which distinguish it from the next genus which has but two or three rows, 
and from the European species which has six. Besides these there are a 
number of spinnerets secreting the cottony meal, and many of these protrude 
as tubes of peculiar shape, as shown in fig. 184. The antennze, fig. 18e, have 
six joints, the third the longest, the fourth and fifth equal to each other and 
nearly round. The legs have the tibia somewhat shorter than the tarsus, 
the upper digitules are pretty long, the lower only short hairs. 
The male insect is orange red, with long wings, undergoing its trans- 
formations in a sac resembling that of the female. The antenne have ten 
joints, of which the fourth, fifth, sixth, and seventh are long ; the second, 
third, eighth, and ninth wider and globular; the tenth globular but smaller. 
The hook of the foot is long; the abdominal spike, fig. 18/, is short and 
thick, with a curved appendage. 
i II.—Enrococcvs, Targioni. 
This subdivision also has a sac, but it is usually less elongated than in 
the last, and white in colour. My species, to which I give the name of 
Eriococcus araucarie, sp. nov. (?) 
is found on the Norfolk Island pine at Governor's Bay, but I am by no 
means certain that it is indigenous. The female insect differs from the last 
described only in the number of the conical spines, of which there is usually 
only one row round the edge, though in some specimens a few seattered 
spines may be seen elsewhere. It appears to resemble greatly E. buzi, 
Signoret, and I doubt whether it is a new species; at the same time, the 
anal hairs are only six in number as against eight in E. buzi, and the lower 
digitules appear to be much smaller. I therefore provisionally consider it 
a distinct species. 
I have a specimen of the male, not in its perfect state but as a pupa 
upon the point of undergoing transformation. It appears to differ some- 
what from that of Acanthococcus, but I am unable to say how far it differs 
from E. buzi. 
III.—DaoryLorius, Signoret. 
The females of this subdivision have eight-jointed antennz, the anal 
tubercles less prominent than in the two foregoing, and usually a series of 
cottony appendages running all round the edge ef the body, increasing in 
length at the posterior end. 
The differences between my species and those described in Europe are 
not, in some cases, great, yet they are such as induce me to set down my 
New Zealand specimens as distinct species. 
Dactylopius calceolaria, sp. nov. (?) 
Plate VIII, fig. 19. 
This insect is effecting great destruction in the publie gardens in Christ- 
church amongst the calceolarias, and upon several native plants such as
