and two black edged, round spots in the cell, the upper generally much the larger, 

 next the tlrst divarication of the subcostal nervure, tlie loAver, sometimes entii'ely 

 obsolete, a little ■\vitliin the first divarication of the median nervure; beyond is a pre- 

 mesial curving roAv of live very une(|ual silvery spots, rounded internally and edged 

 on the same side with black; the first, in the costo-subcostal interspace, just over the 

 second divarication of tlie suI)costal nervure, crosses tl\e whole interspace and is 

 rudely semicircular; the second, in the upper subcostal interspace, is a small spot, 

 sometimes almost obsolete, just below the outer border of the first ; the third is largest, 

 irregular, occupies the whole extremity of the cell, throwing a detachment a short 

 distance beyond it, and is also bordered internally Avith Ijlack ; the fourth is a diag- 

 onally oval, pretty large patch in the medio-submedian interspace, a little below the 

 tirst divarication of the median nervure, edged witli black along tlie whole face tliat 

 looks toward the base of tlie abdomen; and tlie fiftli is a smaller, longitudinal streak 

 in the succeeding interspace beside the fourth; poAvdery, longitudinal streaks, 

 Avliich may be said to form a part of this series, occasionally occur at tlie extreme base 

 of the lower subcostal and median interspaces: the silvery spots of the extra-mesial 

 and submarginal series are precisely as in A. cybele, only the submarginal spots are 

 usually narrowly edged externally (sometimes also internally) Avith black instead of 

 cinnamoneous ; and the extra-mesial markings are foUoAved at their exterior tips by a 

 series of small, I'ound, more or less vague, deeply tinted, cinnamoneous spots, occa- 

 sionally narroAvly edged Avith buff in the female. BetAveen the tAvo outer series of 

 silvery spots there is an irregular narroAV bufl" belt, narroAver in the male than in the 

 female, its exterior border pretty distinct and zigzag, formed 1)y the interior edging 

 of the submarginal silvery spots, its interior border very vague, but generally con- 

 formable to the outer limits of the cinnamoneous spots at the apices of the extra- 

 mesial silvery spots ; the outer bordering of cinnamoneous is sometimes suffused along 

 the middle and especially on the loAver half of the Aving, Avith buff; fringe as in A. 

 cybele. 



Abdomen above and on tlie upper half of the sides black, covered profusely and 

 especially on the sides toAvard the apex, where they almost or quite supplant the 

 black, Avith orange fulvous scales, and on the basal half Avith fulvous hairs; below 

 uniform buff; hairs of the terminal segment fulvous. Appendages ; upper organ of 

 male : hook of equal depth throughout, the tip pretty strongly and delicately uncinate 

 solely by the excision of the under surface of the hook; clasps but little more than 

 tAvice as long as broad, the apical half curved a little upAvard, of nearly equal breadth 

 throughout ; upper border Avith a sliglit but rather abrupt rounded elcA^ation near the 

 base, a similar but not so regularly rounded middle one, Avhile the upper posterior 

 angle is produced to a broad rounded lobe, directed f orAvard and a little upAvard, larger 

 than any of the others ; posterior edge bent in the middle at a right angle, and a little 

 roundly produced at the angle ; upper pi'ocess similar to that of cybele, but slightly 

 smaller and not reaching the hinder extremity of the clasp. 



Secondary sexual peculiarities. The males differ from the females in the charac- 

 ter of the squamation of the front Aving, in exactly the same Avay as in A. cj'bele ; the 

 androconia (46 : 13), Avhich are seated on the aflected veins, are very similar, but dif- 

 fer from both the other New England species in being proportionally broader, and 

 having the apical feathered portion shorter; the same roAv of haii's is also found 

 above the subcostal nervnle of the hind Avings in the male, but in the present species 

 they are broAvnisli fulvous, instead of pale broAvii, as in A. cybele.
