 short, thick, spear-shaped spines, each group consisting of

Adult female oval in outline ; dorsum convex, rounded, 

 dark orange in colour. The dorsum is covered with a white 

 powdery secretion, arranged in one submedian and one sub-

 a yellowish tinge. The adult rests upon a cushion of white 

 cottony matter that contains the young; this cotton readily 

 adheres to anything it touches. The largest specimens are 

 750 millim. long, 5 millim. wide, and 3 millim. high.

 thick, nearly twice the diameter of joint 2. Length of joints 

 variable, joints 3, 6, 5, and 7 being subequal and joints 1 and 

 2 being subequal; sometimes 1, sometimes 2, is the longer. 

 Approximate formula : 8 2 1 5 (3 6 7) 4. Average length 

 of antenna *48 millim. All the joints bear hairs. Length of
