()22 Rev. G. Hulstaert 07i some 



collection wliicli, unfortunately, was unlabelled. Altliougli 

 tliere was some probability that this specimen came from 

 Merauke (Southern Dutch New Guinea), I did not give any 

 locality, as I was uncertain, especially as D, argenthoAa, F., 

 was not then known from New Guinea. Gonsiderino-, how- 

 ever, the history of our collection, it is very probable that 

 this female came from Merauke. This has been confirmed 

 by a letter from Mr. G. Talbot, who was about to publish 

 the description of a female specimen of D. argenthoni. in 

 the Fruhstorfer collection coming from this locality. This 

 description, which the well-known lepidopterologist kindly 

 communicated to me, agreed with the specimen described by 

 me as ? f. halli, and Mr. Talbot also considers them the 

 same. Thus the New-Guinean origin of ? f. halli is suffi- 

 ciently certain, and this form is to be considered as a good 

 local race. 



In addition to this female, our collection contains an 

 unlabelled D. argenthona ^ , which probably also came from 

 Merauke for the same reason as indicated for the female, 

 and which I think to be the ^ of D. a. balli, although it 

 differs but slightly from the typical Australian race. 



In accordance with these considerations, I now describe 

 this c? specimen, adding a more complete description of the 

 $ than that given originally in this Magazine. 



(^ . Above, — Almost completely like true argenthona. 

 Fore wing : subapical markings smaller, shorter ; black 

 border rather far from cell, regularly rounded and narrowed 

 proximally, only 3-4 mm. on vein 4, 1 mm. below vein 3 ; 

 black costal border closely irrorated wdth white to beyond 

 middle. Hind wing : black border hardly dentate on veins, 

 which are not black at their extremit}^, except vein 6. 



Below. — Fore wing : black costal border entering 2 mm, 

 into cell, covering the upper discocellular. Apical black, 

 reaching the extremity of the cell, but leaving a proximally 

 open white spot on middle discocellulars ; subapical white spots 

 smaller than in typical argenthona, but larger below than 

 above ; the spot between veins 4-3 touching discal white ; 

 black border dentate on vein 3 and a little on vein 2, covering- 

 vein 4 almost completely, regularly rounded, 2 mm. broad 

 above vein 3, 1 mm. between veins 3 and 2. Hind wing : 

 basal part yellow, white beyond origin of vein 7 and at 

 extremity of cell between origin of veins 6 and 3. Outer 

 black area regularly rounded-incurved, touching cell only at 

 origin of vein 4 ; a small red discocellular spot, separated 

 from the black area ; red submarginal patches smaller than
