thoracic region, six other spines in two rows ; the extremities 

 of all these spines are dilated into three minute spicules. 

 Vasiform orifice with regularly convex sides and end, the 

 anterior edge concave ; operculum moderate, subcircular ; 

 lingula obsolete. 



Pupa-case intense glossy black, flattish, elliptical ; length 

 about ^V"- Abdominal segments moderately distinct. Margin 

 crenulated, but less conspicuously than in the larva ; there is 

 sometimes a small fragmentary waxy fringe. Dorsum bear- 

 ing rows of short fine hairs in place of the strong spines of 

 the larva. 



Adult form unknown. 



Hah. In Australia, on Banksia integrifolia and on Callis- 

 temon linearis. My specimens were sent from Melbourne by 

 Mr. C. French. 



8. Aleurodes barodensis, Maskell, sp. nov. Plate XXV. — 2. 



Eggs orange - coloured, leather large, oval, pedunculated ; 

 length about jJoin. The eggs and empty sliells are found in 

 large numbers on the leaf. 



Larva dark-brown, becoming later almost black ; elon- 

 gated elliptical ; slightly convex ; abdominal segments fairly 

 distinct ; length about ^V^- Margin minutely crenulated, and 

 bearing a short white waxy fringe, which is fi'equently very 

 fragmentary or absent. Dorsum bearing, within the margin, 

 a row of about thirty-two small simple circular pores ; within 

 these is a transverse row of four on the anterior thoracic 

 region, another transverse row of four on the anterior ab- 

 dominal region, a longitudinal row of four on each side of the 

 abdomen, and one on each side of the vasiform orifice. Vasi- 

 form orifice subconical, the posterior extremity slightly pro- 

 duced ; operculum short, rounded, subconical ; lingula cylin- 

 drical at the base, afterwards widened, finally tapering, not 

 quite reaching the edge of the orifice. 



Pupa-case very dark-brown or glossy-black; very elon- 

 gated, elliptical, with sides nearly straight, the width only 

 about one-third of the length. Dorsum sometimes slightly 

 convex, sometimes flat, sometimes slightly concave ; ab- 

 dominal segments indistinct. Vasiform orifice apparently as 

 in the larva, but difficult to make out on account of the very 

 dark colour of the case. Margin crenulated, and bearing a 

 very elegant, long, snowy-white fringe of slender waxy cylin- 

 drical tubes. There is frequently some white powdery meal 

 on the dorsum, which probably bears pores as in the larva, 

 but it IS most difiicult to detect them. The ventral surface is 

 flat, brown ; the rudimentary organs are not distinct, owing 

 to the dark colour. 



Adult form unknown.
