THE SUBSTITUTE. 
Winjfs, and feet, if I could find them, 
But from me these parts are hidden : 
Gentlemen are rarely met with, 
And ’tis said they are not scale-like, 
But have wings and long anteuuze. 
Lastly come the noisome plant-lice, 
Smother-flies the farmers call them. 
Smothering all the growth of summer. 
All the tender shoots of roses. 
Crowding till the shoots are hidden. 
Leaves and buds concealed by numbers. 
Anchored by their beaks sap-sucking. 
Winged and wingless all together; 
Their antennae long and waving. 
Gradual taper to the summit ; 
All their wings are quite transparent. 
When they have them, and not folded. 
But above their backs meet roof-like ; 
All their feet are but two-jointed. 
And their legs not Ibrmed for leaping : 
These are plant-lice, Aphidina.

Itusina. 
This well-characterised genus is 
related to the Caradrmid(£, Or- 
thosidce aiv\ Nocluidic. M. Bois- 
duval has placed it in the Amphy- 
piridcB. It appears to me to have 
least relation to these latter, es|ie- 
cially in its earlier stages. The 
larvm are somewhat inclined 
towards the first named groups, 
and live almost like them and at 
the same periods : they are as lazy 
and their growth is as slow : they 
are full fed in the middle of win- 
ter, and change to chrysalis in the 
spring. The perfect insect ap- 
pears in the middle of summer; it 
conceals itself amongst bushes, 
and flies even in mid-day when it 
is disturbed. (Vol. I., p. 255.) 
Ayrolis. 
This genus has been remodelled 
many times since its creation, and 
always unsuccessfully, which arises 
from the extreme diversity of the 
species which compose it, and that 
under their three states, and also 
from the want of precise notices 
of many of their larva;. The time 
will |)erhaps come when it can be 
divided into several very natural 
genera, l)ut I have said, and still 
think, that that lime has not yet 
arrived. I have therefore, left all 
the Ayrolis in one single genus, 
and have satisfied myself with 
establishing divi.sions which ap- 
peared to me to be most natural.
