The cocoa-nut mealy bug (Psciidococcus nipae, Mask.) 

 is a small, round insect (Fig. 118) covered with yellowish 

 wax, which occurs on the leaves, generally in small num- 

 bers, and not grouped into dense masses or colonies. 



The glassy star scale ( Vinsonia stellifera, Westw.) can 

 easily be distinguished by the projections of wax in the 

 form of a star, from which the insect gets its name (Fig. 

 119). This insect does not often occur in sufficient num- 

 bers on cocoa-nuts to become a pest.
