PAPILIONIDAE : PAPILIONINAE. 1847 



lower part of the cell; ia the slender, subcostal Interspaces between this spot ami the 

 outer upper spot of the extra-mesial series there are slender streaks of yellow followed 

 in the penultimate, superior, subcostal interspace by a large, triangular, yellow spot, 

 midway between the base of the interspace and the spot beyond ; the general tone of 

 the ground in the outer half of the wiug is slightly darker than in the basal half; there 

 are a few greenish yellow scales flecking the costo-subcostal interspace faintly above 

 the apical half or more of the cell. Hind wings : the ground of the outer half of the 

 wing is black, in more marked contrast with that of the base than on the fore wings; 

 the submarginal series of spots consists of transverse, luuulate bars crossing almost 

 the entire interspace, subparallel to the outer margin of the same interspace with the 

 exception of that in the costo-subcostal interspace which is rather subparallel to the 

 other spots; the spots of the extra-mesial band are completely confluent into a band, 

 barely, if at all, interrupted by the nervures ; it is moderately slender with regular, 

 arcuate, interior margin, somewhat powdery, especially in the middle of its course, 

 usually broader in the male than in the female, and somewhat irregular in its direction, 

 its interior border in some cases crossing the wing at the apex of the cell, at other 

 times beyond it by the entire width of an interspace (which is ordinarily the course in 

 the female), and at others, at least in some males, including the tip of the cell in the 

 band, in which case the outer limits of the cell are marked in black; the exterior mar- 

 gin of this belt is clearly marked in the upper part of the wing, passing in a series of 

 strong arcuations as far as the middle of the wing; below which the limit of the band 

 is more regular but obscured by a heavy powdery of greenish yellow scales which 

 cover the greater portion of the median interspaces beyond the band, including by 

 their absence obscure, black spots in the middle of the interspaces, directly following 

 the band and which are seated upon vague, powdery spots of blue scales, extending as 

 a faint band of lunules across the entire wing, generally subobsolete and found only in 

 the female; the anal angle is occupied by a large, black spot which is in continuation 

 of the black spots of the preceding interspaces, including within it a large, blue, 

 powdery lunule, followed behind in both sexes, and in front always in the female, 

 sometimes in the male, by orange, which on the inner side infringes upon the yellow 

 extra-mesial band ; at the extremity of all the interspaces the dark fringe is inter- 

 rupted by yellow which extends as a distinct lunule upon the ground of the wing 

 itself. 



Beneath, with the ground color a little paler than above ; the /ore inings with the same 

 markings as above, slightly enlarged and with the transverse bar at the end of the cell 

 distinct in both sexes ; in addition there is a vague, powdery, straight, oblique stripe 

 crossing the base of the wing and especially of the cell , which is in continuation , when the 

 wings are spread , of a more distinct stripe which vrill be described upon the hind wings ; 

 this is always more distinct in the male than in the female, and is occasionally wholly 

 absent from the latter. Hind loings with the basal half uniform, excepting for a 

 deepening at the extreme base of the wing and for a yellow edging to the basal lobe 

 previous to the tip of the precostal and a straight, or slightly arcuate, narrow yellow 

 streak, broader above than below, which runs from the costal margin where it is 

 sometimes paler, nearly to the middle of the first median nervule, following down this 

 latter along its inner edge ; the outer half of the wing is much variegated, the marginal 

 lunules in the interspace are more distinct than above and are almost white ; the sub- 

 marginal series of lunules are also more highly developed but are pale orange with white 

 ends, and that which occurs in the medio-submedian interspace is united with the 

 marginal marking, showing its compound nature by the deep indentation of its inner 

 side ; the mesial baud has become a series of closely adjoining, but distinct white 

 lunules, heavily marked with orange, so as in many cases, especially in the female, to 

 be more orange than white, but always white along the inner margin and here inva- 

 riably removed farther toward the apex of the wing, never including the cell, although 

 occasionally touching it in the male ; they are margined externally with round, deep, 

 black spots, including in each interspace a powdery spot which leaves only a lunulate 

 black edging to the extra-mesial band ; the powdery spot is more dense toward the
