Biflfers from peranthus in the more bluish colour of the wings. 



Snellen calls this aljerration a remarkable transition to " Hoisduval's var. B 

 (adamanthius Feld.)." I do not see how this can be, us intermedius agrees, 

 according to Snellen, with perantlnifi in shape and size, and is distinguished from 

 that Javan insect oul^' by the (variable) tint of the bluish green area of the wings.

The bluish green area of the forewings extends in Ruber's type as far as the 

 origin of the second median nervule, as it does in the specimens from Sambawa, 

 Flores, etc. 



The size of the subapical green liaud of the forewings, by wliich Kobor differ- 

 entiates this form from typical jjencnlhus, is extremely variable; in the female, 

 which does not remarkably differ in pattern from the male, this band is less green 

 than iu the other sex.

S. The greenish blue area of the forewings extends beyond I lie aiiex of the 

 cell, and reaches sometimes a little farther than the junction of the fourth and fifth 

 subcostal nervules ; in other examples it is more reduced, just reaching the very base 

 of the second discoidal vein. The green subapical band of P. peranthus Fabr. is here 

 represented by a few bluish or huffish scales at the apex of the wing. Most specimens 

 have four cottony stripes — one each upon the two lower median nervules and the 

 submedian nervure, and one betw(!en the submedian and tliird median vein; the 

 three posterior . stripes are mostly merged together; in many individuals the last or 

 the last but one, or both, are wanting, so that in certain examples there are only two 

 small patches standing upon the two lower median nervules. Upon the di>eoeellular 

 veinlets there stands mostly a conspicuous black spot. 



Below, the specimens are especially variable iu the size and distinctue^s of the 

 tricolorous subdiscal spots of the hindwings. 



?. This sex is rather more purple-blue than the male in certain lights, and 

 the blue area is a little less extended, reaching in one of my two specimens just to 

 the discocellular veins on the forewings, while in the other it extends a little beyond 

 the a]iex of the cell.
