1786 BUTTERFLIES BEYOND NEW ENGLAND. 



It differs from N. areolatus in its darker upper surface, but most markedly iu the 

 form of tlie extra-mesial spots and in the oval enclosure of both wings, the former of 

 ■which are here circular or almost circular, while in areolatus they are very elongated in 

 the direction of the interspaces. 



This buttei-fly was first described since the publication of the first part of 

 the present work, and nothing is known of its early stages nor of its dis- 

 tribution beyond that it was found in southern Michigan by Prof. J. N. 

 Mitchell, who thinks that it occurs also in central Michigan. It was 

 taken in dry upland meadows, and doubtless will be found over a con- 

 siderable extent of territory in the near future.

Imago. Head covered with long, erect, brown and pale hairs and scales, the paler 

 ones external to all masses; the palpi with white or yellowish white scales upon the 

 sides, brownish black scales upon the upper surface and a heavy fringe of mingled 

 black and white scale-hairs; antennae dark brownish luteous, the joints basally annu- 

 late or subannulate with white ; the club almost entirely naked, fulvo-luteous below, 

 fusco-luteous above. 



The upper surface of the wings is uniform rich dark slate brown, the outer margin 

 of all the wings marked with a Ijlack thread preceded by a more or less obscure nar- 

 row pallid stripe, more distinct upon the hind wings than the fore wings, limited inte- 

 riorly, especi.illy upon the lower portion of the hind wings, by a similar Ijlack thread ; 

 basal half of the foi-c wings in the male heavily covered with moderately long, delicate, 

 blackish hairs, partially concealing raised scales which broadly border the basal half 

 of the first median nervule and are found to some extent also in the lower portion of 

 the cell. 



Under surface pale slate brown rendered moi-e or less grayish by a scattering of dull 

 yellow scales ; both wings crossed by two distinct transverse threads of brownish 

 fuliginous, subparallel to the outer border, slightly tremulous but nearly straiglit, 

 though more or less sinuous in the lower half of the hind wings ; the inner crosses 

 the wing somewhat further within the apex of the cell than the other is outside of 

 it, .and the outer is a little less than midway from the inner thread to the outer 

 border ; the outer border edged with black is preceded by a brownish fuliginous, straight 

 line Ijarely separated from the outer by a clay yellow thread, and preceded by a sinuous, 

 sublunulate, but otherwise similar thread ; in the belt between the last and the extra- 

 mesial thread is found on both wings a series of small, distinct annuli ; these vary iu 

 distinctness and importance in different parts of the wings and in different individuals ; 

 on the fore wings the most important is in the lower inferior subcostal interspace and 

 is blackish brown, nacreous-pupiled and with a pale, dirty yellow areola; the others in 

 the interspace above and the succeeding interspaces as far as the lowest median nerv- 

 ule, are even at their best rarely pupiled, with a spot generally reduced to fuliginous 

 brown, the areola enlarged at the expense of the interior spot and itself bordered nar- 

 rowly by brownish fuliginous; on the hind wings the ocelli are more distinct and more 

 brilliant, the most distinct and largest being those in the lowest subcostal and lowest 

 median interspaces, where they are a rich blackish brown with a bluish nacreous pupil
