Genus ASTEROLECANIUM Targioni Tozzetti 
The members of this genus are all of small size, and have the 
female and immature stages completely inclosed in a horny and, 
usually, more or less transparent test or sac which bears a mar- 
ginal fringe of filaments, usually brightly colored in life. The 
legs are wanting, the antennze very minute, and there is a row, 
sometimes more than a single pore deep, of 8-shaped gland pores 
around the body margin, while additional pores of this type are 
frequently found on the dorsum. At present only one species 
from the Philippines has been examined, although, considering 
the large number which have been reported from the leaves of 
bamboo from Ceylon, it is difficult to believe that there are no 
more species in these Islands,
