On the margins a row of strong conical spines, usually bearing 

 tubular cottony fila.ments. On the dorsum a median longi- 

 tudinal double row of conical spines, much smaller than those 

 at the margin. 



Adult female dull brownish-yellow, or sometimes dull- 

 pink : elongated; segmented; length averaging about j^jin., 

 width about xtji^' ^^^ insect being thus rather imusually long 

 and slender. Antennae of seven sub-equal joints, the last 

 bearing numerous hairs. The feet, as usual in the genus, 

 have the tarsus longer than the tibia ; all the digitules are 

 fine hairs, the lower pair rather long. Anal tubercles con- 

 spicuous ; anogenital ring with eight hairs. Mai-gins bearing 

 a row of strong conical spines, three on each side, on each 

 segment ; from these spring usually cottony filaments. On 

 the dorsum a large number of simple circular spinneret-orifices^ 

 and several very slender spines. 



Adult male pinkish or light-red, the dorsal part of the 

 thorax yellowish; length of body about ^in. Abdomen 

 rather slender ; spike short ; terminal segment bearing on 

 each side two longish setae, from which spring the usual long 

 cottony '-'tails.'' Antennae of ten joints, the third much 

 the longest and somewhat dilated at its tip ; all the joints, 

 especially the last three, are hairy. Dorsal eyes, two ; ventral 

 eyes, two-: ocelli, two. The wings are perhaps rather more 

 sohd than usual. 



Hah. On Danthonia ciinninghamii, Eeefton district, New 

 Zealand, fiequently clustered thickly between the culms and 

 sheathing- leaves of the grass. 



The snow-white, loosely-constructed sac and the elongated 

 slender form of the female in this species readily distinguish 

 it. The seven-jointed antenna is abnormal, but I have al- 

 ready, in the case of E. raithbyi (Trans., vol. xxii., p. 146), said 

 that I do not consider this point, taken by itself, as sufficient 

 to remove an insect from the genus. There is no species in- 

 digenous to this country which can be mistaken for it, and it is^ 

 not at all hkely to have been introduced.

In my description of this insect I mentioned as its food- 

 plant Pi'ttosporum unchdatum. Mr. French has sent me from 

 Melbourne specimens on Eucalyptus goniocahjx : these speci- 

 mens are larger than those which I received from South 

 Australia.
