PAPILIONIN^. 89 



We separate this as quite distinct from tlie otlier races, and assign Gommixta 

 as, apparently, representing its dimorphic form. It is a fair mimic of the blue- 

 tinted Euploeine butterflies Menama mndesta and Pcnoa Limborgii, or the allied 

 Fenoa Alcathoe. 



CHILASA COMMIXTA (Plate 505, fig. 2, 2a, S)- 

 Papilio Clylia, aber. Commixtus, Rothschild, Nov. Zool. ii. p. 367 (1895). 



Imago. — Male. Upperside rich dark purpurescent brownish-black. Foreunng 

 darkest basally and faintly flushed with blue ; with a marginal and submarginal row 

 of small feebly-marked white-speckled spots, a discal and a lower inner-discal series 

 of similar-scaled short feeble streaks, and also a slender lengthened streak below the 

 submedian. In one specimen from Bassein, the lower only of the submarginal and 

 marginal small spots are apparent. Hindwing with the apical half of the cell, seven 

 discal elongated broad white sagittate streaks, each of the latter extending inwardly 

 to the base of the respective interspace; followed by the submarginal white broad 

 dentate spot and ochreous anal spot, and the marginal narrow ochreous or narrower 

 white lunules. Underside. Forewing with the markings as on upperside. 

 Hindwing with the discal white interspaces as on upperside, the cell and the two 

 upper interspaces being only feebly white-speckled ; submarginal dentate spots 

 white and broad, marginal lunules ochreous. 



Expanse, c? 4 to 4|- inches. 



Habitat. — Khasias ; Burma. 



DiSTEiBUTiON. — Mr. Ernest Swinhoe has received several specimens of this foj'ui 

 from his native collectors in the Khasia Hills. Males, from the Khasias, are in the 

 collpction of Mr. W. Rothschild and of Mr. P. Crowley. Col. C. Swinhoe possesses 

 an exactly similar male, from Bassein, Lower Burma, taken in November. 



This is, ajijparently, the dimorphic form of P. Papone, and differs from the normal 

 dimorphic form {dissimilis) of the other races, in not possessing — or not having yet 

 acquired the fully-developed white streaks on the forewing, as are always present 

 in that form.
