very thinly scaled. A large white patch in basal one-third of wing below 

 median, a broad white postdiscal transverse band running out into long intra- 



nervular projections distad, the upper four of these being more pointed. 



Hind wing ground-colour similar, the postdiscal band more distinctly lunulate. 



Length of forewing : 3 22 mm., $ 31 mm. Expanse : S 48 mm., $ 69 mm.

The $ of lunulata is very similar to that of meeki, but is paler all over, and 

 more rufescent on the wings, while the postdiscal white bands are much narrower. 



I have no specimens from so low an elevation as Dinawa.

Hyperajdas albaserrati Bethune Baker, Ann, Mag. Nat. Hist. 8 (vi.). p. 451 (1910) (Biagi). 



The (J resembles I. Imiulata, but is larger ; it differs at first sight in the outer 

 one-third of forewing being much paler more yellow, and the hindwing is much 

 brighter yellow. All transverse lines are also more distinct. 



The ? differs from $ I. lunulata in being much darker, the white patch in 

 basal one-third of forewing is reduced to a small dot, and the postdiscal bands 

 are much narrower and more cream-coloured.

Cotana lunulata occidentalis subsp. nov. 



(J. Differs from I. albaserrati by the transverse line of forewing being ante- 

 median not median, and the postdiscal band being much greyer. On the 

 hindwing it differs in having the postdiscal line almost straight, being much 

 less crenulate.

Cotana lunulata satisbona supsb. nov. 



(J. Differs from I. lunulaia in being much larger and all the transverse bands 

 and lines much sharper and more distinct. ?. Differs from I. albasserrati in being 

 much paler yellowish rufous all over, and the anal tuft is ash-grey.
