the tips of its long abdominal filaments visible.’’ Prof. Cockerell 
dug it out and discovered the object of its search, which proved 
to be an adult female Margarodes. The appearance of a male 
Margarodes may be gathered from fig. 1, and from the subsequent 
description of M. indicus. 
In my study of this interesting genus I have unfortunately 
not had access to the earlier authors: but Signoret, in his classical 
Essai sur les Cochentlles, has given a useful resumé of the pre- 
vious work on the subject. I append a list of the publications 
that I have been able to consult.

On 
Amongst a collection of Coccidae submitted to me by the 
Superintendent of the Indian Museum, I found three examples of 
a male Coccid that I at once recognized as belonging to this genus. 
The remarkable fossorial front limbs and the presence of long tufts 
of silky filaments on the abdomen permitted of no doubt as to the 
systematic position of the insect. Subsequently, several small 
parcels of empty nymphal cysts of a Margarodes, collected at 
various Indian localities, were received from the same source. 
From one of these cysts I extracted a fragmentary and decayed 
example of the adult female insect.
