Xo mention is made of the size of either the sac or the insects in Fuller's 

 •description, and the figure given in the plate is that of one of the capped 

 glassy tubes covering the epidermis of the immature feinales, before they 

 construct their sac. 



Sac of adult female " complete above but not extending completelv ))eneath 

 the insect, tough, felted, rather flat, elliptical." 



Adult female white, elongate, segmented. Dorsum thicklv covered with 

 short, stout, conical spines. Antenna? compoed of eight joints; the seventh 

 and eighth fused. Legs slender, tarsi longer than tibia, digitules thickened 

 at the tips. Aual tubercles cylindrical, black, with setae. Anal ring large, 

 with eight hairs. 



In the second stage, or immature female. Fuller says : " Pink or lemon 

 yellow ; antennse, legs and tubercles as in adult. Dorsum clothed with 

 long cylindrical glassy tubes surmounted witli conical caps, those on the 

 abdomen being longest."" 



In the description of the sac, and the conical spines on the dorsum of the 

 adult female, this species comes near the Eiiococcus coriaceus group, but 

 the white colour and black tubercles are different from any other known 

 ispecies.
