Signoret, 1 iu his paper on the Coccidae, merely quotes the imperfect 

 description of Anderson, and gives no details. Under these circumstances 

 I have sent examples to Mr. W . Maskell for description, as I have not 

 leisure to take the work up myself. I do not think that there is any 

 danger of this insect doing much damage to tea. If it does become 

 troublesome, the application of kerosine emulsion by spraying to the 

 leaves containing the larva will quickly destroy them and prevent their 

 spreading. The waxy portion of the adult female may possibly be used 

 as an article of trade like the insect- wax of the pela in China, but of the 

 uses of the Indian wax we know nothing yet.
