2. Lecanium hemisphmricum, Targioni. 

 Pig. 25. 

 Not unlike the last species to the naked eye, but wanting the keels men- 

 tioned under L. olece. It does not seem to be, as yet, common in this 

 country, but occurs on some garden plants — e.g. Camellia, etc. 

 3. Lecanium mori, Signoret. 

 Fig. 26. 

 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. persiece, Beaumur, where the body is 

 oval and slightly convex, reddish in colour, but without keels. The present 

 insect is about A inch long, smooth, naked, with antennae 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. 



Group.— COCCIDiE; 

 Genus Acanthoeoecus, Signoret. 

 1. Acanthoeoecus multispinus, mihi. 

 (Trans., vol. xi., p. 217.) 

 Occurs near Wellington on Kniyhtia exeelsa and Cyathodes acerosa. 

 Genus Eriococcus, Targioni. 

 1. Eriococcus pallidas, sp. nov. 

 Female enclosed in an elliptical sac of felted secretion, which is yellow- 

 ish white in colour, and about -| 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. 

 Antennas 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), Elccocarpus (hinau), etc. It may be readily recognized by 

 the yellowish- white elliptical felted sac. 



The genera Eriococcus, Rhizococcus, Acanthoeoecus require revision. The 

 present insect resembles E. buxi, Signoret, in its sac, but differs in its paler
