longer than tibia and bearing long upper digitules, and a long sbarp 

 claw. Anal ring 8-haired. Tubercles almost conical, spined and 

 bearing setae. Dorsum densely clothed with short, conical spines 

 and many protruding spinnerets. 



On Casuarlna humilis (?). The species is clearly an 

 Eriococcus, but the dursal covering could never be regarded 

 as a sac, although, as the insects atfect the axils of the 

 branch and brauchlets, they are completely enveloped. 



10. Eriococcus Gurneyi, sp. n. (Plate XV, fig. 9.) 



9 sac complete above but not extending completely beneath the 

 insect, tough, felted, rather flat, elliptical. 



Adult ? filling sac, white, elongate, segmented : dorsum clothed 

 with innumerable, closely set, short, stout, conical spines. Antenna3 

 8-jointed, joints 7 and 8 fused. Legs slender, tarsus longer than 

 tibia, upper and lower digitules knobbed. Mentum dimerous. Anal 

 tubercles cylindrical, black, spined and with setse. Anal ring large, 

 8-haired. 



Second stage ? active, pink or lemon-yellow. Antennse, legs and 

 tubercles as in adult. Dorsum clothed with long, cylindrical, glassy 

 tubes, surmounted with conical caps ; those on the abdomen being 

 the longest. The insect in this stage is a very elegant little creature, 

 and highly suggestive of a hedgehog. 



On a Rhamnaceous plant, in company with Inglisia 

 fossilis, Mask. The name of my friend Mr. E. H. Gurney, 

 of the N. S. W. Department of Agriculture, is attached to 

 this species. 



11. Eriococcus hakcse, sp. n. (Plate XV, iig. 7.) 

 5 sac of a tough, felted nature, white or buff colour and very 

 convex ; length 0"2, width O'lS, height O^l inch. 



Adult 9 pink ; length 0-15— 0-2 inch. Antennae 7-jointed, 3 the 

 longest, 6 the shortest ; sequence 3, 4, 1, 2, 7, 5, 6. Mentum dimerous, 

 conical, hairy. Legs ample, furnished with several spines, tibia and 

 tarsus subequal, digitules present. Anal tubercles large, stout, taper- 

 ing and spined ; the median margins with 4 to 6 conspicuous spines, 

 laterals with 3 ; with sette. Anal ring conspicuous, with 8 long 

 hairs. Dorsum with many conspicuous, conical spines, a few being 

 larger than the majority ; the margins of each segment bear a pair of 

 much longer acuminate spines, those on the posterior segments being 

 tlie hmgest.
