LEGS. 
The legs are generally very squammosely clothed. The tarsi only 
are spinulated, in some cases the hind tarsi only, but the tarsal hairs so 
nearly appear like spines that it is difficult to tell the difference save in 
carefully prepared specimens and under a strong magnifying power. In 
all cases the spinulation is most decided on the hind tarsi. In the other 
tarsi it is sometimes altogether wanting. The middle tibize are armed as 
is usual, the spurs being strong, the outer one generally much the longer. 
In a single instance the hind tibia have the end pair of spurs only, a 
variation so remarkable in so small a family that we assert it only after 
careful and repeated observation. 
The feet are 2-clawed, the claws sharp, rounded, sickle-shaped, with 
an angular projection at the middle of the concave side. ‘The foot itself 
~ between the bases of the claws is furnished with a prominent projecting 
pad, an organ which we have not hitherto observed in the Lepidoptera. 
From the base of the claws above a number of long slender spines pro- 
ject, curved somewhat inwardly about the foot. 
The following synopsis, as well as what has been said above, is 
based upon the species of North America only.
