the hinder segments somewhat knobbed : pupa very elongate, slender/enclosed 

 in a slight web amongst leaves. 



This conspicuous genus has also simple antennse in both sexes, 

 but here again tlie metamorphosis resembles that of the true Geo- 

 metrse : the imago may be readily known by the elongate tail-like 

 process in the middle of the hinder angle of the posterior wings, as 

 well as by the flavescent hue by which all the wings are tinted.
