Aleurodes bambusse n. sp. Plate IV, Figs. 1-9. 

 Egg. Length '25 mm. x *11 mm. 



Colour light brown. Surface sculptured with hexagons. Attached 

 in an upright position to leaf by a short peduncle. 

 Larva 1st stage. Size *35 mm. x *2 mm. 



Shape elliptical ; narrow for its length. Colour deep black ; dark 

 brown under the microscope. The dorsum is completely hidden by a 

 quantity of white fluff which is produced by a series of submarginal 

 pores. There is an elevated mesio-dorsal ridge extending anteriorly 

 almost to the margin and posteriorly to the vasiform orifice. Segments 

 of abdomen fairly distinct. Margin crenulnted, bearing a series of 

 closely apposed pores which produce a regular but somewhat short hori- 

 zontal fringe. Ventrally just within the margin a series of pores which 

 produce a scanty white secretion. There are four long setae on cepha- 

 lic and four on caudal margins. On the dorsum there are four long 

 stout curved spines which are situated a pair on the cephalic and a pair 

 on the anterior edge of the abdominal region. They are placed on 

 the sides of the medio dorsal ridge. The spines point backwards. 

 Each spine is about half the length of the body, the anterior pair being 

 slightly longer. Two short stout curved spines are situated one on each 

 side of the vasiform orifice. Vasiform orifice large elevated on a tuber- 

 cle. It is apparently similar to that in the puparium but owing to the 

 colour is difficult to make out. 



Larva 2nd stage. Size "55 mm. x *3 mm. 

 Similar except in size to larva 3rd stage. 

 Larva 3rd stage. Size 1 mm. X *55 mm. 



Shape elliptical, somewhat broader proportionately than in the first 

 stage. Colour dense black. There is a distinct mesio dorsal ridge which 

 is somewhat slighter than in the preceding stage. Abdominal segments 

 distinct. Area surrounding vasiform orifice darker than the rest of the 

 abdomen. Margin broad crenulated. Mesad the margin ends at a broad 

 ridge which separates it from the rest of the dorsum. Along its edge 

 are a series of large closely apposed pores which produce a short but 

 abundant horizontal fringe of wax. The upper surface of the margin 

 bears a large number of extremely minute pores. These pores produce 

 a quantity of white fluffy wax filaments which curve inwards and 

 cover the dorsum. Ventrally a little within the margin there are a 

 series of pores which produce a small quantity of wax. The dorsum 

 is covered with a number of stout spines. There are : a pair on the 

 cephalic region at end of mesio dorsal ridge and nearly on the margin ; 

 two pairs placed fairly close together on the cephalic region ; a pair placed 

 widely apart on the thoracic region ; immediately behind this pair there
