fore wings have the yellow spots of the upper side re- 

 peated, the spots more confluent. The hind wings have 

 a conspicuous silvery white band in the middle, nearly 

 reaching the costa, but not so near the inner margin. 

 This band is narrow in the anterior portion, but broadly 

 expanded in the middle, and rounded posteriorly, so as 

 to be somewhat flask-shaped. Palpi brown, slightly 

 yellowish beneath. 



The larva of this species is to be found on the common 

 locust, rose acacia, Wistaria, and in the South on a species 

 of wild bean. When young, it cuts into the edge of a 

 leaf, and, drawing the flap over and fastening it with 

 silk, makes for itself a retreat, within which it stays. 

 As it increases in size, a larger section is cut in the leaf; 

 and, when this will no longer serve the purpose of pro- 

 tection, two or more leaves are fastened together. The 

 larvae feed mostly at night, keeping themselves concealed 

 within their retreats during the daytime. 



The egg is nearly globular, flattened at the base, with 

 fifteen ridges from base to apex ; diameter, .04 of an 

 inch. Color white, with a bright red spot at the apex, 

 and a ring of the same color a little above the middle. 

 The duration of this period is about four days. 



The young larva is .1 of an inch long, orange; the 

 head short, a little oblique, black ; joint 2 dark brown ; 

 a few hairs scattered over the body. Before the close of 

 this period the body shows a profusion of fine elevations. 



In nine days from hatching the larva moults the first 

 time, when it is .2 of an inch long, with the colors the 

 same as during the preceding period, except that the 

 second segment is pale reddish brown, with a central 

 transverse dark brown stripe.
