FAM. GEOMETRID/E 23 
Antenna in cf pectinate nearly to apex. Thorax with a dense posterior crest; beneath densely hairy. 
Posterior tibia with all spurs present; in cf dilated, with internal groove and tuft. Abdomen with strong 
median dorsal crests. Frenulum and retinaculum in c strong. Forewing with SC! anastomosing with C, 
SC? arising separately from cell, Ri separate, R? and. M! separate; hindwing with DC incurved, not 
oblique, C closely approximated to cell to well beyond middle. SC? and R! separate, R? and M! 
separate» (Turner, Proc. Linm. Soc. N. S. Wales, Vol. 35, p. 647). « Forewing with costa slightly 
arched, termen rounded, rather oblique, waved; hindwing with termen crenate, tolerably rounded, 
slightly bent in middle » (Meyrick). 
Early stages unknown. 
This genus is unknown to us in nature, but would appear to be the parent of Dindica, Moore.
