 Aleurodes piperis Maskell, Trans. N. Zeal. Inst., vol. 28, 1896, p. 438. 



Amongst the type material of the MaskeU collection this species

Larva (fig. 6).— Length 0.64 mm.; width about 0.5 mm.; shape 

 broadly elliptical. Abdominal segments not distinctly marked and 

 median ridge not pronounced. Color under the microscope brown; 

 submarginal area with the pigmentation irregular, giving it a mottled 

 or granular appearance. Dorsum armed with a number of prominent 

 spines of different sizes, the position and relative sizes of which are 

 best shown in the illustration. These spines are acute at the tip
