2. P. taviunensis, Layard : Taviuni (Layard). 



3. P. splendens (Peale) : Kandavu and Viti Levu (Layard). 



4. P. personata (G. R. Gray): Kandavu (Layard). 



It seemed now quite certain, from the researches of Dr. E. Grliffe 

 (cf. J. f. O. 1870, p. 410), that the true P. tabuensis was found in 

 the Tonga group, not, indeed, on the island of Tongatabu, but on 

 the adjoining island of Eua or Eoua of that group. Mr. Sclater 

 was therefore not yet quite convinced, in spite of what Messrs. 

 Finsch and Hartlaub had stated (J. f. Orn. 1870, p. 123), that 

 Peale's P. atrigularis (which he had identified, P. Z. S. 1804, p. 158, 

 as applicable to Mr. Rayner's specimen from Ngau Island, Feejees) 

 was certainly = P. tabuensis, unless, indeed, it should turn out that 

 P. tabuensis had been introduced by the natives of the Tonga 

 Islands from the Feejee group *.

The first two species here described were lent to me by Lieut. 

 Roberts soon after his arrival in England ; but press of work has pre- 

 vented me from determining their affinities until now. 



Family Erycinidi;. 

 Stiboges, n. gen. 



Allied to Abisara, aspect of Nymphidium. 



"Wings with rounded outer margin broad, costal nervure of pri- 

 maries terminating abruptly at about the middle of the costa, opposite 

 to the end of the discoidal cell, subcostal with five branches, the last 

 two forking to apex ; upper radial emitted from the inferior margin 

 of the subcostal near its origin ; lower radial nearly equally dividing 

 the discocellulars, which are concave ; second and third median 

 branches emitted near together ; precostal of secondaries short, 

 oblique, directed backwards ; costal nervure short, straight, oblique, 

 terminating at basal third of costa ; subcostal forking beyond the 



* Mr. Salvin kindly sends me an extract from the "Voyage in search of La 

 Perouse" (translated from the French, 2 vols. 8vo, 1800) in illustration of this 

 point. " On the morning of the 2lith March we landed (on Tongataboo). . . . 

 They (the natives) sold us several birds; among others a charming species of 

 Lory, which they assured us had been brought them from Fidgi." — Tom. cit.
