Four subspecies compose this .species : — 



(a) : P. ccmmts Westw. from Java ; 



(6): P. caunus aegicdns Dist. IVoin ^Malacca and Sumatra; 

 (c) : P. caunxLS mendax subsp. iiov. from Borneo ; and 

 ((/) : P. caunus danisepa Butl. from Teuasserim to Assam. 



(«): P- caunus Westw., forma t\i>. [S]. 

 This seems to be the rarest form. My single mule specimen agrees almost 

 exactly with Westwood's figure. 

 The female is imknowu.

(b) : P. caunus aeg'ialus Dist. [c?].

(J. The white i)atch in the apex of the cell of the forewiugs is larger than in 

 caunus ; the suhmarginal spots are smaller. llindwings a little more rounded, 

 with the median nervules more thinly black.

The type-specimen of aegkdus Dist., now in my colk'ction, does not differ from 

 (hat oi velulinus Vi\xi\. in the British Museum, except in the submarginal markings 

 of the llindwings, which are a little smaller in velutinus; one of m_v three aegialus 

 from JIalay Peninsula has these spots, however, not larger than the type of vdutinus. 



(c): P. caunus mendax subsp. nov. [c?,?].

The Bornean form, which erroneously is regarded by all authors as belonging to 

 tvpical caunus Westw., differs considerably from the .Favan race, and must .«tand as a 

 subspecies of caunus. 



S. Upperside : both wings violet-blue. Forowings with the white patch in the 

 apex of the cell larger than in cauniis Westw. ; submarginal spots smaller. Hind- 

 wings more rounded; white markings reduced in size and number; there are only 

 four spots, namely, one streak posteriorly within the cell and another beliind the cell, 

 lx)th rather long and broad, and two very small spots between the median nervules.
