ou account of the short blunt conical form of the very 

 numerous dorsal spines and the short antennae with sis sub- 

 equal joints, characters distiuguisliing E. multispimis from 

 E. pallidus, in which the spines are slender and the third 

 antennal joint long, a,nd from E. raithbyi, which has no dorsal 

 spines, and seven-jointed antennae.

This species exliibits several variations in the arrange- 

 ment of the dorsal spines, and shghtly in the size and colour 

 of the sac. 



Ou Elczocari)us dentatus the type-form occm-s, in which 

 the sac is large (about lin.) and light -coloured, and the 

 dorsal spines are arranged in a single transverse row ou each 

 segment. On 2Iyoporum Icetum the sac is also large and 

 light, the spines being usually as in the type, but frequently 

 almost wanting ou the abdominal segments. On AthcrospernuL 

 novcB-zealandice and on Fagus menziesii the sac is smaller 

 (about xV"^-) ^^^ dark-coloured ; the enclosed insect is also 

 rather dark, and the dorsal spines are more numerous than in 

 the t}-pe, each segment exhibiting several scattered spines. 

 On Fag us menziesii, again, occurs another variety with a small, 

 dark, ratlier solid sac ; the dorsal spines being less numerous 

 than in the last form, and more approaching to longitudinal 

 rows on the abdomen. 



I leave all these as variations of one species chiefly on 

 account of the antenna, which I find similar in all, with six 

 joints, of which five are sub-equal, but the third joint is 

 longer, usually equal to any two of the others. This 

 character, together with the slenderness of the spines, 

 distinguishes E. pallidus from E. mulfispinus, irrespective of 

 the variations in the sac, which are not indeed so important. 



The varieties here mentioned occur at Wellington and 

 Reef ton. Doubtless forras neai'ly similar may be found else- 

 where and on other trees. 



Eriococcus danthonise, sp. nov. Plate Y., figs. 12-17. 



Sac of adult female pure-white in colom-, very loose in 

 texture ; form elliptical ; length about 3^in. 



Sac of male pure-white, similar to that of the female, but 

 smaller ; length about ^in. 



Larva brownish-yellow ; elongated, flattish, active, naked ; 

 length about ^in. Antennae short, thick, of six sub-equal 

 joints ; the last joint bears some longish hairs, one a good 

 deal longer than the others. Feet rather thick ; all the 

 digitules are fine hairs. Anal tubercles large and prominent.
