Female puparium at first round, with central pellicles {^fig. 3) ; afterwards 

 usually oblong, with pellicles situated towards the anterior extremity {figs. 4 

 and 6), often distorted by crowding ; strongly convex above, the apex some- 

 times curving forwards until the pellicles assume a nearly vertical position 

 {fig. 5) ; surface more or less roughened by the admixture of small fibres and 

 hairs from the plant upon which it is fixed, the texture consequently varying 

 with that of the plant. Ventral scale well developed, usually entire. Colour 

 greyish ochreous or brownish ochreous, margin whitish, semi-opaque ; pellicles 

 castaneous brown, more or less obscured by layers of whitish secretion, usually 

 with a white central boss surrounded by a prominent whitish ring {figs. 2, 3, 4) ; 

 position and form of peUicles best seen from inner side {fig. 6). The develop- 

 ment of the puparium can be followed by reference to figs, i to 4 in sequence. 

 Size I5 to 2 mm. by i mm. 



Male puparium unknown. 



Adult female bright yellow or orange yellow ; no indication of eye-spots. 

 Body broadly oval, slightly tapering and pointed behind ; abdominal segments 

 distinct before gestation {figs. 13 and 14), afterwards the median area becomes 

 more strongly convex and the segments inconspicuous, and there is usually a 

 large shallow depression above the cephalic area {fig. 12). Antennas rudi- 

 mentary, consisting of a pair of small tubercles, each with a longish curved hair 

 on one side and surmounted by several (four or more) short-pointed processes 

 {fig. 17). No parastigmatic glands. Pygidium {fig. 16) broad, terminating in 

 a median pair of prominent bluntly tricuspid lobes ; other lobes obsolete. On 

 each side are two deep notches with strongly thickened margins, and laterad of 

 each notch is a pointed projection of the margin of the body representing the 

 missing lobes. A pair of deeply and irregularly divided squames caudad of 

 each notch and two or three simple or finely serrated tapering squames 

 extending slightly laterad of the second notch. There is a pair of spines 

 associated with each lobe, a fourth pair about half way up the margin of 

 pygidium and associated with a small marginal indentation. Anal aperture 

 large and conspicuous, very near the extremity; genital aperture near the base 

 of pygidium. Conspicuous thickenings of the body-wall extend inwards from 

 extremity, partially encircling the anal aperture, and upwards on each side
