SCALE-INSECTS. 55 



Male puparium white, elongated, rather oval ; very slightly 

 carinated above; on the under-side are two longitudinal keels. 



Adult female yellow, elongated, segmented ; the abdominal 

 segments somewhat deep. Abdomen ending with a median 

 depression ; terminal lobes inconspicuous (absent ?) . Five groups 

 of spinnerets : uppermost group, six to ten orifices ; the rest, 

 ten to fifteen. 



Adult male reddish in colour. Antennae hairy, 10-jointed, 

 the first two joints very short. Feet normal, with four long, 

 fine digitules. At the base of the abdominal spike is a some- 

 what large tubercle. Haltere of normal form, but the terminal 

 seta is very long, four times as long as the thick basal portion, 

 and has no terminal knob. Thoracic band conspicuous. The 

 thorax is somewhat long, so that there is a considerable distance 

 between the first and second pairs of legs. 



Habitat On Coprosma, Rubus, Asplenium, Pell&a, Pticcarton 

 Bush and North Kowai River, Canterbury; Auckland. 



The female puparium resembles that of C. aspidistra 

 (Signoret) and C. populi (Barensprung), but the abdominal seg- 

 ment of the female differs from both.

 (Plate VI., Fig. 3.) 



Female puparium thin, flattish, pyriform, white in colour, 

 with a faint pink tinge when the egg-mass beneath shows 

 through it ; length, about j^in. The second pellicle is com- 

 paratively large. 



Male puparium white, narrow, carinated ; length, about yj^in. 



The insect affects principally the leaves of the plant, and the 

 puparia are usually clustered thickly along the midrib. 



Adult female yellowish-red, elongated, segmented ; but not 

 very deeply. Abdomen ending in a broken curve, with many 

 curvilinear incisions. There are fourteen lobes, of which the 

 two median are the largest ; separated from them by a spine on 

 each side are two others rather smaller ; then another spine and 

 a short open space ; and then three smaller lobes and another 

 spine ; another space, and then a single small lobe, followed by a 

 spine. Five groups of spinnerets : lower pair with twelve to 

 fourteen orifices ; upper pair with seven to ten ; uppermost group, 

 four to six. A few spiny hairs are on the edge of the abdomen.
