able to the next species. It has previously come from Vat^ 

 and Totoya. 



12. Diadema elsina^ n. sp. (No. 9). 



AlKed to D. octocula^ but readily and constantly distin- 

 guished by the following characters. Primaries shorter, 

 the orange or tawny belt beyond the cell considerably darker 

 and narrower and with straight margins joining a submarginal 

 streak of the same colour, which tapers from the internal 

 margin, almost to the upper discoidal vein, and encloses a 

 small black ocellus near external angle : secondaries with 

 tlie broad discal tawny area much deeper in colour, uniform in 

 both sexes, but crossed by similar black ocelli ; outer border 

 much narrower and intersected by a tawny line. Primaries 

 below differing principally in the width and straightness of 

 the oblique tawny band ; secondaries with the outer border 

 more regular and usually clouded with brown to just beyond 

 the ocelli. Expanse of wings ^ 2 inches 10 lines, ? 3 inches 

 3 lines, 



I have examined four or five examples of this species. 



13. Diadema lifuana^ n. sp. (No. 9). 



Allied to the two preceding species, but smaller, darker, and 

 with differently ornamented primaries. 



$ . Above dark chocolate-brown ; a tapering submarginal 

 streak of dull deep tavvny^ enclosing a large black spot near 

 external angle : secondaries with a broad, regular, deep, 

 tawny discal belt, crossed by black veins and traversed by a 

 series of eight rather small black spots ; outer border choco- 

 late-brown, bounded within by a well-marked black edge : 

 body dark chocolate-brown. Wings below chocolate-brown, 

 becoming paler towards the outer margin ; a rather thick 

 undulated submarginal line and a narrower marginal line, 

 both black : primaries with the subcostal area black in the 

 cell and crossed by two greyish white spots ; a pale brown 

 diffused streak across the end of the cell, and beyond it a 

 subcuneiform pale testaceous patch, its broadest part in the 

 costal nervure, diffused externally and fading away as it 

 reaches the lower radial nervure ; two subapical white spots, 

 and six black spots with bluish-white centres crossing the 

 disk : secondaries with the disk, from its centre to the outer 

 margin, abruptly testaceous, tinted internally with pink, 

 crossed in the middle by a series of eight rounded black spots 

 with white pupils and broad pyriform chocolate zones ; a white 

 subanal litura between the submarginal an J marginal lines :
