apex, very pale flavesceut or greyish-white : wings fuliginous, with 

 a series of minute pale marginal spots not reaching anal area. 



This species seems to vary in the amount of dark coloration 

 contained in the lower pale marginal spot to tegmina. 



Length excl. tegm. G to 7 ; exp. tegm. 20 to 24 milliui. 



Hah. Burma ; Tavoy {Coll. Dist.). Tenasserim ; Myitta {Do- 

 herty). — Borneo. 



A rather common Bornean insect, incorrectly recorded by 

 Walker as from Africa. 



The Flatoides guitatus, Walk., from China, may prove to be a 

 varietal form of this species.

Dr. Melichar, presumably without seeing the types, has included

 marginalis. Walk. (Borneo, nee Africa), liicania rujifrons, Walk.
