 markings than pilosellte ; but neither in British nor

 identical.

 tum, generally in a company. The ground-colour of 

 the larva is dirty yellow or greenish, covered with 

 knobbed bristles and long white hairs ; on the back of 

 the abdominal segments is a double row of red or brown 

 longitudinal marks ; head honey-yellow. Frey.
