PAPILIONINAE : PAPILIO POLYXENES. 



1355 



a black pupil in tlie centre, of vari.able size; fringe black, interrupted very broadly in 

 the interspaces with yellow lunules, which extend down either side of the tail, on the 

 inner .side nearly or quite half way to the tip. 



Beneath slightly lighter than above, especially the base of the hind wings, which are 

 delicately bnt decidedly suffused with a slight olivaceous tinge. The fore icings 

 exhibit an exact repetition of the markings of the upper surface, excepting that the 

 submarginal spots are slightly larger and a little paler, the independent spots and 

 streaks' are rather more distinct and extensive, and the extra-mesial row of spots, or at 

 least the lower ones, are faintly or even considerably suffused with orange; in the 

 female, these spots are nearly or quite as large and distinct as in the male, or much 

 more so than on the upper surface; between the two rows of spots a few pale yellow 

 scales are occasionally scattered in a delicate, feeble row; and in the uppermost broad 

 subcostal interspace, directly over the uppermost spot of the extra-mesial row, a clus- 

 ter of such scales may sometimes be seen. The same may be said of the hitid loings, 

 so far as the two rows of spots are concerned, with the following exceptions; the 

 male and female are alike in the character and extent of the mesial row, the female 

 bearing the same markings as the male ; in the female, however, the interior border 

 seldom extends within the outer limit of the cell, but there is usually a spot of greater 

 or less magnitude in the cell, at the extremity ; in both sexes these spots are bright 

 orange, the summits of the upper row edged with pale yellow, and they are separated 

 from each other a little more widely than on the upper surface ; the spots of the sub- 

 marginal row are scarcely lunular, but mostly transverse ovate, the upper four orange, 

 edged laterally with pale yellow, the others pale yellow, occasionally tinged slightly in 

 the centre with orange ; the anal spot is the same as aljove ; beyond the mesial row of 

 spots is a narrow, nearly uniform band of velvety black, following the irregularities 

 of the exterior border of the spots, and followed in each interspace by a powdery, 

 transverse or subtriangular cluster of brilliant blue scales, which change beyond to 

 those of a pale yellowish green color, scattered less profusely over nearly all the 

 space intervening between the previous markings and the submarginal spots ; occa- 

 sionally, and especially in the male, there are scarcely more green than blue scales ; 

 fringe as on the upper surface but paler, and each lunule infringes slightly upon the 

 wing itself. 



Abdomen black, with a laterodorsal row of pretty large, round, straw yellow 

 spots, one in the middle of each segment, largest in the middle, and decreasing in size 

 toward either end and especially toward the base; a lateral row of similar but equal 

 spots, and an infralateral row of smaller equal spots; the valves of the male dark 

 brown (35 :30), half as long again as broad, scarcely tumid, the lower border slightly 

 sinuate, the upper strongly arched, the tip i-oundly angled ; the armature consisting of 

 a straight rod, half as long as the clasp and parallel with its lower border, turned up- 

 ward at its extremity and supporting a thin, equal, straight and slender, horizontal 

 lamina, bearing short, pointed, triangular, closely crowded denticles.
