28 LEPIDOPTERA OF NORTH AMERICA. 



The primaries have a large black point at the extremity of the 

 discoidal cellule, and a wide border of the same color, sinuated 

 interiorly, a little dilated at the summit, and divided at this part 

 by fine yellow nervures; the secondaries have on the disk an orange 

 spot, and at the extremity a black border following that on the 

 primaries, more or less sinuated within, and terminating in a point 

 a little before the anal angle. 



Under side of the primaries differs from the upper in being a 

 little more pale ; all the part corresponding to the border is 

 yellowish green, preceded by a transverse line of points, of which 

 the three inferior are black, and the others ferruginous and 

 smaller. 



The under side of the secondaries is yellowish green, with two 

 geminate, discoidal, silvery points, bordered with ferruginous cor- 

 responding to the orange spot, of which the outer is the smaller ; 

 besides this, there is a reddish line at the base, on the insertion of 

 the median nerve ; a small ferruginous spot on the costal edge, 

 followed by a transverse line of ferruginous points in a line with 

 those of the primaries. 



The fringe of all the wings is yellow, interrupted with brown 

 above and rosy below. 



Body yellow greenish ; back black ; antennae and feet rosy. 



The female differs from the male in having the border divided 

 by a yellow band, macular, interrupted on the primaries. 



Larva, which feeds on Trifolium, is green, with a lateral ray 

 mingled with white and yellow, marked with a fulvous point on 

 each ring. 



Chrysalis green, with a lateral yellow line and some ferruginous 

 points. 



Inhabits the four quarters of the globe.

Resembles C. edusa, but paler; border browner, divided by fine 

 yellow nervures. The primaries are broadly yellow on the edge ;
