PaPILIO NlTRA. 



Belongs to the Asierias group, and stands next Indra ; costal mar- 

 gins of primaries in both sexes much bent near apex ; hind margins in 

 both convex ; tails long, narrow, tapering ; the two sexes alike in mark- 

 ings. 



Male. — Expands 3 inches. 



Upper side black, spotted and banded with light yellow, the sub- 

 margmal spots of primaries rounded next apex, the rest ovate ; of sec- 

 ondaries semi-circular, the two next inner margin lunate ; the discal 

 band composed of separated spots, which are long, the upper 5 lanceo- 

 late, the others truncated, and not clearly defiaed on basal side ; these 

 spots resemble in shape the corresponding spots in P. Bairdii, but all 

 are square-edged on outer side ; on secondaries the band is also com- 

 posed of separated spots, and covers about one-fourth the cell ; above 

 the incision at anal angle is a pale orange ring on yellow ground, in-« 

 closing a round, black spot ; on the black ground beyond the band are 

 loose clusters of blue scales entirely across the wing, those next inner 

 margin scarcely more dense than elsewhere. Under side pale black, 

 the markings repeated, pale ; the extra-discal area on secondaries 

 dusted lightly with yellow scales, and above them blue scales about a 

 rather dense nucleus in each interspace. On the spot at outer angle 

 is a faint tint of orange, and so also on the outer end of the two spots 

 of the band in median interspaces ; the anal ring deep orange ful- 

 vous. 



Body black, the wing covers all yellow ; the abdomen wholly* black, 

 except for a slight lateral stripe ; legs black; palpi black; frontal hairs 

 black, at the sides yellow; antennae and club black. 



Female. — Expands 3.3 inch. 



Spotted and banded like the male, but the five upper spots of the 

 band on primaries are sub-ovate; the yellow throughout is paler; under 

 side without orange, except in median interspaces. 



From a singl-e pair taken in Judith Mtns. Mr. Courtis wrote me that 



* In the description of Indra, Part VII. vol. 2. But., at bottom of first page, for 

 " the abdomen white without yellow," it should read " the abdomen wholly without," 

 &c.
