516 Mr. H. Grose-Smith on new 



and a space above the subcostal nerviire not quite reaching 

 the costal margin. In H. osyris, H. isis, Stgr., and H. serapis^ 

 Stgr., this pale space is white and extends beyond the cell to 

 the inner margin. 



On the underside the pale transverse band below the cell 

 of the anterior wings to the middle of the inner margin is 

 narrower than in H. osyris, and on the posterior wings the 

 discal ocelli are smaller and the fulvous rings surrounding 

 them are more dusky. 



T^he. female differs from the same sex of H. osyris in similar 

 respects. 



Exp. of wings 1\ inch. 



Hab. Samarai [Woodfo7-d) and Tupulamu, British New 

 Guinea. 



Described from a pair from the former place and two males 

 from the latter place. 



In Mr. Grose-Smith's collection. 



Thysonotis lygia. 



Male. — Upperside. Both wings dull blue: anterior wings 

 with the costal and outer margins narrowly greyish black; a 

 patch of white scales in the central area below the cell at the 

 junction of the submedian nervules with the median nervure. 

 Posterior wings with the outer two thirds of the costal 

 margin to the apex broadly white, and a broad greyish-black 

 outer margin, becoming wider towards the anal angle. 



Underside. Anterior wings white, with a broad black band 

 on the costal and apical margins, which extends over the 

 up])er third of the cell and becomes wider towards the apex, 

 thence narrowing along the outer margin to the outer angle. 

 Posterior wings closely resemble those of T. phrosOy Grose- 

 Smith, but the subbasal black band is narrower and the 

 white band outside it extends further alono; the costal margin 

 to the apex ; the black spots in the submarginal blue band 

 are less elongate ; cilia of both wings black. 



Female. — Ujjperside scarcely differs from T. phroso, but on 

 the posterior wings the costal white area is wider. 



Underside also closely resembles T. phi-oso, but on the 

 posterior wings the subbasal black band is narrower and the 

 basal blue area is more extended. 



Exp. of wings, (? Ij, ? If inch.
