Adult female (figs. 1-3) usually globular, but 

 slightly longer than broad, and sometimes slightly 

 produced in front (fig. 3) ; smooth and somewhat 

 shining, and under a lens faintly punctate. Colour 

 bright ochreous yellow, or pale brownish-yellow, usually 

 with four irregular, transverse, dark chestnut-brown 

 or blackish bands on the thoracic area, which are 

 broadly interrupted on the dorsum; there is also a 

 short irregular band between the first and second and 

 the second and third thoracic bands; the succeeding 

 bands are much less conspicuous, and gradually 

 diminish in length and breadth as they approach the 

 anal orifice ; cephalic area (fig. 3) with a double series 

 of spots, which sometimes coalesce and form indistinct 

 bands or blotches ; midway between the latter and 

 the first thoracic band is a pair of much larger spots, 

 and there is a similar pair of spots between the first 

 and second and the second and third thoracic bands. 

 In a small specimen before me the bands and spots are 

 less distinct and have coalesced in places. Ventral 

 surface attached to branch (fig. 1 a) very small, more 

 or less circular, and completely covered with a rather 

 thick layer of tough, white secretion. Anal orifice 

 (figs. 1 a, 7) linear and constricted towards the centre. 

 Antennae (fig. 4) of six joints, of which the third is
