illustration (fig. 1, c). When fully mature the larva attains a total 
length of about 2 inches. A lateral view of the larva in its burrow

This species derives its name from the spotted appearance of the 
moth, illustrated at figure 1, a, 6. There is great diversity in the 
size of the two sexes, the female (a), which is a heavy-bodied moth 
and a very feeble flyer, being much the larger. It will be noticed that

session of broad bipectinate or feathery antenne. The wings are 
semitransparent and white, thickly dotted with blackish spots 
which are more or less distinctly tinged, giving them a dark blue or 
greenish cast. The thorax is marked with six large black spots and 
one small one, the latter being located in the center. The female has 
a wing expanse of upwards of one and a half inches, while that of the 
male is much less. 
An empty pupa-case in its cell in the wood is shown in the illustra-
