The material of which the ovisac is composed is very close grained 

 arid felty, but so readily adhesive to any object that the slightest 

 touch destroys the characteristic appearance of the structure. At 

 the time of the formation of the ovisac a sparse covering 1 of flocculent 

 material makes its appearance on the dorsal surface of the scale, 

 similar to that of certain other species, notably that described by 

 Westwood (Gard. Chron., 1870, page 308). whose description of the 

 ovisac also corresponds more or less closely to that of the present 

 species ; but as no technical description of the insect itself is added, 

 there is no proof of the identity of Pulrinariu pfiaice and P.floc- 

 cifera. 



The EGG is minute, regularly oval, pale yellow in color, with no 

 discernible sculpturiugs or markings thereupon. The eggs are 

 numerous, but the number, together with the size of the ovisac, 

 varies apparently with the abundance or scarcity of food. 



The newly hatched LARVA is active, pale yellow in color, in form 

 an elongated oval with comparatively few marginal spiues. The 

 anogenital plates reach quite to the margin of the insect and the 

 anal setae are strong and nearly one-third the length of the insect. 

 All appendages are proportionately far larger than in the adult 

 (see fig. 1). Antennae are of six segments. Segment 3 is the long- 

 est, though about equal to 6; segments 4 and 5 are equal and next 

 in length; segments 1 and 2 equal and shortest. Formula 3,6 

 (4, 5) 1. 2. Three hairs are born on segment 3; the 4th bears one 

 rather long hair, while 6 bears seven, of which the terminal one and 

 one other are very long 



The legs are long and stout The tibia is longer than the tarsus, 

 which is, as Mr. Maskell says (Trans Royal Society, S. Australia, 

 XI, p. 103), " an exceptional character in larvae." He cites it as 

 being true of P. 



Flavicans., mask,' larva. Digitules are similar to those of the 

 adult. The rostral loop is long, being over one-half the entire 

 length of the insect. 



The MALE test is 2.5 mm. long by 1 mm broad, elongated oval in 

 outline, with two notches, one on each side, in the anterior one- 

 eighth ; two similar notches lie about two-sevenths of the distance 

 from the posterior end, and one deep anal notch or cleft lies ter- 

 minally in the median line Color hyaline, the semi-transparent 

 pupa showing through the test with greater or less distinctness. A 

 row of ten oval, lustrous, pellucid markings lie along the medium 

 line of the test. Two main cariua?, arising from tlieauterior margina 1 

 notches, approach to within about .3 mm. of each other, then run 

 nearly parallel until nearly opposite the posterior lateral notches 

 whence they converge to form a single line ending in the posterior 

 median notch. Two transverse eariiue connect the main ones, one 

 about .5 mm. from the anterior end and one about .7"> mm. from the 

 posterior end. Other carinae describe reversed curves connecting
