Pdlaeococcus dymocki, n.sp. 



This fine species was collected by Miss M. Dymock upon the basal stems 

 above the roots of a small undetermined shrubby plant at Spring Valley 

 (near Hughenden, North Queensland). 



Adult female light biscuit brown or buff coloured, very lightly covered 

 with mealy secretion, chiefly on the margins and under-surface ; broadly 

 convex, rounded on dorsal surface, narrowest in front, very glightly ribbed, 

 broadly rounded behind. Under-surface of head and thorax corrugated, 

 the abdominal portion flattened and slightly flanged on the'margin. Length, 

 one quarter of an inch. Antennae black fringed, with fine hairs, composed 

 of eight segments, first three fusiform, fourth and fifth rounded, sixth and 

 seventh smaller and constricted on either side, eighth as long as the three 

 last combined, elongate, and sometimes appearing to be composed of two 

 fusiformed segments. Legs black, long, with fine spines along the inner 

 margin of femora and tibiae, digitules fine hairs, tarsus long and curved. 

 Epidermis covered with .scattered short hairs and minute orifices. 



Larvae red, clothed with long fine hairs, forming a fringe of three on either 

 side of the anal segment, all over the body and on either side of the antennae. 

 Lightly covered with white meal, probably from the secretion on the under- 

 side of the mother. Antennae, eyes, mentum and legs black ; antennae very 

 long, composed of six segrtients, the last as long as the previous three, swollen 

 and round at the extremity.
