THE BUTTERFLIES OF NEW ENGLAND. 



■white, the inner the less distinctly. The submarginal liinules of the upper surface, 

 both yellow and bine, are repeated beneatli but more conspicuously, the yellow lunules 

 usually extending to the border, and followed above in each interspace Ijy a similar 

 transverse bar. which unites itself more or less distinctly to the lunule of the inter- 

 space above, with which it is nearly or quite aligned; in the upper median interspace, 

 however, it is formed of powdery yellow scales; the blue lunules, though powdery, 

 are much more distinct than above, and are usually edged above with hoary; and 

 these too, are surmounted at a short distance by strongly bowed, powdery lunules of 

 pale yellowish green, that of the lower median interspace corresponding to that above, 

 and lilie it united to a yellow spot at the angle of the excavated inner border. Midway 

 between the inner carmine spot and the extremity of its interspace is a delicate trans- 

 verse bar of blue scales ; the powdering of the median area is more diftused and scat- 

 tered than above, and the hoary bordering of the tails seldom extends more than half 

 way toward their base; the costal edge is clay yellow at the summit of the outer pale 

 band ; the markings of the outer edge find the fringe are as above. 



Abdomen black, the sides with a broad, superior, longitudinal, whitish stripe and a 

 narrower inferior one, united to the upper on the last segment, but immediately pre 

 vious to that broadened and divided longitudinally in halves, by a slender black line, 

 which crosses four or Ave segments ; the black band between the upper and lower pale 

 lateral bands is continuous with the black tlioracic band which hugs the base of the 

 wings beneath. Clasps of male (35 : 26-29) yellowish white, edged with lilack, the 

 denticulate ridge parallel to outer margin slight, the denticles line and small, above 

 connected with a horizontal, thin, high and straight lamina, running toward the upper 

 base, itself denticulate on the inner edge; from near the connection of the two, and 

 supported by the latter, springs a slightly down-curved, long and tapering spine, 

 directed toward its fellow on the opposite valve ; while at the lower extremity of the 

 arcuate denticulate ridge arises a thin and slight, vertical, triangular, pointed lamina.
