MODERH SYSTEM. 
Sp. 1. Cos. Ligniperda (goat moth). 
Phuleena (Bombyx) Cossus. Limit;. 
Inhabits Europe. The larva feeds on the internal parts of the willow, 
ash, and oak. The celebrated Lyonnett has immortalized himself by 
his laborious work on the anatomy of the larva and perfect insect. 
The caterpillar diffuses a scent, by which its residence may fre- 
quently be made known to those passing such trees as are much in- 
fested by it. It remains three years in this state, when it spins a 
strong web intermixed with particles of wood, and changes into 
the chrysalis, which it does in the month of May; and in June the 
perfect insect may lie found sticking to the trunks of trees (gene- 
rally willows) early in the morning and in the evening. 
1 once found the larva in an old oak near Norwood, in the month 
of January. Mr. Standish informs me, that those which feed on the 
wood of the oak are paler in colour than those which feed on the 
willow.
