Until recently Waigieu was considered to be the home of Sch. Tithonus ; and the examples of the ? which 

 reached England were believed to be the representatives of De Haan's type S , and the $ to be their proper mates. 

 These forms are figured in my PI. V. of this work ; but since that plate was published Mr. Doherty discovered the 

 species at Kapaur in New Guinea, on the western coast of the province of Onin, at least 340 miles south-east of Waigieu 

 as the crow flies, and separated from its first habitat by two islands, the whole of the Arfak part of New Guinea, and 

 the McCluer inlet. The females of this form of Tithonus Mr. Rothschild considers to be true representatives of the 

 original type ? : so that the two sexes of the Kapaur examples must be considered distinct from the Waigieu examples ; 

 and that at any rate the Waigieu females belong to a different though closely allied species. This new form he has 

 called T. Tithonus tithonus. Be this opinion correct or not, the discovery of the species in such a new locality opens 

 up very interesting possibilities for the future. These splendid vars. of Tithonus will be found figured on PI. VIa of this 

 work, and a description of them in its proper place. A variety of the S Sch. Paradisea has been taken at Etna Bay, 

 on the north-west coast of Dutch New Guinea, and a little south-east of Triton Bay, or near the foot of the Charles 

 Louis Mountains, or about 150 miles S.S.-East of Kapaur. This fine variety is named flavescens by Mr. Rothschild; 

 and will be found figured in PI. Va. A second var. Sch. Paradisea, v. Meridionalis, Rothschild, is found at Mailu, 

 British New Guinea. This form is much smaller than the last named, and differs much in the extent and shape of the 

 light markings of the primary wings, and the light area of the secondaries ; but the general colour is similar to that of 

 flavescens. A third var. of the 2 from Erima on the German east coast of New Guinea, in Astrolabe Bay, north of 

 Constantine Harbour is called by Mr. Rothschild, v. punctata. This form may well prove ultimately to be the 2 of a 

 very distinct species of Schoenbergia, as it differs in many respects from an)' of the other forms — both in outline of 

 wings, the markings of the primary wings, and the general colour, both of the body and wings : the dark portions of the 

 latter being a warm red-brown on both surfaces — instead of the intensely black-brown of the other varieties ; and the 

 body and the light markings an ochraceous creamy-white, instead of the vivid whiteness of the wing marks of those 

 varieties. [See PI. Va. and descriptions.] These splendid forms therefore give promise of the probability that many 

 new and fine vars. and species of the Gen as Schoenbergia will yet be discovered, when New Guinea is more fully 

 explored ; and that the great island will prove as famous for, and rich in this most superb of all groups of butterflies 

 (a group that may well be called The Butterflies of Paradise) as it is in that most wonderful of all groups of birds, 

 the Paradiseidce , or Birds of Paradise. 



Note. — When writing the portion of this article on the genus Drurya I overlooked the contents of an interesting 

 letter containing valuable information on the localities in which the two species of that genus have been taken on the 

 Congo and in other parts of West Africa, most obligingly sent me in 1898 by Herr Wenig, director of the Musee Royal 

 d'Histoire de Belgique, at Brussels, and which for many months I had unfortunately mislaid; but I now take this 

 opportunity of printing the list of these localities in this place, rather than in a special appendix, to which I add 

 the latitude and longtitude of each place approximately only — though the determinations will not be far out, I think. I 

 will also take this opportunity to thank Herr Wenig for the trouble he so courteously took to send me the information 

 which I required on this point.
