(Plate XIX., Fig. 26.) 
Adult $ spinning ovisac, approximately 4 mm. long, pale olivaceous in 
colour, uniformly covered with v^hite meal. Lateral filaments absent. 
Caudal filaments 2 ; strong, v/hite, about one-third the length of the 
body. In removing insects from ovisacs these are usually broken off, 
so that the majority appear to have no caudal filaments. Half-grown 
females usually have 4 to 6 caudal filaments, the two median ones 
longest and thickest. 
Ovisac : The ovisac, when completed, is an elongate sac, which may 
attain 6 mm. long. It appears longer owing to the projection of the

anterior half of the insect in front. The posterior half of the ^ is hidden 
by the ovisac which has parallel sides, is but slightly broader than the 
insect, and is broadly rounded behind. It is white and cottony, 
reminding one of the ovisac of a Piilvinaria. 
Ova : The eggs are very pale yellow in colour,0-31 mm. long by 015 mm. 
broad. 
Larva : Elongate, active, pallid opaque, with comparatively long 
antennae. Length, 0-36 mm. ; breadth, 0*18 mm. Antennae 6-jointed, 
with 6 longest and terminating in a distinct conical projection. Other 
segments subequal. Anal tubercles moderately produced, each with a
