S34 Mr. E. Boubleday on some new Diurnal Lepidoptera, 



near the anterior margin, five vittse around the cell, a series of 

 eight round spots near the margin, and four between these and 

 the terminations of the vittse, all whitish. Cilia fuscous, spotted 

 with white. Below, anterior wings with the disc fuscous, the 

 apex light brown, the markings nearly as above but more defined ; 

 posterior wings brown, the discoidal cell and abdominal fold 

 whitish, the vittse nearly as above but much less distinct ; the 

 vitta between the first and second discoidal nervules terminated 

 by a rounded spot ; the inner row of whitish dots very small, the 

 outer much larger. 



Head and thorax black, spotted with white, the latter gray pos- 

 teriorly. Abdomen gray at the sides, fuscous above and below. 



This insect in form and in some respects in colouring resem- 

 bles P. dissimilis. It has the cell of both wings closed. Of three 

 specimens in the Museum collection, no one has the antennae 

 perfect ; a fragment on one specimen is black.

Above, all the wings fuscous black, the anterior with a broad 

 band-like spot, commencing near the costa beyond the middle, 

 and extending towards the anal as far as the lowest median ner- 

 vule. This spot is of a brilliant metallic, changeable blue, much 

 paler and less changeable externally. On the posterior wings is 

 a large patch of the same rich blue, paler in the centre, occupy- 

 ing the whole disc of the wing. Below, all the wings less black 

 than above, the outer margin paler ; this pale portion bounded 

 internally by an undulated pale or whitish striga, becoming 

 brown towards its termination at the anal angle of the posterior 

 wings : between this and the margin is another less distinct si- 

 milar striga. The anterior wings have besides two fuscous strigse 

 in the discoidal cell inclosing a paler space, and a third striga 

 commencing on the costa beyond the cell and extending ob- 

 liquely nearly to the anal angle, slightly bordered internally with 

 whitish. The posterior wings have a transverse fuscous striga 

 near the base, and another commencing near the middle of the 

 costa and reaching nearly to the anal angle. Just within the 

 pale submarginal striga near the costa is a round yellowish spot, 

 inclosing a brown one placed towards its outer margin, and be- 

 tween the first and second median nervule a round black spot 

 sprinkled with blue atoms anteriorly, and surrounded by a yel-
