324 THE BUTTERFLIES OF NEW ENGLAND. 



outer border scarcely crenulate. The coloration of the upper surface of the fore 

 wings cliflers in no respect from that of fabricii, excepting that the cinnamoneous 

 tints of the outer half of the wing are deeper and often infuscated, and that the outer 

 border shows scarcely any of the bloom, the tips of the nervules only having a few 

 scattered bluish scales about them. Hind wings with the outer border (61 : 17) very 

 slightly crenulate, the tail of the upper median nervule about half as long again as 

 broad, the sides nearly parallel; the projection at the tip of the upper subcostal ner- 

 vule slight and broadly rounded, that at the lower angle inconspicuous. These wings 

 differ from those of the form fabricii much as the fore wings do, the parts which in 

 fabricii were cinnamoneous becoming almost uniformly black and completely obliterat- 

 ing the submarginal spots ; except faint traces sometimes seen near the costal margin ; 

 the fulvous portions also become deeper and so much less conspicuous ; the bloom is 

 not so nearly obsolete as on the fore wings, but excepting the tail, the outer boi-der 

 is much more narrowly margined than in the other form. 



Beneath, the difference is more multiform, the general color of the wings of the 

 5 being of a dull, dingy yellow brown with a slight olivaceous tinge, and more or less 

 covered with a most delicate pale bluish bloom, not so intense as that bordering the 

 outer margin of the upper surface, but much more noticeable than in the same sex of 

 fabricii; the markings have the same localization as in that form, but they are more 

 distinct and deeper than there, approximating those of the J of fabricii, while the 

 contrasts are scarcely greater than in tlie $ of the same form ; the row of dots in 

 the outer half of the wings is more distinct, indeed could hardly be overlooked by a 

 casual describer, while they would scarcely be seen without search in the same sex of 

 fabricii; they are even more noticeable than in the ^ of fabricii; on the hind Avings, 

 where the glaucous tinge is more marked, this bloom is wanting in the double or 

 broken transverse band, described in the J of fabricii as accompanying and enclosing 

 the transverse series of black dots ; and tinally, occupying the position of the hoary 

 dots described as lying in fabricii midAvay between the black dots, and the outer border 

 of all the wings, there is a faint, submarginal, often broken or partially obsolete, strongly 

 crenulate streak of blue greenish atoms, receding from the border in the middle of 

 the interspaces, more distinct and connected in the hind than in the fore wings, and 

 never passing above the dentated portion of the fore wings. 



In the ^ the differences are of a similar character; the general tint of the wings is 

 lighter than in fabricii, being of an ochraceous clay brown, the darker markings of 

 the base of the Avings being located precisely as in fabricii and scarcely deeper in tint, 

 the greater contrasts in the wing being attained by the additional paleness of the 

 lighter markings ; the transverse row of dots in the onter half of the wing here attains 

 its maximum, becoming almost conspicuous in the fore wings, and in the liind wings 

 quite conspicuous, because the ferruginous bands in which they occur become developed 

 as pretty large, approximated, round, ferruginous spots, especially in the lower subcostal, 

 the median and medio-submediau interspaces, in which smaller, dull, olivaceo-f ulvous 

 spots are enclosed, having the black dots as their pupils; the hoary bloom of the 

 wings is not so conspicuous as in the $ , but is more distinct than in the ^ of fabricii, 

 and most noticeable on either side of the bands enclosing the dots on the hind wings 

 and in the middle of the outer border of both wings ; the submarginal crenulate line of 

 blue-green scales is more distinct and continuous than in the other sex and indistinctly 

 edged with black ; it does not extend above the middle subcostal nervule of the hind 

 wing or above the falcation of the fore wing; within these same limits there is close 

 to the outer edge of the wing a delicate cinnamoneous thread, parallel to the outer 

 border, sometimes infuscated. 



The contrasts are also greater between the paler and darker markings of the fringe 

 in both sexes and on both surfaces of umbrosa than in fabricii, and in the specimens I 

 have examined there is in umbrosa an occasional absence of the silver dot outside the 

 silver comma of the under side of the hind wings, wliich I have never seen to fail 

 in fabricii.
