anterior legs, so grooved as to have,them practically without strength at 
all, render this genus peculiar. Similar to it is Zanclognatha ; here also 
the °¥\ of some of the species have the tufts and excavation of Hermuinza, 
but not all are so modified. 
In addition to the modified anterior legs, the proportionately long 
median and posterior pairs, with the unequal and slender spurs dist- 
inguish this section. The spurs are more weak and slender than in WVoc- 
tua, and are clothed to the tip with scales. 
Copto-nemis Ze)l, which is unknown to me except from descriptions 
seems to be peculiar by the form of the posterior tibia, which is said to be 
decidedly bent inwardly just below the knee. 
Pailthis is another genus peculiar i in some respects. The general font 
of the legs is like Herminza, and the sexual tuftings are identical ; the 
lappet covering the excavation of anterior tibia is unusually small, the 
spinulation of tarsi present but almost obsolete and the claw of the tarsi 
proportionately very small. The posterior femur has an excavation on 
the upper side from before the middle to the tip. 
Bomolocha seems to have the peculiarities of this section only, among 
which are the brushes on the anterior legs of S of some of the species, 
Plathypena has the anterior coxze 3 as long as the femora, but does 
not otherwise differ from the other genera of this section. 
Sufficierit has now been given to show the drift of variation. This 
in the coxa is a gradual increase in size and mobility from the highest 
group to the lowest, in which it equals the femur in the anterior leg, and 
is only slightly less moveable, 
The femur seems to gain in length, and loose in weight as we go 
downward, and while only slightly grooved in the higher groups, is dec— 
idedly so in the lower. 
The tibize vary in different ways: the anterior, from the form shown 
in dAgrots to the form shown in Z/iwopzs, in one direction, and to the 
form shown in Zermimia in the other: Schima is the type of a very 
peculiar group, diverging from the type (Vocfwa in many respects other 
than that of the legs: it is indoubtedly a Heliothid but closely related to 
the Plustadae and Acontadae, giving each of these groups for the nonce 
family terminations. The median tibize seem to present a smaller range 
of variation, becoming only longer and more slender. The posterior 
seems to present no greater range of variation ; but the spurs do. Weak 
short and equal in the Gomdycid group they attain their greatest strength 
in the type /Voc/ua, increasing in length but becoming more weak in the
