The following statement occurs in the original description of cauda- 

 tum (49, p. 215) : 



Margin of body with a series of rather large paired pores at intervals of ap- 

 proximately four times their own longer diameter ; with an irregular sub- 

 marginal series of very much smaller paired pores. The paired pores are 

 inconspicuous and difficult to demonstrate. 



Actually, the smaller paired pores are the marginal, and the larger 

 pores are in the submarginal area of the dorsal surface. The marginal 

 8-shaped pores often occur at varying intervals. The dropping out of 

 pores at various points and the variability of the terminating point 

 of the 8-shaped pores probably are due to growth against hairs or 

 veins of the leaves. 



The species is closely related to pseua lorwiliaris, but as a rule is 

 much larger, being 1.4-2.75 mm. long instead of 0.7-1.2; the marginal 

 8-shaped pores are usually at least twice a pore's length apart and they 

 terminate around four times the length of an apical seta from the 

 bases of apical setae. Asterolecanmm caudatum also has 3 to 6 instead 

 of 6 to 14 quinquelocular pores in each spiracular pore band. 



Asterolecanium ceriferum variety ceriferum Green 



(Fig. 13, G-M ; pi. 8, P) 



Described in 1909 (4$, pp. 32J+-325). 



Habit. — "On leaves of a species of bamboo, the insects resting in shallow 

 pits on the under surface of the leaf, these hollows appearing on the upper 

 surface as raised orange-coloured patches bearing ridge-like rows of hyper- 

 trophied cuticular cells." 



Test of female.— "Test of adult female elongate, narrow; lateral margins 

 approximately parallel, extremities rounded. Dorsum moderately convex, the 

 posterior third depressed and slightly concave: sides and front almost per- 

 pendicular, slightly sloping inwards, demarked from the dorsum by the angular 

 marginal line; posterior extremity free, the under parts sloping sharply inwards 

 so that, in profile (fig. 4), it appears to be sharply pointed. Ventral surface 

 convex, owing to a marked depression in the leaf beneath the insect. Margin 

 with straight stout glassy colourless filaments, rather widely spaced. longest at 

 the two extremities. Sides thickly coated with opaque, white, mealy secretion, 

 which extends slightly over the margin, concealing the bases of the glassy fila- 

 ments. Colour, during life, pale lemon yellow, darkening afterwards to ochreous. 

 Length 1.5 mm. Breadth 0.5 mm." (',J. p. 824.)
