On hindwiug the discal black spots are very heavy in ti/pe-syecimeu, the 

 anterior one joined to the second by means of some black scales; in the second 

 specimen these spots are not larger than in brassolis brassolis. 



Underside: forewiug, median black bandlike patch sharply defined, veins 

 traversing it not pale; patch is 10 mm. wide at the subcostal nervure; its onter 

 edge is irregularly indented between subcostal nervure aud vein 4; the portion 

 between veins 3 and 4 is nearly 1 mm. longer than that behind it ; inner edge of 

 I>atch forms a rounded angle, the point of which lies upon the median nervure. 

 Hindwing, disc aud onter-margiual region with very few brown scales ; brown band 

 at the basal side of the submetallic grey area at abdominal margin narrower than 

 in the other forms of L. brassolis; no black spot at the apex of the cell. 



Forewing : length 46 mm., breadth 28 mm.

 6. Delias aruna rona subsp. nov. 



c?. Black border to wings above slightly narrower tlian in aru/ia from the 

 mainland of New Guinea ; the red discal area of the underside of the hindwing only 

 half the size, extending from apex of cell to base of vein 7, aud being much dusted 

 over with black scales. 



Hab. Ron I., Geelvink Bay, 1 6 (W. Doherty, July 1897). 



I shall not be surprised if there turn up some day in collections from the 

 region between Dutch and British New Guinea specimens of aruna which entirely 

 link aruna together with inferna. 



7. Delias madetes G. k S. 



Messrs. Godman & Salviu described both sexes of this species from New 

 Ireland (now " Nen Mecklenburg ") and figured {P.Z.S. 1879. t. l.j) the upper- 

 and underside of the male. In the explanation of the plate the underside is 

 erroneously said to be that of the female ; this misprint would have been found out 

 by Mitis, no doubt, if this monographer of the genus had compared Messrs. Godmau 

 & Salvin's description of the two sexes, in wliich it is stated that the ? has on the 

 forewing below " no yellowish spot spreading from the inner margin over the 

 median branches." The absence of such a light patch from the underside of the 

 forewing of honrathi Mitis ? from New Britain (= Neu Pommern) was, however, 

 the chief character by which Mitis distinguished his honrathi from madetes ? ; 

 this difference docs uot exist. 



I have lately received 2 cJ<?, 1 ¥, of i). madetes from Neu Hannover, collectetl 

 by Captain H. C. Webster in February and March 1897, and have also 1 S from 

 New Britain, obtained by the same collector on a previous exj)edition, which, 

 together with the figure.^ given by Godman & Salvin aud Mitis, enable me to 

 point out the following slight dill'ercnces betweeu the two forms oi madetes : — 



$. In Z). madetes honrathi from New Britain the black ajiical area of the 

 forewing above and the black border to the hindwing are wider than in nuuletes 

 madetes ; in the latter tiio colour of hindwing passes into sulphur-yellow near the 

 outer edge of the wing, while in honrathi the sulishur-yellow colour is fouud only
