stout waxy pro- 

 cesses, which project forwards from the anterior and back- 

 wards from the posterior extremity. 



I have recently discovered a large species of Vseudococcus that
