MaskELL.—On some Coccide in New Zealand. 205 
My subsections of this group, after having said so much of its general 
characteristics, are as follows :— 
1, Lecaniee, for the species having the body of the female naked, 
often viviparous. 
2. Pulvinariee, for the species having the body naked, but formimg 
cottony nests for the eggs 
8. Lecanio-diaspide, for the species having the body covered with a 
test ; sometimes viviparous. 
Of course, Tam here only paying attention to such classes as contain 
genera known to me in New Zealand. There are many other divisions, but 
they do not come within my scope. 
Subsection I.—Lzcanmz. 
All the species which I have observed in this class are European, and I 
might therefore, according to my intention expressed just now, pass them 
over without entering into details. But there is one species which has 
become so widely spread and so noxious in this country, and which is 
moreover so excellent a type of the whole group, that I am constrained to 
dwell more particularly upon it. This species, which infests in our green- 
houses a vast number of plants, and in our gardens the holly, ivy, ilex, bay, 
Portugal laurel, orange and other trees, is, I suppose, tolerably well known, 
as far as its outside appearance goes, to most amongst us. It is 
1. Lecanium hesperidum; auctorum. 
Plate VI., fig. 12. 
The young insect, in outline, is not much different from that of Mytilas- 
pis pomorum, with the exception of the abdominal cleft. In colour it is 
reddish brown; it is flat and very active. The antenns have six joints, 
but the fifth joint looks as if it were composed of two soldered together; the 
third joint is the longest. The last joint has a few hairs. The tibie and 
tarsi are of about equal length; the upper pair of hairs, or digitules, above 
the claw long, the lower pair short and narrow. The abdominal lobes end 
in two very long sete. Plate VI., fig. 12a. 
The adult female is figured by Westwood (vol. 2), but not large enough 
for detail. M. Signoret gives only a brief — The insect is flat, 
oval, brown in colour, sometimes as much as } inch long. The abdominal 
lobes are not, in the live animal, so apparent as in the young; but when 
mounted for the microscope they are plainly seen to be without the two 
long hairs characterising the young insect; as shown in plate VI., fig. 11b. 
The anal ring is surrounded by six long hairs. The lobes are triangular, 
with rounded angles, or heart-shaped. 
The antenns, which do not, as in the Diaspide, disappear with age, — 
have seven joints; fig. 12b. The first and second joints are the thickest;
