Maskell. — On New Zealand Coccidas. 139 



Some of the specimens on Danthonia were more than J inch long, so 

 that the insect is quite a large one. 



3. Dactylopius glaucus, mihi. 

 (Trans., vol. si., 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., pi. viii., 

 %. 18/). 



Genus Pseudococeus, Westwood. 



A genus separated from Dactylopius by having nine joints in the an- 

 tenna 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 Coccidce. M. Signoret has confined its limits as above. 



1. Pseudococeus astelice, 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. 

 Antennas (fig. 41) with nine joints, of which 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 thicker 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
