SOME NEW LEPIDOPTEEA FKOM 0151 

 By the HON. WALTER ROTHSCHILD. 



THE very little explored islaml of Obi major (Ombira) was visited by 

 Mr. William Uoberty in iSe|)tember 18',IT. The collectiou of Lepidoptera 

 made at a place railed Laiwiii on Obi, tbongh not very large, is of bigb interest, 

 as Olii is geograjibically intermediate between the Southern and Nortlieru Molnceas, 

 wliich, witli comparatively very few e.xcejrtions, are inhabited by dillerent well 

 marked subspecies, and shows that the Lepidoptera of Obi are much more similar 

 to those of Batjaii, Ternate, and Halmaheira than to those of Amboina, C'erani, 

 and Burn, a good many forms being even identical with those from the Northern 

 Moluccas. 



i'.\rii.iii.\iiiM:. 



1. Papilio sarpedon crudus subsp. nov. 



S- Somewhat smaller than unthci/on. Upperside : band euniparutively wider 

 than in (intliedoii, measuring at vein 1'' of forewiug I'nmi JO mm. (type) to 8 mm. ; 

 submarginal spots of ])indwing somewhat less arched than in the Northern 

 Moluecan form ihdingeiisis Rothsch. L'nderslda : forewing in both individuals 

 with a minute dot before vein 8 at the discal side of the band; hindwing with 

 the red spots very jirominent ; the black inters]>ace between the costal red mark 

 and the median band narrower than the red mark : a ri'd spot between veins 6 and 

 7 as in dodinyensis. 



Two males. 



2. Papilio aristeus bifax subsj). nov. 



<J. Upperside : forewing nearly as in j(w/7«r?/(«, but the black band upon the 

 discocellnlars still more triangular ; the black middle band of the cell docs not 

 e.xtend beyond the median nervure, as it does in aristeus, the submedian band 

 tapering behind. Hindwing, discal black band narrow, densely overshaded wiih 

 white in cell, its anterior jjortion ill-defined ; Mack marginal region in width 

 midway lietween (irixteus and jiarmatux, but ])osteriorly as black as in nrixtens. 

 Underside of the dark colour of arixteus ; hindwing as in tliis form, but white 

 discal area of forewiug wider. 



This Obi form is very interesting, as it combines the characters of aristeus and 

 parmatus. 



One THule only. 



3. Papilio tydeus obiensis subsp. nov. 



S. Upperside : band of forewing wider, es]iecially the two spots between veins 

 .") and 7 ; the first patch of the band of the hindwing before vein 7 narrower basally, 

 the black basal area penetrating well beyond the subcostal nervure, sometimes 

 nearly halfway to vein 8. Underside : band of forewing broader, and orange spots 

 of liindwing, esjjecially the posterior ones, much heavier, than in t'jdeus.
