MasxzLL.—On New Zealand Coccide. 189 
Some of the specimens on Danthonia were more than } inch long, so 
that the insect is quite a large one. 
8. Dactylopius glaucus, mihi. 
(Trans., vol. xi., p. 219.) 
I consider this also a good species, distinct from the last by its green 
colour and small size, which never exceeds +; inch. 
I have obtained one mutilated specimen of a male. As far as I can 
make it out it offers no very distinctive character, except that the abdo- 
minal spike or sheath of the penis seems to be accompanied by a curved 
appendage as in Acanthococcus multispinus, mihi (Trans., vol. xi., pl. viii., 
fig. 18 f). 
Genus Pseudococcus, Westwood. 
A genus separated from Dactylopius by having nine joints in the an- 
tenne of the adult female, and only two digitules on the foot. 
Westwood’s original genus is described as “having females not fixed 
and clothed with a woolly secretion ” (Int. to Mod. Class of Insects, vol. ii., 
appendix, p. 119), characters which, in point of fact, would include the 
whole group Coccide. M. Signoret has confined its limits as above. 
1. Pseudococcus astelia, sp.nov. + 
Figs. 41-44. 
Adult female about +; inch long, yellowish-brown, covered with a not 
very abundant white cotton. General form resembling Dactylopius : the 
body segmented, anal tubercles inconspicuous, anal ring with six hairs. 
Antenne (fig. 41) with nine jgipis, of whieh the third, fourth, and fifth are 
the longest; the second, sixth, and ninth a little shorter ; the first, seventh, 
and eighth the shortest. The fourth, fifth, and sixth are the narrowest, the 
two ends of the antenna being thieker than the middle. The eighth joint 
is a little expanded at the tip; and the ninth is fusiform, with a shallow 
. depression at the extremity. All the joints have a few long hairs, and on 
the eighth is one a good deal stronger than the others. The legs (fig. 42) 
have the tibia twice as long as the tarsus: the claw is slender, and has no 
tooth on the inner edge. There are only two digitules (the lower pair) 
which are long and fine. The trochanter bears one short bristle. The 
whole leg is slender and long. The eyes (fig. 43) are tubercular and 
smooth, showing after maceration in potash a small dark terminal spot. 
The body is covered with a number of spinnerets of two kinds, as shown in 
fig. 44; those with simple concentric circles are the largest, and are 
found all over the integument: the others are placed in groups at the 
edges of the segments and also in great numbers at the cephalic and 
abdominal extremities. Interspersed with these spinnerets are several 
hairs, mostly very short, but on the head are some pretty long. From the
