AN ACCOUNT OF A COLLECTION OF DIURNAL 

 LEPIDOPTERA 



MADE BY MR. W. DOHERTV AT HUMBOLDT BAY, Dl^'H NEW 

 GUINEA, AND IN NEIGHBOURING ISLANDS, IN THE MUSEU.AI OF 

 THE HOXOUL'ABLE \VALTER ROTHSCHILD AT TRING, ^VITH 

 DESCRIPTIONS OF NEW SPECIES. 



By II. GROSE S:\1ITH, B.A., F.E.S., F.Z.S., Etc. 



THIS Collection was formed by Mr. ^V. DoUerty in the months of September 

 and October 1892, and contains a large number of new and scarce species, 

 of many of which there are long series, for the most part in the fine.st possible 

 condition. 



The series of Lycaenidae and Hesperidae are particularly noticeable in these 

 respects. The Danaidae are numerous, and in this and other families, where 

 very minute differences are considered sufficient to constitute species, and where, 

 even in undoubted species, the variations in the number and size of the spots 

 and in other characteristics are almost infinite, considerable difficulty has been 

 experienced in identifying and separating many of them. 



In such cases \-erbaI descriptions without figures are inadequate to depict, 

 with any degree of certainty, the distinctions existing between closely allied 

 forms, which, even with the aid of carefully drawn and coloured figures, may 

 sometimes be confounded. 



Some of the new species in this paper will be figured in Mr. Rothschild's 

 NoviTATES ZooLOGlCAE, and others I propose to figure in my Rhopalocera 

 Exotica from time to time as opiiortunitv arises. 



Except where otherwise specified, the locality of the captures is Humboldt 

 Bay. 



PART I. 



PAPILIONIDAE. 



PAPILIONINAE. 



1. Ornithoptera pegasus Feld. 

 The two spots on the upperside of the posterior wings of the male are 

 rather more conspicuous than in Mr. P'elder's figm'e. The females agree exactly 

 with his figure of that sex. 



2. Papilio pandion Wallace. 

 A good series of lx)th sexes. In the males the oblique subapical band of 

 white spots on the anterior wings, which is so conspicuous in P. ormeniis Gudrin, 

 and other described species of this group, is reduced to a few indistinct grey 

 markings, more or less obsolete, but represented in all the specimens; beyond 

 these to the apex and jjartially along the outer margin, the rays of grev scales 

 on each side of the veins are rather conspicuous.
