 markings showing through.

One c? from Pergusson Island, November.

Diplodesma gen. nov.

 the first and second, one after the other, running into and coalescing with the costal. 

 Hindwings with last two medians and both subcostals stalked. 



Type : Diplodesma celataria Wlk. 



The species which I described as IdiocJdora contrada (Nov. Zool. III. p. 107), 

 from the Khasia Hills, is evidently identical with this, and my name must sink 

 \^'alker's type of celaiavia was from Sula.
