trees, from the end of May till the middle of July. It resem. 
bles a hornet, and is of the same size and has the same colours 
only they are not quite so bright. | When this moth is just 
hatched, its wings are ferruginous; but its scales, light an¢ 
caducous, fall as soon as the insect begins to fly. The caterpillar, 
which lives in the trunks or roots of willows and poplar-trees, is 
of a yellowish colour. The pupa is long, of a brownish colour, 
enclosed in a cocoon composed. of design saw-dust, the pro- 
duct of the caterpillar’s erosions. 
In the middle of summer the meadows are frequented by moths, 
with brilliant black and velvety wings, marked with red, which 
fly heavily and only for a short time together. They remain 
by motionless during the great heat of the day. These are the 
Zygene, or Burnets, of the family of the! 
Zygemde. The Ram Sphinx of Geoffr oy, 
or the Six-spot Burnet-moth (Zy, yyena) 
filipendule) (Fig. 175), is common from| 
the end of June till the beginning of 
August. Its legs, antennz, head, and

Ye cocoon is boat-shaped, with longitudinal furrows, 
and is straw colour (Fig. 176). 
Next to Zygena comes Procris, a species which 
fly during the day in fields. | We will mention par- 
ticularly the Procris statices (Fig. 177), which is 
plentiful enough where it occurs between the middle 
of June and the middle of July, on the sides of 
hills.. Its fore wings, antenn, and the whole of its 
body, are of a blue green above. The same wings 
are of the same colour below, and the surfaces of 
the lower ones are of an ashy brown. 
The Sphinges, that is, those species that form the 
“themes family of the Sphingide, have received this general
