LEGS. 



The legs are generally very squammosely clolhed. The tarsi only 

 are spinulated, in some cases the hind tarsi only, but the tarsal hairs so 

 near^ 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 

 tars. ,t IS sometimes altogether wanting. The middle tibi^ are armed as 

 IS usual, the spurs being strong, the outer one generally much the lun-er 

 In a single instance the hind tibi^ have the end pair' of spurs onh" a 

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

 careful and repeated observation. 



The feet are a-clawed, the claws sharp, rounded, sickle-shaped w,th 

 an angular projection at the middle of the concave side. 1 he foot' itself 

 between the bases of the claws is furnished with a prominent projectm.. 

 pad. an organ which we have not hitherto observed in the LepiJoptera 

 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.
