back of the coccid, with encircling plates htting round it. From 

 this centre there are usually seven, but sometimes eight, flattened 

 plates, broad at the base, but each terminating in a fine point 

 standing out like the rays of a star. Width across, 4 mm. 



First stage, Q. Light brown with yellowish tints; dorsum 

 slightly convex; general form oval, with two well-defined arcuate 

 impressions on each side between the cephalic, thoracic and 

 abdominal regions; rounded at the apex, with a deep anal cleft. 

 At the base of cephalic region are three stigmatic spines with a 

 group of small tubercles; at the base of the thoracic are three 

 large projecting spines, with smaller ones on either side, and a 

 much larger stigmatic spine on the dorsum; on either side of the 

 anal cleft, a long stout spine and two small ones. Antennae 

 tapering, apparently composed of six joints, third longest. Legs 

 long, femora thickened, tibia long, slender, tarsal claw pointed, 

 digitules spatulate at tips. Length, 3 mm. 



Second stage, £ test. Composed of white wax ; the basal por- 

 tion produced on the outer margin into seven, raised, rounded ribs, 

 tapering to the extremities; a central rounded mass slightly con- 

 stricted at the base, and depressed on the apex with a central key- 

 hole-like pit directly over the back of the enclosed coccid. Height, 

 8 mm. 



Test of adult Q. A rounded bell shaped mass of white wax. 

 Height, i inch; diameter, f inch. The ribs or rays of the earlier 

 stages, indicated by slight ridges down the sides, extending to 

 short fingers on the basal margin. 



Adult Q. Chocolate-brown, probably dull red when alive; 

 general form hemispherical, with the basal marginal fold fitting 

 close against the bark; ventral surface contracted, forming a large 

 cavity packed with eggs. The cephalic lobe densely chitinous. 

 Derm with small, oval, translucent, glandular pores; anal process 

 very prominent, apparently contracted at the extremity ; stigmatic 

 spines on the marginal fold projecting through the enveloping wax 

 with filaments. Height / \ inch.
