Pap ilio e > -ith o n io ides. 



Male. — Upperside. Both wings with markings as in de- 

 moleus, Linn., but on the posterior wings the stramineous 

 band which crosses the wings before the middle is broader 

 and the spots in the submarginal row are more lunulate ; at 

 the lower end of the dark rufous spot above the anal angle is 

 a large subovate black spot, the middle median nervule is 

 produced into a short tail rather more elongate than in 

 demoleus. 



Underside approaches nearer to P. erithonius than P. demoleus, 

 but the anterior wings are more irrorated with stramineous 

 scales, and on the posterior wings the central band is less 

 rufous and broader than in erithonius ; the curved black line 

 which crosses the cell of that species towards its end is 

 represented in erithonioides by a triangular black spot with 

 the apex pointing outwards, and the irregular row of black 

 bars which divides the central band is wider ; the veins on 

 the disk are black instead of stramineous, the ocellus below 

 the costal nervure is larger ; and at the anal angle, instead 

 of the ferruginous spot crowned with a black spot centred 

 with blue scales, is a dark rufous spot, with the black spot at 

 its lower end as on the upperside, above which is a round 

 black spot with a blue iris centred with brown. The sub- 

 marginal lunules are more deeply incised outwardly. 



Female. — Upperside. Both wings resemble the male, but on 

 the posterior wings a space on each side of the large ocellus 

 below the costal nervure is bright ferruginous ; on the disk 

 the space between the stramineous band and the row of sub- 

 marginal lunules is brightly irrorated with stramineous 

 scales, in which, between the veins, are spaces less densely 

 irrorated with the same colour, giving the appearance of 

 indistinct black spots, with clusters of blue scales more or 

 less distinct below each, resembling somewhat the mottled 

 appearance of the posterior wings of Opliidocejjhalus, Oberth. 

 The lunules in the submarginal row are very strongly deve- 

 loped, the apices of each lunule being elongated towards the 

 margin ; the tail formed by the prolongation of the middle 

 median nervule is very marked, being nearly ^ inch long. 



Underside. All the spots on both wings larger than on the 

 upperside. Anterior wings with the first four of the sub-
