This species belongs to the H. picta and //. omata types of 

 Hesperilla. It is closest to H. picta, Leach, but differs from it 

 in having lighter-coloured forewings, fewer spots on the forewing 

 of the male, and the central ochreous spot of the hindwing much 

 brighter and larger. On the undersurface they are similar in 

 having the apical third of the forewing and the whole hindwing 

 of the same general pattern, but these general patterns are totally 

 distinct, and constitute the most marked difference between the 

 two species. The pattern of //. picta is fairly sharply defined, 

 while that of H. Mastersi is mottled, and not at all well defined. 



I have to record the presence in New South Wales of Ogyris 

 genoveva, Hew., and 0. olaue, Hew. Of the former I caught 

 several males flying round the tops of Eucalypts, about 25 feet 

 from the ground, at Corao during March. The latter was caught 

 by Mr. N. W. Hansard at Lawson, Blue Mts., in January.
