 Orthottenia formosana, Curtis ? * 



* The following is Mr. Curtis's description of his 0. formosana : — " Pale fuscous ; thorax and superior wings rosy chestnut ; the latter with a 

 considerable number of waved, transverse, pale shining lines as far as the middle, beyond which are two more compound ones, with several shorter 

 on the costa, and a row of spots of the same colour at the base of the cilia ; abdomen ochrcous at the apc-c. Similar to O. nubilana of Hiibner, 

 in size and colour ; but the superior wings are a little less obtuse, their colour is very different, and the bar across the middle formed by the 

 waved lines is narrower and more irregular." Locality unknown.
