 under-side of the leaves of the Cowslip (Primula vert's) 

 or Primrose (Primula vulgaris}. The larva may be found 

 from June till August or September, the winter being 

 passed in the pupal stage. The imagines come out in 

 June.

NEMEOBIUS LUCINA. 



The larva is woodlouse-shaped (Fig. 240). The colour of 

 the head is shiny orange-brown, of the body dark yellowish- 

 brown down to the spiracles paler below them. The 

 body is downy and, especially on the back, bears many 

 warts, each of which emits a bundle of stiff, curved hairs. 

 There is a dark, interrupted dorsal stripe of blackish 

 hairs, and on each side are two lateral ones. The spiracles 

 are outlined in black.
