Ptychotheca gen. nov. 



A development of i'ldorodi/stis. 



The forewing of the c? has the membrane from base of cell nearly to hind- 

 margin folded longitudinally so as to form a double pocket : on the u])perside this 

 pocket is open towards costa, on the underside towards inner margin ; the veins 

 beyond cell are partially distorted ; the fold is much more prominent beneath, 

 appearing as a double pleat with a furrow in the middle.
