Maskell. — On AleurodidsB. 435 



32. Aleurodes holmesii, Maskell, sp. nov. Plate XXXI.— 2. 

 Larva dull-yellow, elliptical, flattish ; length about -^in. 



Margin thickened, almost entire, the crenulations being very- 

 minute and confused. Dorsum bearing, on the thoracic 

 region, six strong rather short spines ; of these, two are 

 median, the four others submarginal. In the earliest state 

 there is no fringe, but in the latest stage there is a fragmen- 

 tary short fringe of vvhite wax. 



Pupa-case dull-yellow, rather lighter coloured than the 

 larva ; form elliptical, flattish, and rather thick; length about 

 Jvin. Abdominal segments moderately distinct. Dorsum 

 bearing a submarginal series of strong short spines ; two of 

 these on the cephalic region and four on the posterior ab- 

 dominal region are large and conspicuous, the other eight 

 (four on each side), on the thoracic region, are smaller. From 

 these spines is produced a quantity of white waxy secretion, 

 which is very fragmentary, often entirely absent ; it scarcely 

 ever seems to completely cover the dorsum. Margin very dis- 

 tinctly and conspicuously crenulated with large thick seg- 

 ments ; these produce a fringe of closely-adjacent waxy tubes, 

 which at first is flat, then becomes a rather thick ring or 

 cushion, and at last becomes so thick as to raise the pupa 

 somewhat high above the leaf, and then it seems as if resting 

 on a very elegantly-fluted white wall ; vasiform orifice sub- 

 elliptical, with concave anterior edge and broadly-rounded 

 sides and end ; operculum broad and short, the posterior edge 

 concave ; lingula very long, extended beyond the orifice, sub- 

 cylindrical, with emarginate sides and compressed extremity, 

 the end rugose, with four rather long and many very short 

 setee or hairs. 



Adult form unknown. 



Hab. In Fiji, on Psidium sp. My specimens were sent 

 by Mr. R. L. Holmes. 



The arrangement of the dorsal spines, and the peculiar 

 lingula, will distinguish this species.
