Butterflies from the Pacific Islands. 177 



Partkenos thesaurinus. 



^ . Upperside bright brown, less olivaceous than P. the- 

 saurus, Mathew. Anterior wings : the apical portion nearly 

 black, the brown streaks and markings becoming nearly 

 obsolete ; the submarginal brown bands are much narrower 

 and the discal transverse band of spots is much whiter than 

 in that species. On the posterior wings the three basal dark 

 bands are narrower, the space between them being wider and 

 the lunules in the submarginal band more conical in shape. 



Underside browner than in P. thesaurus, especially on the 

 posterior wings, in which the oblique band of obscure dusky 

 bars which crosses the disk is brown instead of black, as in 

 M. thesaurus, and the pale spaces on either side of the row of 

 dark streaks below the band are less bluish grey and more 

 tinged with brown. 



Expanse of wings 2f inches. 



Hah. Santa Cruz (PFooc^brc?). 



This butterfly is considerably smaller than P. thesaurus, 

 being nearly the same size as P. aspila, Honr. 



Tenaris melanops. 



? . Upperside white ; anterior wings with the lower third 

 from the lowest median nervule, and thence across the cell to 

 the costal margin, and the costal margin broadly to the 

 apex fuliginous grey ; the veins, except where crossed by 

 the grey colour, are white. Posterior wings with the costal 

 margin to the apex broadly grey, thence along the outer 

 margin more narrowly grey, until that colour merges in the 

 white lower part of the wings ; on the disk, between the 

 median nervules and a little on either side, is a very large 

 diffused fuliginous greyish-black spot, in which, a little above 

 its centre, is situate a large cluster of lavender-coloured scales ; 

 at the lower end of this cluster is a pure white spot, and near 

 the outer edge of the black spot is another small lavender 

 spot ; near the apex is another small lavender spot surrounded 

 by black. Towards the base the wings are clothed with long 

 yellowish-brown hairs. 



Underside. Anterior wings as on the upperside ; posterior 

 wings with two large fuliginous brown ocelli, one of which is 

 situate on the margin near the apex and the other on the 

 disk extending over the submedian nervules ; both ocelli are 

 centred by a white spot partially surrounded by a cluster of 

 lavender-coloured scales, situate in a circular black zone ; 

 outside the zone is an indistinct fuscous ring, outside which,
