: The BOMB YCIDA. 
The Fox Motu (Bombyx rub). 
This is very common on heathy ground in every locality 
where I have collected. The moth is on the wing in June and 
July. The larva lives through the winter, and changes to pupa 
_ about the end of April. 
The Oak Eccar (Lombyx quercus). 
The larva feeds on Hawthorn, Birch, Willow, and on many 
other plants. This moth is on the wing in the sunshine; I have 
never seen the female flying, although I have taken many of them 
They are common at Orton and at Newby Cross from about the 
end of June until the middle of August. 
The DRINKER (Odonestis potatoria). 
The larva is very like that of the Oak Eggar. It feeds on 
grass, and it spins a yellow cocoon, pointed at both ends. The 
moth is on the wing in July and August.

The EMPEROR Motu (Saturnia carpini). 
The larva feeds on Heath, Willow, Birch, and Hawthorn, 
It is full grown about the end of August, when it spins a light- 
coloured cocoon, shaped like a pear, where it passes the winter. 
The moth is on the wing from the-end of April until the middle of 
_ August. The male is on the wing in the day-time. The female I 
have never seen on the wing, although I have found many at rest. 
They are common at Todhills, Houghton, Kingmoor, Newby 
Cross, and Orton.
