The adult, or beetle, is slightly over a quarter of an inch long, gen- 
erally of a yellowish or yellowish-brown color, with three somewhat 
indistinct brownish-black stripes on the wings. It is shown natural 
size at c, and enlarged at k, in figure 1. 
The eggs are placed on the lower side of the leaves in vertical 
clusters of from 5 to 20 or more eggs to each cluster, closely 
arranged in two or three irregular rows. They are oblong-oval in 
shape, tapering to a rather obtuse point, orange-yellow in color, and

the exterior surface is covered with beautiful hexagonal reticula- 
tions. They are shown natural size on the leaf at a, and much 
enlarged at e, with the reticulated surface still more enlarged at f. 
The larva is elongate, reaching a length of about half an inch, and 
when newly hatched is nearly black. As it increases in size it be- 
comes, with each shedding of the skin, more distinctly marked with 
yellow, and when mature the yellow predominates, occurring as a 
broad dorsal stripe and two lateral stripes. The larva is represented 
natural size on the leaves, and somewhat enlarged at g, with por- 
tions still more enlarged at A and 7 in the figure.
