Chionaspis. 143 



Eggs, yellow to bright orange. 



Habitat on Hedyotis auricularia and other allied species. Scales irregularly 

 distributed, mostly on under surface of leaves. Pundaluoya. Specimens of 

 Hedyotis Lawsonice have been received from Nuwara Eliya, badly infested with 

 this insect. The stems and leaves of the plant are quite white from the multi- 

 tude of scales. If it should ever attack cultivated plants to the same extent, 

 this insect would prove a most serious pest. 



Differs from Ch. vitis in the form of the puparium and female insect. 

 Closely allied also to Ch. litzece, from which it may be distinguished by the more 

 prominent median lobes.
