longitudinally oval, excepting the sixth, whicli is roundish and the seventh, which is 

 irregularly transverse; the middle one is smallest and the seventh, which is double, is 

 scarcely larger; the I'estare nearly equal, occupying about three-quarters the width of 

 their interspaces ; the inner edges of the first four si)ots run in nearly a straight line 

 from the middle of the costal border to the middle of the upper median interspace at 

 the outer border; the ceutres of the fourth, (ifth and sixth follow a straight line 

 drawn between two points a little way above the tips of the internal and upper sub- 

 costal nervures; the interior border of the seventh is on a line with the exterior of the 

 sixth. The outer margin is bordered much as in the fore wings and is followed by a 

 series of seven large, subtriangular, silvery spots, each as broad as an interspace, and 

 situated in the same interspace as those of the extra-mesial row, bordered with cinna- 

 moneous ; the whole space between this series and the extra-mesial forms a broad buff 

 belt — a cliaracteristic mark of the species, traversed by ciunamoneous veins and upon 

 which the extra-mesial row of silvery spots infringe ; fringe as on the fore wings. 



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

 with orange fulvous scales and on the basal lialf Avith fulvous hairs; below uniform 

 dull buff. Appendages of male (33 : 44) ; upper organ : hook deeper just before the tip 

 than elsewliere, the tip pretty sti'ongly and delicately uncinate, solely by the excision 

 of the xmder surface of the hook; clasps more than twice as long as broad, nearly 

 equal throughout, upper border with a slight rounded elevation near the base, a 

 larger, rounded, incurved one above the lower base of the upper process, and the upper 

 apical one small, similar to the extremity of the clasp, but directed forward and a 

 little upward, and covered with bristly hairs ; upper process equal, excepting at the 

 tip, which is slightly expanded, obliquely docked, or a little excised, the upper hinder 

 angle produced so as to make the whole nearly four times as long as broad, and to 

 reach as far as the hinder border of the clasp, the posterior edge minutely and 

 reversely denticulate. 



Described from 13 5 , 27 9 . 



Specimens from the south are much larger and duskier than the New England speci- 

 mens described above. I have received from Mr. W. H. lidwards a number of West 

 Virginian specimens whose fore wings measure 46 mm. Mr. F. H. Sprague has 

 shown me some very small specimens, captured at Mt. Tom, Mass., which he says are 

 of tlie size usually taken there. 



Aberrations. A. c. baal (^l. cybele abb. a, baal, Strecker, Cat. amer. macrolep., 

 HI). Mr. Strecker thus desciibes a suffused male in his collection : " Upper surface 

 primaries, submarginal lunules confluent with the row of round black spots interior 

 to them. Secondaries, submarginal line wanting, submarginal lunules connected and 

 suffused, forming an irregular jagged line; the roAv of spots interior to this almost 

 obsolete, other marks suftused. Under surface primaries, all black marks increased 

 and more or less confluent. Secondaries, over one-third of Aving (basal pai't) silver, 

 rest reddish brown, paler towards exterior margin; an irregular, rather broad, sub- 

 marginal band formed of confluent silver lunules and spots." 



Accessory sexual peculiarities. The males difler from the females in the neura- 

 tion of the front wing, as noted above, and in having on the upper surface of the 

 same wings a narrow series of diagonally disposed grayish brown scales on the 

 middle two-thirds of the submedian and lower median nervules, and on the basal 

 three-fifths of the upper two median nervules. These conceal tlie androconia (46 : 12) , 

 which closely resemble those of A. atlantis, except in being proportionally longer and 

 perhaps apically slenderer, and are considerably slenderer than those of A. aphrodite;
