XVIT. — Descriptions of Tioo new Forms of Papillo in the 

 Collection of Mr. Grose- Smith. By H. GrOSE-Smith, 

 B.A., F.E.S., F.Z.S., &c. 



Papilio pando.vus. 



Male. — Upperside. Black as in P. pandion, Feld., with the 

 grey rays on the anterior wings towards the apex less pro- 

 nounced. Posterior wings with a lemon-yellow band in place 

 of the white band of P. pandion, a Immlar mark of blue 

 scales above the anal angle, and indistinct markings of grey 

 scales beneath the band between the median nervules. 



Underside. Anterior wings as in P.pandion,hMi the apical 

 grey rays rather shorter. Posterior wings with band of 

 markings on the disk as in P. pandion, the upper row of 

 lunules yellow ; a yellow indistinct bar between the first and 

 second median nervules, about halfway between the band 

 and the outer margin. 



Expanse of wings 5-^ inches. 



Ilab. Astrolabe Bay, German New Guinea. 



Described from two specimens ; in the posterior wings of 

 the second specimen there are no grey scales beneath the band 

 on the upperside, and the bar towards the anal angle is 

 represented by a minute spot of yellow scales. 



Parnassius nivalis. 



Male. — Upperside. Anterior wings white, devoid of scales 

 at the apex and along the outer margin ; a broad irregular 

 grey band from a little beyond the middle of the costal 

 margin, extending across the wings to a little below the third 

 median nervule. Posterior wings with a minute grey spot 

 about the middle of the costal margin, a black spot at the 

 end of the cell, smaller than in P. nubilosus^ Ohristoph., and 

 a grey bar across the wings from the second median nervule, 

 where it is narrow, becoming broader on the first median 

 nervule and thence to the inner margin ; the base and basal 

 portion of the inner margin densely covered with grey scales^ 

 but not reaching the grey bar. The veins on both wings 

 across the disk are white, the ends of which towards the cell 

 and the median nervure are black. 



Underside as above, but all the veins are black. 



Expanse of wings 2f inches. 



Hah. Tsian Shan, Turkestan. 



The specimen was a single one among a large number of 

 P. nuhilosus. It appears to be intermediate between 

 P. mnemosyne^ Linn., and P. felderiy Brem.
