Maskell, N.Z. Trans., Vol. XIV., 1881, p. 223. 
Adult females enclosed in a sac, or test, of secretion so 
closely felted as to appear waxy; round the edge of the sac a 
double fringe of glassy tubes; apodous; antenne absent. Anal 
tubercles present im all stages. 
The differences between this genus and Asterolecanium (see 
above under Lecanidine) are not to be made out from external 
examination of the sac, nor without close investigation. It is 
possible, indeed, that Asterolecanium should be removed from the 
Lecanidine and united with Planchonia.
