GENUS 2. Lipoptycha, Ld. TYPE burgnionana, Dup. 



So far we have differentiated four species, three of which 

 have already been described and named. The males differ 

 but little, but the females show much stronger difference. 

 The wing markings of all are very similar. We have not 

 examined the type. 



Valva constricted before the cucullus. Uncus atrophied, 

 practically naked. ^Edosagus short on peduncle; cornuti 

 deciduous; anellus lobes large, ovate, spatulate, scobinate.
