Fydroeia metitans Bork, is peculiar by the tarsal claw which is like 
no other I have examined. 
Phiprosopus, Crambodes and Doryodes resemble each other very 
closely in structure of the legs, and show a decided downward step, The 
anterior coxais much more mobile and much longer: the posterior tibiz 
become longer and the legs as a whole are too long for the slight insects. 
Senta and Platysenta \ean that way, and lam a little at aloss to un- 
derstand exactly how these last, and Doryodes fit in between Macronuctua 
and Zeucania. 1 should place them lower in the scale. 
Plusiodonia resembles the foregoing in leg structure in some respects : 
the coxa is larger than in the preceeding generaand more mobile : the an- 
terior tibia is very decidedly excavated and the lappet small in proportion : 
the last mentioned genera al] agree in this character. P/ustodonta is in 
all respects an aberrant’ genus and its affinities seem to point in all di- 
rections: most distinctly downward however and it would not be ill 
placed after, instead of before P/wsia, and near to Aconfia. The tarsal claw 
is unusually small in proportion to the insect and its shape broad and flat 
with a sudden hook like termination showing in this respect also a tend- 
ency downward, as shown by a comparison with the claw of Hermunia. 
The legs of Zewcania are entirely unarmed but in some species 
densely hairy in the (j. 
Nephelodes is peculiar: the anterior femora are very slight and so de- 
cidedly excavate beneath, that only a shell remains : the tibia also is slight 
with the excavation well marked and the lappet extending from the base 
to the tip: the tarsi on the contrary are stout and very heavily spinose: 
the claws are simple. 
Scopelosoma has the legs compact and well clothed with hair: the 
tarsal claws are simple. 
Calocampa cineritia Grt. has the legs compact the tarsal claws very 
decidedly toothed, and the middle tibia with a slight excavation on the 
outer side; this I have not noticed elsewhere. 
Nycterophaeta has the tip of the anterior tibia peculiarly modified ; a 
flattened corneous projection terminates the tibia and is drawn out on 
each side making the appearance of two claws for which [at first mistook 
them. 
Cuculha to which the foregoing is nearly related has the anterior tibia 
armed in some of the European species.
