which is continued round by anal angle, forming a submarginal 

 stripe, to apex, whence it forms a curve as far as discoidal 

 nervure ; a silver ^-shaped mark between second median and 

 discoidal nervule, the bases nearly resting on submarginal stripe ; a 

 subcrescent-shaped silver stripe near anal angle divided by first 

 median nervule ; four small square black confluent spots just above 

 submarginal stripe, between discoidal and second subcostal nervules ; 

 above these, two ochreous lunules bordered above, as far as outer 

 edge of silvery curved band, by a large black irregularly-shaped 

 blotch; space between arms of y^-shaped mark, and inner edge of 

 submarginal stripe between second median nervule and submedian 

 nervure, deep chestnut ; a large black lunular spot between first 

 and second median nervules, its inner edge touching the subcrescent- 

 shaped silver stripe. Thorax reddish brown ; some bluish-green 

 hairs on collar and between eyes ; eyes dark reddish browu, bright

Papilio xenophilus, n. sp. 



Mule. — Upperstde dark brown : primaries — a straw-coloured 

 transverse marginal band slightly curved inwards towards the apex, 

 straight on the outer edge and nearly parallel with hind margin, 

 rather clouded on inner edge ; nervures crossing band dark brown 

 and clouded at their edges : secondaries tailed, scolloped ; a straw- 

 coloured transverse and somewhat outwardly dentated band from 

 costa, near apex, to inner margin just above anal spot ; anal spot

 indentations whitish. I'nderside : primaries, same as above but 

 band paler : seco?idaries, no band, but instead a series of seven 

 whitish-yellow spots, the three near anal angle and one at apex near 

 costa small and indistinct, the other three large and oblong-oval ; 

 beyond these spots patches of bluish atoms ; a marginal row of 

 indistinct orange-yellow spots, above each of which is a cloudy

This species comes near P. capaneus, Westw,, but differs in 

 having the bands right across the wings, and in the markings of the

Papilio erskinei, n. sp. (Plate XXXIV. fig. 1.) 



Male. — XJpperside ^xeem&h black : primaries With a marginal band 

 of eiglit large creamy-yellow spots curved inwards at the apex, 

 extending from subcostal to submedian nervure, and with indications 

 of another spot between submedian nervure and inner margin, and a 

 short dash of the same colour between the subcostal nervure and 

 costa, and just above the subcostal spot ; base of cell dusted with a
