they are black with a common white band near their 
middle; and the discal 
veins are usually white 
and broadly bordered with 
black. There are great 
variations in the width of 
the white band on the 
wings. The larva feeds on 
the leaves of oak; it is 
brownish black, with a lat¬ 
eral yellow stripe; and is 
armed on each segment with large branching spines. This 
species pertains to the eastern part of the continent ; but 
there are several western species belonging to the genus. 
In the West there occur also two species of the genus 
Pseudohazis (Pseu-do-ha'zis). These are P. hera (P. he'ra), in 
which the ground-color of the wings is white (Plate IV), and 
P . eglanterina (P. eg-lan-te-ri'na), in which the ground-color 
is brown. Both species are spotted and striped with black. 
In each the abdomen is ringed with black; there is a large 
discal spot on each wing, which frequently has a white center 
due to white scales borne by the discal vein. The base of 
the wings is dusky. There is a transverse band at the end 
of the basal third, which is sometimes wanting on the hind 
wings; and a broader, wavy, transverse band crossing both 
wings at the end of the basal two thirds ; and on each wing 
there is a series of six or seven triangular black spots situ¬ 
ated on the ends of the veins, at the outer margin of the 
wing. It should be said that both in the ground-color and 
in the markings these two forms vary much ; and it is possi¬ 
ble that they are merely varieties of one species.

The Royal-moths. 
The Royal-moths are stout-bodied and hairy, with sunken 
heads and strong wings. The species are of medium or large
