THE BUTTERFLIES OF NEW ENGLAND. 



Beneath, the wings are dark lustrous purplish blue, generally tinged strongly in part 

 with greenish, especially in the cell, obscured in places, and especially in the inter- 

 spaces of the hind wings, with tints varying from dark olivaceous brown through dingy 

 snufl" color to obscure tawny or even dull orange, flecked with dark brown, most dis- 

 tinctly in the female ; the nervures always blue black. Fore loings : The whitish streak 

 near the middle of the costal margin of the iipper surface is repeated beneath, and the 

 apex of the wing from the middle of this to the middle of the central median nervule 

 and extending as far as the submarginal markings is olivaceous slate brown, enlivened 

 with a few tawny atoms. In the centre of the cell is a roundish, at the extremity of 

 the cell a long, transverse, bright reddish, orange spot, broadly encircled Avith velvety 

 black; on either side of the first, bordering the subcostal nervui'e, is a small delicate 

 pale blue patch, the outer the smaller; there is a submarginal, double row of pale blue 

 transverse stripes, a pair in each interspace, the inner row more curved and slightly 

 paler, the outer slightly broken in the middle of each interspace ; these are followed 

 interiorly by a row of quadrate, pale, rusty orange spots in the median and most of 

 the subcostal interspaces, corresponding to those sometimes appearing above; and 

 these again, on the upper half of the wing, by some unequal whitish spots, correspond- 

 ing again to those on the upper surface and often, as there, extending faintly on the 

 lower interspaces; there is a streak of dull orange on the costal margin next the base 

 of the wing ; fringe as above. The hind wings have three little patches of scattered 

 blue scales at the base of the wing, one enclosed in the curve of the precostal uervure, 

 one at the divarication of the costal and subcostal nervures, and one at the base of the 

 cell; costal margin at base broadly bordered with reddish orange; three large, round- 

 ish, bright reddish orange spots, bordered rather broadly with velvety black in the 

 basal portion of the wing, viz. : one oblique oval spot at the base of the costo-subcostal 

 interspace next the blue spot ; one roundish, or transversely oval, slightly larger spot 

 at the base of the cell just beyond the blue spot; and an oblique, transverse, quadrate 

 spot in the cell, separated from the preceding by a considerable space, more or less 

 filled with bluish or greenish scales. There is a double row of submarginal bluish 

 spots next the outer border, similar to those of the fore wings, only of equal depth 

 of tint ; these are followed by a regular row of nearly equal, roundish or semicircular, 

 orange spots, the lower one transverse, bordered very broadly below, to a less extent 

 above, with velvety black; upon the upper black margin of these spots is seated a 

 collection of somewhat scattered, rather pale blue or greenish blue scales with some 

 intermiugled blackish scales ; fringe as on the upper surface. 



Abdomen above blue black; on the sides the same, with a slender, median, Avliite 

 line; below the same also, the middle half of the segments edged posteriorly with 

 white, narrowly in the female, broadly and sometimes coalescentin the male. Appen- 

 dages of the male (33 : 15) : upper organ ; hook regularly and gently curved througli- 

 out, equal in height until the tip is reached, which tapers rapidly to a point and is 

 excised beneath. Clasps very nearly three times as long as broad, beyond the promi- 

 nence of the lower edge tapering rather rapidly and regularly to a somewhat broad, 

 rounded apex, but with a prominent extension of the upper border a little before the 

 middle of the free portion ; this extension is twice as long as high, one-half as long as 

 the breadth of the clasp ; apex of clasp not one-third so broad as the base and Avith 

 the apical portion of lower edge armed with six or eight small pointed spines ; interior 

 finger much as in B. archippus but not so roughly beset Avith prickles, a little pointed 

 at the tip, and the extremity mostly hidden by tlie prominence of tlie upper edge of the 

 clasp.
