is much smaller, averaging only 4i, inch in length. I do not quite see, 
also, why L. hesperidum, which is free from fungus in our gardens, should 
be so subject to it in the forests; indeed, almost exclusively so, for few 
other insects suffer in the same way. Fiorinia astelie is sometimes found 
in the same state, and I have specimens of an Alewrodes from Pelorus 
Sound also attacked by fungus; but this little Lecanium seems to be the 
chief victim. 
Subsection III.—LeEcANIO-cocoma. +. 
The species forming this subsection are all European, and I how not 
seen any in New Zealand. 
8rd Group.—HEMI-COCCIDA. 
I have not seen a true Kermes in New Zealand, but have received from 
South Australia an insect of this genus which deserves full examination. 
The genus Asterolecanium, which I have placed under this group in my 
foregoing list of genera, is to the naked eye similar to Planchonia, and it 
requires an examination of the abdominal region in all stages to detect the 
difference. But M. Signoret distinctly states that the adult Asterolecanium 
has the abdomen of the Lecanide. 
4th Group.—COCCIDA. 
Charaeterized by the absence in all stages of the deep abdominal 
cleft, and by the prolongation of the abdomen into lateral processes, more 
or less conspicuous, which I have called in these papers ** anal tubercles.” 
In some genera, as Dactylopius, these tubereles are scarcely noticeable, but 
may usually be made out on close examination (see Trans., vol. xi., pl. viii., 
figs. 19d and 199). In others, as Icerya, there is so much secretion and 
hair on the abdomen of the adult that the tubercles can scarcely be 
detected. But in no case, I think, can any of the species be mistaken for 
Lecanide. 
As for the mentum, it is usually tri-merous; but this character is varia- 
able, and also most difficult to make out. 
Genus Planchonia, Signoret. 
1. Planchonia epacridis, mihi. 
(Trans., vol. xiv., p. 224.) 
I think this species may stand. As remarked above, it outwardly 
resembles Asterolecanium. 
Genus Eriococcus, Vergini; 
Eriococcus araucarie, mihi. 
(Trans., vol, xi., p. 218.) 
This appears to be certainly distinct. M. Signoret informs me that he 
has lately received some specimens from Spain. Mr. Comstock reports it 
also from the United States, but refers it to the next genus Rhizococcus,
