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 tibiae are armed as 

 is usual, the spurs being strong, the outer one generally much the longer. 

 In a single instance the hind tibioe have the end pair of spurs only, a 

 variation so remarkable in so small a family that we assert it only afier 

 careful and repeated observation. 



The feet are 2-cla\ved, 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 ol)served in the Lefiidoptera. 

 From the base of the claws above a number of long slender spines pro- 

 ject, curved somewhat inwardly about the fotit. 



The following synopsis, as well as what has been said above, is 

 based upon the species of North America only.
