extremity of the body may be deeply cleft or merely slightly 
indented. In Cerococcus (fig. 2), the anal lobes are strongly 
developed, resembling in character those of the Dactylopiine genus 
Eriococcus. The dorsal lip of the anal aperture is prolonged in the 
form of a prominent triangular median plate which projects 
between the bases of the anal lobes. The anal ring carries eight 
stout flattened hairs. 
Amorphococcus and Anomalococcus may be regarded as aberrant 
forms of Asterolccanium and Lecaniodiaspis respectively, their 
divergence from the type being due to exceptional environment. 
I have included, in the following synopsis, only the six genera 
that occur in Ceylon. It is probable that several of the aberrant 
gall-making Coccids of Australia will fall into this same group. 
Frenchia is almost certainly an Asterolecaniid.
