Very closely allied to Arbas of Cramer, this species has a brilliant lilue gloss on the outer marKiu 

 of the anterior wing, and the costal margin of the posterior wing. Arbas has a purple gloss on the 

 outer margin of both wings. This species has the band on the underside of the posterior w-ing 

 continuous ; in Arbas it is broken in the middle. They both have the submarginal line of black spots ; 

 but in Arbas they are sometimes wanting betw'een the large .spot and the anal angle, and are replaced 

 by a continuous white line. The Female of Avbas docs not difler from that of Euoras except as to the 

 band of the underside. Both of the males have a pectdiarity of colouring which I have noticed in very 

 few Butterflies. If you wish ti.i see the bright colours to perfection, you must turn the insects with 

 their heads from the light ; and in this position I have cokiured them : the colours are invisible in 

 any other light.
