The S 6 are, as a rnlo, niiich ilnlier than the ? ?, reddish grey with an olive 

 tint ; the underside generally dull brick-red, sometimes tinged with olive-yellow ; 

 the ? ?,on the other hand, are redder, withont the grey tint, beneath deep olive- 

 yellow; the ? differs in being olive-drab, without any red tint whatever above, 

 but agreeing with the rest on the underside. In all specimens, cJ and ? alike, the 

 hindmargin is smooth, not crenulated, and the fringe nnicolorons throughout ; 

 the three transverse lines are generally more or less visible, but never conspicnons. 

 While agreeing with typical Hyperijthra in having the cell of hindwing only 

 one-fifth as long as wing, and the costa strongly rounded, the S is entirely 

 without the secondary sexual characters of that genus — viz. the basal gland, the 

 smooth costal area, and the pencil of hairs. In this respect it agrees with the 

 species I called H. simplex from Sula Besi, which, when further specimens can be 

 compared, will probably be fonnd to be the same insect, although Colonel Swinhoe 

 has snuk it as only " one of the many named forms of luteal'' 



For the pale form without red suffusion, I j)ropose the name ab. decolor.

These species are identical ; the insect, according to Meyrick's description of 

 belidearia, is variable in the distinctness of the markings. Meyrick overlooked 

 Walker's species and genus altogether, the type not being in the British Museum 

 Collection.
