lives in the manner of other larvae. It 
will be wise, however, to verify this 
notion. (Y'ol. II. p. 4.) 
Dicycla. 
The place of the only species of this 
genus has been very various. I had put 
it, though with much hesitation, in the 
genus Cymatophora, but I have since 
recognized that it was badly placed there, 
and that it partook of all the characters 
of the family Cosmidae. Its beautiful 
larva much resembles those of Euperia 
and Cusmia. From its youth it lives 
in packets of leaves, which it fastens 
together at the extremity of the branches 
of oak, and which it does not quit till 
ready to change to a chrysalis. (Vol. II. 
p. 7.) 
Cosinia. 
This genus is divided into two very 
distinct groups. The first group (com- 
prising only one European species — Ira- 
pezina) has many relations with the 
genus Euperia. The larvae have much 
resemblance with those of the Orlhosidse, 
they only live shut up when they are 
young ; at least when nearly full grown 
they quit their retreat. They are carni- 
vorous, attacking their own species. 
The second group constitutes the Cos- 
miae proper: their larvae live shut up 
after the manner of Dicycla. They are 
very moniliform and much attenuated in 
front. I have not remarked that they 
are hostile to other larvae. The perfect 
insects are very pretty and are marked 
with lively colours. They fly with 
vivacity at dusk. (Vol. II. p. 9.) 
Family Hadenio.e. 
This is one of the most numerous 
families of the Nocture, but not one of 
tbe best characterized. The family of 
the Hadenidae, in fact, is connected with 
the Orlhosidse, the Xylinidae and the 
Aparaidre by such delicate gradations, 
that it is often difficult to point out the 
precise spot where each ought to stop ; 
this, however, is only a reproduction on 
a small scale of what occurs throughout 
Entomology, and even in general Zo- 
ology : this does not prevent the great 
majority of the species and the genera of 
the family from having a peculiar ap- 
pearance, of which I will attempt to give 
an idea. 
The larvae of the Hadenidae are gene- 
rally of rather lively colours and with the 
markings distinct, in that respect coming 
midway between those of the Apamidae 
and those of Xylinidae. I may add 
that they are always very cylindric, 
smooth, and without any eminence (only 
that ihe genera Miselia and Valeria are 
exceptions to this general rule). They 
all live exclusively on leaves, and are 
not as careful to avoid light as those of 
the Apamidre. Those which live on 
trees simply shelter themselves under the 
leaves. Those of the genus Dianthecia 
conceal themselves in the interior of the 
capsules of the Caryophyllaceae. Those of 
the geuus Hecatera prefer the flowers to 
the leaves. The larva of the genus 
Ayriapis conceals itself in the chinks of 
bark ; others extend themselves on stems 
of low plants, where they remain, as 
though glued, for hours. The larvae are 
found everywhere, even in our gardens, 
where they do not cause much mischief. 
They are generally in the larvae state in 
the summer time ; some, however, live 
through the winter. All enter the earth 
to change to chrysalis, and rarely do they 
take the trouble to construct a silken 
cocoon. An oval cavity, smooth within, 
and easily broken by the least touch, is 
sufficient to contain them. 
The perfect insects approach nearest 
to the Orthosidre ; they differ from them, 
however, by the palpi, always better de- 
veloped, and rather ascending than 
straight or drooping ; by the reniform stig- 
ma, which is not clouded with black ; and 
by the subterminal line, almost always 
broken into an M in the middle. There
