* The species Lonchaea f piinctipennis, Walker 1860, from Macassar, and Lonchneaf inops. 

 Walker 1859, from Aru. Mysol and Ceram, evidently do not belong to the present genus. 



fWalker, who describes only the female, says nothing about the colour of the squamulae, 

 which are assumed here to be blackish (according to the colour of the wings), at least in 

 the male sex.
