hardly conceive how they can be contained in so narrow 
a compass: Eriogaster Catar is a moth of this descrip- 
tion?. And others smaller in size lodge themselves in 
apartments apparently much more spacious than neces- 
sary. ‘The transparent hammock-like cocoons of Hepi- 
olus Humuli and Euprepia villica, two other moths, 
would contain several of their pupse. I possess one in 
which the pupa is suspended in the centre, that is ten 
times its size, and not very short in dimensions of that 
of Attacus Paphia, a giant silk-moth. The largest co- 
coon I ever read or heard of, is that thus described by 
Mr. Hobhouse in his Travels : *“* Depending,” says he, 
‘“‘from the boughs of the pines, near the Attic mountain 
Parnes, and stretching across from tree to tree so as to 
obstruct our passage, were the pods, thrice as big as a 
turkeys egg! and the thick webs of a chrysalis, whose 
moth must be far larger than any of those in our coun- 
try.” If this statement is correct, and I am not aware 
that there is any reason for doubting it, the cocoon must 
be vastly larger than the pupa, or the moth it produced 
would far exceed in size any yet known. Perhaps how- 
ever, as this gentleman is probably no entomologist, 
what he took for a cocoon might be a nidus, in which 
many larvae were associated, of the nature of those for- 
merly described *. 
With regard to jgure, the majority are like those of 
the silk-worm, of a shape more or less oval or elliptic: 
some, however, vary from this. That of Lasiocampa 
Rubi is oblong. I have one from New Holland some- 
what resembling an acorn, fixed to the twigs of some
