opposite the origin of the third vein. At the fork there is a pronounced 
yellow spot, which extends down each branch, on each of which there 
is another small yellow spot. At the junction of the branches 
of the fourth and fifth veins, a few golden scales are seen. 
The fringe is black even at these points. The fifth vein throughout is 
alternately yellow and black. Between the origin and the fork there 
are three yellow spots ; one yellow spot involves both branches, but 
mainly the upper; in addition, there are three yellow spots on each 
branch in addition to the yellow scales at the junction with the fringe. 
On first two-thirds of the sixth vein there are three yellow spots. The 
remainder of the vein is black scaled, with a few scattered golden 
scales about the middle. Except at the junction of the first vein, the 
fringe is black throughout. Wing scales long, narrow, lanceolate. 
Observations. Bred from two larvae, taken from a hole in the
