1114 rilK BUTTERFLIES OF XK\V' i:\(.T,.\XI). 



Mr. Edwards lias a male wlioso f'litire expanse is but 28 nun. and a female whose ex- 

 panse is 30 mm. : I have a female whose fore wina; measures but Hi mm.; ami Arr. 

 Saunders sent me a male from Canada, the lenjrth of whose fore winj; was only 8 mm. I 

 The average size of individuals from the Mississippi valley is much greater than I 

 have seen from other places, the (J sometimes having a length of wing of 30 mm. and 

 the 9 of 33 mm., but such specimens do not occur in New England. They are also 

 never begrimed with griseous scales to the extent one finds the case in New England. 



Malformations. In a specimen before me one of the antennae is slightly mal- 

 formed, the .seventh and eighth joints from the tip (that is, just at the base of the club) 

 being divided by a strongly oblique suture, which has altered their shape, the two 

 together being not regularly cylindrical and scarcely longer than a single joint should 

 be; each joint is wedge-shaped, the proximal thrust a little out of linear place making 

 a distortion visible to the naked eye; it is apparently the lirst step toward a bifurca- 

 tion of the antennae, since it would require but little more distortion to permit a sec- 

 ond club to find support at the tip of the proximal joint. 



Aberrations. Mr. F. H. Sprague has shown me a male, taken at WoUaston, July 

 10, in which the discal spot of fore wing is double, both on the upper and under sur- 

 face, in which it distinctly imit.ates the homologous spot of the hind wing, the secon- 

 dary spot being above and smaller than the main spot and confluent with it; it sliows 

 above no trace of pale scales within it. but beneath has a transverse, partially conflu- 

 ent, pale bar consisting of mingled yellow, silvei\v, and ferruginous scales. 



A male taken November 10 at Bangor, Maine, by Mr. Carl Braun, is remarkable for liav- 

 ing .all the wings, especially the disc of the upper surface, shot with orange ; the orange, 

 though deep in color, is not of a solid character but more or less intermingled with nor- 

 mal yellow scales, giving a somewhat pink appearance. The insect indeed looks-as if 

 it had been kept too long in the cyanide bottle; but Mr. Braun assures me that it had 

 the same appearance while on the wing, causing him to capture it; the lateness of the 

 season of capture will be noted in this connection. The insect looks tolerably fresh 

 and possibly emerged from the chrysalis just before a sharp frost. 



Strecker states that he has a male specimen taken near Montreal in which tlic upper 

 surface is "dull dark green" with the usual border, and beneath dull green. 



Females are sometimes taken in which the spots in the marginal band of the fore 

 wings are either absent or so far removed toward its interior Ijorder as to leave the 

 same ragged. Sometimes also, both in this species and the ne.xt, the outer margin, in 

 either sex, may be dusted with yellow scales, sometimes confined to the front wing 

 sometimes common to both. The range of variation is well indicated by Edwards in 

 the second volume of his superb Butterflies of North America. 



EuRYMUs PHIL. NiGRiDicE. This name may be given to the sport rarely seen 

 which is figured by F^ldwards (Butt. N. Am., ii, pi. Colias 3, tigs. 8-!)) and by Glover in 

 his unpublished work (111. N. A. Lep., pi. I. fig. 5). Three .specimens were seen at 

 Palmyra, N. Y., by Mr. Worthington of Chicago but only one captured, and this is the 

 specimen that has been figured. It is a male, wholly smoky black above, but with a 

 pink fringe, and with the margin distinguished from the rest by a slight paleness, tlie 

 very opposite to what one would expect. The under side of the fore wings is 

 wholly smoky brown excepting the yellow tip, while the hind vi'ing is normal. Another 

 taken by Mr. Pearson near Montreal was described by him as "deep brownisli black* 

 above, "somewhat green tinted if seen ol>liquely. On the under side the primaries are 

 dark brown and secondaries almost olive green." Mr. J. G. Jack also captured another 

 specimen many years ago. in the same locality. 



A female in which the melanism has gone not nearly so far was taken at Faulkner, 

 Mass., July 29, 1883, by C. C. Bealeand figured by Maynard (Butt. N. E., pi. 7, flg. 57c). 

 In this the band of the hind wing is far broader than usual, but otherwise this wing 

 is normal ; while on the fore wing the basal half of the inner margin and some 

 parts of the disc above it retain the normal yellow. Mr. F. H. Sprague tells me that 

 Mr. Beale took in August another partially melanized female, which in this instance 

 was the more marked from its being one of tlie form E. phil. pallidice!
