422 THE BUTTEIU'LIES OF NJ:W ENGLAND. 



slightly !siiuiou.s course, acros.-; tliu ii!)i)cr lucdiau ncrvule ju.st within tlie limit of 

 its basal curve, to the inuer border at its excision ; its exterior niai-gin is pretty regu- 

 larly bowed, approaching the outer border at either end, and on the upper median 

 nervure lying scarcely more than midway from the interior border of the belt to the 

 tip of the dentation ; outer margin of the wing ornamented precisely as in the fore 

 wings, excepting that within it, small caerulean lunules are seated in the interspaces 

 upon the grayish stripe, their exterior margins straight, their interior curved, except- 

 ing in the medlo-submcdian interspace, Avhcre they are transversely linear, always 

 widely separated from each other; occasionally they are very minute. Fringe as in 

 fore Avings. 



Beneath, darlv bluish, slate brown, the fore wings generally a little duller than the 

 hind wings, the limits of the belt much as above but only distinct next the inner border. 

 Fore icings Avith the costal border streaked with transverse black bars which do not 

 reach the nervure excepting next the base ; the cell is crossed by two zigzag, transverse, 

 black lines, one nniting the first branches of the subcostal and median ncrvures, the 

 other parallel to it a short distance Avithin ; further toAvard the base there is an oblique, 

 longitudinal, oval, black loop seated on the median nervure close to the base and pro- 

 jecting into the cell: and the apical portion of the cell, Avhich is grayer than the rest 

 of the base, is traversed by many inconspicuous curved threads of blackish scales; the 

 interior margin of the extra-mesial belt is limited also by a black line over portions of 

 its course, especially above and beloAV and there are other short, black streaks next the 

 upper outer margin of the cell ; the portion occupied above by the belt is gi-ayish, 

 auide up of a mixture of broAvnish scales of various shades from pallid to ferruginous, 

 l)ut is coursed throughout by transverse, blackish and dusky threads; the spot depend- 

 ing from the costal bortler is very inconspicuous and the outer border of the Ijelt very 

 obscure, but very frc(iuently thei'e is a slender, brownish fuliginous streak running 

 from its upper outer limit to the centre of the belt and then continuing doAvn its 

 middle; the outer mai'gin is similar to the upper Init darker and enli\'ened at the same 

 time Avith lilaceous scales, and the slender, blackish stripe Avhich borders it interiorly 

 is nearly hidden by a series of continuous, slender, scarcely curving, pale caerulean 

 lunules ; the fringe is cupreous blue, tipped in the interspaces Avith Avhitish. Jlind tviiu/s 

 Avith the belt better marked, its inner border conspicuous by the distinct black edging 

 throughout its course ; Avithin this there is a second broken, equally slender, transverse, 

 black stripe; it crosses the costo-subcostal interspace diagonally. midAvay betAveen the 

 base and the outer black stripe, touching the subcostal just Avithin its first divarica- 

 tion; it crosses the cell in a slight outward curve, connecting^the bases of the first 

 l^ranches of the subcostal and median, and the medio-submedian interspace a little Avithin 

 the first divarication of the median ; Avithin this series of transverse stripes the Aving is 

 dark grayish broAvn, Avith basal and subbasal patches of bluish slate broAvn, and traversed 

 by numerous, short, transverse threads of blackish; the belt is much as in the fore 

 Avings, but is more uniform and sIioavs darker broAvn, faint spots fomning an obscure 

 transverse series in the middle of the outer two-thirds. Fringe as in fore Avings. 



Abdomen above black, covered next the base Avith broAvnish hairs; beneath, slate 

 gray, darker toAvai'd the base; appendages of male (33 : 2.5, 2(!) : upper\)rgan; body 

 almost tAvicc as broad as long ; hook nearly straight, compressed, rapidly tapering, Avith 

 straight sides on basal half, slightly depressed on apical half so as to be a little ovate 

 from a superior view, bluntly pointed. Clasps fully twice as long as broad, of ecpial 

 breadth on the basal half; beyond tapering a little and on the apical [foui-th rapidly, 

 the upper hinder angle very slightly produced and incurved ; upper basal appendages 

 compressed, nearly five times as long as the breadth of base, narroAvlng very slightly 

 just beyond the base and then suddenly expanding at the upper edge to tAvice the 

 height, forming a rounded lobe, more abimpt posteriorly than anteriorly, as high as 

 broad, inclined a little backward; beyond this it tapers to a point and curves pretty 

 strongly iuAvai'ds, having previously had only a backAvard direction; interior needle 

 pretty In'oad, on basal half compressed ; beyond tapering to a point, a little arched and 

 reaching close to the tip of the clasp.
