NORTH AMERICAN BUTTERFLIES. 31 



Female, brighter, more orange above, with marginal dots on fore 

 ■wings, enlarged and connected by rosy rufous edges, as are the smaller 

 ones on the hind wings. At end of central coll, and without it, is a 

 small brown spot, and beneath it, without and within the cell, is a brown- 

 ringed, orange spot. The hind wings show indications of the spots on 

 end of central cell beneath. Beneath, there is a cluster of narrowly 

 brown-ringed, silver spots, overlaid with red, at end of central cell of 

 fore wing, and both spots on hind wings are always silver-centered, and 

 a distinct bar passes outside of them. The rufous bandings are more 

 prominent and there are several others on the hind wings. An exceed- 

 ingly variable species, some of both sexes being much more orange tint- 

 ed than others, with bandings exceedingly variable, and sometimes both 

 sexes are sprinkled beneath with rufous. Expands from 2.00 to 2.7.j. 



Habitat, Southern States, north to Virginia, Ohio, and Ills., casu- 

 ally to New York and Rhode Island, and also Arizona and Southern 

 California. 



55. CALLIDRYAS SENNAE Linn. 



YELLO\y-GREEN BUTTERFLY. 



Male differs from C. eubule, in being of a clearer, more greenish, 

 yellow on both surfaces, l)ut more especially below. There are no black 

 scales at end of central cell above on fore wings, and little or no indica- 

 tions of any marginal points. There is usually only one silver spot at 

 end of central cell of hind wings ; this is smaller and the edging is pale 

 rosy rufous. The rufous bandings are mostly absent, or at best, only 

 faintly indicated ; but the most positive point of difference, may be seen 

 in the spot at end of central cell of fore wings, this being reduced to a 

 rosy-rufous, oval spot lying on the cross vein, compare Fig. 15, f, upper 

 with ib. f, lower The female is dull, orange yellow above and below, 

 with all the markings rosy rufous, especially noticeable on the fore wings 

 above and below, this often being witliout any silver center; infact, the 

 silver center, when present, on both surfaces is so strongly overwashed 

 with rufous as to be nearly obsolete. The positive point of difference, 

 however, is seen in this spotting below at end of central cell of fore 

 wing. In this species, the spots are two only, that is, undivided by any 

 decided lines or edging, compare Fig. 15, f, lower, eubule witli ib., f, 

 upper, sennac. Expands, 2.00 to 2.75. 



Habitat, Central and Southern Florida, and Texas and Arizona. 

 This and the preceding species occur from March to November in Flor- 

 ida.
