Fig. 25. 
Not unlike the last species to the naked eye, but wanting the keels men- 
tioned under L. olez. It does not seem to be, as yet, common in this 
country, but occurs on some garden plants—e.g. Camellia, etc. 
8. Lecanium mort, rand 
ig. 
An insect which I cannot identify as any but this species occurs on 
Alsophila and other plants in the Botanical Gardens, Wellington. It is 
evidently an introduced insect, and as evidently belongs to the series of 
Lecanium of which the type is L. persice, Réaumur, where the body is 
oval and slightly convex, reddish in colour, but without keels. ‘Che present 
insect is about 4 inch long, smooth, naked, with antenns of seven joints. 
The skin exhibits no tessellations or markings. 
I have not seen the adult male, but there is a white and glassy male 
test.

1. Acanthococcus multispinus, mihi. 
(Trans., vol. xi., p. 217 
Occurs near Wellington on Knightia excelsa and Cyathodes acerosa. 
Genus Eriococcus, Targioni. 
1. Eriococcus pallidus, sp. nov. 
Female enclosed in an elliptical sac of felted secretion, which is yellow- 
ish white in colour, and about 4 inch in length. This sac completely 
envelopes the insect, being closed in at both ends. 
Female insect greenish grey in colour, turning brown after gestation ; 
at first filling the sac, but shrivelling as the sac becomes full of eggs. 
Antenne of six joints, of which the third is twice as long as any other. 
Tibia and tarsus slender; upper digitules fine hairs, lower pair narrow and 
somewhat long. Anal tubercles rather large; anal ring with eight hairs 
(sometimes only six). The body is segmented, but without deep corruga- 
tions, and along the middle of each segment runs a line of conical spines, 
not set very close together and somewhat slender. There are very many 
small oval spinneret orifices all over the dorsal surface. 
Not uncommon throughout the islands on several plants, e.g., Myoporum 
latum (ngaio), Eleocarpus (hinau), etc. It may be readily dcc by 
the yellowish-white elliptical felted sac. 
The genera Eriococcus, Rhizococcus, Acanthococcus require revision. The 
present insect resembles E. buxi, Signoret, in its sac, but differs in its paler
