In the fascea/e on the contrary, the primary characters become indefinite, 
weak, hardly worthy of close study, while the tendency to secondary 
characters becomes marked. ‘There is an especial leaning to tuftings or 
other modifications of the legs, many of which have long been known, 
but—as in the case of Catocala—have been only recently brought to the 
attention of entomologists. Remigza latipes indicates by its name the 
effects of the ubial and tarsal tuftings, while under the name Cop/ocnemia, 
Zeller described as a Delwid the contorted and tufted posterior tibia of 
Pleonectypiera Grote. In the Deltoid genera the modifications of leg 
structure are confined to the anterior pair, and extend to a complete 
change in the type of the structure. In Hypena and Bomolocha there is 
little modification. The cox are grooved to allow the femur to be 
closely applied to it, the femur is a mere shell into which the tibia can 
be almost completely concealed. The tarsi are normal, and the tibial 
epi; hysis is close to the base of that joint, and of rather small size. The 
figure (1) shows the fore leg of Plathypena* scabra. 
Megachyta lituralis indicates the type more usually found in the 
Hlerminiine. The coxa isa mere shell, concave anteriorly to receive 
the convexity of the femur, which has a brush of comparatively short 
hair near the base, at rest folded into the concavity of the under side. 
The tibia is modified into a flat chitinous process which begins at the 
epiphysis, the first tarsal joint being here inserted, and nearly equalling 
in length the femur. This chitinous process of the tibia is clothed with 
long scales and hair, but no tuft or pencil of hair. This structure is 
shown at figure 2, and marks the simplest form of this type. 
Chytolita morbidalts is after the same general type, but marks an im- 
portant change. The coxa is as before, but there is a pencil of long hair 
inserted at the base, resung in the concavity, and capable of being spread 
fan-like. The femur here has the concavity upward, and at the tip is a 
thick pencil of long hair spreading out fan-like, as in the figure, and 
normally reposing in the concavity. The tibial structure is as before, 
save that the clothing of hair 1s much longer and more dense, much 
more so than shown in the figure (fig. 3). The Ist tarsal joint is long as 
in JJegachyfa. When in repose, the pencils of hair folded, the femur 
closely appressed to the coxa, no part of this structure is visible, and the 
tibial process meeting the casual view and densely clothed, is usually 
considered the folded tuft. The structure in some European Herminia 
is identical, or nearly so. 
* In this paper I use the generic terms used in Mr. Grote’s catalogue as a matter 
of convenience, since synonymical matter is better left to the systematic part of the 
work.
